How to Write a Research Paper Introduction (with Examples)

Table of Contents

The research paper introduction section, along with the Title and Abstract, can be considered the face of any research paper. The following article is intended to guide you in organizing and writing the research paper introduction for a quality academic article or dissertation.

The research paper introduction aims to present the topic to the reader. A study will only be accepted for publishing if you can ascertain that the available literature cannot answer your research question. So it is important to ensure that you have read important studies on that particular topic, especially those within the last five to ten years, and that they are properly referenced in this section. 1

What should be included in the research paper introduction is decided by what you want to tell readers about the reason behind the research and how you plan to fill the knowledge gap. The best research paper introduction provides a systemic review of existing work and demonstrates additional work that needs to be done. It needs to be brief, captivating, and well-referenced; a well-drafted research paper introduction will help the researcher win half the battle.

The introduction for a research paper is where you set up your topic and approach for the reader. It has several key goals:

• Present your research topic
• Capture reader interest
• Summarize existing research
• Position your own approach
• Define your specific research problem and problem statement
• Highlight the novelty and contributions of the study
• Give an overview of the paper’s structure

The research paper introduction can vary in size and structure depending on whether your paper presents the results of original empirical research or is a review paper. Some research paper introduction examples are only half a page while others are a few pages long. In many cases, the introduction will be shorter than all of the other sections of your paper; its length depends on the size of your paper as a whole.

What is the introduction for a research paper?

The introduction in a research paper is placed at the beginning to guide the reader from a broad subject area to the specific topic that your research addresses. They present the following information to the reader

• Scope: The topic covered in the research paper
• Context: Background of your topic
• Importance: Why your research matters in that particular area of research and the industry problem that can be targeted

Why is the introduction important in a research paper?

The research paper introduction conveys a lot of information and can be considered an essential roadmap for the rest of your paper. A good introduction for a research paper is important for the following reasons:

• It stimulates your reader’s interest: A good introduction section can make your readers want to read your paper by capturing their interest. It informs the reader what they are going to learn and helps determine if the topic is of interest to them.
• It helps the reader understand the research background: Without a clear introduction, your readers may feel confused and even struggle when reading your paper. A good research paper introduction will prepare them for the in-depth research to come. It provides you the opportunity to engage with the readers and demonstrate your knowledge and authority on the specific topic.
• It explains why your research paper is worth reading: Your introduction can convey a lot of information to your readers. It introduces the topic, why the topic is important, and how you plan to proceed with your research.
• It helps guide the reader through the rest of the paper: The research paper introduction gives the reader a sense of the nature of the information that will support your arguments and the general organization of the paragraphs that will follow.

What are the parts of introduction in the research?

A good research paper introduction section should comprise three main elements: 2

• What is known: This sets the stage for your research. It informs the readers of what is known on the subject.
• What is lacking: This is aimed at justifying the reason for carrying out your research. This could involve investigating a new concept or method or building upon previous research.
• What you aim to do: This part briefly states the objectives of your research and its major contributions. Your detailed hypothesis will also form a part of this section.

How to write a research paper introduction?

The first step in writing the research paper introduction is to inform the reader what your topic is and why it’s interesting or important. This is generally accomplished with a strong opening statement. The second step involves establishing the kinds of research that have been done and ending with limitations or gaps in the research that you intend to address.

Finally, the research paper introduction clarifies how your own research fits in and what problem it addresses. If your research involved testing hypotheses, these should be stated along with your research question. The hypothesis should be presented in the past tense since it will have been tested by the time you are writing the research paper introduction.

The following key points, with examples, can guide you when writing the research paper introduction section:

1. Introduce the research topic:

• Highlight the importance of the research field or topic
• Describe the background of the topic
• Present an overview of current research on the topic

Example: The inclusion of experiential and competency-based learning has benefitted electronics engineering education. Industry partnerships provide an excellent alternative for students wanting to engage in solving real-world challenges. Industry-academia participation has grown in recent years due to the need for skilled engineers with practical training and specialized expertise. However, from the educational perspective, many activities are needed to incorporate sustainable development goals into the university curricula and consolidate learning innovation in universities.

2. Determine a research niche:

• Reveal a gap in existing research or oppose an existing assumption
• Formulate the research question

Example: There have been plausible efforts to integrate educational activities in higher education electronics engineering programs. However, very few studies have considered using educational research methods for performance evaluation of competency-based higher engineering education, with a focus on technical and or transversal skills. To remedy the current need for evaluating competencies in STEM fields and providing sustainable development goals in engineering education, in this study, a comparison was drawn between study groups without and with industry partners.

3. Place your research within the research niche:

• State the purpose of your study
• Highlight the key characteristics of your study
• Describe important results
• Highlight the novelty of the study.
• Offer a brief overview of the structure of the paper.

Example: The study evaluates the main competency needed in the applied electronics course, which is a fundamental core subject for many electronics engineering undergraduate programs. We compared two groups, without and with an industrial partner, that offered real-world projects to solve during the semester. This comparison can help determine significant differences in both groups in terms of developing subject competency and achieving sustainable development goals.

Frequently Asked Questions

What is the purpose of the introduction in research papers.

The purpose of the research paper introduction is to introduce the reader to the problem definition, justify the need for the study, and describe the main theme of the study. The aim is to gain the reader’s attention by providing them with necessary background information and establishing the main purpose and direction of the research.

How long should the research paper introduction be?

The length of the research paper introduction can vary across journals and disciplines. While there are no strict word limits for writing the research paper introduction, an ideal length would be one page, with a maximum of 400 words over 1-4 paragraphs. Generally, it is one of the shorter sections of the paper as the reader is assumed to have at least a reasonable knowledge about the topic. 2

For example, for a study evaluating the role of building design in ensuring fire safety, there is no need to discuss definitions and nature of fire in the introduction; you could start by commenting upon the existing practices for fire safety and how your study will add to the existing knowledge and practice.

What should be included in the research paper introduction?

When deciding what to include in the research paper introduction, the rest of the paper should also be considered. The aim is to introduce the reader smoothly to the topic and facilitate an easy read without much dependency on external sources. 3

Below is a list of elements you can include to prepare a research paper introduction outline and follow it when you are writing the research paper introduction.

• Topic introduction: This can include key definitions and a brief history of the topic.
• Research context and background: Offer the readers some general information and then narrow it down to specific aspects.
• Details of the research you conducted: A brief literature review can be included to support your arguments or line of thought.
• Rationale for the study: This establishes the relevance of your study and establishes its importance.
• Importance of your research: The main contributions are highlighted to help establish the novelty of your study
• Research hypothesis: Introduce your research question and propose an expected outcome. Organization of the paper: Include a short paragraph of 3-4 sentences that highlights your plan for the entire paper

Should I include citations in the introduction for a research paper?

Cite only works that are most relevant to your topic; as a general rule, you can include one to three. Note that readers want to see evidence of original thinking. So it is better to avoid using too many references as it does not leave much room for your personal standpoint to shine through.

Citations in your research paper introduction support the key points, and the number of citations depend on the subject matter and the point discussed. If the research paper introduction is too long or overflowing with citations, it is better to cite a few review articles rather than the individual articles summarized in the review.

A good point to remember when citing research papers in the introduction section is to include at least one-third of the references in the introduction.

Should I provide a literature review in the research paper introduction?

The literature review plays a significant role in the research paper introduction section. A good literature review accomplishes the following:

• Introduces the topic
• Establishes the study’s significance
• Provides an overview of the relevant literature
• Provides context for the study using literature
• Identifies knowledge gaps

However, remember to avoid making the following mistakes when writing a research paper introduction:

• Do not use studies from the literature review to aggressively support your research
• Avoid direct quoting
• Do not allow literature review to be the focus of this section. Instead, the literature review should only aid in setting a foundation for the manuscript. 

Key points to remember

Remember the following key points for writing a good research paper introduction: 4

• Avoid stuffing too much general information: Avoid including what an average reader would know and include only that information related to the problem being addressed in the research paper introduction. For example, when describing a comparative study of non-traditional methods for mechanical design optimization, information related to the traditional methods and differences between traditional and non-traditional methods would not be relevant. In this case, the introduction for the research paper should begin with the state-of-the-art non-traditional methods and methods to evaluate the efficiency of newly developed algorithms.
• Avoid packing too many references: Cite only the required works in your research paper introduction. The other works can be included in the discussion section to strengthen your findings.
• Avoid extensive criticism of previous studies: Avoid being overly critical of earlier studies while setting the rationale for your study. A better place for this would be the Discussion section, where you can highlight the advantages of your method.
• Avoid describing conclusions of the study: When writing a research paper introduction remember not to include the findings of your study. The aim is to let the readers know what question is being answered. The actual answer should only be given in the Results and Discussion section.

To summarize, the research paper introduction section should be brief yet informative. It should convince the reader the need to conduct the study and motivate him to read further. If you’re feeling stuck or unsure, choose trusted AI academic writing assistants like Paperpal to effortlessly craft your research paper introduction and other sections of your research article.

Research Paper Introduction

The introduction of a research paper serves as the first impression and sets the stage for the rest of the study. It provides background information, introduces the research topic, establishes the purpose of the paper, and guides readers toward the research question or thesis statement. A well-crafted introduction helps readers understand the significance of the study and its broader context, making them eager to read further.

Purpose of a Research Paper Introduction

The main purpose of a research paper introduction is to:

• Present the Research Topic : Define the scope and relevance of the topic.
• Provide Background Information : Offer a brief overview of existing research, theories, or key concepts.
• State the Research Problem : Explain the issue or gap in the literature that the study addresses.
• Highlight the Study’s Significance : Convey why the research matters and its potential impact.
• Outline the Research Objectives or Questions : Indicate the specific goals or questions guiding the study.
• Conclude with a Thesis Statement : Summarize the main argument or position the paper will take.

Example : For a research paper on the effects of remote work on employee productivity, the introduction could outline the growing popularity of remote work, discuss previous findings on productivity in traditional office settings, and present a research question exploring the impact of remote work environments.

Key Elements of a Research Paper Introduction

To write an effective introduction, include the following elements:

1. Opening Hook

The opening hook is a compelling sentence that captures the reader’s attention. It could be an interesting fact, statistic, anecdote, or quote that draws readers into the topic.

Example : “In 2020, over 42% of the U.S. workforce transitioned to remote work, a shift that redefined traditional notions of productivity and work-life balance.”

2. Background Information

Provide context by discussing the topic, relevant concepts, and any key studies. This section should briefly address what is already known about the topic and why it matters, setting the stage for your research problem.

Example : “Remote work has been a growing trend in the modern workplace, with numerous studies examining its effects on employee satisfaction, work-life balance, and overall productivity.”

3. Research Problem or Gap

Identify the specific research problem or gap that the study addresses. Highlighting this gap shows readers what remains unexplored or unresolved within the topic.

Example : “While previous research has focused on remote work’s impact on job satisfaction, little is known about how it directly influences productivity metrics compared to traditional office settings.”

4. Purpose and Significance of the Study

Explain why the research is important and how it contributes to existing knowledge. State the potential benefits, applications, or implications of your findings.

Example : “Understanding how remote work impacts productivity can help businesses develop strategies to optimize employee performance in virtual environments.”

5. Research Objectives or Questions

Specify the objectives or main research questions guiding the study. These should be concise and directly related to the research problem.

Example : “This study aims to investigate how remote work environments affect productivity and whether these effects vary across different industries.”

6. Thesis Statement or Hypothesis

Conclude the introduction with a clear thesis statement or hypothesis that reflects the study’s main argument or anticipated findings.

Example : “The paper hypothesizes that remote work positively affects productivity levels among employees, particularly in technology-driven fields.”

Step-by-Step Guide to Writing a Research Paper Introduction

Step 1: start with a hook.

Begin your introduction with a hook that captures the reader’s attention. Use a surprising fact, an intriguing statistic, or a thought-provoking question to set the tone.

Example : “As digital technologies continue to evolve, remote work has become more accessible, transforming the traditional office into a virtual workspace.”

Step 2: Provide Background Information

Build on the hook by offering essential context for the topic. Discuss the main concepts, relevant literature, or trends, and introduce any foundational theories or studies that relate to your research.

Example : “Over the past decade, remote work has become an increasingly popular option, driven by advancements in communication technologies and shifts in work culture.”

Step 3: Define the Research Problem or Gap

Clearly state the research problem, emphasizing the specific gap in the existing literature that your study addresses. This step is critical for justifying your study’s relevance.

Example : “Despite extensive research on employee productivity, few studies have examined the impact of remote work environments compared to traditional office settings.”

Step 4: Explain the Study’s Significance

Describe why the study is important and its potential contributions to the field. Explain how it will advance understanding or provide insights that can inform policy, practice, or further research.

Example : “Understanding productivity in remote work environments is essential for companies that seek to optimize performance in a changing work landscape.”

Step 5: Outline the Research Objectives or Questions

List the main objectives or research questions that the study seeks to address. These should be directly related to the research problem and specify the study’s focus.

Example : “This paper investigates how remote work affects employee productivity and identifies factors that may influence performance in virtual settings.”

Step 6: End with a Thesis Statement or Hypothesis

Wrap up the introduction with a clear thesis statement or hypothesis that provides a concise summary of the paper’s main argument or expected findings.

Example : “The study hypothesizes that remote work environments enhance productivity due to reduced commute times, flexible schedules, and a more personalized workspace.”

Examples of Research Paper Introductions

Example 1: social media and mental health.

Hook : “With over 3.6 billion people using social media globally, digital interactions are now a significant part of everyday life.”

Background : “While social media platforms provide opportunities for connection, recent studies suggest that excessive use may have negative implications for mental health, particularly among young adults.”

Research Problem : “Despite the prevalence of social media, its impact on mental health remains underexplored, especially concerning anxiety and self-esteem.”

Purpose and Significance : “By examining the relationship between social media use and mental well-being, this study aims to provide insights that can inform healthier digital habits.”

Research Question : “What is the relationship between social media use and levels of anxiety and self-esteem among young adults?”

Thesis Statement : “This paper posits that excessive social media use is associated with higher levels of anxiety and lower self-esteem.”

Example 2: Renewable Energy Adoption

Hook : “As the world grapples with climate change, renewable energy sources offer a sustainable solution for reducing carbon emissions.”

Background : “The shift toward renewable energy has accelerated in recent years, with solar, wind, and hydroelectric power accounting for a growing share of global energy production.”

Research Problem : “However, the adoption of renewable energy varies significantly between developed and developing countries, and factors influencing this disparity are not fully understood.”

Purpose and Significance : “This study examines the barriers to renewable energy adoption in developing countries, identifying key economic, social, and policy challenges.”

Research Question : “What are the primary barriers to renewable energy adoption in developing nations, and how can these be addressed?”

Thesis Statement : “The paper argues that economic constraints and lack of supportive policies are the main obstacles to renewable energy adoption in developing countries.”

Tips for Writing an Effective Research Paper Introduction

• Be Clear and Concise : Avoid unnecessary details. Stick to key points that introduce the topic and set up your study.
• Engage the Reader : Use an interesting hook or fact to draw the reader in and make them curious about your research.
• Provide Relevant Background : Offer just enough context to help readers understand the topic without overwhelming them.
• State the Research Problem : Clearly articulate the issue or gap that your research addresses, as this helps justify the study.
• Write a Strong Thesis Statement : Ensure your thesis statement or hypothesis clearly reflects the main objective of the study.

Common Mistakes to Avoid

• Being Too Vague : Avoid general statements that lack specificity. Clearly define your topic and research problem.
• Providing Too Much Detail : Keep background information brief and to the point; avoid including data or analysis in the introduction.
• Forgetting the Research Problem : Make sure to state the research problem or gap, as it helps readers understand the study’s purpose.
• Weak Thesis Statement : Avoid vague or broad thesis statements. A strong thesis provides a clear direction for the study.

A well-structured introduction is essential for capturing the reader’s attention and setting up the foundation of a research paper. By including a compelling hook, relevant background, a defined research problem, clear objectives, and a concise thesis statement, you can craft an effective introduction that guides readers into your study. Remember to maintain clarity, stay focused, and emphasize the significance of your research.

How to Write an Introduction

An introduction for an essay or research paper is the first paragraph, which explains the topic and prepares the reader for the rest of the work. Because it’s responsible for both the reader’s first impression and setting the stage for the rest of the work, the introduction paragraph is arguably the most important paragraph in the work. 

Knowing how to write an introduction paragraph is a great skill, not just for writers, but for students and researchers as well. Here, we explain everything you need to know to write the best introduction, such as what to include and a step-by-step process, with some introduction paragraph examples. 

Give your writing extra polish Grammarly helps you communicate confidently Write with Grammarly

What is an introduction?

Your introduction is a way of preparing your reader for your paper. As the first paragraph of your writing , it makes the first impression and sets the reader’s expectations for tone, voice, and writing style. More importantly, your introduction provides the necessary background for your reader to understand your paper’s purpose and key points. 

The introduction is also a way to engage and captivate your reader. An interesting, thought-provoking, or generally entertaining introduction makes your reader excited to keep reading—and an eager reader is an attentive reader.  

What to include in an introduction

Introductions generally follow the writing style of the author and the format for the type of paper—for example, opening with a joke is appropriate for some essays, but not research papers . However, no matter what your writing style is or what kind of paper you’re writing, a good introduction includes at least three parts: 

• A hook to capture the reader’s attention
• Background for context
• A clearly defined thesis statement or main point of your paper

How to write a hook

The hook refers to anything that grabs (or “hooks”) your reader’s attention and makes them interested. This could be a mystery, such as posing a question and only answering it at the end of your paper. Or it could be a shocking statistic, something that makes your reader rethink what they thought they knew and become curious for more information. 

Hooks can be even more creative. Some papers start with an analogy or parable to present complicated topics in a way that someone with little experience can understand. Likewise, many writers opt to use personal anecdotes to show a more human side and spark an emotional connection with the reader. 

When all else fails, you can use a poignant quote. If you’re having trouble putting your thoughts into words, maybe one of the great minds from history has already said it well. 

You can read all about how to write a hook here, including more detailed instructions and examples. 

How to add background information

Not every paper requires background knowledge, but sometimes your reader needs to catch up or understand the context before you make your original points. 

If you’re writing about something factual, such as a scientific or historical paper, you may need to provide a small lesson on the basics. For example, if you’re writing about the conflict between ancient Egypt and Nubia, you might want to establish the time period and where each party was located geographically. 

Just don’t give too much away in the introduction. In general, introductions should be short. If your topic requires extensive background to understand, it’s best to dedicate a few paragraphs to this after the introduction. 

How to write a thesis statement

Every good introduction needs a thesis statement , a sentence that plainly and concisely explains the main topic. Thesis statements are often just a brief summary of your entire paper, including your argument or point of view for personal essays. For example, if your paper is about whether viewing violent cartoons impacts real-life violence, your thesis statement could be: 

Despite the rhetoric and finger-pointing, no evidence has connected live-action role-play violence with real-world violence, but there is plenty of evidence for exoneration, as I explain here.  

Learning to write a good thesis statement is an essential writing skill, both in college and the world of work, so it’s worth taking the time to learn. The rule of thumb for thesis statements is not to give everything away all at once. Thesis statements, and more broadly introductions, should be short and to the point, so save the details for the rest of the paper. 

How to write an introduction paragraph in 6 steps

1 decide on the overall tone and formality of your paper.

Often what you’re writing determines the style: The guidelines for how to write an introduction for a report are different from those for how to write an English essay introduction. Even the different types of essays have their own limitations; for example, slang might be acceptable for a personal essay, but not a serious argumentative essay. 

Don’t force yourself to write in a style that’s uncomfortable to you. If you’re not good at making jokes, you don’t need to. As long as your writing is interesting and your points are clear, your readers won’t mind.  

2 Write your thesis statement 

At the beginning of writing a paper, even before writing the research paper outline , you should know what your thesis is. If you haven’t already, now is the time to put that thesis into words by writing your thesis statement. 

Thesis statements are just one sentence, but they are usually the most important sentence in your entire work. When your thesis is clearly defined, your readers will often use it as an anchor to understand the rest of the writing. 

The key to writing a good thesis statement is knowing what to ignore. Your thesis statement should be an overview, not an outline. Save the details, evidence, and personal opinions for the body of the paper. 

If you’re still having trouble, ask yourself how you’d explain this topic to a child. When you’re forced to use small words and simplify complex ideas, your writing comes across more clearly and is easier to understand. This technique also helps you know which details are necessary up front and which can wait until later .

3 Consider what background information your reader needs 

Don’t take your own experience for granted. By this point in the writing process , you’ve probably already finished your research, which means you’re somewhat of an expert on the topic. Think back to what it was like before you learned: What did you wish you had known then? 

Even if your topic is abstract, such as an ethical debate, consider including some context on the debate itself. How long has the ethical debate been happening? Was there a specific event that started it? Information like this can help set the scene so your reader doesn’t feel like they’re missing something. 

4 Think of a good hook

Writing a hook can be the most difficult part of writing an introduction because it calls for some creativity. While the rest of your paper might be presenting fact after fact, the hook in your introduction often requires creating something from nothing. 

Luckily, there are already plenty of tried-and-true strategies for how to start an essay . If you’re not feeling very creative, you can use a method that’s already been proven effective. 

Just remember that the best hooks create an emotional connection—which emotion is up to you and your topic. 

5 Write a rough draft of your introduction without pressure

It’s normal to clam up when writing a rough draft of your introduction. After all, the introduction always comes first, so it’s the first thing you write when you finally begin. 

As explained in our guide to writing a rough draft , the best advice is not to pressure yourself. It’s OK to write something that’s messy—that’s what makes this draft rough . The idea here is to get words on paper that make your point. They don’t have to be the perfect words; that’s what revisions are for. 

At the beginning, just worry about saying what needs to be said. Get down your hook and thesis statement, and background information if necessary, without worrying about how it sounds. You’ll be able to fix the problems later.

6 Revise your introduction after you’ve written your whole paper.

We recommend finishing the first draft of your entire paper before revising the introduction. You may make some changes in your paper’s structure when writing the first draft, and those changes should be reflected in the introduction.

After the first draft, it’s easier to focus on minutiae like word choice and sentence structure, not to mention finding spelling and grammar mistakes.

Introduction for an essay example

While other kids’ memories of circuses are happy and fun, what I recall most from my first time at a circus was feeling sorry for the animals—I can still remember the sadness in their eyes. [HOOK] Although animal rights in the circus have come a long way, their treatment of animals even under the new laws is still cruelty plain and simple. [BACKGROUND] The way circuses abuse animals needs to be abolished immediately, and we need to entirely rethink the way we use animals for entertainment. [THESIS STATEMENT]  

Introduction for a research paper example

What would happen to humanity if everyone just stopped having babies? [HOOK] Although more endemic in some places than others, the global decline in birth rates has become a major issue since the end of the pandemic. [BACKGROUND] My research here shows not only that birth rates are declining all over the world, but also that unless the threats are addressed, these drastic declines will only get worse. [THESIS STATEMENT] 

Introduction FAQs

An introduction is the first paragraph in an essay or research paper. It prepares the reader for what follows. 

What’s the purpose of an introduction?

The goal of the introduction is to both provide the necessary context for the topic so the reader can follow along and also create an emotional connection so the reader wants to keep reading. 

What should an introduction include?

An introduction should include three things: a hook to interest the reader, some background on the topic so the reader can understand it, and a thesis statement that clearly and quickly summarizes your main point.

However, the introduction is a vital element of your research paper . It helps the reader decide whether your paper is worth their time. As such, it's worth taking your time to get it right.

In this article, we'll tell you everything you need to know about writing an effective introduction for your research paper.

• The importance of an introduction in research papers

The primary purpose of an introduction is to provide an overview of your paper. This lets readers gauge whether they want to continue reading or not. The introduction should provide a meaningful roadmap of your research to help them make this decision. It should let readers know whether the information they're interested in is likely to be found in the pages that follow.

Aside from providing readers with information about the content of your paper, the introduction also sets the tone. It shows readers the style of language they can expect, which can further help them to decide how far to read.

When you take into account both of these roles that an introduction plays, it becomes clear that crafting an engaging introduction is the best way to get your paper read more widely. First impressions count, and the introduction provides that impression to readers.

• The optimum length for a research paper introduction

While there's no magic formula to determine exactly how long a research paper introduction should be, there are a few guidelines. Some variables that impact the ideal introduction length include:

Field of study

Complexity of the topic

Specific requirements of the course or publication

A commonly recommended length of a research paper introduction is around 10% of the total paper’s length. So, a ten-page paper has a one-page introduction. If the topic is complex, it may require more background to craft a compelling intro. Humanities papers tend to have longer introductions than those of the hard sciences.

The best way to craft an introduction of the right length is to focus on clarity and conciseness. Tell the reader only what is necessary to set up your research. An introduction edited down with this goal in mind should end up at an acceptable length.

• Evaluating successful research paper introductions

A good way to gauge how to create a great introduction is by looking at examples from across your field. The most influential and well-regarded papers should provide some insights into what makes a good introduction.

Dissecting examples: what works and why

We can make some general assumptions by looking at common elements of a good introduction, regardless of the field of research.

A common structure is to start with a broad context, and then narrow that down to specific research questions or hypotheses. This creates a funnel that establishes the scope and relevance.

The most effective introductions are careful about the assumptions they make regarding reader knowledge. By clearly defining key terms and concepts instead of assuming the reader is familiar with them, these introductions set a more solid foundation for understanding.

To pull in the reader and make that all-important good first impression, excellent research paper introductions will often incorporate a compelling narrative or some striking fact that grabs the reader's attention.

Finally, good introductions provide clear citations from past research to back up the claims they're making. In the case of argumentative papers or essays (those that take a stance on a topic or issue), a strong thesis statement compels the reader to continue reading.

Common pitfalls to avoid in research paper introductions

You can also learn what not to do by looking at other research papers. Many authors have made mistakes you can learn from.

We've talked about the need to be clear and concise. Many introductions fail at this; they're verbose, vague, or otherwise fail to convey the research problem or hypothesis efficiently. This often comes in the form of an overemphasis on background information, which obscures the main research focus.

Ensure your introduction provides the proper emphasis and excitement around your research and its significance. Otherwise, fewer people will want to read more about it.

• Crafting a compelling introduction for a research paper

Let’s take a look at the steps required to craft an introduction that pulls readers in and compels them to learn more about your research.

Step 1: Capturing interest and setting the scene

To capture the reader's interest immediately, begin your introduction with a compelling question, a surprising fact, a provocative quote, or some other mechanism that will hook readers and pull them further into the paper.

As they continue reading, the introduction should contextualize your research within the current field, showing readers its relevance and importance. Clarify any essential terms that will help them better understand what you're saying. This keeps the fundamentals of your research accessible to all readers from all backgrounds.

Step 2: Building a solid foundation with background information

Including background information in your introduction serves two major purposes:

It helps to clarify the topic for the reader

It establishes the depth of your research

The approach you take when conveying this information depends on the type of paper.

For argumentative papers, you'll want to develop engaging background narratives. These should provide context for the argument you'll be presenting.

For empirical papers, highlighting past research is the key. Often, there will be some questions that weren't answered in those past papers. If your paper is focused on those areas, those papers make ideal candidates for you to discuss and critique in your introduction.

Step 3: Pinpointing the research challenge

To capture the attention of the reader, you need to explain what research challenges you'll be discussing.

For argumentative papers, this involves articulating why the argument you'll be making is important. What is its relevance to current discussions or problems? What is the potential impact of people accepting or rejecting your argument?

For empirical papers, explain how your research is addressing a gap in existing knowledge. What new insights or contributions will your research bring to your field?

Step 4: Clarifying your research aims and objectives

We mentioned earlier that the introduction to a research paper can serve as a roadmap for what's within. We've also frequently discussed the need for clarity. This step addresses both of these.

When writing an argumentative paper, craft a thesis statement with impact. Clearly articulate what your position is and the main points you intend to present. This will map out for the reader exactly what they'll get from reading the rest.

For empirical papers, focus on formulating precise research questions and hypotheses. Directly link them to the gaps or issues you've identified in existing research to show the reader the precise direction your research paper will take.

Step 5: Sketching the blueprint of your study

Continue building a roadmap for your readers by designing a structured outline for the paper. Guide the reader through your research journey, explaining what the different sections will contain and their relationship to one another.

This outline should flow seamlessly as you move from section to section. Creating this outline early can also help guide the creation of the paper itself, resulting in a final product that's better organized. In doing so, you'll craft a paper where each section flows intuitively from the next.

Step 6: Integrating your research question

To avoid letting your research question get lost in background information or clarifications, craft your introduction in such a way that the research question resonates throughout. The research question should clearly address a gap in existing knowledge or offer a new perspective on an existing problem.

Tell users your research question explicitly but also remember to frequently come back to it. When providing context or clarification, point out how it relates to the research question. This keeps your focus where it needs to be and prevents the topic of the paper from becoming under-emphasized.

Step 7: Establishing the scope and limitations

So far, we've talked mostly about what's in the paper and how to convey that information to readers. The opposite is also important. Information that's outside the scope of your paper should be made clear to the reader in the introduction so their expectations for what is to follow are set appropriately.

Similarly, be honest and upfront about the limitations of the study. Any constraints in methodology, data, or how far your findings can be generalized should be fully communicated in the introduction.

Step 8: Concluding the introduction with a promise

The final few lines of the introduction are your last chance to convince people to continue reading the rest of the paper. Here is where you should make it very clear what benefit they'll get from doing so. What topics will be covered? What questions will be answered? Make it clear what they will get for continuing.

By providing a quick recap of the key points contained in the introduction in its final lines and properly setting the stage for what follows in the rest of the paper, you refocus the reader's attention on the topic of your research and guide them to read more.

• Research paper introduction best practices

Following the steps above will give you a compelling introduction that hits on all the key points an introduction should have. Some more tips and tricks can make an introduction even more polished.

As you follow the steps above, keep the following tips in mind.

Set the right tone and style

Like every piece of writing, a research paper should be written for the audience. That is to say, it should match the tone and style that your academic discipline and target audience expect. This is typically a formal and academic tone, though the degree of formality varies by field.

Kno w the audience

The perfect introduction balances clarity with conciseness. The amount of clarification required for a given topic depends greatly on the target audience. Knowing who will be reading your paper will guide you in determining how much background information is required.

Adopt the CARS (create a research space) model

The CARS model is a helpful tool for structuring introductions. This structure has three parts. The beginning of the introduction establishes the general research area. Next, relevant literature is reviewed and critiqued. The final section outlines the purpose of your study as it relates to the previous parts.

Master the art of funneling

The CARS method is one example of a well-funneled introduction. These start broadly and then slowly narrow down to your specific research problem. It provides a nice narrative flow that provides the right information at the right time. If you stray from the CARS model, try to retain this same type of funneling.

Incorporate narrative element

People read research papers largely to be informed. But to inform the reader, you have to hold their attention. A narrative style, particularly in the introduction, is a great way to do that. This can be a compelling story, an intriguing question, or a description of a real-world problem.

Write the introduction last

By writing the introduction after the rest of the paper, you'll have a better idea of what your research entails and how the paper is structured. This prevents the common problem of writing something in the introduction and then forgetting to include it in the paper. It also means anything particularly exciting in the paper isn’t neglected in the intro.

• If you are writing in a new discipline, you should always make sure to ask about conventions and expectations for introductions, just as you would for any other aspect of the essay. For example, while it may be acceptable to write a two-paragraph (or longer) introduction for your papers in some courses, instructors in other disciplines, such as those in some Government courses, may expect a shorter introduction that includes a preview of the argument that will follow.  
• In some disciplines (Government, Economics, and others), it’s common to offer an overview in the introduction of what points you will make in your essay. In other disciplines, you will not be expected to provide this overview in your introduction.  
• Avoid writing a very general opening sentence. While it may be true that “Since the dawn of time, people have been telling love stories,” it won’t help you explain what’s interesting about your topic.  
• Avoid writing a “funnel” introduction in which you begin with a very broad statement about a topic and move to a narrow statement about that topic. Broad generalizations about a topic will not add to your readers’ understanding of your specific essay topic.  
• Avoid beginning with a dictionary definition of a term or concept you will be writing about. If the concept is complicated or unfamiliar to your readers, you will need to define it in detail later in your essay. If it’s not complicated, you can assume your readers already know the definition.  
• Avoid offering too much detail in your introduction that a reader could better understand later in the paper.
