Writing a Research Paper Introduction | Step-by-Step Guide
Published on September 24, 2022 by Jack Caulfield . Revised on November 29, 2022.
The introduction to a research paper is where you set up your topic and approach for the reader. It has several key goals:
- Present your topic and get the reader interested
- Provide background or summarize existing research
- Position your own approach
- Detail your specific research problem and problem statement
- Give an overview of the paper’s structure
The introduction looks slightly different depending on whether your paper presents the results of original empirical research or constructs an argument by engaging with a variety of sources.
Table of contents
Step 1: introduce your topic, step 2: describe the background, step 3: establish your research problem, step 4: specify your objective(s), step 5: map out your paper, research paper introduction examples, frequently asked questions about the research paper introduction.
The first job of the introduction is to tell the reader what your topic is and why it’s interesting or important. This is generally accomplished with a strong opening hook.
The hook is a striking opening sentence that clearly conveys the relevance of your topic. Think of an interesting fact or statistic, a strong statement, a question, or a brief anecdote that will get the reader wondering about your topic.
For example, the following could be an effective hook for an argumentative paper about the environmental impact of cattle farming:
A more empirical paper investigating the relationship of Instagram use with body image issues in adolescent girls might use the following hook:
Don’t feel that your hook necessarily has to be deeply impressive or creative. Clarity and relevance are still more important than catchiness. The key thing is to guide the reader into your topic and situate your ideas.
This part of the introduction differs depending on what approach your paper is taking.
In a more argumentative paper, you’ll explore some general background here. In a more empirical paper, this is the place to review previous research and establish how yours fits in.
Argumentative paper: Background information
After you’ve caught your reader’s attention, specify a bit more, providing context and narrowing down your topic.
Provide only the most relevant background information. The introduction isn’t the place to get too in-depth; if more background is essential to your paper, it can appear in the body .
Empirical paper: Describing previous research
For a paper describing original research, you’ll instead provide an overview of the most relevant research that has already been conducted. This is a sort of miniature literature review —a sketch of the current state of research into your topic, boiled down to a few sentences.
This should be informed by genuine engagement with the literature. Your search can be less extensive than in a full literature review, but a clear sense of the relevant research is crucial to inform your own work.
Begin by establishing the kinds of research that have been done, and end with limitations or gaps in the research that you intend to respond to.

The next step is to clarify how your own research fits in and what problem it addresses.
Argumentative paper: Emphasize importance
In an argumentative research paper, you can simply state the problem you intend to discuss, and what is original or important about your argument.
Empirical paper: Relate to the literature
In an empirical research paper, try to lead into the problem on the basis of your discussion of the literature. Think in terms of these questions:
- What research gap is your work intended to fill?
- What limitations in previous work does it address?
- What contribution to knowledge does it make?
You can make the connection between your problem and the existing research using phrases like the following.
Now you’ll get into the specifics of what you intend to find out or express in your research paper.
The way you frame your research objectives varies. An argumentative paper presents a thesis statement, while an empirical paper generally poses a research question (sometimes with a hypothesis as to the answer).
Argumentative paper: Thesis statement
The thesis statement expresses the position that the rest of the paper will present evidence and arguments for. It can be presented in one or two sentences, and should state your position clearly and directly, without providing specific arguments for it at this point.
Empirical paper: Research question and hypothesis
The research question is the question you want to answer in an empirical research paper.
Present your research question clearly and directly, with a minimum of discussion at this point. The rest of the paper will be taken up with discussing and investigating this question; here you just need to express it.
A research question can be framed either directly or indirectly.
- This study set out to answer the following question: What effects does daily use of Instagram have on the prevalence of body image issues among adolescent girls?
- We investigated the effects of daily Instagram use on the prevalence of body image issues among adolescent girls.
If your research involved testing hypotheses , these should be stated along with your research question. They are usually presented in the past tense, since the hypothesis will already have been tested by the time you are writing up your paper.
For example, the following hypothesis might respond to the research question above:
The final part of the introduction is often dedicated to a brief overview of the rest of the paper.
In a paper structured using the standard scientific “introduction, methods, results, discussion” format, this isn’t always necessary. But if your paper is structured in a less predictable way, it’s important to describe the shape of it for the reader.
If included, the overview should be concise, direct, and written in the present tense.
- This paper will first discuss several examples of survey-based research into adolescent social media use, then will go on to …
- This paper first discusses several examples of survey-based research into adolescent social media use, then goes on to …

Are cows responsible for climate change? A recent study (RIVM, 2019) shows that cattle farmers account for two thirds of agricultural nitrogen emissions in the Netherlands. These emissions result from nitrogen in manure, which can degrade into ammonia and enter the atmosphere. The study’s calculations show that agriculture is the main source of nitrogen pollution, accounting for 46% of the country’s total emissions. By comparison, road traffic and households are responsible for 6.1% each, the industrial sector for 1%. While efforts are being made to mitigate these emissions, policymakers are reluctant to reckon with the scale of the problem. The approach presented here is a radical one, but commensurate with the issue. This paper argues that the Dutch government must stimulate and subsidize livestock farmers, especially cattle farmers, to transition to sustainable vegetable farming. It first establishes the inadequacy of current mitigation measures, then discusses the various advantages of the results proposed, and finally addresses potential objections to the plan on economic grounds.
The rise of social media has been accompanied by a sharp increase in the prevalence of body image issues among women and girls. This correlation has received significant academic attention: Various empirical studies have been conducted into Facebook usage among adolescent girls (Tiggermann & Slater, 2013; Meier & Gray, 2014). These studies have consistently found that the visual and interactive aspects of the platform have the greatest influence on body image issues. Despite this, highly visual social media (HVSM) such as Instagram have yet to be robustly researched. This paper sets out to address this research gap. We investigated the effects of daily Instagram use on the prevalence of body image issues among adolescent girls. It was hypothesized that daily Instagram use would be associated with an increase in body image concerns and a decrease in self-esteem ratings.
The introduction of a research paper includes several key elements:
- A hook to catch the reader’s interest
- Relevant background on the topic
- Details of your research problem
and your problem statement
- A thesis statement or research question
- Sometimes an overview of the paper
Don’t feel that you have to write the introduction first. The introduction is often one of the last parts of the research paper you’ll write, along with the conclusion.
This is because it can be easier to introduce your paper once you’ve already written the body ; you may not have the clearest idea of your arguments until you’ve written them, and things can change during the writing process .
The way you present your research problem in your introduction varies depending on the nature of your research paper . A research paper that presents a sustained argument will usually encapsulate this argument in a thesis statement .
A research paper designed to present the results of empirical research tends to present a research question that it seeks to answer. It may also include a hypothesis —a prediction that will be confirmed or disproved by your research.

The Research Paper
There will come a time in most students' careers when they are assigned a research paper. Such an assignment often creates a great deal of unneeded anxiety in the student, which may result in procrastination and a feeling of confusion and inadequacy. This anxiety frequently stems from the fact that many students are unfamiliar and inexperienced with this genre of writing. Never fear—inexperience and unfamiliarity are situations you can change through practice! Writing a research paper is an essential aspect of academics and should not be avoided on account of one's anxiety. In fact, the process of writing a research paper can be one of the more rewarding experiences one may encounter in academics. What is more, many students will continue to do research throughout their careers, which is one of the reasons this topic is so important.
Becoming an experienced researcher and writer in any field or discipline takes a great deal of practice. There are few individuals for whom this process comes naturally. Remember, even the most seasoned academic veterans have had to learn how to write a research paper at some point in their career. Therefore, with diligence, organization, practice, a willingness to learn (and to make mistakes!), and, perhaps most important of all, patience, students will find that they can achieve great things through their research and writing.
The pages in this section cover the following topic areas related to the process of writing a research paper:
- Genre - This section will provide an overview for understanding the difference between an analytical and argumentative research paper.
- Choosing a Topic - This section will guide the student through the process of choosing topics, whether the topic be one that is assigned or one that the student chooses themselves.
- Identifying an Audience - This section will help the student understand the often times confusing topic of audience by offering some basic guidelines for the process.
- Where Do I Begin - This section concludes the handout by offering several links to resources at Purdue, and also provides an overview of the final stages of writing a research paper.
The Ultimate Guide to Writing a Research Paper
Few things strike more fear in academics than the accursed research paper , a term synonymous with long hours and hard work. Luckily there’s a secret to help you get through them. As long as you know how to write a research paper properly, you’ll find they’re not so bad . . . or at least less painful.
In this guide we concisely explain how to write an academic research paper step by step. We’ll cover areas like how to start a research paper, how to write a research paper outline, how to use citations and evidence, and how to write a conclusion for a research paper.
But before we get into the details, let’s take a look at what a research paper is and how it’s different from other writing .

What is a research paper?
A research paper is a type of academic writing that provides an in-depth analysis, evaluation, or interpretation of a single topic, based on empirical evidence. Research papers are similar to analytical essays, except that research papers emphasize the use of statistical data and preexisting research, along with a strict code for citations.
Research papers are a bedrock of modern science and the most effective way to share information across a wide network. However, most people are familiar with research papers from school; college courses often use them to test a student’s knowledge of a particular area or their research skills in general.
Considering their gravity, research papers favor formal, even bland language that strips the writing of any bias. Researchers state their findings plainly and with corresponding evidence so that other researchers can consequently use the paper in their own research.
Keep in mind that writing a research paper is different from writing a research proposal . Essentially, research proposals are to acquire the funding needed to get the data to write a research paper.
How long should a research paper be?
The length of a research paper depends on the topic or assignment. Typically, research papers run around 4,000–6,000 words, but it’s common to see short papers around 2,000 words or long papers over 10,000 words.
If you’re writing a paper for school, the recommended length should be provided in the assignment. Otherwise, let your topic dictate the length: Complicated topics or extensive research will require more explanation.
How to write a research paper in 9 steps
Below is a step-by-step guide to writing a research paper, catered specifically for students rather than professional researchers. While some steps may not apply to your particular assignment, think of this as more of a general guideline to keep you on track.
1 Understand the assignment
For some of you this goes without saying, but you might be surprised at how many students start a research paper without even reading the assignment guidelines.
So your first step should be to review the assignment and carefully read the writing prompt. Specifically, look for technical requirements such as length , formatting requirements (single- vs. double-spacing, indentations, etc.) and citation style . Also pay attention to the particulars, such as whether or not you need to write an abstract or include a cover page.
Once you understand the assignment, the next steps in how to write a research paper follow the usual writing process , more or less. There are some extra steps involved because research papers have extra rules, but the gist of the writing process is the same.
2 Choose your topic
In open-ended assignments, the student must choose their own topic. While it may seem simple enough, choosing a topic is actually the most important decision you’ll make in writing a research paper, since it determines everything that follows.
Your top priority in how to choose a research paper topic is whether it will provide enough content and substance for an entire research paper. You’ll want to choose a topic with enough data and complexity to enable a rich discussion. However, you also want to avoid general topics and instead stick with topics specific enough that you can cover all the relevant information without cutting too much.
Try not to be robotic about choosing your topic, though; it’s still best to pick something that you’re personally interested in. Ideally, you’ll find a topic that satisfies both requirements, something that provides a suitable amount of content and also keeps you engaged.
3 Gather preliminary research
The sooner you start researching, the better—after all, it’s called a research paper for a reason.
To refine your topic and prepare your thesis statement, find out what research is available for your topic as soon as possible. Early research can help dispel any misconceptions you have about the topic and reveal the best paths and approaches to find more material.
Typically, you can find sources either online or in a library. If you’re searching online, make sure you use credible sources like science journals or academic papers. Some search engines—mentioned below in the Tools and resources section—allow you to browse only accredited sources and academic databases.
Keep in mind the difference between primary and secondary sources as you search. Primary sources are firsthand accounts, like published articles or autobiographies; secondary sources are more removed, like critical reviews or secondhand biographies.
When gathering your research, it’s better to skim sources instead of reading each potential source fully. If a source seems useful, set it aside to give it a full read later. Otherwise, you’ll be stuck poring over sources that you ultimately won’t use, and that time could be better spent finding a worthwhile source.
Sometimes you’re required to submit a literature review , which explains your sources and presents them to an authority for confirmation. Even if no literature review is required, it’s still helpful to compile an early list of potential sources—you’ll be glad you did later.
4 Write a thesis statement
Using what you found in your preliminary research, write a thesis statement that succinctly summarizes what your research paper will be about. This is usually the first sentence in your paper, making it your reader’s introduction to the topic.
A thesis statement is the best answer for how to start a research paper. Aside from preparing your reader, the thesis statement also makes it easier for other researchers to assess whether or not your paper is useful to them for their own research. Likewise, you should read the thesis statements of other research papers to decide how useful they are to you.
A good thesis statement mentions all the important parts of the discussion without disclosing too many of the details. If you’re having trouble putting it into words, try to phrase your topic as a question and then answer it .
For example, if your research paper topic is about separating students with ADHD from other students, you’d first ask yourself, “Does separating students with ADHD improve their learning?” The answer—based on your preliminary research—is a good basis for your thesis statement.
5 Determine supporting evidence
At this stage of how to write an academic research paper, it’s time to knuckle down and do the actual research. Here’s when you go through all the sources you collected earlier and find the specific information you’d like to use in your paper.
Normally, you find your supporting evidence by reading each source and taking notes. Isolate only the information that’s directly relevant to your topic; don’t bog down your paper with tangents or unnecessary context, however interesting they may be. And always write down page numbers , not only for you to find the information later, but also because you’ll need them for your citations.
Aside from highlighting text and writing notes, another common tactic is to use bibliography cards . These are simple index cards with a fact or direct quotation on one side and the bibliographical information (source citation, page numbers, subtopic category) on the other. While bibliography cards are not necessary, some students find them useful for staying organized, especially when it’s time to write an outline.
6 Write a research paper outline
A lot of students want to know how to write a research paper outline. More than informal essays, research papers require a methodical and systematic structure to make sure all issues are addressed, and that makes outlines especially important.
First make a list of all the important categories and subtopics you need to cover—an outline for your outline! Consider all the information you gathered when compiling your supporting evidence and ask yourself what the best way to separate and categorize everything is.
Once you have a list of what you want to talk about, consider the best order to present the information. Which subtopics are related and should go next to each other? Are there any subtopics that don’t make sense if they’re presented out of sequence? If your information is fairly straightforward, feel free to take a chronological approach and present the information in the order it happened.
Because research papers can get complicated, consider breaking your outline into paragraphs. For starters, this helps you stay organized if you have a lot of information to cover. Moreover, it gives you greater control over the flow and direction of the research paper. It’s always better to fix structural problems in the outline phase than later after everything’s already been written.
Don’t forget to include your supporting evidence in the outline as well. Chances are you’ll have a lot you want to include, so putting it in your outline helps prevent some things from falling through the cracks.
7 Write the first draft
Once your outline is finished, it’s time to start actually writing your research paper. This is by far the longest and most involved step, but if you’ve properly prepared your sources and written a thorough outline, everything should run smoothly.
If you don’t know how to write an introduction for a research paper, the beginning can be difficult. That’s why writing your thesis statement beforehand is crucial. Open with your thesis statement and then fill out the rest of your introduction with the secondary information—save the details for the body of your research paper, which comes next.
The body contains the bulk of your research paper. Unlike essays , research papers usually divide the body into sections with separate headers to facilitate browsing and scanning. Use the divisions in your outline as a guide.
Follow along your outline and go paragraph by paragraph. Because this is just the first draft, don’t worry about getting each word perfect . Later you’ll be able to revise and fine-tune your writing, but for now focus simply on saying everything that needs to be said. In other words, it’s OK to make mistakes since you’ll go back later to correct them.
One of the most common problems with writing long works like research papers is connecting paragraphs to each other. The longer your writing is, the harder it is to tie everything together smoothly. Use transition sentences to improve the flow of your paper, especially for the first and last sentences in a paragraph.
Even after the body is written, you still need to know how to write a conclusion for a research paper. Just like an essay conclusion , your research paper conclusion should restate your thesis , reiterate your main evidence , and summarize your findings in a way that’s easy to understand.
Don’t add any new information in your conclusion, but feel free to say your own personal perspective or interpretation if it helps the reader understand the big picture.
8 Cite your sources correctly
Citations are part of what sets research papers apart from more casual nonfiction like personal essays . Citing your sources both validates your data and also links your research paper to the greater scientific community. Because of their importance, citations must follow precise formatting rules . . . problem is, there’s more than one set of rules!
You need to check with the assignment to see which formatting style is required. Typically, academic research papers follow one of two formatting styles for citing sources:
- MLA (Modern Language Association)
- APA (American Psychological Association)
The links above explain the specific formatting guidelines for each style, along with an automatic citation generator to help you get started.
In addition to MLA and APA styles, you occasionally see requirements for CMOS (The Chicago Manual of Style), AMA (American Medical Association) and IEEE (Institute of Electrical and Electronics Engineers).
Citations may seem confusing at first with all their rules and specific information. However, once you get the hang of them, you’ll be able to properly cite your sources without even thinking about it. Keep in mind that each formatting style has specific guidelines for citing just about any kind of source, including photos , websites , speeches , and YouTube videos .
9 Edit and proofread
Last but not least, you want to go through your research paper to correct all the mistakes by proofreading . We recommend going over it twice: once for structural issues such as adding/deleting parts or rearranging paragraphs and once for word choice, grammatical, and spelling mistakes. Doing two different editing sessions helps you focus on one area at a time instead of doing them both at once.
To help you catch everything, here’s a quick checklist to keep in mind while you edit:
Structural edit:
- Is your thesis statement clear and concise?
- Is your paper well-organized, and does it flow from beginning to end with logical transitions?
- Do your ideas follow a logical sequence in each paragraph?
- Have you used concrete details and facts and avoided generalizations?
- Do your arguments support and prove your thesis?
- Have you avoided repetition?
- Are your sources properly cited?
- Have you checked for accidental plagiarism?
Word choice, grammar, and spelling edit:
- Is your language clear and specific?
- Do your sentences flow smoothly and clearly?
- Have you avoided filler words and phrases ?
- Have you checked for proper grammar, spelling, and punctuation?
Some people find it useful to read their paper out loud to catch problems they might miss when reading in their head. Another solution is to have someone else read your paper and point out areas for improvement and/or technical mistakes.
Revising is a separate skill from writing, and being good at one doesn’t necessarily make you good at the other. If you want to improve your revision skills, read our guide on self-editing , which includes a more complete checklist and advanced tips on improving your revisions.
Technical issues like grammatical mistakes and misspelled words can be handled effortlessly if you use a spellchecker with your word processor, or even better, a digital writing assistant that also suggests improvements for word choice and tone, like Grammarly (we explain more in the Tools and resources section below).

Research paper FAQs
A research paper is a piece of academic writing that analyzes, evaluates, or interprets a single topic with empirical evidence and statistical data.
When will I need to write a research paper in college?
Many college courses use research papers to test a student’s knowledge of a particular topic or their research skills in general. While research papers depend on the course or professor, you can expect to write at least a few before graduation.
How do I determine a topic for my research paper?
If the topic is not assigned, try to find a topic that’s general enough to provide ample evidence but specific enough that you’re able to cover all the basics. If possible, choose a topic you’re personally interested in—it makes the work easier.
Where can I conduct research for my paper?
Today most research is conducted either online or in libraries. Some topics might benefit from old periodicals like newspapers or magazines, as well as visual media like documentaries. Museums, parks, and historical monuments can also be useful.
How do I cite sources for a research paper?
The correct formatting for citations depends on which style you’re using, so check the assignment guidelines. Most school research reports use either MLA or APA styles, although there are others.
