If you are writing a scientific research paper or a book proposal, you need to know how to write an abstract, which summarizes the contents of the paper or book.

When researchers are looking for peer-reviewed papers to use in their studies, the first place they will check is the abstract to see if it applies to their work. Therefore, your abstract is one of the most important parts of your entire paper.

In this article, we’ll explain what an abstract is, what it should include, and how to write one.

An abstract is a concise summary of the details within a report. Some abstracts give more details than others, but the main things you’ll be talking about are why you conducted the research, what you did, and what the results show.

When a reader is deciding whether to read your paper completely, they will first look at the abstract. You need to be concise in your abstract and give the reader the most important information so they can determine if they want to read the whole paper.

Remember that an abstract is the last thing you’ll want to write for the research paper because it directly references parts of the report. If you haven’t written the report, you won’t know what to include in your abstract.

If you are writing a paper for a journal or an assignment, the publication or academic institution might have specific formatting rules for how long your abstract should be. However, if they don’t, most abstracts are between 150 and 300 words long.

A short word count means your writing has to be precise and without filler words or phrases. Once you’ve written a first draft, you can always use an editing tool, such as ProWritingAid, to identify areas where you can reduce words and increase readability.

If your abstract is over the word limit, and you’ve edited it but still can’t figure out how to reduce it further, your abstract might include some things that aren’t needed. Here’s a list of three elements you can remove from your abstract:

Discussion : You don’t need to go into detail about the findings of your research because your reader will find your discussion within the paper.

Definition of terms : Your readers are interested the field you are writing about, so they are likely to understand the terms you are using. If not, they can always look them up. Your readers do not expect you to give a definition of terms in your abstract.

References and citations : You can mention there have been studies that support or have inspired your research, but you do not need to give details as the reader will find them in your bibliography.

Good writing = better grades

ProWritingAid will help you improve the style, strength, and clarity of all your assignments.

If you’ve never written an abstract before, and you’re wondering how to write an abstract, we’ve got some steps for you to follow. It’s best to start with planning your abstract, so we’ve outlined the details you need to include in your plan before you write.

Remember to consider your audience when you’re planning and writing your abstract. They are likely to skim read your abstract, so you want to be sure your abstract delivers all the information they’re expecting to see at key points.

1. What Should an Abstract Include?

Abstracts have a lot of information to cover in a short number of words, so it’s important to know what to include. There are three elements that need to be present in your abstract:

Your context is the background for where your research sits within your field of study. You should briefly mention any previous scientific papers or experiments that have led to your hypothesis and how research develops in those studies.

Your hypothesis is your prediction of what your study will show. As you are writing your abstract after you have conducted your research, you should still include your hypothesis in your abstract because it shows the motivation for your paper.

Throughout your abstract, you also need to include keywords and phrases that will help researchers to find your article in the databases they’re searching. Make sure the keywords are specific to your field of study and the subject you’re reporting on, otherwise your article might not reach the relevant audience.

2. Can You Use First Person in an Abstract?

You might think that first person is too informal for a research paper, but it’s not. Historically, writers of academic reports avoided writing in first person to uphold the formality standards of the time. However, first person is more accepted in research papers in modern times.

If you’re still unsure whether to write in first person for your abstract, refer to any style guide rules imposed by the journal you’re writing for or your teachers if you are writing an assignment.

3. Abstract Structure

Some scientific journals have strict rules on how to structure an abstract, so it’s best to check those first. If you don’t have any style rules to follow, try using the IMRaD structure, which stands for Introduction, Methodology, Results, and Discussion.

Following the IMRaD structure, start with an introduction. The amount of background information you should include depends on your specific research area. Adding a broad overview gives you less room to include other details. Remember to include your hypothesis in this section.

The next part of your abstract should cover your methodology. Try to include the following details if they apply to your study:

What type of research was conducted?

How were the test subjects sampled?

What were the sample sizes?

What was done to each group?

How long was the experiment?

How was data recorded and interpreted?

Following the methodology, include a sentence or two about the results, which is where your reader will determine if your research supports or contradicts their own investigations.

The results are also where most people will want to find out what your outcomes were, even if they are just mildly interested in your research area. You should be specific about all the details but as concise as possible.

The last few sentences are your conclusion. It needs to explain how your findings affect the context and whether your hypothesis was correct. Include the primary take-home message, additional findings of importance, and perspective. Also explain whether there is scope for further research into the subject of your report.

Your conclusion should be honest and give the reader the ultimate message that your research shows. Readers trust the conclusion, so make sure you’re not fabricating the results of your research. Some readers won’t read your entire paper, but this section will tell them if it’s worth them referencing it in their own study.

4. How to Start an Abstract

The first line of your abstract should give your reader the context of your report by providing background information. You can use this sentence to imply the motivation for your research.

You don’t need to use a hook phrase or device in your first sentence to grab the reader’s attention. Your reader will look to establish relevance quickly, so readability and clarity are more important than trying to persuade the reader to read on.

5. How to Format an Abstract

Most abstracts use the same formatting rules, which help the reader identify the abstract so they know where to look for it.

Here’s a list of formatting guidelines for writing an abstract:

Stick to one paragraph

Use block formatting with no indentation at the beginning

Put your abstract straight after the title and acknowledgements pages

Use present or past tense, not future tense

There are two primary types of abstract you could write for your paper—descriptive and informative.

An informative abstract is the most common, and they follow the structure mentioned previously. They are longer than descriptive abstracts because they cover more details.

Descriptive abstracts differ from informative abstracts, as they don’t include as much discussion or detail. The word count for a descriptive abstract is between 50 and 150 words.

Here is an example of an informative abstract:

A growing trend exists for authors to employ a more informal writing style that uses “we” in academic writing to acknowledge one’s stance and engagement. However, few studies have compared the ways in which the first-person pronoun “we” is used in the abstracts and conclusions of empirical papers. To address this lacuna in the literature, this study conducted a systematic corpus analysis of the use of “we” in the abstracts and conclusions of 400 articles collected from eight leading electrical and electronic (EE) engineering journals. The abstracts and conclusions were extracted to form two subcorpora, and an integrated framework was applied to analyze and seek to explain how we-clusters and we-collocations were employed. Results revealed whether authors’ use of first-person pronouns partially depends on a journal policy. The trend of using “we” showed that a yearly increase occurred in the frequency of “we” in EE journal papers, as well as the existence of three “we-use” types in the article conclusions and abstracts: exclusive, inclusive, and ambiguous. Other possible “we-use” alternatives such as “I” and other personal pronouns were used very rarely—if at all—in either section. These findings also suggest that the present tense was used more in article abstracts, but the present perfect tense was the most preferred tense in article conclusions. Both research and pedagogical implications are proffered and critically discussed.

Wang, S., Tseng, W.-T., & Johanson, R. (2021). To We or Not to We: Corpus-Based Research on First-Person Pronoun Use in Abstracts and Conclusions. SAGE Open, 11(2).

Here is an example of a descriptive abstract:

From the 1850s to the present, considerable criminological attention has focused on the development of theoretically-significant systems for classifying crime. This article reviews and attempts to evaluate a number of these efforts, and we conclude that further work on this basic task is needed. The latter part of the article explicates a conceptual foundation for a crime pattern classification system, and offers a preliminary taxonomy of crime.

If you want to ensure your abstract is grammatically correct and easy to read, you can use ProWritingAid to edit it. The software integrates with Microsoft Word, Google Docs, and most web browsers, so you can make the most of it wherever you’re writing your paper.

Before you edit with ProWritingAid, make sure the suggestions you are seeing are relevant for your document by changing the document type to “Abstract” within the Academic writing style section.

You can use the Readability report to check your abstract for places to improve the clarity of your writing. Some suggestions might show you where to remove words, which is great if you’re over your word count.

We hope the five steps and examples we’ve provided help you write a great abstract for your research paper.

Formatting instructions

Follow these five steps to format your abstract in APA Style:

• Insert a running head (for a professional paper—not needed for a student paper) and page number.
• Set page margins to 1 inch (2.54 cm).
• Write “Abstract” (bold and centered) at the top of the page.
• Do not indent the first line.
• Double-space the text.
• Use a legible font like Times New Roman (12 pt.).
• Limit the length to 250 words.
• Indent the first line 0.5 inches.
• Write the label “Keywords:” (italicized).
• Write keywords in lowercase letters.
• Separate keywords with commas.
• Do not use a period after the keywords.

Prevent plagiarism. Run a free check.

The abstract is a self-contained piece of text that informs the reader what your research is about. It’s best to write the abstract after you’re finished with the rest of your paper.

The questions below may help structure your abstract. Try answering them in one to three sentences each.

• What is the problem? Outline the objective, research questions , and/or hypotheses .
• What has been done? Explain your research methods .
• What did you discover? Summarize the key findings and conclusions .
• What do the findings mean? Summarize the discussion and recommendations .

Guide: writing an abstract

At the end of the abstract, you may include a few keywords that will be used for indexing if your paper is published on a database. Listing your keywords will help other researchers find your work.

Choosing relevant keywords is essential. Try to identify keywords that address your topic, method, or population. APA recommends including three to five keywords.

An abstract is a concise summary of an academic text (such as a journal article or dissertation ). It serves two main purposes:

• To help potential readers determine the relevance of your paper for their own research.
• To communicate your key findings to those who don’t have time to read the whole paper.

Abstracts are often indexed along with keywords on academic databases, so they make your work more easily findable. Since the abstract is the first thing any reader sees, it’s important that it clearly and accurately summarizes the contents of your paper.

An APA abstract is around 150–250 words long. However, always check your target journal’s guidelines and don’t exceed the specified word count.

In an APA Style paper , the abstract is placed on a separate page after the title page (page 2).

Avoid citing sources in your abstract . There are two reasons for this:

• The abstract should focus on your original research, not on the work of others.
• The abstract should be self-contained and fully understandable without reference to other sources.

There are some circumstances where you might need to mention other sources in an abstract: for example, if your research responds directly to another study or focuses on the work of a single theorist. In general, though, don’t include citations unless absolutely necessary.

Abstract Writing: A Step-by-Step Guide With Tips & Examples

Table of Contents

Introduction

Abstracts of research papers have always played an essential role in describing your research concisely and clearly to researchers and editors of journals, enticing them to continue reading. However, with the widespread availability of scientific databases, the need to write a convincing abstract is more crucial now than during the time of paper-bound manuscripts.

Abstracts serve to "sell" your research and can be compared with your "executive outline" of a resume or, rather, a formal summary of the critical aspects of your work. Also, it can be the "gist" of your study. Since most educational research is done online, it's a sign that you have a shorter time for impressing your readers, and have more competition from other abstracts that are available to be read.

The APCI (Academic Publishing and Conferences International) articulates 12 issues or points considered during the final approval process for conferences & journals and emphasises the importance of writing an abstract that checks all these boxes (12 points). Since it's the only opportunity you have to captivate your readers, you must invest time and effort in creating an abstract that accurately reflects the critical points of your research.

With that in mind, let’s head over to understand and discover the core concept and guidelines to create a substantial abstract. Also, learn how to organise the ideas or plots into an effective abstract that will be awe-inspiring to the readers you want to reach.

What is Abstract? Definition and Overview

The word "Abstract' is derived from Latin abstractus meaning "drawn off." This etymological meaning also applies to art movements as well as music, like abstract expressionism. In this context, it refers to the revealing of the artist's intention.

Based on this, you can determine the meaning of an abstract: A condensed research summary. It must be self-contained and independent of the body of the research. However, it should outline the subject, the strategies used to study the problem, and the methods implemented to attain the outcomes. The specific elements of the study differ based on the area of study; however, together, it must be a succinct summary of the entire research paper.

Abstracts are typically written at the end of the paper, even though it serves as a prologue. In general, the abstract must be in a position to:

• Describe the paper.
• Identify the problem or the issue at hand.
• Explain to the reader the research process, the results you came up with, and what conclusion you've reached using these results.
• Include keywords to guide your strategy and the content.

Furthermore, the abstract you submit should not reflect upon any of  the following elements:

• Examine, analyse or defend the paper or your opinion.
• What you want to study, achieve or discover.
• Be redundant or irrelevant.

After reading an abstract, your audience should understand the reason - what the research was about in the first place, what the study has revealed and how it can be utilised or can be used to benefit others. You can understand the importance of abstract by knowing the fact that the abstract is the most frequently read portion of any research paper. In simpler terms, it should contain all the main points of the research paper.

What is the Purpose of an Abstract?

Abstracts are typically an essential requirement for research papers; however, it's not an obligation to preserve traditional reasons without any purpose. Abstracts allow readers to scan the text to determine whether it is relevant to their research or studies. The abstract allows other researchers to decide if your research paper can provide them with some additional information. A good abstract paves the interest of the audience to pore through your entire paper to find the content or context they're searching for.

Abstract writing is essential for indexing, as well. The Digital Repository of academic papers makes use of abstracts to index the entire content of academic research papers. Like meta descriptions in the regular Google outcomes, abstracts must include keywords that help researchers locate what they seek.

Types of Abstract

Informative and Descriptive are two kinds of abstracts often used in scientific writing.

A descriptive abstract gives readers an outline of the author's main points in their study. The reader can determine if they want to stick to the research work, based on their interest in the topic. An abstract that is descriptive is similar to the contents table of books, however, the format of an abstract depicts complete sentences encapsulated in one paragraph. It is unfortunate that the abstract can't be used as a substitute for reading a piece of writing because it's just an overview, which omits readers from getting an entire view. Also, it cannot be a way to fill in the gaps the reader may have after reading this kind of abstract since it does not contain crucial information needed to evaluate the article.

To conclude, a descriptive abstract is:

• A simple summary of the task, just summarises the work, but some researchers think it is much more of an outline
• Typically, the length is approximately 100 words. It is too short when compared to an informative abstract.
• A brief explanation but doesn't provide the reader with the complete information they need;
• An overview that omits conclusions and results

An informative abstract is a comprehensive outline of the research. There are times when people rely on the abstract as an information source. And the reason is why it is crucial to provide entire data of particular research. A well-written, informative abstract could be a good substitute for the remainder of the paper on its own.

A well-written abstract typically follows a particular style. The author begins by providing the identifying information, backed by citations and other identifiers of the papers. Then, the major elements are summarised to make the reader aware of the study. It is followed by the methodology and all-important findings from the study. The conclusion then presents study results and ends the abstract with a comprehensive summary.

In a nutshell, an informative abstract:

• Has a length that can vary, based on the subject, but is not longer than 300 words.
• Contains all the content-like methods and intentions
• Offers evidence and possible recommendations.

Informative Abstracts are more frequent than descriptive abstracts because of their extensive content and linkage to the topic specifically. You should select different types of abstracts to papers based on their length: informative abstracts for extended and more complex abstracts and descriptive ones for simpler and shorter research papers.

What are the Characteristics of a Good Abstract?

• A good abstract clearly defines the goals and purposes of the study.
• It should clearly describe the research methodology with a primary focus on data gathering, processing, and subsequent analysis.
• A good abstract should provide specific research findings.
• It presents the principal conclusions of the systematic study.
• It should be concise, clear, and relevant to the field of study.
• A well-designed abstract should be unifying and coherent.
• It is easy to grasp and free of technical jargon.
• It is written impartially and objectively.

What are the various sections of an ideal Abstract?

By now, you must have gained some concrete idea of the essential elements that your abstract needs to convey . Accordingly, the information is broken down into six key sections of the abstract, which include:

An Introduction or Background

Research methodology, objectives and goals, limitations.

Let's go over them in detail.

The introduction, also known as background, is the most concise part of your abstract. Ideally, it comprises a couple of sentences. Some researchers only write one sentence to introduce their abstract. The idea behind this is to guide readers through the key factors that led to your study.

It's understandable that this information might seem difficult to explain in a couple of sentences. For example, think about the following two questions like the background of your study:

• What is currently available about the subject with respect to the paper being discussed?
• What isn't understood about this issue? (This is the subject of your research)

While writing the abstract’s introduction, make sure that it is not lengthy. Because if it crosses the word limit, it may eat up the words meant to be used for providing other key information.

Research methodology is where you describe the theories and techniques you used in your research. It is recommended that you describe what you have done and the method you used to get your thorough investigation results. Certainly, it is the second-longest paragraph in the abstract.

In the research methodology section, it is essential to mention the kind of research you conducted; for instance, qualitative research or quantitative research (this will guide your research methodology too) . If you've conducted quantitative research, your abstract should contain information like the sample size, data collection method, sampling techniques, and duration of the study. Likewise, your abstract should reflect observational data, opinions, questionnaires (especially the non-numerical data) if you work on qualitative research.

The research objectives and goals speak about what you intend to accomplish with your research. The majority of research projects focus on the long-term effects of a project, and the goals focus on the immediate, short-term outcomes of the research. It is possible to summarise both in just multiple sentences.

In stating your objectives and goals, you give readers a picture of the scope of the study, its depth and the direction your research ultimately follows. Your readers can evaluate the results of your research against the goals and stated objectives to determine if you have achieved the goal of your research.

In the end, your readers are more attracted by the results you've obtained through your study. Therefore, you must take the time to explain each relevant result and explain how they impact your research. The results section exists as the longest in your abstract, and nothing should diminish its reach or quality.

One of the most important things you should adhere to is to spell out details and figures on the results of your research.

Instead of making a vague assertion such as, "We noticed that response rates varied greatly between respondents with high incomes and those with low incomes", Try these: "The response rate was higher for high-income respondents than those with lower incomes (59 30 percent vs. 30 percent in both cases; P<0.01)."

You're likely to encounter certain obstacles during your research. It could have been during data collection or even during conducting the sample . Whatever the issue, it's essential to inform your readers about them and their effects on the research.

Research limitations offer an opportunity to suggest further and deep research. If, for instance, you were forced to change for convenient sampling and snowball samples because of difficulties in reaching well-suited research participants, then you should mention this reason when you write your research abstract. In addition, a lack of prior studies on the subject could hinder your research.

Your conclusion should include the same number of sentences to wrap the abstract as the introduction. The majority of researchers offer an idea of the consequences of their research in this case.

Your conclusion should include three essential components:

• A significant take-home message.
• Corresponding important findings.
• The Interpretation.

Even though the conclusion of your abstract needs to be brief, it can have an enormous influence on the way that readers view your research. Therefore, make use of this section to reinforce the central message from your research. Be sure that your statements reflect the actual results and the methods you used to conduct your research.

Good Abstract Examples

Abstract example #1.

Children’s consumption behavior in response to food product placements in movies.

The abstract:

"Almost all research into the effects of brand placements on children has focused on the brand's attitudes or behavior intentions. Based on the significant differences between attitudes and behavioral intentions on one hand and actual behavior on the other hand, this study examines the impact of placements by brands on children's eating habits. Children aged 6-14 years old were shown an excerpt from the popular film Alvin and the Chipmunks and were shown places for the item Cheese Balls. Three different versions were developed with no placements, one with moderately frequent placements and the third with the highest frequency of placement. The results revealed that exposure to high-frequency places had a profound effect on snack consumption, however, there was no impact on consumer attitudes towards brands or products. The effects were not dependent on the age of the children. These findings are of major importance to researchers studying consumer behavior as well as nutrition experts as well as policy regulators."

Abstract Example #2

Social comparisons on social media: The impact of Facebook on young women’s body image concerns and mood. The abstract:

"The research conducted in this study investigated the effects of Facebook use on women's moods and body image if the effects are different from an internet-based fashion journal and if the appearance comparison tendencies moderate one or more of these effects. Participants who were female ( N = 112) were randomly allocated to spend 10 minutes exploring their Facebook account or a magazine's website or an appearance neutral control website prior to completing state assessments of body dissatisfaction, mood, and differences in appearance (weight-related and facial hair, face, and skin). Participants also completed a test of the tendency to compare appearances. The participants who used Facebook were reported to be more depressed than those who stayed on the control site. In addition, women who have the tendency to compare appearances reported more facial, hair and skin-related issues following Facebook exposure than when they were exposed to the control site. Due to its popularity it is imperative to conduct more research to understand the effect that Facebook affects the way people view themselves."

Abstract Example #3

The Relationship Between Cell Phone Use and Academic Performance in a Sample of U.S. College Students

"The cellphone is always present on campuses of colleges and is often utilised in situations in which learning takes place. The study examined the connection between the use of cell phones and the actual grades point average (GPA) after adjusting for predictors that are known to be a factor. In the end 536 students in the undergraduate program from 82 self-reported majors of an enormous, public institution were studied. Hierarchical analysis ( R 2 = .449) showed that use of mobile phones is significantly ( p < .001) and negative (b equal to -.164) connected to the actual college GPA, after taking into account factors such as demographics, self-efficacy in self-regulated learning, self-efficacy to improve academic performance, and the actual high school GPA that were all important predictors ( p < .05). Therefore, after adjusting for other known predictors increasing cell phone usage was associated with lower academic performance. While more research is required to determine the mechanisms behind these results, they suggest the need to educate teachers and students to the possible academic risks that are associated with high-frequency mobile phone usage."

Quick tips on writing a good abstract

There exists a common dilemma among early age researchers whether to write the abstract at first or last? However, it's recommended to compose your abstract when you've completed the research since you'll have all the information to give to your readers. You can, however, write a draft at the beginning of your research and add in any gaps later.

If you find abstract writing a herculean task, here are the few tips to help you with it:

1. Always develop a framework to support your abstract

Before writing, ensure you create a clear outline for your abstract. Divide it into sections and draw the primary and supporting elements in each one. You can include keywords and a few sentences that convey the essence of your message.

2. Review Other Abstracts

Abstracts are among the most frequently used research documents, and thousands of them were written in the past. Therefore, prior to writing yours, take a look at some examples from other abstracts. There are plenty of examples of abstracts for dissertations in the dissertation and thesis databases.

3. Avoid Jargon To the Maximum

When you write your abstract, focus on simplicity over formality. You should  write in simple language, and avoid excessive filler words or ambiguous sentences. Keep in mind that your abstract must be readable to those who aren't acquainted with your subject.

4. Focus on Your Research

It's a given fact that the abstract you write should be about your research and the findings you've made. It is not the right time to mention secondary and primary data sources unless it's absolutely required.

Conclusion: How to Structure an Interesting Abstract?

Abstracts are a short outline of your essay. However, it's among the most important, if not the most important. The process of writing an abstract is not straightforward. A few early-age researchers tend to begin by writing it, thinking they are doing it to "tease" the next step (the document itself). However, it is better to treat it as a spoiler.

The simple, concise style of the abstract lends itself to a well-written and well-investigated study. If your research paper doesn't provide definitive results, or the goal of your research is questioned, so will the abstract. Thus, only write your abstract after witnessing your findings and put your findings in the context of a larger scenario.

The process of writing an abstract can be daunting, but with these guidelines, you will succeed. The most efficient method of writing an excellent abstract is to centre the primary points of your abstract, including the research question and goals methods, as well as key results.

How to Write an Abstract in Research Papers (with Examples)

An abstract in research papers is a keyword-rich summary usually not exceeding 200-350 words. It can be considered the “face” of research papers because it creates an initial impression on the readers. While searching databases (such as PubMed) for research papers, a title is usually the first selection criterion for readers. If the title matches their search criteria, then the readers read the abstract, which sets the tone of the paper. Titles and abstracts are often the only freely available parts of research papers on journal websites. The pdf versions of full articles need to be purchased. Journal reviewers are often provided with only the title and abstract before they agree to review the complete paper. [ 1]  

Abstracts in research papers provide readers with a quick insight into what the paper is about to help them decide whether they want to read it further or not. Abstracts are the main selling points of articles and therefore should be carefully drafted, accurately highlighting the important aspects. [ 2]  

This article will help you identify the important components and provide tips on how to write an abstract in research papers effectively

What is an Abstract?  

An abstract in research papers can be defined as a synopsis of the paper. It should be clear, direct, self-contained, specific, unbiased, and concise. These summaries are published along with the complete research paper and are also submitted to conferences for consideration for presentation.  

Abstracts are of four types and journals can follow any of these formats: [ 2]  

• Structured  
• Unstructured  
• Descriptive  
• Informative  

Structured abstracts are used by most journals because they are more organized and have clear sections, usually including introduction/background; objective; design, settings, and participants (or materials and methods); outcomes and measures; results; and conclusion. These headings may differ based on the journal or the type of paper. Clinical trial abstracts should include the essential items mentioned in the CONSORT (Consolidated Standards Of Reporting Trials) guidelines.  

Figure 1. Structured abstract example [3] 

Unstructured abstracts are common in social science, humanities, and physical science journals. They usually have one paragraph and no specific structure or subheadings. These abstracts are commonly used for research papers that don’t report original work and therefore have a more flexible and narrative style.  

Figure 2. Unstructured abstract example [3] 

Descriptive abstracts are short (75–150 words) and provide an outline with only the most important points of research papers. They are used for shorter articles such as case reports, reviews, and opinions where space is at a premium, and rarely for original investigations. These abstracts don’t present the results but mainly list the topics covered.  

Here’s a sample abstract . [ 4]  

“Design of a Radio-Based System for Distribution Automation”  

A new survey by the Maryland Public Utilities Commission suggests that utilities have not effectively explained to consumers the benefits of smart meters. The two-year study of 86,000 consumers concludes that the long-term benefits of smart meters will not be realized until consumers understand the benefits of shifting some of their power usage to off-peak hours in response to the data they receive from their meters. The study presents recommendations for utilities and municipal governments to improve customer understanding of how to use the smart meters effectively.  

Keywords: smart meters, distribution systems, load, customer attitudes, power consumption, utilities  

Informative abstracts (structured or unstructured) give a complete detailed summary, including the main results, of the research paper and may or may not have subsections.   

Figure 3. Informative abstract example [5] 

Purpose of Abstracts in Research    

Abstracts in research have two main purposes—selection and indexing. [ 6,7]  

• Selection : Abstracts allow interested readers to quickly decide the relevance of a paper to gauge if they should read it completely.   
• Indexing : Most academic journal databases accessed through libraries enable you to search abstracts, allowing for quick retrieval of relevant articles and avoiding unnecessary search results. Therefore, abstracts must necessarily include the keywords that researchers may use to search for articles.  

Thus, a well-written, keyword-rich abstract can p ique readers’ interest and curiosity and help them decide whether they want to read the complete paper. It can also direct readers to articles of potential clinical and research interest during an online search.  

Contents of Abstracts in Research  

Abstracts in research papers summarize the main points of an article and are broadly categorized into four or five sections. Here are some details on how to write an abstract .   

Introduction/Background and/or Objectives  

This section should provide the following information:  

• What is already known about the subject?  
• What is not known about the subject or what does the study aim to investigate?  

The hypothesis or research question and objectives should be mentioned here. The Background sets the context for the rest of the paper and its length should be short so that the word count could be saved for the Results or other information directly pertaining to the study. The objective should be written in present or past simple tense.  

Examples:  

The antidepressant efficacy of desvenlafaxine (DV) has been established in 8-week, randomized controlled trials. The present study examined the continued efficacy of DV across 6 months of maintenance treatment . [ 1]  

Objective: To describe gastric and breast cancer risk estimates for individuals with CDH1 variants.  

Design, Setting, and Participants (or Materials and Methods)  

This section should provide information on the processes used and should be written in past simple tense because the process is already completed.  

A few important questions to be answered include:  

• What was the research design and setting?  
• What was the sample size and how were the participants sampled?  
• What treatments did the participants receive?  
• What were the data collection and data analysis dates?  
• What was the primary outcome measure?  

Hazard ratios (HRs) were estimated for each cancer type and used to calculate cumulative risks and risks per decade of life up to age 80 years.  

This section, written in either present or past simple tense, should be the longest and should describe the main findings of the study. Here’s an example of how descriptive the sentences should be:  

Avoid: Response rates differed significantly between diabetic and nondiabetic patients.  

Better: The response rate was higher in nondiabetic than in diabetic patients (49% vs 30%, respectively; P<0.01).  

This section should include the following information:  

• Total number of patients (included, excluded [exclusion criteria])  
• Primary and secondary outcomes, expressed in words, and supported by numerical data  
• Data on adverse outcomes  

Example: [ 8]  

In total, 10.9% of students were reported to have favorable study skills. The minimum score was found for preparation for examination domain. Also, a significantly positive correlation was observed between students’ study skills and their Grade Point Average (GPA) of previous term (P=0.001, r=0.269) and satisfaction with study skills (P=0.001, r=0.493).  

Conclusions  

Here, authors should mention the importance of their findings and also the practical and theoretical implications, which would benefit readers referring to this paper for their own research. Present simple tense should be used here.  

Examples: [ 1,8]  

The 9.3% prevalence of bipolar spectrum disorders in students at an arts university is substantially higher than general population estimates. These findings strengthen the oft-expressed hypothesis linking creativity with affective psychopathology.  

The findings indicated that students’ study skills need to be improved. Given the significant relationship between study skills and GPA, as an index of academic achievement, and satisfaction, it is necessary to promote the students’ study skills. These skills are suggested to be reinforced, with more emphasis on weaker domains.  

When to Write an Abstract  

In addition to knowing how to write an abstract , you should also know when to write an abstract . It’s best to write abstracts once the paper is completed because this would make it easier for authors to extract relevant parts from every section.  

Abstracts are usually required for: [ 7]    

• submitting articles to journals  
• applying for research grants   
• writing book proposals  
• completing and submitting dissertations  
• submitting proposals for conference papers  

Mostly, the author of the entire work writes the abstract (the first author, in works with multiple authors). However, there are professional abstracting services that hire writers to draft abstracts of other people’s work.   

How to Write an Abstract (Step-by-Step Process)  

Here are some key steps on how to write an abstract in research papers: [ 9]  

• Write the abstract after you’ve finished writing your paper.  
• Select the major objectives/hypotheses and conclusions from your Introduction and Conclusion sections.  
• Select key sentences from your Methods section.  
• Identify the major results from the Results section.  
• Paraphrase or re-write the sentences selected in steps 2, 3, and 4 in your own words into one or two paragraphs in the following sequence: Introduction/Objective, Methods, Results, and Conclusions. The headings may differ among journals, but the content remains the same.  
• Ensure that this draft does not contain: a.   new information that is not present in the paper b.   undefined abbreviations c.   a discussion of previous literature or reference citations d.   unnecessary details about the methods used  
• Remove all extra information and connect your sentences to ensure that the information flows well, preferably in the following order: purpose; basic study design, methodology and techniques used; major findings; summary of your interpretations, conclusions, and implications. Use section headings for structured abstracts.  
• Ensure consistency between the information presented in the abstract and the paper.  
• Check to see if the final abstract meets the guidelines of the target journal (word limit, type of abstract, recommended subheadings, etc.) and if all the required information has been included.  

Choosing Keywords for Abstracts  

Keywords [ 2] are the important and repeatedly used words and phrases in research papers and can help indexers and search engines find papers relevant to your requirements. Easy retrieval would help in reaching a wider audience and eventually gain more citations. In the fields of medicine and health, keywords should preferably be chosen from the Medical Subject Headings (MeSH) list of the US National Library of Medicine because they are used for indexing. These keywords need to be different from the words in the main title (automatically used for indexing) but can be variants of the terms/phrases used in the title, abstract, and the main text. Keywords should represent the content of your manuscript and be specific to your subject area.  

Basic tips for authors [ 10,11]  

• Read through your paper and highlight key terms or phrases that are most relevant and frequently used in your field, to ensure familiarity.  
• Several journals provide instructions about the length (eg, 3 words in a keyword) and maximum number of keywords allowed and other related rules. Create a list of keywords based on these instructions and include specific phrases containing 2 to 4 words. A longer string of words would yield generic results irrelevant to your field.  
• Use abbreviations, acronyms, and initializations if these would be more familiar.  
• Search with your keywords to ensure the results fit with your article and assess how helpful they would be to readers.  
• Narrow down your keywords to about five to ten, to ensure accuracy.  
• Finalize your list based on the maximum number allowed.  

  Few examples: [ 12]  

Important Tips for Writing an Abstract  

Here are a few tips on how to write an abstract to ensure that your abstract is complete, concise, and accurate. [ 1,2]  

• Write the abstract last.  
• Follow journal-specific formatting guidelines or Instructions to Authors strictly to ensure acceptance for publication.  
• Proofread the final draft meticulously to avoid grammatical or typographical errors.  
• Ensure that the terms or data mentioned in the abstract are consistent with the main text.  
• Include appropriate keywords at the end.

Do not include:  

• New information  
• Text citations to references  
• Citations to tables and figures  
• Generic statements  
• Abbreviations unless necessary, like a trial or study name  

Key Takeaways    

Here’s a quick snapshot of all the important aspects of how to write an abstract . [2]

• An abstract in research is a summary of the paper and describes only the main aspects. Typically, abstracts are about 200-350 words long.  
• Abstracts are of four types—structured, unstructured, descriptive, and informative.  
• Abstracts should be simple, clear, concise, independent, and unbiased (present both favorable and adverse outcomes).  
• They should adhere to the prescribed journal format, including word limits, section headings, number of keywords, fonts used, etc.  
• The terminology should be consistent with the main text.   
• Although the section heading names may differ for journals, every abstract should include a background and objective, analysis methods, primary results, and conclusions.  
• Nonstandard abbreviations, references, and URLs shouldn’t be included.  
• Only relevant and specific keywords should be used to ensure focused searches and higher citation frequency.  
• Abstracts should be written last after completing the main paper.  

Frequently Asked Questions   

Q1. Do all journals have different guidelines for abstracts?  

A1. Yes, all journals have their own specific guidelines for writing abstracts; a few examples are given in the following table. [ 6,13,14,15]  

Q2. What are the common mistakes to avoid when writing an abstract?  

A2. Listed below are a few mistakes that authors may make inadvertently while writing abstracts.  

• Copying sentences from the paper verbatim  

An abstract is a summary, which should be created by paraphrasing your own work or writing in your own words. Extracting sentences from every section and combining them into one paragraph cannot be considered summarizing.  

• Not adhering to the formatting guidelines  

Journals have special instructions for writing abstracts, such as word limits and section headings. These should be followed strictly to avoid rejections.  

• Not including the right amount of details in every section  

Both too little and too much information could discourage readers. For instance, if the Background has very little information, the readers may not get sufficient context to appreciate your research. Similarly, incomplete information in the Methods and a text-heavy Results section without supporting numerical data may affect the credibility of your research.  

• Including citations, standard abbreviations, and detailed measurements  

Typically, abstracts shouldn’t include these elements—citations, URLs, and abbreviations. Only nonstandard abbreviations are allowed or those that would be more familiar to readers than the expansions.  

• Including new information  

Abstracts should strictly include only the same information mentioned in the main text. Any new information should first be added to the text and then to the abstract only if necessary or if permitted by the word limit.  

• Not including keywords  

Keywords are essential for indexing and searching and should be included to increase the frequency of retrieval and citation.  

Q3. What is the difference between abstracts in research papers and conference abstracts? [16]  

A3. The table summarizes the main differences between research and conference abstracts.  

  Thus, abstracts are essential “trailers” that can market your research to a wide audience. The better and more complete the abstract the more are the chances of your paper being read and cited. By following our checklist and ensuring that all key elements are included, you can create a well-structured abstract that summarizes your paper accurately.

How to Write an Abstract | Steps & Examples

Published on 1 March 2019 by Shona McCombes . Revised on 10 October 2022 by Eoghan Ryan.

An abstract is a short summary of a longer work (such as a dissertation or research paper ). The abstract concisely reports the aims and outcomes of your research, so that readers know exactly what your paper is about.

Although the structure may vary slightly depending on your discipline, your abstract should describe the purpose of your work, the methods you’ve used, and the conclusions you’ve drawn.

One common way to structure your abstract is to use the IMRaD structure. This stands for:

• Introduction

Abstracts are usually around 100–300 words, but there’s often a strict word limit, so make sure to check the relevant requirements.

In a dissertation or thesis , include the abstract on a separate page, after the title page and acknowledgements but before the table of contents .

Hover over the different parts of the abstract to see how it is constructed.

This paper examines the role of silent movies as a mode of shared experience in the UK during the early twentieth century. At this time, high immigration rates resulted in a significant percentage of non-English-speaking citizens. These immigrants faced numerous economic and social obstacles, including exclusion from public entertainment and modes of discourse (newspapers, theater, radio).

Incorporating evidence from reviews, personal correspondence, and diaries, this study demonstrates that silent films were an affordable and inclusive source of entertainment. It argues for the accessible economic and representational nature of early cinema. These concerns are particularly evident in the low price of admission and in the democratic nature of the actors’ exaggerated gestures, which allowed the plots and action to be easily grasped by a diverse audience despite language barriers.

Keywords: silent movies, immigration, public discourse, entertainment, early cinema, language barriers.

You will almost always have to include an abstract when:

• Completing a thesis or dissertation
• Submitting a research paper to an academic journal
• Writing a book proposal
• Applying for research grants

It’s easiest to write your abstract last, because it’s a summary of the work you’ve already done. Your abstract should:

• Be a self-contained text, not an excerpt from your paper
• Be fully understandable on its own
• Reflect the structure of your larger work

Start by clearly defining the purpose of your research. What practical or theoretical problem does the research respond to, or what research question did you aim to answer?

You can include some brief context on the social or academic relevance of your topic, but don’t go into detailed background information. If your abstract uses specialised terms that would be unfamiliar to the average academic reader or that have various different meanings, give a concise definition.

After identifying the problem, state the objective of your research. Use verbs like “investigate,” “test,” “analyse,” or “evaluate” to describe exactly what you set out to do.

This part of the abstract can be written in the present or past simple tense  but should never refer to the future, as the research is already complete.

• This study will investigate the relationship between coffee consumption and productivity.
• This study investigates the relationship between coffee consumption and productivity.

Next, indicate the research methods that you used to answer your question. This part should be a straightforward description of what you did in one or two sentences. It is usually written in the past simple tense, as it refers to completed actions.

• Structured interviews will be conducted with 25 participants.
• Structured interviews were conducted with 25 participants.

Don’t evaluate validity or obstacles here — the goal is not to give an account of the methodology’s strengths and weaknesses, but to give the reader a quick insight into the overall approach and procedures you used.

Next, summarise the main research results . This part of the abstract can be in the present or past simple tense.

• Our analysis has shown a strong correlation between coffee consumption and productivity.
• Our analysis shows a strong correlation between coffee consumption and productivity.
• Our analysis showed a strong correlation between coffee consumption and productivity.

Depending on how long and complex your research is, you may not be able to include all results here. Try to highlight only the most important findings that will allow the reader to understand your conclusions.

Finally, you should discuss the main conclusions of your research : what is your answer to the problem or question? The reader should finish with a clear understanding of the central point that your research has proved or argued. Conclusions are usually written in the present simple tense.

• We concluded that coffee consumption increases productivity.
• We conclude that coffee consumption increases productivity.

If there are important limitations to your research (for example, related to your sample size or methods), you should mention them briefly in the abstract. This allows the reader to accurately assess the credibility and generalisability of your research.

If your aim was to solve a practical problem, your discussion might include recommendations for implementation. If relevant, you can briefly make suggestions for further research.

If your paper will be published, you might have to add a list of keywords at the end of the abstract. These keywords should reference the most important elements of the research to help potential readers find your paper during their own literature searches.

Be aware that some publication manuals, such as APA Style , have specific formatting requirements for these keywords.

It can be a real challenge to condense your whole work into just a couple of hundred words, but the abstract will be the first (and sometimes only) part that people read, so it’s important to get it right. These strategies can help you get started.

Read other abstracts

The best way to learn the conventions of writing an abstract in your discipline is to read other people’s. You probably already read lots of journal article abstracts while conducting your literature review —try using them as a framework for structure and style.

You can also find lots of dissertation abstract examples in thesis and dissertation databases .

Reverse outline

Not all abstracts will contain precisely the same elements. For longer works, you can write your abstract through a process of reverse outlining.

For each chapter or section, list keywords and draft one to two sentences that summarise the central point or argument. This will give you a framework of your abstract’s structure. Next, revise the sentences to make connections and show how the argument develops.

Write clearly and concisely

A good abstract is short but impactful, so make sure every word counts. Each sentence should clearly communicate one main point.

To keep your abstract or summary short and clear:

• Avoid passive sentences: Passive constructions are often unnecessarily long. You can easily make them shorter and clearer by using the active voice.
• Avoid long sentences: Substitute longer expressions for concise expressions or single words (e.g., “In order to” for “To”).
• Avoid obscure jargon: The abstract should be understandable to readers who are not familiar with your topic.
• Avoid repetition and filler words: Replace nouns with pronouns when possible and eliminate unnecessary words.
• Avoid detailed descriptions: An abstract is not expected to provide detailed definitions, background information, or discussions of other scholars’ work. Instead, include this information in the body of your thesis or paper.

If you’re struggling to edit down to the required length, you can get help from expert editors with Scribbr’s professional proofreading services .

Check your formatting

If you are writing a thesis or dissertation or submitting to a journal, there are often specific formatting requirements for the abstract—make sure to check the guidelines and format your work correctly. For APA research papers you can follow the APA abstract format .

Checklist: Abstract

The word count is within the required length, or a maximum of one page.

The abstract appears after the title page and acknowledgements and before the table of contents .

I have clearly stated my research problem and objectives.

I have briefly described my methodology .

I have summarized the most important results .

I have stated my main conclusions .

I have mentioned any important limitations and recommendations.

The abstract can be understood by someone without prior knowledge of the topic.

You've written a great abstract! Use the other checklists to continue improving your thesis or dissertation.

An abstract is a concise summary of an academic text (such as a journal article or dissertation ). It serves two main purposes:

• To help potential readers determine the relevance of your paper for their own research.
• To communicate your key findings to those who don’t have time to read the whole paper.

Abstracts are often indexed along with keywords on academic databases, so they make your work more easily findable. Since the abstract is the first thing any reader sees, it’s important that it clearly and accurately summarises the contents of your paper.

An abstract for a thesis or dissertation is usually around 150–300 words. There’s often a strict word limit, so make sure to check your university’s requirements.

The abstract is the very last thing you write. You should only write it after your research is complete, so that you can accurately summarize the entirety of your thesis or paper.

Avoid citing sources in your abstract . There are two reasons for this:

• The abstract should focus on your original research, not on the work of others.
• The abstract should be self-contained and fully understandable without reference to other sources.

There are some circumstances where you might need to mention other sources in an abstract: for example, if your research responds directly to another study or focuses on the work of a single theorist. In general, though, don’t include citations unless absolutely necessary.

The abstract appears on its own page, after the title page and acknowledgements but before the table of contents .

What this handout is about

This handout provides definitions and examples of the two main types of abstracts: descriptive and informative. It also provides guidelines for constructing an abstract and general tips for you to keep in mind when drafting. Finally, it includes a few examples of abstracts broken down into their component parts.

What is an abstract?

An abstract is a self-contained, short, and powerful statement that describes a larger work. Components vary according to discipline. An abstract of a social science or scientific work may contain the scope, purpose, results, and contents of the work. An abstract of a humanities work may contain the thesis, background, and conclusion of the larger work. An abstract is not a review, nor does it evaluate the work being abstracted. While it contains key words found in the larger work, the abstract is an original document rather than an excerpted passage.

Why write an abstract?

You may write an abstract for various reasons. The two most important are selection and indexing. Abstracts allow readers who may be interested in a longer work to quickly decide whether it is worth their time to read it. Also, many online databases use abstracts to index larger works. Therefore, abstracts should contain keywords and phrases that allow for easy searching.

Say you are beginning a research project on how Brazilian newspapers helped Brazil’s ultra-liberal president Luiz Ignácio da Silva wrest power from the traditional, conservative power base. A good first place to start your research is to search Dissertation Abstracts International for all dissertations that deal with the interaction between newspapers and politics. “Newspapers and politics” returned 569 hits. A more selective search of “newspapers and Brazil” returned 22 hits. That is still a fair number of dissertations. Titles can sometimes help winnow the field, but many titles are not very descriptive. For example, one dissertation is titled “Rhetoric and Riot in Rio de Janeiro.” It is unclear from the title what this dissertation has to do with newspapers in Brazil. One option would be to download or order the entire dissertation on the chance that it might speak specifically to the topic. A better option is to read the abstract. In this case, the abstract reveals the main focus of the dissertation:

This dissertation examines the role of newspaper editors in the political turmoil and strife that characterized late First Empire Rio de Janeiro (1827-1831). Newspaper editors and their journals helped change the political culture of late First Empire Rio de Janeiro by involving the people in the discussion of state. This change in political culture is apparent in Emperor Pedro I’s gradual loss of control over the mechanisms of power. As the newspapers became more numerous and powerful, the Emperor lost his legitimacy in the eyes of the people. To explore the role of the newspapers in the political events of the late First Empire, this dissertation analyzes all available newspapers published in Rio de Janeiro from 1827 to 1831. Newspapers and their editors were leading forces in the effort to remove power from the hands of the ruling elite and place it under the control of the people. In the process, newspapers helped change how politics operated in the constitutional monarchy of Brazil.

From this abstract you now know that although the dissertation has nothing to do with modern Brazilian politics, it does cover the role of newspapers in changing traditional mechanisms of power. After reading the abstract, you can make an informed judgment about whether the dissertation would be worthwhile to read.

Besides selection, the other main purpose of the abstract is for indexing. Most article databases in the online catalog of the library enable you to search abstracts. This allows for quick retrieval by users and limits the extraneous items recalled by a “full-text” search. However, for an abstract to be useful in an online retrieval system, it must incorporate the key terms that a potential researcher would use to search. For example, if you search Dissertation Abstracts International using the keywords “France” “revolution” and “politics,” the search engine would search through all the abstracts in the database that included those three words. Without an abstract, the search engine would be forced to search titles, which, as we have seen, may not be fruitful, or else search the full text. It’s likely that a lot more than 60 dissertations have been written with those three words somewhere in the body of the entire work. By incorporating keywords into the abstract, the author emphasizes the central topics of the work and gives prospective readers enough information to make an informed judgment about the applicability of the work.

When do people write abstracts?

• when submitting articles to journals, especially online journals
• when applying for research grants
• when writing a book proposal
• when completing the Ph.D. dissertation or M.A. thesis
• when writing a proposal for a conference paper
• when writing a proposal for a book chapter

Most often, the author of the entire work (or prospective work) writes the abstract. However, there are professional abstracting services that hire writers to draft abstracts of other people’s work. In a work with multiple authors, the first author usually writes the abstract. Undergraduates are sometimes asked to draft abstracts of books/articles for classmates who have not read the larger work.

Types of abstracts

There are two types of abstracts: descriptive and informative. They have different aims, so as a consequence they have different components and styles. There is also a third type called critical, but it is rarely used. If you want to find out more about writing a critique or a review of a work, see the UNC Writing Center handout on writing a literature review . If you are unsure which type of abstract you should write, ask your instructor (if the abstract is for a class) or read other abstracts in your field or in the journal where you are submitting your article.

Descriptive abstracts

A descriptive abstract indicates the type of information found in the work. It makes no judgments about the work, nor does it provide results or conclusions of the research. It does incorporate key words found in the text and may include the purpose, methods, and scope of the research. Essentially, the descriptive abstract describes the work being abstracted. Some people consider it an outline of the work, rather than a summary. Descriptive abstracts are usually very short—100 words or less.

Informative abstracts

The majority of abstracts are informative. While they still do not critique or evaluate a work, they do more than describe it. A good informative abstract acts as a surrogate for the work itself. That is, the writer presents and explains all the main arguments and the important results and evidence in the complete article/paper/book. An informative abstract includes the information that can be found in a descriptive abstract (purpose, methods, scope) but also includes the results and conclusions of the research and the recommendations of the author. The length varies according to discipline, but an informative abstract is rarely more than 10% of the length of the entire work. In the case of a longer work, it may be much less.

Here are examples of a descriptive and an informative abstract of this handout on abstracts . Descriptive abstract:

The two most common abstract types—descriptive and informative—are described and examples of each are provided.

Informative abstract:

Abstracts present the essential elements of a longer work in a short and powerful statement. The purpose of an abstract is to provide prospective readers the opportunity to judge the relevance of the longer work to their projects. Abstracts also include the key terms found in the longer work and the purpose and methods of the research. Authors abstract various longer works, including book proposals, dissertations, and online journal articles. There are two main types of abstracts: descriptive and informative. A descriptive abstract briefly describes the longer work, while an informative abstract presents all the main arguments and important results. This handout provides examples of various types of abstracts and instructions on how to construct one.

Which type should I use?

Your best bet in this case is to ask your instructor or refer to the instructions provided by the publisher. You can also make a guess based on the length allowed; i.e., 100-120 words = descriptive; 250+ words = informative.

How do I write an abstract?

The format of your abstract will depend on the work being abstracted. An abstract of a scientific research paper will contain elements not found in an abstract of a literature article, and vice versa. However, all abstracts share several mandatory components, and there are also some optional parts that you can decide to include or not. When preparing to draft your abstract, keep the following key process elements in mind:

• Reason for writing: What is the importance of the research? Why would a reader be interested in the larger work?
• Problem: What problem does this work attempt to solve? What is the scope of the project? What is the main argument/thesis/claim?
• Methodology: An abstract of a scientific work may include specific models or approaches used in the larger study. Other abstracts may describe the types of evidence used in the research.
• Results: Again, an abstract of a scientific work may include specific data that indicates the results of the project. Other abstracts may discuss the findings in a more general way.
• Implications: What changes should be implemented as a result of the findings of the work? How does this work add to the body of knowledge on the topic?

(This list of elements is adapted with permission from Philip Koopman, “How to Write an Abstract.” )

All abstracts include:

• A full citation of the source, preceding the abstract.
• The most important information first.
• The same type and style of language found in the original, including technical language.
• Key words and phrases that quickly identify the content and focus of the work.
• Clear, concise, and powerful language.

Abstracts may include:

• The thesis of the work, usually in the first sentence.
• Background information that places the work in the larger body of literature.
• The same chronological structure as the original work.

How not to write an abstract:

• Do not refer extensively to other works.
• Do not add information not contained in the original work.
• Do not define terms.

If you are abstracting your own writing

When abstracting your own work, it may be difficult to condense a piece of writing that you have agonized over for weeks (or months, or even years) into a 250-word statement. There are some tricks that you could use to make it easier, however.

Reverse outlining:

This technique is commonly used when you are having trouble organizing your own writing. The process involves writing down the main idea of each paragraph on a separate piece of paper– see our short video . For the purposes of writing an abstract, try grouping the main ideas of each section of the paper into a single sentence. Practice grouping ideas using webbing or color coding .

For a scientific paper, you may have sections titled Purpose, Methods, Results, and Discussion. Each one of these sections will be longer than one paragraph, but each is grouped around a central idea. Use reverse outlining to discover the central idea in each section and then distill these ideas into one statement.

Cut and paste:

To create a first draft of an abstract of your own work, you can read through the entire paper and cut and paste sentences that capture key passages. This technique is useful for social science research with findings that cannot be encapsulated by neat numbers or concrete results. A well-written humanities draft will have a clear and direct thesis statement and informative topic sentences for paragraphs or sections. Isolate these sentences in a separate document and work on revising them into a unified paragraph.

If you are abstracting someone else’s writing

When abstracting something you have not written, you cannot summarize key ideas just by cutting and pasting. Instead, you must determine what a prospective reader would want to know about the work. There are a few techniques that will help you in this process:

Identify key terms:

Search through the entire document for key terms that identify the purpose, scope, and methods of the work. Pay close attention to the Introduction (or Purpose) and the Conclusion (or Discussion). These sections should contain all the main ideas and key terms in the paper. When writing the abstract, be sure to incorporate the key terms.

Highlight key phrases and sentences:

Instead of cutting and pasting the actual words, try highlighting sentences or phrases that appear to be central to the work. Then, in a separate document, rewrite the sentences and phrases in your own words.

Don’t look back:

After reading the entire work, put it aside and write a paragraph about the work without referring to it. In the first draft, you may not remember all the key terms or the results, but you will remember what the main point of the work was. Remember not to include any information you did not get from the work being abstracted.

Revise, revise, revise

No matter what type of abstract you are writing, or whether you are abstracting your own work or someone else’s, the most important step in writing an abstract is to revise early and often. When revising, delete all extraneous words and incorporate meaningful and powerful words. The idea is to be as clear and complete as possible in the shortest possible amount of space. The Word Count feature of Microsoft Word can help you keep track of how long your abstract is and help you hit your target length.

Example 1: Humanities abstract

Kenneth Tait Andrews, “‘Freedom is a constant struggle’: The dynamics and consequences of the Mississippi Civil Rights Movement, 1960-1984” Ph.D. State University of New York at Stony Brook, 1997 DAI-A 59/02, p. 620, Aug 1998

This dissertation examines the impacts of social movements through a multi-layered study of the Mississippi Civil Rights Movement from its peak in the early 1960s through the early 1980s. By examining this historically important case, I clarify the process by which movements transform social structures and the constraints movements face when they try to do so. The time period studied includes the expansion of voting rights and gains in black political power, the desegregation of public schools and the emergence of white-flight academies, and the rise and fall of federal anti-poverty programs. I use two major research strategies: (1) a quantitative analysis of county-level data and (2) three case studies. Data have been collected from archives, interviews, newspapers, and published reports. This dissertation challenges the argument that movements are inconsequential. Some view federal agencies, courts, political parties, or economic elites as the agents driving institutional change, but typically these groups acted in response to the leverage brought to bear by the civil rights movement. The Mississippi movement attempted to forge independent structures for sustaining challenges to local inequities and injustices. By propelling change in an array of local institutions, movement infrastructures had an enduring legacy in Mississippi.

Now let’s break down this abstract into its component parts to see how the author has distilled his entire dissertation into a ~200 word abstract.

Example 2: Science Abstract

Luis Lehner, “Gravitational radiation from black hole spacetimes” Ph.D. University of Pittsburgh, 1998 DAI-B 59/06, p. 2797, Dec 1998

The problem of detecting gravitational radiation is receiving considerable attention with the construction of new detectors in the United States, Europe, and Japan. The theoretical modeling of the wave forms that would be produced in particular systems will expedite the search for and analysis of detected signals. The characteristic formulation of GR is implemented to obtain an algorithm capable of evolving black holes in 3D asymptotically flat spacetimes. Using compactification techniques, future null infinity is included in the evolved region, which enables the unambiguous calculation of the radiation produced by some compact source. A module to calculate the waveforms is constructed and included in the evolution algorithm. This code is shown to be second-order convergent and to handle highly non-linear spacetimes. In particular, we have shown that the code can handle spacetimes whose radiation is equivalent to a galaxy converting its whole mass into gravitational radiation in one second. We further use the characteristic formulation to treat the region close to the singularity in black hole spacetimes. The code carefully excises a region surrounding the singularity and accurately evolves generic black hole spacetimes with apparently unlimited stability.

This science abstract covers much of the same ground as the humanities one, but it asks slightly different questions.

Writing an abstract - a six point checklist (with samples)

Posted in: abstract , dissertations

The abstract is a vital part of any research paper. It is the shop front for your work, and the first stop for your reader. It should provide a clear and succinct summary of your study, and encourage your readers to read more. An effective abstract, therefore should answer the following questions:

• Why did you do this study or project?
• What did you do and how?
• What did you find?
• What do your findings mean?

So here's our run down of the key elements of a well-written abstract.

• Size - A succinct and well written abstract should be between approximately 100- 250 words.
• Background - An effective abstract usually includes some scene-setting information which might include what is already known about the subject, related to the paper in question (a few short sentences).
• Purpose  - The abstract should also set out the purpose of your research, in other words, what is not known about the subject and hence what the study intended to examine (or what the paper seeks to present).
• Methods - The methods section should contain enough information to enable the reader to understand what was done, and how. It should include brief details of the research design, sample size, duration of study, and so on.
• Results - The results section is the most important part of the abstract. This is because readers who skim an abstract do so to learn about the findings of the study. The results section should therefore contain as much detail about the findings as the journal word count permits.
• Conclusion - This section should contain the most important take-home message of the study, expressed in a few precisely worded sentences. Usually, the finding highlighted here relates to the primary outcomes of the study. However, other important or unexpected findings should also be mentioned. It is also customary, but not essential, to express an opinion about the theoretical or practical implications of the findings, or the importance of their findings for the field. Thus, the conclusions may contain three elements:
• The primary take-home message.
• Any additional findings of importance.
• Implications for future studies.

Example Abstract 2: Engineering Development and validation of a three-dimensional finite element model of the pelvic bone.

Abstract from: Dalstra, M., Huiskes, R. and Van Erning, L., 1995. Development and validation of a three-dimensional finite element model of the pelvic bone. Journal of biomechanical engineering, 117(3), pp.272-278.

And finally...  A word on abstract types and styles

Abstract types can differ according to subject discipline. You need to determine therefore which type of abstract you should include with your paper. Here are two of the most common types with examples.

Informative Abstract

The majority of abstracts are informative. While they still do not critique or evaluate a work, they do more than describe it. A good informative abstract acts as a surrogate for the work itself. That is, the researcher presents and explains all the main arguments and the important results and evidence in the paper. An informative abstract includes the information that can be found in a descriptive abstract [purpose, methods, scope] but it also includes the results and conclusions of the research and the recommendations of the author. The length varies according to discipline, but an informative abstract is usually no more than 300 words in length.

Descriptive Abstract A descriptive abstract indicates the type of information found in the work. It makes no judgements about the work, nor does it provide results or conclusions of the research. It does incorporate key words found in the text and may include the purpose, methods, and scope of the research. Essentially, the descriptive abstract only describes the work being summarised. Some researchers consider it an outline of the work, rather than a summary. Descriptive abstracts are usually very short, 100 words or less.

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Scholars often write abstracts for various applications: conference presentations may require an abstract or other short summary for a program; journal articles almost always require abstracts; invited talks and lectures are often advertised using an abstract. While the application may necessarily change the length of the abstract (a conference program may only allow for 50-75 words, for instance), the purpose and structure remains fairly constant.

Abstracts are generally kept brief (approximately 150-200 words). They differ by field, but in general, they need to summarize the article so that readers can decide if it is relevant to their work. The typical abstract includes these elements:

• A statement of the problem and objectives
• A statement of the significance of the work
• A summary of employed methods or your research approach
• A summary of findings or conclusions of the study
• A description of the implications of the findings

Regardless of field, abstract authors should explain the purpose of the work, methods used, the results and the conclusions that can be drawn. However, each field purports slightly different ways to structure the abstract. A reliable strategy is to write the abstract as a condensed version of your article, with 1-2 sentences summarizing each major section. This means that in many of the sciences and a large portion of the humanities, abstracts follow a version of the IMRAD structure: Introduction, Methods, Results, and Discussion.

Most scientific journals require authors to submit such abstracts. It is generally advisable to write the abstract in the English language. That is because most papers in other languages, especially Asian nations, tend to publish an English abstract with common search engines, such as, the MLA site.

Example Abstract

This example abstract follows the IMRAD structure closely. The first two sentences are the introduction and background information. Sentences 3-5 describe the methods used in the study. Sentence 6 summarizes the results, while the last two sentences summarize the discussion and conclusion of the study; they also indicate the significance of the results.

Usability and User-Centered Theory for 21 st Century OWLs — by Dana Lynn Driscoll, H. Allen Brizee, Michael Salvo, and Morgan Sousa from The Handbook of Research on Virtual Workplaces and the New Nature of Business Practices . Eds. Kirk St. Amant and Pavel Zemlansky. Hershey, PA: Idea Group Publishing, 2008.

This article describes results of usability research conducted on the Purdue Online Writing Lab (OWL). The Purdue OWL is an information-rich educational website that provides free writing resources to users worldwide. Researchers conducted two generations of usability tests. In the first test, participants were asked to navigate the OWL and answer questions. Results of the first test and user-centered scholarship indicated that a more user-centered focus would improve usability. The second test asked participants to answer writing-related questions using both the OWL website and a user-centered OWL prototype. Participants took significantly less time to find information using the prototype and reported a more positive response to the user-centered prototype than the original OWL. Researchers conclude that a user-centered website is more effective and can be a model for information-rich online resources. Researchers also conclude that usability research can be a productive source of ideas, underscoring the need for participatory invention.

How to Write an Abstract for a Research Paper | Examples

What is a research paper abstract?

Research paper abstracts summarize your study quickly and succinctly to journal editors and researchers and prompt them to read further. But with the ubiquity of online publication databases, writing a compelling abstract is even more important today than it was in the days of bound paper manuscripts.

Abstracts exist to “sell”  your work, and they could thus be compared to the “executive summary” of a business resume: an official briefing on what is most important about your research. Or the “gist” of your research. With the majority of academic transactions being conducted online, this means that you have even less time to impress readers–and increased competition in terms of other abstracts out there to read.

The APCI (Academic Publishing and Conferences International) notes that there are  12 questions or “points” considered in the selection process  for journals and conferences and stresses the importance of having an abstract that ticks all of these boxes. Because it is often the ONLY chance you have to convince readers to keep reading, it is important that you spend time and energy crafting an abstract that faithfully represents the central parts of your study and captivates your audience.

With that in mind, follow these suggestions when structuring and writing your abstract, and learn how exactly to put these ideas into a solid abstract that will captivate your target readers.

Before Writing Your Abstract

How long should an abstract be.

All abstracts are written with the same essential objective: to give a summary of your study. But there are two basic styles of abstract: descriptive and informative . Here is a brief delineation of the two:

Of the two types of abstracts, informative abstracts are much more common, and they are widely used for submission to journals and conferences. Informative abstracts apply to lengthier and more technical research and are common in the sciences, engineering, and psychology, while descriptive abstracts are more likely used in humanities and social science papers. The best method of determining which abstract type you need to use is to follow the instructions for journal submissions and to read as many other published articles in those journals as possible.

Research Abstract Guidelines and Requirements

As any article about research writing will tell you, authors must always closely follow the specific guidelines and requirements indicated in the Guide for Authors section of their target journal’s website. The same kind of adherence to conventions should be applied to journal publications, for consideration at a conference, and even when completing a class assignment.

Each publisher has particular demands when it comes to formatting and structure. Here are some common questions addressed in the journal guidelines:

• Is there a maximum or minimum word/character length?
• What are the style and formatting requirements?
• What is the appropriate abstract type?
• Are there any specific content or organization rules that apply?

There are of course other rules to consider when composing a research paper abstract. But if you follow the stated rules the first time you submit your manuscript, you can avoid your work being thrown in the “circular file” right off the bat.

Identify Your Target Readership

The main purpose of your abstract is to lead researchers to the full text of your research paper. In scientific journals, abstracts let readers decide whether the research discussed is relevant to their own interests or study. Abstracts also help readers understand your main argument quickly. Consider these questions as you write your abstract:

• Are other academics in your field the main target of your study?
• Will your study perhaps be useful to members of the general public?
• Do your study results include the wider implications presented in the abstract?

Outlining and Writing Your Abstract

What to include in an abstract.

Just as your  research paper title  should cover as much ground as possible in a few short words, your abstract must cover  all  parts of your study in order to fully explain your paper and research. Because it must accomplish this task in the space of only a few hundred words, it is important not to include ambiguous references or phrases that will confuse the reader or mislead them about the content and objectives of your research. Follow these  dos  and  don’ts  when it comes to what kind of writing to include:

• Avoid acronyms or abbreviations since these will need to be explained in order to make sense to the reader, which takes up valuable abstract space. Instead, explain these terms in the Introduction section of the main text.
• Only use references to people or other works if they are well-known. Otherwise, avoid referencing anything outside of your study in the abstract.
• Never include tables, figures, sources, or long quotations in your abstract; you will have plenty of time to present and refer to these in the body of your paper.

Use keywords in your abstract to focus your topic

A vital search tool is the research paper keywords section, which lists the most relevant terms directly underneath the abstract. Think of these keywords as the “tubes” that readers will seek and enter—via queries on databases and search engines—to ultimately land at their destination, which is your paper. Your abstract keywords should thus be words that are commonly used in searches but should also be highly relevant to your work and found in the text of your abstract. Include 5 to 10 important words or short phrases central to your research in both the abstract and the keywords section.

For example, if you are writing a paper on the prevalence of obesity among lower classes that crosses international boundaries, you should include terms like “obesity,” “prevalence,” “international,” “lower classes,” and “cross-cultural.” These are terms that should net a wide array of people interested in your topic of study. Look at our nine rules for choosing keywords for your research paper if you need more input on this.

Research Paper Abstract Structure

As mentioned above, the abstract (especially the informative abstract) acts as a surrogate or synopsis of your research paper, doing almost as much work as the thousands of words that follow it in the body of the main text. In the hard sciences and most social sciences, the abstract includes the following sections and organizational schema.

Each section is quite compact—only a single sentence or two, although there is room for expansion if one element or statement is particularly interesting or compelling. As the abstract is almost always one long paragraph, the individual sections should naturally merge into one another to create a holistic effect. Use the following as a checklist to ensure that you have included all of the necessary content in your abstract.

1) Identify your purpose and motivation

So your research is about rabies in Brazilian squirrels. Why is this important? You should start your abstract by explaining why people should care about this study—why is it significant to your field and perhaps to the wider world? And what is the exact purpose of your study; what are you trying to achieve? Start by answering the following questions:

• What made you decide to do this study or project?
• Why is this study important to your field or to the lay reader?
• Why should someone read your entire article?

In summary, the first section of your abstract should include the importance of the research and its impact on related research fields or on the wider scientific domain.

2) Explain the research problem you are addressing

Stating the research problem that your study addresses is the corollary to why your specific study is important and necessary. For instance, even if the issue of “rabies in Brazilian squirrels” is important, what is the problem—the “missing piece of the puzzle”—that your study helps resolve?

You can combine the problem with the motivation section, but from a perspective of organization and clarity, it is best to separate the two. Here are some precise questions to address:

• What is your research trying to better understand or what problem is it trying to solve?
• What is the scope of your study—does it try to explain something general or specific?
• What is your central claim or argument?

3) Discuss your research approach

Your specific study approach is detailed in the Methods and Materials section .  You have already established the importance of the research, your motivation for studying this issue, and the specific problem your paper addresses. Now you need to discuss  how  you solved or made progress on this problem—how you conducted your research. If your study includes your own work or that of your team, describe that here. If in your paper you reviewed the work of others, explain this here. Did you use analytic models? A simulation? A double-blind study? A case study? You are basically showing the reader the internal engine of your research machine and how it functioned in the study. Be sure to:

• Detail your research—include methods/type of the study, your variables, and the extent of the work
• Briefly present evidence to support your claim
• Highlight your most important sources

4) Briefly summarize your results

Here you will give an overview of the outcome of your study. Avoid using too many vague qualitative terms (e.g, “very,” “small,” or “tremendous”) and try to use at least some quantitative terms (i.e., percentages, figures, numbers). Save your qualitative language for the conclusion statement. Answer questions like these:

• What did your study yield in concrete terms (e.g., trends, figures, correlation between phenomena)?
• How did your results compare to your hypothesis? Was the study successful?
• Where there any highly unexpected outcomes or were they all largely predicted?

5) State your conclusion

In the last section of your abstract, you will give a statement about the implications and  limitations of the study . Be sure to connect this statement closely to your results and not the area of study in general. Are the results of this study going to shake up the scientific world? Will they impact how people see “Brazilian squirrels”? Or are the implications minor? Try not to boast about your study or present its impact as  too  far-reaching, as researchers and journals will tend to be skeptical of bold claims in scientific papers. Answer one of these questions:

• What are the exact effects of these results on my field? On the wider world?
• What other kind of study would yield further solutions to problems?
• What other information is needed to expand knowledge in this area?

After Completing the First Draft of Your Abstract

Revise your abstract.

The abstract, like any piece of academic writing, should be revised before being considered complete. Check it for  grammatical and spelling errors  and make sure it is formatted properly.

Get feedback from a peer

Getting a fresh set of eyes to review your abstract is a great way to find out whether you’ve summarized your research well. Find a reader who understands research papers but is not an expert in this field or is not affiliated with your study. Ask your reader to summarize what your study is about (including all key points of each section). This should tell you if you have communicated your key points clearly.

In addition to research peers, consider consulting with a professor or even a specialist or generalist writing center consultant about your abstract. Use any resource that helps you see your work from another perspective.

Consider getting professional editing and proofreading

While peer feedback is quite important to ensure the effectiveness of your abstract content, it may be a good idea to find an academic editor  to fix mistakes in grammar, spelling, mechanics, style, or formatting. The presence of basic errors in the abstract may not affect your content, but it might dissuade someone from reading your entire study. Wordvice provides English editing services that both correct objective errors and enhance the readability and impact of your work.

Additional Abstract Rules and Guidelines

Write your abstract after completing your paper.

Although the abstract goes at the beginning of your manuscript, it does not merely introduce your research topic (that is the job of the title), but rather summarizes your entire paper. Writing the abstract last will ensure that it is complete and consistent with the findings and statements in your paper.

Keep your content in the correct order

Both questions and answers should be organized in a standard and familiar way to make the content easier for readers to absorb. Ideally, it should mimic the overall format of your essay and the classic “introduction,” “body,” and “conclusion” form, even if the parts are not neatly divided as such.

Write the abstract from scratch

Because the abstract is a self-contained piece of writing viewed separately from the body of the paper, you should write it separately as well. Never copy and paste direct quotes from the paper and avoid paraphrasing sentences in the paper. Using new vocabulary and phrases will keep your abstract interesting and free of redundancies while conserving space.

Don’t include too many details in the abstract

Again, the density of your abstract makes it incompatible with including specific points other than possibly names or locations. You can make references to terms, but do not explain or define them in the abstract. Try to strike a balance between being specific to your study and presenting a relatively broad overview of your work.

Wordvice Resources

If you think your abstract is fine now but you need input on abstract writing or require English editing services (including paper editing ), then head over to the Wordvice academic resources page, where you will find many more articles, for example on writing the Results , Methods , and Discussion sections of your manuscript, on choosing a title for your paper , or on how to finalize your journal submission with a strong cover letter .

Importance of a Good Abstract

Sometimes your professor will ask you to include an abstract, or general summary of your work, with your research paper. The abstract allows you to elaborate upon each major aspect of the paper and helps readers decide whether they want to read the rest of the paper. Therefore, enough key information [e.g., summary results, observations, trends, etc.] must be included to make the abstract useful to someone who may want to examine your work.

How do you know when you have enough information in your abstract? A simple rule-of-thumb is to imagine that you are another researcher doing a similar study. Then ask yourself: if your abstract was the only part of the paper you could access, would you be happy with the amount of information presented there? Does it tell the whole story about your study? If the answer is "no" then the abstract likely needs to be revised.

Structure and Writing Style

I.  Types of Abstracts

To begin, you need to determine which type of abstract you should include with your paper. There are four general types.

Critical Abstract A critical abstract provides, in addition to describing main findings and information, a judgment or comment about the study’s validity, reliability, or completeness. The researcher evaluates the paper and often compares it with other works on the same subject. Critical abstracts are generally 400-500 words in length due to the additional interpretive commentary. These types of abstracts are used infrequently.

Descriptive Abstract A descriptive abstract indicates the type of information found in the work. It makes no judgments about the work, nor does it provide results or conclusions of the research. It does incorporate key words found in the text and may include the purpose, methods, and scope of the research. Essentially, the descriptive abstract only describes the work being summarized. Some researchers consider it an outline of the work, rather than a summary. Descriptive abstracts are usually very short, 100 words or less. Informative Abstract The majority of abstracts are informative. While they still do not critique or evaluate a work, they do more than describe it. A good informative abstract acts as a surrogate for the work itself. That is, the researcher presents and explains all the main arguments and the important results and evidence in the paper. An informative abstract includes the information that can be found in a descriptive abstract [purpose, methods, scope] but it also includes the results and conclusions of the research and the recommendations of the author. The length varies according to discipline, but an informative abstract is usually no more than 300 words in length.

Highlight Abstract A highlight abstract is specifically written to attract the reader’s attention to the study. No pretense is made of there being either a balanced or complete picture of the paper and, in fact, incomplete and leading remarks may be used to spark the reader’s interest. In that a highlight abstract cannot stand independent of its associated article, it is not a true abstract and, therefore, rarely used in academic writing.

II.  Writing Style

Use the active voice when possible , but note that much of your abstract may require passive sentence constructions. Regardless, write your abstract using concise, but complete, sentences. Get to the point quickly and always use the past tense because you are reporting on a study that has been completed.

Abstracts should be formatted as a single paragraph in a block format and with no paragraph indentations. In most cases, the abstract page immediately follows the title page. Do not number the page. Rules set forth in writing manual vary but, in general, you should center the word "Abstract" at the top of the page with double spacing between the heading and the abstract. The final sentences of an abstract concisely summarize your study’s conclusions, implications, or applications to practice and, if appropriate, can be followed by a statement about the need for additional research revealed from the findings.

Composing Your Abstract

Although it is the first section of your paper, the abstract should be written last since it will summarize the contents of your entire paper. A good strategy to begin composing your abstract is to take whole sentences or key phrases from each section of the paper and put them in a sequence that summarizes the contents. Then revise or add connecting phrases or words to make the narrative flow clearly and smoothly. Note that statistical findings should be reported parenthetically [i.e., written in parentheses].

Before handing in your final paper, check to make sure that the information in the abstract completely agrees with what you have written in the paper. Think of the abstract as a sequential set of complete sentences describing the most crucial information using the fewest necessary words. The abstract SHOULD NOT contain:

• A catchy introductory phrase, provocative quote, or other device to grab the reader's attention,
• Lengthy background or contextual information,
• Redundant phrases, unnecessary adverbs and adjectives, and repetitive information;
• Acronyms or abbreviations,
• References to other literature [say something like, "current research shows that..." or "studies have indicated..."],
• Using ellipticals [i.e., ending with "..."] or incomplete sentences,
• Jargon or terms that may be confusing to the reader,
• Citations to other works, and
• Any sort of image, illustration, figure, or table, or references to them.

Writing Tip

Never Cite Just the Abstract!

Citing to just a journal article's abstract does not confirm for the reader that you have conducted a thorough or reliable review of the literature. If the full-text is not available, go to the USC Libraries main page and enter the title of the article [NOT the title of the journal]. If the Libraries have a subscription to the journal, the article should appear with a link to the full-text or to the journal publisher page where you can get the article. If the article does not appear, try searching Google Scholar using the link on the USC Libraries main page. If you still can't find the article after doing this, contact a librarian or you can request it from our free i nterlibrary loan and document delivery service .

24 popular academic phrases to write your abstract (+ real examples)

A helpful strategy to write an academic abstract is to incorporate key academic phrases commonly used in abstracts of published papers. This way, you can learn from real examples and improve your abstract writing skills.

The different components of academic abstracts

Abstracts are brief summaries of conducted studies or research that are used in academic papers, theses, and dissertations. They tend to be around 100-300 words long, and are usually positioned right under the research title and before the introduction.

A straightforward process can be followed when writing an abstract since abstracts are generally structured similarly and address several key components.

Abstracts can be written in a structured or an unstructured format. Structured abstracts provide clear headings to organize the content, such demonstrated in the following example:

Even though unstructured abstracts do not use headings, they still adhere to a specific structure and address all key components that should be included.

How to Write an Abstract Step-by-Step: a Guide + Examples

Writing an abstract is one of the skills you need to master to succeed in your studies. An abstract is a summary of an academic text . It contains information about the aims and the outcomes of the research. The primary purpose of an abstract is to help readers understand what a particular paper is about. It serves as a sort of introduction to the paper. The usual length is about 150-300 words.

Types of abstract essays include descriptive, critical, highlight, and informative abstract.

🚦 How to Write an Abstract: Getting Started

There are several things to consider before you start writing an abstract.

• It would be best if you had your paper ready. This one should be a no-brainer, but it’s still worth mentioning. If you try to write your abstract first, chances are you’ll have to edit it a lot afterward.
• Make sure you’re aware of all the requirements : writing style, length, and the whole purpose of an abstract. All of these factors will influence the contents of your abstract. Again, it’s better to do everything right from the beginning than to edit your work later.
• Think of the audience . Remember the definition of an abstract? It helps readers understand what your work is about. You need to be aware of who’s going to read it. Are they going to be scientists who’ll use your abstract to decide whether your work is relevant? Or do you need to make your abstract easy to understand for anyone? Answering these kinds of questions will help you determine how your abstract will look.
• Decide on the type of abstract . This decision is an essential one. Therefore, we’ll talk about it in the next part of our guide.

📑 Abstract Structure & Types

There are two main types of abstracts: informative and descriptive. The former is also known as a complete abstract, while the latter contains less information. See more detailed information below.

This type of abstract writing is also known as a complete abstract . And it’s pretty self-explanatory. An informative abstract is a summary of a paper. It describes its purpose, methodology, background, results, and conclusion. It also includes information about the paper’s structure, its key thoughts, and the major topics discussed. How long should an informative abstract be? It usually sticks to around 250+ words. The completeness of the information provided in it makes it possible to use the informative abstract as an independent document. A format similar to informative abstracts is used to write short scientific reports. Apart from examples below, you can use a summary writing tool to generate your own and check out the structure using more materials.

Informative Abstract Example

The Internet of Things Provides Emerging Business Opportunities

Purpose: The Internet of Things (IoT) is a new phenomenon, so there is a lack of public and scientific understanding of what IoT is and what commercial opportunities it can offer for large companies and sole entrepreneurs. The article aims to stimulate creativity, thinking, and entrepreneurship in terms of IoT.

Methods: This article consists of three parts. In the first part, IoT is described as a wide socio-technical phenomenon. Second, this article suggests two approaches for establishing new business models using IoT: a disruptive and a sustainable approach. Third, the article concludes with a reflection on the time to which the future of IoT can be possibly predicted.

Scope: The article discusses different elements that comprise IoT in the physical, technological, and socioeconomic environments. Results: This discussion shows the limitations of the new business models approach that was examined in this article and suggests guidelines on the more efficient ways of using this approach.

Conclusions: The attempt to predict the future can prepare companies for various threats and opportunities. The envisioned outcomes and scenarios can help the entrepreneurs make the correct decisions for their businesses’ success.

This type of abstract is also called an indicative abstract, or a limited abstract. Again, the name says it all. This abstract type paints a general description of the paper without going into very in-depth details. In the case of an informative abstract, you can develop an opinion about the paper based on the abstract alone. With a descriptive abstract, though, you’ll still have to read the main work because the abstract will only provide a general idea without all the vital pieces of content. It’s more like a table of contents but written in the form of a paragraph. And it’s usually about 100-200 words long.

Descriptive Abstract Example

Exploring the Boundaries of the Social Sciences

Purpose: The concept of research boundaries has been critical in history, anthropology, sociology, social psychology, political science, and sociology. This article intends to explore this problem and analyze the relational processes hindered by the boundaries.

Methods: It addresses relatable processes in various research institutions and social locations. It also investigates the directions for further development, with a focus on the dependence between symbolic and social boundaries, their cultural mechanisms, hybridity and difference, and group classifications.

Scope: The article analyzes several works on social identity; class, ethnic, and gender inequality; professions and science; and national identities, communities, and territorial boundaries.

👣 Writing an Abstract Step by Step

You’ll need to write an abstract for almost any academic text: a thesis, a research paper, an article, etc. No matter what document you are working on, the abstract should be the last part you’ll write. Let’s learn what main components that any abstract contains and how to write them step by step.

Identify Your Aims

Tell your readers why your work matters and why it is important. Don’t go into details here. Concentrate on the crucial points. Note that this part should be written in the present or past simple tense, not the future, as your research is already done. The questions below can help you formulate your aims.

• Why did I decide to study this particular topic?
• What theoretical or practical problem does my research respond to?
• What is the social context of my work?
• Why are my key findings important?

Explain Your Methods

The next part of your abstract is to contain a short and straightforward description of your research. Explain what you did in one or two sentences. Do that using the past simple tense.

• Describe your research process. Mention the approach you decided to go with and all the data that was at your disposal.
• Give a short overview of the most important sources used for your paper.
• Mention the evidence that supports your claims, so the readers know there’s a foundation to what you’re saying.

Share Your Results

This is where the main difference between the two types of abstracts comes into play.

You see, it’s only informative abstracts that contain this information. So, if you’ve decided to go with the descriptive type, you may skip this step.

If stating the problem can be considered a question, then this part is the answer to that question. Describe all your general findings as well as the goal that you reached through your research. Support your words with arguments and hypotheses.

Write a Conclusion

Not only will this part be a logical finish to your abstract, but it will also make a smooth transition to its closure.

Explain what your findings mean and why they make your paper important. To simplify the task, use an article summary generator and just edit the resulting piece.

While this part is necessary both for informative and descriptive abstracts, it’s only the former that needs to answer the following questions:

• What implications does my work have?
• Are my findings specific or general?

✏️ Abstract FAQ

An abstract is a compressed view of the essential elements of a manuscript without added interpretation. It should consist of an introduction or background, purpose, methodology, results, and discussion, or another conclusion. An effective abstract is not a selection of manuscript sentences, but a reworded gist.

A presentation abstract shall provide an overview of the research as briefly as possible. It shall comprise context, objective, methodology, and findings. The total word count shall not exceed 250 words. You will present the research orally and visually at the conference, so the purpose is to raise the listeners’ curiosity rather than provide them with a summary of your work.

It should be an easy-to-read 250-word passage following the template:

• The topic and purpose of your research or invention.
• The problem you resolved or the hypothesis you examined.
• The scientific methods you used to implement point 2.
• The achieved results.
• Conclusions on the relevance and importance of your project.

Identify the problem you address and give the reasons that motivated you to conduct the investigation. Mention the gaps that require further research. Describe your methodology. Provide the main results and findings without further explanation. The total number of words in an abstract shall be given in the lab requirements.

An APA abstract is a brief, comprehensive summary of the contents of an article, research paper, dissertation, or report.

It is written in accordance with the guidelines of the American Psychological Association (APA), which is a widely used format in social and behavioral sciences. 

An APA abstract summarizes, usually in one paragraph of between 150–250 words, the major aspects of a research paper or dissertation in a prescribed sequence that includes:

• The rationale: the overall purpose of the study, providing a clear context for the research undertaken.
• Information regarding the method and participants: including materials/instruments, design, procedure, and data analysis.
• Main findings or trends: effectively highlighting the key outcomes of the hypotheses.
• Interpretations and conclusion(s): solidify the implications of the research.
• Keywords related to the study: assist the paper’s discoverability in academic databases.

The abstract should stand alone, be “self-contained,” and make sense to the reader in isolation from the main article.

The purpose of the abstract is to give the reader a quick overview of the essential information before reading the entire article. The abstract is placed on its own page, directly after the title page and before the main body of the paper.

Although the abstract will appear as the very first part of your paper, it’s good practice to write your abstract after you’ve drafted your full paper, so that you know what you’re summarizing.

Note : This page reflects the latest version of the APA Publication Manual (i.e., APA 7), released in October 2019.

Structure of the Abstract

[NOTE: DO NOT separate the components of the abstract – it should be written as a single paragraph. This section is separated to illustrate the abstract’s structure.]

1) The Rationale

One or two sentences describing the overall purpose of the study and the research problem(s) you investigated. You are basically justifying why this study was conducted.

• What is the importance of the research?
• Why would a reader be interested in the larger work?
• For example, are you filling a gap in previous research or applying new methods to take a fresh look at existing ideas or data?
• Women who are diagnosed with breast cancer can experience an array of psychosocial difficulties; however, social support, particularly from a spouse, has been shown to have a protective function during this time. This study examined the ways in which a woman’s daily mood, pain, and fatigue, and her spouse’s marital satisfaction predict the woman’s report of partner support in the context of breast cancer.
• The current nursing shortage, high hospital nurse job dissatisfaction, and reports of uneven quality of hospital care are not uniquely American phenomena.
• Students with special educational needs and disabilities (SEND) are more likely to exhibit behavioral difficulties than their typically developing peers. The aim of this study was to identify specific risk factors that influence variability in behavior difficulties among individuals with SEND.

2) The Method

Information regarding the participants (number, and population). One or two sentences outlining the method, explaining what was done and how. The method is described in the present tense.

• Pretest data from a larger intervention study and multilevel modeling were used to examine the effects of women’s daily mood, pain, and fatigue and average levels of mood, pain, and fatigue on women’s report of social support received from her partner, as well as how the effects of mood interacted with partners’ marital satisfaction.
• This paper presents reports from 43,000 nurses from more than 700 hospitals in the United States, Canada, England, Scotland, and Germany in 1998–1999.
• The study sample comprised 4,228 students with SEND, aged 5–15, drawn from 305 primary and secondary schools across England. Explanatory variables were measured at the individual and school levels at baseline, along with a teacher-reported measure of behavior difficulties (assessed at baseline and the 18-month follow-up).

3) The Results

One or two sentences indicating the main findings or trends found as a result of your analysis. The results are described in the present or past tense.

• Results show that on days in which women reported higher levels of negative or positive mood, as well as on days they reported more pain and fatigue, they reported receiving more support. Women who, on average, reported higher levels of positive mood tended to report receiving more support than those who, on average, reported lower positive mood. However, average levels of negative mood were not associated with support. Higher average levels of fatigue but not pain were associated with higher support. Finally, women whose husbands reported higher levels of marital satisfaction reported receiving more partner support, but husbands’ marital satisfaction did not moderate the effect of women’s mood on support.
• Nurses in countries with distinctly different healthcare systems report similar shortcomings in their work environments and the quality of hospital care. While the competence of and relation between nurses and physicians appear satisfactory, core problems in work design and workforce management threaten the provision of care.
• Hierarchical linear modeling of data revealed that differences between schools accounted for between 13% (secondary) and 15.4% (primary) of the total variance in the development of students’ behavior difficulties, with the remainder attributable to individual differences. Statistically significant risk markers for these problems across both phases of education were being male, eligibility for free school meals, being identified as a bully, and lower academic achievement. Additional risk markers specific to each phase of education at the individual and school levels are also acknowledged.

4) The Conclusion / Implications

A brief summary of your conclusions and implications of the results, described in the present tense. Explain the results and why the study is important to the reader.

• For example, what changes should be implemented as a result of the findings of the work?
• How does this work add to the body of knowledge on the topic?

Implications of these findings are discussed relative to assisting couples during this difficult time in their lives.

• Resolving these issues, which are amenable to managerial intervention, is essential to preserving patient safety and care of consistently high quality.
• Behavior difficulties are affected by risks across multiple ecological levels. Addressing any one of these potential influences is therefore likely to contribute to the reduction in the problems displayed.

The above examples of abstracts are from the following papers:

5) Keywords

APA style suggests including a list of keywords at the end of the abstract. This is particularly common in academic articles and helps other researchers find your work in databases.

Keywords in an abstract should be selected to help other researchers find your work when searching an online database. These keywords should effectively represent the main topics of your study. Here are some tips for choosing keywords:

Core Concepts: Identify the most important ideas or concepts in your paper. These often include your main research topic, the methods you’ve used, or the theories you’re discussing.

Specificity: Your keywords should be specific to your research. For example, suppose your paper is about the effects of climate change on bird migration patterns in a specific region. In that case, your keywords might include “climate change,” “bird migration,” and the region’s name.

Consistency with Paper: Make sure your keywords are consistent with the terms you’ve used in your paper. For example, if you use the term “adolescent” rather than “teen” in your paper, choose “adolescent” as your keyword, not “teen.”

Jargon and Acronyms: Avoid using too much-specialized jargon or acronyms in your keywords, as these might not be understood or used by all researchers in your field.

Synonyms: Consider including synonyms of your keywords to capture as many relevant searches as possible. For example, if your paper discusses “post-traumatic stress disorder,” you might include “PTSD” as a keyword.

Remember, keywords are a tool for others to find your work, so think about what terms other researchers might use when searching for papers on your topic.

The Abstract SHOULD NOT contain:

Lengthy background or contextual information: The abstract should focus on your research and findings, not general topic background.

Undefined jargon, abbreviations,  or acronyms: The abstract should be accessible to a wide audience, so avoid highly specialized terms without defining them.

Citations: Abstracts typically do not include citations, as they summarize original research.

Incomplete sentences or bulleted lists: The abstract should be a single, coherent paragraph written in complete sentences.

New information not covered in the paper: The abstract should only summarize the paper’s content.

Subjective comments or value judgments: Stick to objective descriptions of your research.

Excessive details on methods or procedures: Keep descriptions of methods brief and focused on main steps.

Speculative or inconclusive statements: The abstract should state the research’s clear findings, not hypotheses or possible interpretations.

• Any illustration, figure, table, or references to them . All visual aids, data, or extensive details should be included in the main body of your paper, not in the abstract. 
• Elliptical or incomplete sentences should be avoided in an abstract . The use of ellipses (…), which could indicate incomplete thoughts or omitted text, is not appropriate in an abstract.

APA Style for Abstracts

An APA abstract must be formatted as follows:

Include the running head aligned to the left at the top of the page (professional papers only) and page number. Note, student papers do not require a running head. On the first line, center the heading “Abstract” and bold (do not underlined or italicize). Do not indent the single abstract paragraph (which begins one line below the section title). Double-space the text. Use Times New Roman font in 12 pt. Set one-inch (or 2.54 cm) margins. If you include a “keywords” section at the end of the abstract, indent the first line and italicize the word “Keywords” while leaving the keywords themselves without any formatting.

How long should an APA abstract be?

An APA abstract should typically be between 150 to 250 words long. However, the exact length may vary depending on specific publication or assignment guidelines. It is crucial that it succinctly summarizes the essential elements of the work, including purpose, methods, findings, and conclusions.

Where does the abstract go in an APA paper?

In an APA formatted paper, the abstract is placed on its own page, directly after the title page and before the main body of the paper. It’s typically the second page of the document. It starts with the word “Abstract” (centered and not in bold) at the top of the page, followed by the text of the abstract itself.

What are the 4 C’s of abstract writing?

The 4 C’s of abstract writing are an approach to help you create a well-structured and informative abstract. They are:

Conciseness: An abstract should briefly summarize the key points of your study. Stick to the word limit (typically between 150-250 words for an APA abstract) and avoid unnecessary details.

Clarity: Your abstract should be easy to understand. Avoid jargon and complex sentences. Clearly explain the purpose, methods, results, and conclusions of your study.

Completeness: Even though it’s brief, the abstract should provide a complete overview of your study, including the purpose, methods, key findings, and your interpretation of the results.

Cohesion: The abstract should flow logically from one point to the next, maintaining a coherent narrative about your study. It’s not just a list of disjointed elements; it’s a brief story of your research from start to finish.

What is the abstract of a psychology paper?

An abstract in a psychology paper serves as a snapshot of the paper, allowing readers to quickly understand the purpose, methodology, results, and implications of the research without reading the entire paper. It is generally between 150-250 words long.

APA 7th Edition Style Guide

• Abstracts & Keywords
• Authors & Publication Dates
• Titles & Sources
• In-line, Within-Text Citation ch.8
• Is this a "real" journal? evaluating journals
• Tables and Figures
• Librarian contact

Always follow the abstract guidelines by the journal you are wishing to publish in. That being said, these are some general requirements for writing abstracts:

• An abstract is a summary of the research or article.  Essentially the goal of the abstract is to give a one or two sentence summary from each section  of the article, which typically contains an introduction, methods or design, results, discussion or conclusion. There can be of course deviations from this, but this is typical
• abstracts are in paragraph form. However, some journals have specific formats, one example is below.
• The norm is for 200-250 words for the abstract. Be concise.

What are the keywords for? They are used for indexing and abstracting of your articles, i.e., they help people searching in databases to be able to find your article.

What should I use for keywords? Basically you want to use words that collectively describe your research. They should summarize what your article is about. Look at some publications in your research area and see how they write their keywords. Really think about what the keywords in that particular research are describing or trying to focus on. 

What is the format for keywords? Always follow the journal guidelines that you are publishing in. Most likely they will have specifics. Following APA 7th edition guidelines, the phrase Keywords is to be in italics with a colon, followed by the keywords or phrases separated by commas. After the last keyword, no punctuation is used.   

So if I were writing keywords for this research guide I might use:

Keywords: library research guides, LibGuides, APA 7th edition, citation styles

In this study, we questioned how high school dress codes outlined in official handbooks were written or presented in regard to the gender binary, either/or perspective. We critically analyzed how or if they allowed for flexibility in expression of gender and sexual identity and if they supported, encouraged, or affirmed a variety of expressions, in particular transgender and gender non-conforming expressions, throughout the text or images. The content analysis method was used to analyze 735 handbooks from the 2016 to 2017 school year. Three themes emerged from the data: (1) support of fluid gender expression, yet not overt support; (2) passive marginalization of gender non-conforming or transgender identities or expressions; and (3) active marginalization of gender non-conforming or transgender identities or expressions. The “LGBTQ+ Dress Code Analysis Tool” was developed for policy makers to use to analyze their dress codes.

Keywords : Dress code, gender, high school, LGBTQ+, queer, sexuality

APA abstract: an overview of APA abstract formatting

A professional writer with ten years of experience and a Ph.D. in Modern History, Catharine Tawil writes engaging and insightful papers for academic exchange. With deep insight into the impact of historical events on the present, she provides a unique perspective in giving students a feel for the past. Her writing educates and stimulates critical thinking, making her a treasure to those wading through the complexities of history.

In addition to providing the audience with a brief overview of key points discussed in the article, the APA abstract can also aid in an efficient literature search, offering a glimpse into the paper’s findings and objectives. Apart from highlighting the most vital points of the research, the importance of an APA abstract lies in the following factors:

• Overview convenience. An APA abstract is always concise, meaning that readers will not have to skim over the entire length of the text to understand the point. According to writing professionals who specialize in the field of APA abstracts and academic writing, having an abstract that is too vague or does not adhere to the word count established by formatting guidelines will damage your reputation as a scholar and discourage the audience from giving more attention to your research. 
• Paper relevance. The purpose of an APA abstract page is to convince readers that the paper holds relevance in terms of its academic contribution. The audience that is just getting acquainted with key concepts of your abstract should understand its value and its most pressing challenges and objectives. Otherwise, researchers will be unable to hold the attention of the audience for a long time and will be swiftly overshadowed by other scholars and their work. 
• Efficiency evaluation. Critics can assess the paper by taking a look at its brief deconstruction and thus decide whether it is worth studying further. Researchers should not make the mistake of believing that their work is outstanding by default, immediately setting them apart from other academic professionals. On the contrary, it is critics who will decide whether their research holds any weight and should see the light of the day in terms of publication and online promotion.
• First impression. The abstract in APA allows the audience to analyze the paper’s content and judge its applicability and relevance at first glance. Although stating that first impressions matter may be an age-old adage that holds no relevance, your research will be judged by your APA abstract. Unless you are willing to get your audience hooked from the first minute, you will be forced to give way to more talented researchers who know how to make their abstracts stand out.

The definition of abstract in APA

What is an abstract in APA? An abstract written in APA style can be defined as a brief summary of the main points of the research paper. The abstract in APA is written according to the guidelines of the APA format and should always include key research questions, problems, methods, solutions, and findings. There are a few reasons the APA abstract is held in such high regard and considered an important part of the research process:

• The abstract in APA provides a concise explanation of the research.
• The abstract in APA outlines the key findings and problems of the research.
• The APA abstract allows readers to get an idea of what the paper is going to be about.
• The purpose of the APA abstract lies in providing a comprehensive summation of the paper’s central points. 

An abstract in APA also initiates the contact between the reader and the researcher, impacting the reader’s decision to give their full attention to the text. An APA abstract should also have the following characteristics to be considered complete:

• Briefness. Ideally, an abstract should never be more than 150-250 words to relay a brief and succinct summary of the words without overwhelming the reader with terms and definitions.
• Structure. General guidelines suggest that the abstract in APA should be written in a single block paragraph without indentation, which matches the APA guidelines.
• Components. The abstract should contain separate segments that inform readers about the research problems, methods, results, and conclusion.
• Perspective. A perfect APA abstract will be written in the third person. Researchers need to avoid using the first person when describing their findings.
• Tone. A strictly formal tone should be maintained throughout the paper. Researchers have to make sure that the tone matches the theme of the scholarly work. 
• Keywords. More often than not, the relevant keywords will be listed at the end of the abstract to improve searchability and make it easier for the audience to find the information they need.

Writing an APA abstract: instructions

How to create an abstract in APA that will make a good first impression on the audience and encourage them to give your research paper a look? There is a specific structure you need to follow to make your abstract sound believable and authentic. You should also remember the purpose of your research and the scope of your study. By clearly stating your objectives at the beginning of the research process, you highlight the significant results of your study and how they contribute to your research field. It is also recommended to avoid the excessive use of jargon and colloquialisms while articulating your points in the APA abstract to ensure the audience gets a clear, coherent picture of what the paper explores. 

Preparing the Abstract

• Understand the purpose. You should always keep in mind that a decent APA abstract is only a preview of what the paper is going to be about. Understanding its purpose will help you choose the key elements of your research to present to readers.
• Review guidelines. Reviewing guidelines is another part of the research process that will help you write an APA abstract that matches the requirements. Here, you will have to search for the basic rules of complying with the APA format, including word count and content structure. 
• Determine the key aspects. Your APA abstract should always contain the research problem, methods, results, and conclusions, which are the primary aspects of scientific research that indicate you have conducted substantial preliminary work prior to writing an abstract.
• Read the paper. The researcher’s first obligation when writing an abstract APA is to reread the entire research paper to ensure they know the purpose of abstract writing and can fully disclose the information to readers.

Writing the abstract

• Start with the problem. Use brief terms to provide an outline of your problem, allowing the audience to resonate with the main issue of the research.
• Provide the methods. Highlight the design of your research, listing the number of participants and the procedures you are going to carry out in the process.
• Introduce the results. Your audience will be waiting for the outcome of your research, so don’t hesitate to provide them with the findings and conclusions you have reached during your academic examination.
• Present the implications. Presenting the implications is the process of emphasizing the significance of your research through general conclusions and assumptions drawn from the research process.
• Keep it brief. The main rule of writing an abstract is keeping it brief and adhering to the main rules of word count stated in the APA guidelines. A perfect APA abstract should not be longer than 250 words if the APA guidelines are anything to go by. 
• Avoid complex terms. Each sentence in your abstract should stand as a separate piece of writing and remain easy to understand. It is recommended that the complex terms and definitions be presented in layman’s terms so the audience will not be forced to search for the explanation of specific terms and phrases while reading.

If you have already lost hope that you can create an APA abstract that matches the guidelines and fits the formatting requirements, you can always send a call to write my essay for me and request professional help from a writer who will organize your task.

Structuring the abstract

What is an abstract in APA if it is not properly structured? To make sure your abstract is always perfectly arranged and fits the norms of APA formatting, you can stick to the simple scheme below:

• Title. Start with positioning the word ABSTRACT in the center of the page. 
• Single paragraph. The abstract should be written as a single paragraph with no indentation.
• Introduction. Your introduction is the best way to introduce your research and its main problems. Make sure your introduction is not too long or drawn out (1-2 sentences are enough to illustrate the problem).
• Methods. Describe the methods you are going to use in your research, along with the number of participants and the necessary procedures that will make a part of the research process. Do not write more than 3-4 sentences.
• Results. Here, researchers are required to summarize the key findings in no more than 3-4 sentences, reiterating previous points.
• Conclusion. By stating the main implications of the study, you remind readers about the importance of your research.
• Keywords. An abstract in APA will feature a list of keywords in italics, preceded by the word KEYWORDS at the center of the page.

How to format an APA abstract

An APA abstract can be a challenge to write. It ties in with the fact that you will have to study specific guidelines for APA formatting, as well as know the research paper setup, to be able to structure your paper successfully. Thankfully, there are a few tried and tested strategies that can help you format the abstract with relative ease:

• You should center the word ABSTRACT at the top of the page. The word should not be written in bold or italicized. Do not underline the word or write it in cursive.
• The abstract should present a single double-spaced paragraph. The first line of the abstract should not be indented, and the total word count should never exceed 150-250 words.
• Only standard fonts are used for an APA format abstract. You may choose Times New Roman, Calibri, or Arial for your paper.
• Researchers have to make sure that the page number is included in the header and aligned to the right. 
• The content structure of the APA abstract has to include an introduction, methods, results, and a conclusion that summarizes your key findings.

Keywords in an APA abstract can help your research paper to make a frequent appearance in databases, which also means that your research will be easily found and identified. In addition, having relevant keywords added to your abstract will provide insight into the key aspects of your research. If you want to help academic institutions find your work, you should always place keywords at the end of the abstract on a new line. Keywords are not a part of the main word count, so they should always follow the main text of the abstract.

How to create an abstract in APA, introducing readers to the main ideas of the paper? Researchers should always start by identifying the main concepts of your abstract and choosing the relevant keywords that would improve your paper’s visibility in online databases. 

What is the purpose of an abstract in APA format?

How to write an APA abstract, and what is its purpose? You can think of the APA abstract as the summary of the paper, which helps readers get acquainted with the paper’s content and main ideas without having to read all of the text. This also simplifies the task for critics who analyze your paper and assess its value based on its findings and outcome. They will have a foundation for their assessment in the form of an APA abstract that they can use as a pillar upon which the entire research is standing.

How do I write an APA abstract?

Your APA abstract should always be concise. It is advisable to stick to a word count of 250 words or fewer. Introduce the main ideas of the paper, but do not provide extensive commentary or evaluate the ideas in the abstract. Follow the content structure commonly accepted for the APA abstract, which includes an introduction, methods, results, and conclusion.

What are the key characteristics of an APA abstract?

The main features of an APA abstract are the running header, the section label, the main content of the abstract, all double-spaced and written in a single block, as well as the list of keywords introduced with the word KEYWORDS.

How do I include keywords in an APA abstract?

You should always include relevant keywords in an APA abstract format, choosing no more than 3-5 words per abstract. The word KEYWORDS should be followed by a colon, with the keywords or phrases separated by commas. Make sure that all the keywords used in the APA abstract reflect the main ideas of the research and do not distract readers from the key concepts of your paper. Do not overwhelm the audience with 10 or more unnecessary keyword combinations - having a maximum of 5 keywords that reflect the nature of your text is enough to make an impression and categorize your paper.

What is the difference between an APA abstract and an abstract in other formats?

While an APA abstract is always required for an APA-style paper, MLA-formatted papers do not need an abstract at all. APA abstract is more informative than other formats, presenting readers with many arguments and cases to prove that the text is of relevance. In addition, APA abstracts are always strictly sectioned, unlike so many abstracts in other formats that you can find online. You are required to follow a specific APA structure with purpose, method, results, and conclusion. Abstracts in other formats do not always follow a specific word count, whereas an APA abstract should be compact and succinct.

Title, Abstract and Keywords

The importance of titles.

The title of your manuscript is usually the first introduction readers (and reviewers) have to your work. Therefore, you must select a title that grabs attention, accurately describes the contents of your manuscript, and makes people want to read further.

An effective title should:

• Convey the  main topics  of the study
• Highlight the  importance  of the research
• Be  concise
• Attract  readers

Writing a good title for your manuscript can be challenging. First, list the topics covered by the manuscript. Try to put all of the topics together in the title using as few words as possible. A title that is too long will seem clumsy, annoy readers, and probably not meet journal requirements.

Does Vaccinating Children and Adolescents with Inactivated Influenza Virus Inhibit the Spread of Influenza in Unimmunized Residents of Rural Communities?

This title has too many unnecessary words.

Influenza Vaccination of Children: A Randomized Trial

This title doesn’t give enough information about what makes the manuscript interesting.

Effect of Child Influenza Vaccination on Infection Rates in Rural Communities: A Randomized Trial This is an effective title. It is short, easy to understand, and conveys the important aspects of the research.

Think about why your research will be of interest to other scientists. This should be related to the reason you decided to study the topic. If your title makes this clear, it will likely attract more readers to your manuscript. TIP: Write down a few possible titles, and then select the best to refine further. Ask your colleagues their opinion. Spending the time needed to do this will result in a better title.

Abstract and Keywords

The Abstract is:

• A  summary  of the content of the journal manuscript
• A time-saving  shortcut  for busy researchers
• A guide to the most important parts of your manuscript’s written content

Many readers will only read the Abstract of your manuscript. Therefore, it has to be able to  stand alone . In most cases the abstract is the only part of your article that appears in indexing databases such as Web of Science or PubMed and so will be the most accessed part of your article; making a good impression will encourage researchers to read your full paper.

A well written abstract can also help speed up the peer-review process. During peer review, referees are usually only sent the abstract when invited to review the paper. Therefore, the abstract needs to contain enough information about the paper to allow referees to make a judgement as to whether they have enough expertise to review the paper and be engaging enough for them to want to review it.

Your Abstract should answer these questions about your manuscript:

• What was done?
• Why did you do it?
• What did you find?
• Why are these findings useful and important?

Answering these questions lets readers know the most important points about your study, and helps them decide whether they want to read the rest of the paper. Make sure you follow the proper journal manuscript formatting guidelines when preparing your abstract.

TIP: Journals often set a maximum word count for Abstracts, often 250 words, and no citations. This is to ensure that the full Abstract appears in indexing services.

Keywords  are a tool to help indexers and search engines find relevant papers. If database search engines can find your journal manuscript, readers will be able to find it too. This will increase the number of people reading your manuscript, and likely lead to more citations.

However, to be effective, Keywords must be chosen carefully. They should:

• Represent  the content of your manuscript
• Be  specific  to your field or sub-field

Manuscript title:  Direct observation of nonlinear optics in an isolated carbon nanotube

Poor keywords:  molecule, optics, lasers, energy lifetime

Better keywords:  single-molecule interaction, Kerr effect, carbon nanotubes, energy level structure

Manuscript title:  Region-specific neuronal degeneration after okadaic acid administration Poor keywords:  neuron, brain, OA (an abbreviation), regional-specific neuronal degeneration, signaling

Better keywords:  neurodegenerative diseases; CA1 region, hippocampal; okadaic acid; neurotoxins; MAP kinase signaling system; cell death

Manuscript title:  Increases in levels of sediment transport at former glacial-interglacial transitions

Poor keywords:  climate change, erosion, plant effects Better keywords:  quaternary climate change, soil erosion, bioturbation

🤔 Why Use Online Abstract Generator?

Having trouble writing an abstract? You’re not alone.

Crafting an abstract can be problematic, especially when dealing with voluminous work. After all, converting a 100-page academic paper into 150 words is not an easy task. And this is where an abstract maker can help you immensely.

The amount of time you’ll save by relying on a machine to do the work for you is huge. Not to mention the result will be entirely error-free. No logical, grammatical, or other mistakes will spoil your piece.

Sounds interesting? Then, keep reading to learn more about abstracts and our generator.

An abstract is a brief summary of a work. Usually, it's a single paragraph containing 150 to 250 words. It describes all the key points and elements of an article, essay, or work of any other format.

Keep in mind that an abstract merely describes a text. It shouldn’t be an evaluation or an attempt to defend the paper. Instead, it’s just an overview.

Structure of an Abstract

An abstract is not a simple summary. It has a specific structure and should contain the following elements:

• The main issue . Describe the problem you are trying to solve with your research.
• The background . Include everything the reader needs to know before delving into your text.
• The goal . Don’t forget to describe the reasons behind your work.
• The methods . Tell the readers how exactly you performed your research.
• The results . What did you discover? If no particular result comes to mind, you can list your arguments here instead.
• The implications . Show the reader how significant your work is.

Remember that an abstract is separate from the rest of the paper. For the reader to get the complete picture of your research, your abstract must include everything listed above.

✍️ How to Write an Abstract

It can be tempting to go and write an abstract right away. But make sure to finish the planning of your work first. You want to write your abstract about your piece's contents, not build the contents around your abstract.

To make the writing process easier, divide it into 5 manageable steps:

• Check the requirements. First off, you need to know how much you are allowed to write. An average abstract is about 150-250 words long, but there is often a strict limit. Make sure to stay within it!
• Establish the goal and the problems of the research. The reader needs to know what your paper will be about right from the get-go. That’s why you need to formulate your thesis and showcase it first.
• Establish the methods. Tell the reader how you did your research. Don’t go in too deep: simply describe the methods without unnecessary details.
• Describe the results. Write a couple of sentences about the outcome of your investigation.
• Write a conclusion. Address the issue you established in the second step. You might also want to mention your work’s limitations regarding your research samples or methods. Try to give the reader a clear understanding of your goal and how you achieved it.

Want to make the process even easier? Use our abstract tool! Online generators like ours will help you craft an excellent paragraph in a matter of seconds.

As an example, check out this abstract of the article “Bioeffcacy of Mentha piperita essential oil against dengue fever mosquito” by Sarita Kumar:

The Mentha balsamea, or peppermint plant, is a result of cross-breeding between spearmint and water mint. These plants are most commonly used in the area of repelling insects. The following research revolves around peppermint oil insect repellent and its development. As a part of an experiment, we obtained 25 grams of fresh peppermint and, after grinding it, put it in a glass jar with olive oil. The jar was then left for two days in a warm temperate. Next, the oil was strained with a cheesecloth, gathered, and diluted at 70%. It then got separated into three different spray bottles. The test was to put the spray sample into a jar with mosquitoes and equate the result to the same test with a commercial repellant. Thus, we challenged the stereotype of synthetic repellents being more efficient than their analogs made from natural materials.

New York Times editorial board calls Donald Trump 'unfit to lead,' urges voters to reject reelection bid

WASHINGTON - The New York Times' editorial boar d called on voters to reject Donald Trump' s reelection bid, alleging that the former president is "unfit to lead" a second term. 

“Mr. Trump has shown a character unworthy of the responsibilities of the presidency. He has demonstrated an utter lack of respect for the Constitution, the rule of law and the American people,” wrote the Times editorial board, made up of opinion journalists, in a piece published Thursday.

“Instead of a cogent vision for the country’s future, Mr. Trump is animated by a thirst for political power: to use the levers of government to advance his interests, satisfy his impulses and exact retribution against those who he thinks have wronged him,” they added. 

In the piece, the editorial board outlined five “essential” qualities and values that they feel a president must have - and that they say Trump fails on: moral fitness, principled leadership, character, a president’s words and rule of law.

“We urge voters to see the dangers of a second Trump term clearly and to reject it,” they wrote. 

Last month, the New York Times editorial board published a piece calling on President Joe Biden to drop out of the 2024 race following a disastrous debate performance. The president struggled to complete sentences during the showdown and articulate his pitch to voters.

The Times argued in its op-ed piece at the time that "the president is engaged in a reckless gamble," adding that "it's too big a bet to simply hope Americans will overlook or discount Mr. Biden's age and infirmity that they see with their own eyes."

Since the debate, a growing handful of Democratic lawmakers have called on Biden to pass the torch and exit the 2024 race for the White House.

Rep. Hillary Scholten, D-Mich., on Thursday became the 10th House member to publicly call for Biden to leave the presidential race, adding to the drip of lawmakers pushing for change.

He is dangerous in word, deed and action

He puts self over country, he loathes the laws we live by, donald trump is unfit to lead.

The editorial board is a group of opinion journalists whose views are informed by expertise, research, debate and certain longstanding values . It is separate from the newsroom.

Next week, for the third time in eight years, Donald Trump will be nominated as the Republican Party’s candidate for president of the United States. A once great political party now serves the interests of one man, a man as demonstrably unsuited for the office of president as any to run in the long history of the Republic, a man whose values, temperament, ideas and language are directly opposed to so much of what has made this country great.

It is a chilling choice against this national moment. For more than two decades, large majorities of Americans have said they are dissatisfied with the direction of the country, and the post-Covid era of stubborn inflation, high interest rates, social division and political stagnation has left many voters even more frustrated and despondent.

The Republican Party once pursued electoral power in service to solutions for such problems, to building “the shining city on a hill,” as Ronald Reagan liked to say. Its vision of the United States — embodied in principled public servants like George H.W. Bush, John McCain and Mitt Romney — was rooted in the values of freedom, sacrifice, individual responsibility and the common good. The party’s conception of those values was reflected in its longstanding conservative policy agenda, and today many Republicans set aside their concerns about Mr. Trump because of his positions on immigration, trade and taxes. But the stakes of this election are not fundamentally about policy disagreements. The stakes are more foundational: what qualities matter most in America’s president and commander in chief.

Mr. Trump has shown a character unworthy of the responsibilities of the presidency. He has demonstrated an utter lack of respect for the Constitution, the rule of law and the American people. Instead of a cogent vision for the country’s future, Mr. Trump is animated by a thirst for political power: to use the levers of government to advance his interests, satisfy his impulses and exact retribution against those who he thinks have wronged him.

He is, quite simply, unfit to lead.

The Democrats are rightly engaged in their own debate about whether President Biden is the right person to carry the party’s nomination into the election, given widespread concerns among voters about his age-related fitness. This debate is so intense because of legitimate concerns that Mr. Trump may present a danger to the country, its strength, security and national character — and that a compelling Democratic alternative is the only thing that would prevent his return to power. It is a national tragedy that the Republicans have failed to have a similar debate about the manifest moral and temperamental unfitness of their standard-bearer, instead setting aside their longstanding values, closing ranks and choosing to overlook what those who worked most closely with the former president have described as his systematic dishonesty, corruption, cruelty and incompetence.

That task now falls to the American people. We urge voters to see the dangers of a second Trump term clearly and to reject it. The stakes and significance of the presidency demand a person who has essential qualities and values to earn our trust, and on each one, Donald Trump fails.

Moral Fitness Matters

Presidents are confronted daily with challenges that require not just strength and conviction but also honesty, humility, selflessness, fortitude and the perspective that comes from sound moral judgment.

If Mr. Trump has these qualities, Americans have never seen them in action on behalf of the nation’s interests. His words and actions demonstrate a disregard for basic right and wrong and a clear lack of moral fitness for the responsibilities of the presidency.

He lies blatantly and maliciously, embraces racists , abuses women and has a schoolyard bully’s instinct to target society’s most vulnerable. He has delighted in coarsening and polarizing the town square with ever more divisive and incendiary language. Mr. Trump is a man who craves validation and vindication, so much that he would prefer a hostile leader’s lies to his own intelligence agencies’ truths and would shake down a vulnerable ally for short-term political advantage . His handling of everything from routine affairs to major crises was undermined by his blundering combination of impulsiveness, insecurity and unstudied certainty.

This record shows what can happen to a country led by such a person: America’s image, credibility and cohesion were relentlessly undermined by Mr. Trump during his term.

None of his wrongful actions are so obviously discrediting as his determined and systematic attempts to undermine the integrity of elections — the most basic element of any democracy — an effort that culminated in an insurrection at the Capitol to obstruct the peaceful transfer of power.

On Jan. 6, 2021, Mr. Trump incited a mob to violence with hateful lies, then stood by for hours as hundreds of his supporters took his word and stormed the Capitol with the aim of terrorizing members of Congress into keeping him in office. He praised these insurrectionists and called them patriots; today he gives them a starring role at campaign rallies, playing a rendition of the national anthem sung by inmates involved with Jan. 6., and he has promised to consider pardoning the rioters if re-elected. He continues to wrong the country and its voters by lying about the 2020 election, branding it stolen, despite the courts, the Justice Department and Republican state officials disputing him. No man fit for the presidency would flog such pernicious and destructive lies about democratic norms and values, but the Trumpian hunger for vindication and retribution has no moral center.

To vest such a person with the vast powers of the presidency is to endanger American interests and security at home as well as abroad. The nation’s commander in chief must uphold the oath to “preserve, protect and defend the Constitution.” It is the closest thing that this secular nation has to a sacred trust. The president has several duties and powers that are his alone: He has the sole authority to launch a nuclear weapon. He has the authority to send American troops into harm’s way and to authorize the use of lethal force against individuals and other nations. Americans who serve in the military also take an oath to defend the Constitution, and they rely on their commander in chief to take that oath as seriously as they do.

Mr. Trump has shown, repeatedly, that he does not. On numerous occasions, he asked his defense secretary and commanders in the American armed forces to violate that oath. On other occasions, he demanded that members of the military violate norms that preserve the dignity of the armed services and protect the military from being used for political purposes. They largely refused these illegal and immoral orders, as the oath requires.

The lack of moral grounding undermines Mr. Trump even in areas where voters view him as stronger and trust him more than Mr. Biden, like immigration and crime. Veering into a kind of brutal excess that is, at best, immoral and, at worst, unconstitutional, he has said that undocumented immigrants were “ poisoning the blood of our country ,” and his advisers say he would aim to round them up in mass detention camps and end birthright citizenship . He has indicated that, if faced with episodes of rioting or crime surges, he would unilaterally send troops into American cities. He has asked aides if the United States could shoot migrants below the waist to slow them down, and he has said that he would use the Insurrection Act to deploy the military against protesters.

During his time in office, none of those things happened because there were enough people in military leadership with the moral fitness to say “no” to such illegal orders. But there are good reasons to worry about whether that would happen again, as Mr. Trump works harder to surround himself with people who enable rather than check his most insidious impulses.

The Supreme Court, with its ruling on July 1 granting presidents “absolute immunity” for official acts, has removed an obstacle to Mr. Trump’s worst impulses: the threat of legal consequences. What remains is his own sense of right and wrong. Our country’s future is too precious to rely on such a broken moral compass.

Principled Leadership Matters

Republican presidents and presidential candidates have used their leadership at critical moments to set a tone for society to live up to. Mr. Reagan faced down totalitarianism in the 1980s, appointed the first woman to the Supreme Court and worked with Democrats on bipartisan tax and immigration reforms. George H.W. Bush signed the Americans With Disabilities Act and decisively defended an ally, Kuwait, against Iraqi aggression. George W. Bush, for all his failures after Sept. 11, did not stoke hate against or demonize Muslims or Islam.

As a candidate during the 2008 race, Mr. McCain spoke out when his fellow conservatives spread lies about his opponent, Barack Obama. Mr. Romney was willing to sacrifice his standing and influence in the party he once represented as a presidential nominee, by boldly calling out Mr. Trump’s failings and voting for his removal from office.

These acts of leadership are what it means to put country first, to think beyond oneself.

Mr. Trump has demonstrated contempt for these American ideals. He admires autocrats, from Viktor Orban to Vladimir Putin to Kim Jong-un. He believes in the strongman model of power — a leader who makes things happen by demanding it, compelling agreement through force of will or personality. In reality, a strongman rules through fear and the unprincipled use of political might for self-serving ends, imposing poorly conceived policies that smother innovation, entrepreneurship, ideas and hope.

During his four years in office, Mr. Trump tried to govern the United States as a strongman would, issuing orders or making decrees on Twitter. He announced sudden changes in policy — on who can serve in the military , on trade policy, on how the United States deals with North Korea or Russia — without consulting experts on his staff about how these changes would affect America. Indeed, nowhere did he put his political or personal interests above the national interest more tragically than during the pandemic , when he faked his way through a crisis by touting conspiracy theories and pseudoscience while ignoring the advice of his own experts and resisting basic safety measures that would have saved lives.

He took a similar approach to America’s strategic relationships abroad. Mr. Trump lost the trust of America’s longstanding allies, especially in NATO, leaving Europe less secure and emboldening the far right and authoritarian leaders in Europe, Latin America and Asia. He pulled out of the Iran nuclear deal, leaving that country, already a threat to the world, more dangerous, thanks to a revived program that has achieved near-weapons-grade uranium.

In a second term, his willingness to appease Mr. Putin would leave Ukraine’s future as a democratic and independent country in doubt. Mr. Trump implies that he could single-handedly end the catastrophic war in Gaza but has no real plan. He has suggested that in a second term he’d increase tariffs on Chinese goods to 60 percent or higher and that he would put a 10 percent tariff on all imported goods, moves that would raise prices for American consumers and reduce innovation by allowing U.S. industries to rely on protectionism instead.

The worst of the Trump administration’s policies were often blocked by Congress, by court challenges and by the objections of honorable public servants who stepped in to thwart his demands when they were irresponsible or did not follow the law. When Mr. Trump wanted an end to Obamacare, a single Republican senator, Mr. McCain, saved it, preserving health care for millions of Americans. Mr. Trump demanded that James Comey, his F.B.I. director, pledge loyalty to him and end an investigation into a political ally; Mr. Comey refused. Scientists and public health officials called out and corrected his misinformation about climate science and Covid. The Supreme Court sided against the Trump administration more times than any other president since at least Franklin D. Roosevelt.

A second Trump administration would be different. He intends to fill his administration with sycophants, those who have shown themselves willing to obey Mr. Trump’s demands or those who lack the strength to stand up to him. He wants to remove those who would be obstacles to his agenda, by enacting an order to make it easier to fire civil servants and replace them with those more loyal to him.

This means not only that Americans would lose the benefit of their expertise but also that America would be governed in a climate of fear, in which government employees must serve the interests of the president rather than the public. All cabinet secretaries follow a president’s lead, but Mr. Trump envisions a nation in which public service as Americans understand it would cease to exist — where individual civil servants and departments could no longer make independent decisions and where research by scientists and public health experts and investigations by the Justice Department and others in federal law enforcement would be more malleable to the demands of the White House.

Another term under Mr. Trump’s leadership would risk doing permanent damage to our government. As Mr. Comey, a longtime Republican, wrote in a 2019 guest essay for Times Opinion, “Accomplished people lacking inner strength can’t resist the compromises necessary to survive Mr. Trump and that adds up to something they will never recover from.” Very few who serve under him can avoid this fate “because Mr. Trump eats your soul in small bites,” Mr. Comey wrote. “Of course, to stay, you must be seen as on his team, so you make further compromises. You use his language, praise his leadership, tout his commitment to values. And then you are lost. He has eaten your soul.” America will get nowhere with a strongman. It needs a strong leader.

Character Matters

Character is the quality that gives a leader credibility, authority and influence. During the 2016 campaign, Mr. Trump’s petty attacks on his opponents and their families led many Republicans to conclude that he lacked such character. Other Republicans, including those who supported the former president’s policies in office, say they can no longer in good conscience back him for the presidency. “It’s a job that requires the kind of character he just doesn’t have,” Paul Ryan, a former Republican House speaker, said of Mr. Trump in May .

Those who know Mr. Trump’s character best — the people he appointed to serve in the most important positions of his White House — have expressed grave doubts about his fitness for office.

His former chief of staff John Kelly, a retired four-star Marine Corps general, described Mr. Trump as “a person who admires autocrats and murderous dictators. A person that has nothing but contempt for our democratic institutions, our Constitution and the rule of law.” Bill Barr, whom Mr. Trump appointed as attorney general, said of him , “He will always put his own interest and gratifying his own ego ahead of everything else, including the country’s interest.” James Mattis, a retired four-star Marine general who served as defense secretary, said , “Donald Trump is the first president in my lifetime who does not try to unite the American people — does not even pretend to try.”

Mike Pence, Mr. Trump’s vice president, has disavowed him. No other vice president in modern American history has done this. “I believe that anyone who puts themselves over the Constitution should never be president of the United States,” Mr. Pence has said . “And anyone who asked someone else to put them over the Constitution should never be president of the United States again.”

These are hardly exceptions. In any other American administration, a single cabinet-level defection is rare. But an unprecedented number of Mr. Trump’s appointees have publicly criticized his leadership, opposed his 2024 presidential candidacy or ducked questions about his fitness for a second term. More than a dozen of his most senior appointees — those he chose to work alongside him and who saw his performance most closely — have spoken out against him, serving as witnesses about the kind of leader he is.

There are many ways to judge leaders’ character; one is to see whether they accept responsibility for their actions. As a general rule, Mr. Trump abhors accountability. If he loses, the election is rigged. If he is convicted, it’s because the judges are out to get him. If he doesn’t get his way in a deal, as happened multiple times with Congress in his term, he shuts down the government or threatens to.

Americans do not expect their presidents to be perfect; many of them have exhibited hubris, self-regard, arrogance and other character flaws. But the American system of government is more than just the president: It is a system of checks and balances, and it relies on everyone in government to intervene when a president’s personal failings might threaten the common good.

Mr. Trump tested those limits as president, and little has changed about him in the four years since he lost re-election. He tries to intimidate anyone with the temerity to testify as a witness against him. He attacks the integrity of judges who are doing their duty to hold him accountable to the law. He mocks those he dislikes and lies about those who oppose him and targets Republicans for defeat if they fail to bend the knee.

It may be tempting for Americans to believe that a second Trump presidency would be much like the first, with the rest of government steeled to protect the country and resist his worst impulses. But the strongman needs others to be weak, and Mr. Trump is surrounding himself with yes men.

The American public has a right to demand more from their president and those who would serve under him.

A President’s Words Matter

When America saw white nationalists and neo-Nazis march through the streets of Charlottesville, Va., in 2017 and activists were rallying against racism, Mr. Trump spoke of “very fine people on both sides.” When he was pressed about the white supremacist Proud Boys during a 2020 debate, Mr. Trump told them to “stand back and stand by,” a request that, records show, they took literally in deciding to storm Congress. This winter, the former president urged Iowans to vote for him and score a victory over their fellow Americans — “all of the liars, cheaters, thugs, perverts, frauds, crooks, freaks, creeps.” And in a Veterans Day speech in New Hampshire, he used the word “vermin,” a term he has deployed to describe both immigrants and political opponents.

What a president says reflects on the United States and the kind of society we aspire to be.

In 2022 this board raised an urgent alarm about the rising threat of political violence in the United States and what Americans could do to stop it. At the time, Mr. Trump was preparing to declare his intention to run for president again, and the Republican Party was in the middle of a fight for control, between Trumpists and those who were ready to move on from his destructive leadership. This struggle within the party has consequences for all Americans. “A healthy democracy requires both political parties to be fully committed to the rule of law and not to entertain or even tacitly encourage violence or violent speech,” we wrote.

A large faction of one party in our country fails that test, and that faction, Mr. Trump’s MAGA extremists, now control the party and its levers of power. There are many reasons his conquest of the Republican Party is bad for American democracy, but one of the most significant is that those extremists have often embraced violent speech or the belief in using violence to achieve their political goals. This belief led to the Jan. 6 attack on the Capitol, and it has resulted in a rising number of threats against judges, elected officials and prosecutors.

This threat cannot be separated from Mr. Trump’s use of language to encourage violence, to dehumanize groups of people and to spread lies. A study by researchers at the University of California, Davis, released in October 2022, came to the conclusion that MAGA Republicans (as opposed to those who identified themselves as traditional Republicans) “are more likely to hold extreme and racist beliefs, to endorse political violence, to see such violence as likely to occur and to predict that they will be armed under circumstances in which they consider political violence to be justified.”

The Republican Party had an opportunity to renounce Trumpism; it has submitted to it. Republican leaders have had many opportunities to repudiate his violent discourse and make clear that it should have no place in political life; they failed to. Sizable numbers of voters in Republican primaries abandoned Mr. Trump for other candidates, and independent and undecided voters have said that Mr. Trump’s language has alienated them from his candidacy.

But with his nomination by his party all but assured, Mr. Trump has become even more reckless in employing extreme and violent speech, such as his references to executing generals who raise questions about his actions. He has argued, before the Supreme Court, that he should have the right to assassinate a political rival and face no consequences.

The Rule of Law Matters

The danger from these foundational failings — of morals and character, of principled leadership and rhetorical excess — is never clearer than in Mr. Trump’s disregard for rule of law, his willingness to do long-term damage to the integrity of America’s systems for short-term personal gain.

As we’ve noted, Mr. Trump’s disregard for democracy was most evident in his attempts to overturn the results of the 2020 election and to encourage violence to stop the peaceful transfer of power. What stood in his way were the many patriotic Americans, at every level of government, who rejected his efforts to bully them into complying with his demands to change election results. Instead, they followed the rules and followed the law. This respect for the rule of law, not the rule of men, is what has allowed American democracy to survive for more than 200 years.

In the four years since losing the election, Mr. Trump has become only more determined to subvert the rule of law, because his whole theory of Trumpism boils down to doing whatever he wants without consequence. Americans are seeing this unfold as Mr. Trump attempts to fight off numerous criminal charges. Not content to work within the law to defend himself, he is instead turning to sympathetic judges — including two Supreme Court justices with apparent conflicts over the 2020 election and Jan. 6-related litigation. The playbook: delay federal prosecution until he can win election and end those legal cases. His vision of government is one that does what he wants, rather than a government that operates according to the rule of law as prescribed by the Constitution, the courts and Congress.

As divided as America is, people across the political spectrum generally recoil from rigged rules, favoritism, self-dealing and abuse of power. Our country has been so stable for so long in part because most Americans and most American leaders follow the rules or face the consequences.

So much in the past two decades has tested these norms in our society — the invasion of Iraq under false pretenses, the failures that led to the 2008 financial crisis and the recession that followed, the pandemic and all the fractures and inequities that it revealed. We need a recommitment to the rule of law and the values of fair play. This election is a moment for Americans to decide whether we will keep striving for those ideals.

Mr. Trump rejects them. If he is re-elected, America will face a new and precarious future, one that it may not be prepared for. It is a future in which intelligence agencies would be judged not according to whether they preserved national security but by whether they served Mr. Trump’s political agenda. It means that prosecutors and law enforcement officials would be judged not according to whether they follow the law to keep Americans safe but by whether they obey his demands to “go after” political enemies. It means that public servants would be judged not according to their dedication or skill but by whether they show sufficient loyalty to him and his MAGA agenda.

Even if Mr. Trump’s vague policy agenda would not be fulfilled, he could rule by fear. The lesson of other countries shows that when a bureaucracy is politicized or pressured, the best public servants will run for the exits.

This is what has already happened in Mr. Trump’s Republican Party, with principled leaders and officials retiring, quitting or facing ouster. In a second term, he intends to do that to the whole of government.

Election Day is less than four months away. The case against Mr. Trump is extensive, and this board urges Americans to perform a simple act of civic duty in an election year: Listen to what Mr. Trump is saying, pay attention to what he did as president and allow yourself to truly inhabit what he has promised to do if returned to office.

Voters frustrated by inflation and immigration or attracted by the force of Mr. Trump’s personality should pause and take note of his words and promises. They have little to do with unity and healing and a lot to do with making the divisions and anger in our society wider and more intense than they already are.

The Republican Party is making its choice next week; soon all Americans will be able to make their own choice. What would Mr. Trump do in a second term? He has told Americans who he is and shown them what kind of leader he would be.

When someone fails so many foundational tests, you don’t give him the most important job in the world.

In making the federal sentencing guidelines advisory, Booker v. United States made the influence of those guidelines dependent on their perceived legitimacy. This Article argues that, given the link between law's legitimacy and its democratic character, Booker should be read as a demand for democracy in sentencing. This demand echoes the one imbued in the U.S. Sentencing Commission's statutory charter, which gives the agency unique potential to create administrative governance that is of the people, for the people, and by the people. In detailing past and present efforts to fulfill that potential, this Article invites readers to assist the Commission in its continuing pursuit of more democratic sentencing policy.
