- The background is an evidence-based argument about why your study is necessary, not a summary of everything published on the topic.
- The background section funnels the reader from broad context to a narrow gap, then delivers 5 linked elements: the research problem, the problem statement, the research question, the research hypothesis, and the research objectives.
- It is usually 10-15% of the total word count for a journal article, which usually means 400-800 words spread across 4-6 short paragraphs.
- Draft the background last, after the results are known, so that the gap you describe is exactly the gap your study closes.
What Is the Background of a Research Paper?
The background is the part of the introduction that explains what is already known about a topic, what remains unknown, and why that unknown matters. It sets up the research problem.
It performs 3 jobs at once:
- Orientation: it gives readers outside the immediate specialty enough context to follow the argument.
- Justification: it shows that the question has not already been answered.
- Framing: it establishes the concepts, variables, and vocabulary used in the rest of the paper.
A useful mental image is an inverted triangle: wide at the top, narrow at the point where your study begins.
Is the background a separate section?
The background may or may not be a separate section. However, even if your journal doesn’t ask for a separate section, you need to provide the study background in your Introduction section.
Why Does the Background Section Matter?
A strong background persuades journal editors, peer reviewers, and readers that the study is necessary. Several desk rejections are decided here, before anyone examines the methods or results.
Consider what each audience is looking for:
| Reader | What they scan for | What weak backgrounds fail to show |
| Journal editor | Fit with the journal scope and novelty | A clearly named gap |
| Peer reviewer | Logical link from gap to method | Justification for the chosen design |
| Grant assessor | Significance and urgency | Consequences of leaving the problem unsolved |
| Practitioner | Applicability to real settings | A defined population and context |
Background, Introduction, and Literature Review: What Is the Difference?
The introduction is the whole opening section; the background is its context-setting core; the literature review is a fuller, critical survey of prior studies. The 3 overlap but are not interchangeable.
| Feature | Background | Literature review |
| Primary purpose | Establish context and justify the gap | Evaluate and synthesize the body of evidence |
| Typical length | 400-800 words in an article | 1,500-8,000 words in a thesis chapter |
| Coverage | Selective: only what is needed | Comprehensive within defined limits |
| Tone | Narrative and directional | Analytical and comparative |
| Placement | Inside the introduction | Separate section or chapter |
In short articles, the 2 are often merged. In dissertations, they are almost always separate: the background goes in Chapter 1 and the literature review occupies Chapter 2.
Step 1: Identifying the Research Problem
The research problem is the engine of the background section. Everything before it builds toward it, and everything after it flows from it.
What is a research problem or research gap?
A research problem is the specific gap, contradiction, or unresolved issue in existing knowledge that a study sets out to address. It identifies what is not yet known or settled about a defined population, variable, or setting, and why that matters enough to investigate.
Where research problems and research gaps come from
- Contradictory findings: 2 credible studies report opposite results.
- Untested populations: an effect established in adults has never been tested in adolescents.
- Methodological limits: previous work relied on self-reported data only.
- Practice-based puzzles: a clinical, engineering, or classroom observation that theory does not explain.
- Policy change: a new regulation creates conditions no one has yet studied.
- Explicit calls: authors of recent papers often name the next study needed in their limitations section.
Testing whether a problem is researchable
A research problem qualifies when all 5 of the following statements are true:
- It can be investigated with data that you can realistically obtain.
- It has not already been settled by existing evidence.
- It concerns a relationship, process, or condition, not merely a fact you could look up.
- It can be studied ethically.
- Someone beyond you would care about the answer.
How Do You Narrow a Broad Topic Into a Research Problem?
Narrow a topic by adding limits: population, variable, setting, and time frame. Each limit converts a general interest into something specific enough to investigate.
| Subject area | Broad topic | Narrowed research problem |
| Public health | Air pollution and health | Whether short-term PM2.5 spikes predict pediatric asthma admissions in Delhi during winter |
| Economics | Minimum wage effects | Whether the 2021 state minimum wage increases changed part-time hours in US quick-service restaurants |
| Psychology | Social media and wellbeing | Whether passive scrolling predicts next-day loneliness in first-year undergraduates |
Step 2: Writing the Problem Statement
The problem statement compresses the research problem into 3-5 sentences that a reader can quote back to you. It is the single most reused sentence group in your paper: it will reappear in your abstract, your proposal, and your grant applications.
The 4-part formula
| Part | Function | Sample phrasing |
| 1. Ideal | State the desired condition | Early screening should identify at-risk patients before symptoms appear. |
| 2. Reality | State the current condition and cite it | Fewer than 30% of eligible patients are screened on schedule. |
| 3. Consequence | Show what the gap costs | Delayed detection raises treatment costs and lowers survival rates. |
| 4. Proposal | Name what your study will do | This study evaluates a text-message reminder system in 4 district clinics. |
Quality checks for a problem statement
- It names a population and a setting.
- It contains at least 1 citation supporting the reality claim.
- It avoids method language: how you will study the problem belongs elsewhere.
- It is written in the present tense.
- It stays under 120 words.
Step 3: Framing the Research Question
The research question converts the problem statement into something answerable. A paper normally carries 1 primary research question and 2-3 secondary ones.
Question types and what they signal
| Type | Typical opening | Design implied |
| Descriptive | What is the prevalence of… | Survey or cross-sectional study |
| Comparative | How does group A differ from group B… | Comparative or quasi-experimental |
| Relational | What is the association between… | Correlational or regression study |
| Causal | Does X cause a change in Y… | Experiment or randomized trial |
| Exploratory | How do participants experience… | Qualitative interview or ethnographic study |
Research question examples
| Subject area | Primary research question |
| Epidemiology | Among adults aged 40-65 in Southeast Asian cities, is a 10-microgram increase in weekly PM2.5 exposure associated with higher blood pressure readings? |
| Linguistics | How do bilingual Grade 3 students in Texas switch codes during unstructured peer talk compared with structured classroom talk? |
What Makes a Strong Research Question?
A strong research question is focused, answerable with available data, and tied directly to the gap. The FINER test is the fastest check: feasible, interesting, novel, ethical, and relevant.
| FINER criterion | Question to ask yourself | Warning sign |
| Feasible | Do I have access to the sample, tools, and time? | The sample size needed exceeds the population available |
| Interesting | Would a colleague want to know the answer? | The answer is obvious in advance |
| Novel | Does this extend, refute, or refine prior work? | A recent meta-analysis already settles it |
| Ethical | Can approval realistically be obtained? | The design requires withholding proven care |
| Relevant | Will the answer change practice, policy, or theory? | No stakeholder is identified |
For clinical and intervention studies, the PICO framework adds precision: population, intervention, comparison, and outcome. Naming all 4 components inside the question prevents drift later.
Step 4: Developing the Research Hypothesis
The research hypothesis is a testable prediction derived from the research question and existing theory. Quantitative studies almost always need one; qualitative and purely exploratory studies usually do not.
Hypothesis vocabulary
- Null hypothesis: predicts no difference, no effect, or no association. It is the statement that statistical tests actually evaluate.
- Alternative hypothesis: predicts that a difference, effect, or association exists.
- Directional hypothesis: specifies the direction of the effect, such as higher, faster, or lower.
- Non-directional hypothesis: predicts a difference without specifying direction.
Rules for writing a defensible hypothesis
- Name the independent and dependent variables
- Use operational definitions: state how each variable is measured.
- Keep it falsifiable: there must be a plausible result that would disprove it.
- Restrict it to 1 relationship. Compound predictions cannot be cleanly rejected.
- Ground it in cited theory or prior findings, not intuition.
Research Hypothesis Examples
Each pair below shows the null and the alternative form for the same study.
| Discipline | Null hypothesis | Alternative hypothesis |
| Pharmacology | Drug X produces no difference in mean HbA1c at 12 weeks compared with placebo. | Drug X lowers mean HbA1c by at least 0.5 percentage points at 12 weeks compared with placebo. |
| Agronomy | Drip irrigation and flood irrigation yield equal wheat output per hectare. | Drip irrigation yields higher wheat output per hectare than flood irrigation under identical fertilizer input. |
Note the pattern: the null is always the conservative claim, and the alternative always carries a measurable threshold or direction.
Step 5: Stating the Research Objectives
Research objectives translate the question into planned actions. They are usually presented as 1 general objective followed by 3-5 specific objectives.
Choosing the right verbs
| Use these verbs | Avoid these verbs | Reason |
| Determine, measure, compare | Understand, appreciate | Vague verbs cannot be verified |
| Evaluate, estimate, model | Learn about, look at | Informal verbs suggest no defined output |
| Identify, classify, quantify | Study, explore broadly | Unbounded verbs invite scope creep |
Examples of research objectives
| Subject area | General objective and 1 specific objective |
| Public health | General: to evaluate the effect of SMS reminders on cervical cancer screening uptake. Specific: to compare screening completion rates between reminder and control arms at 6 months. |
| Architecture | General: to assess thermal comfort in naturally ventilated low-cost housing. Specific: to measure indoor operative temperature across 3 orientations during peak summer weeks. |
| Political science | General: to examine determinants of local voter turnout. Specific: to estimate the association between ward-level polling station distance and turnout in 2 municipal elections. |
Apply the SMART filter to each objective: specific, measurable, achievable, relevant, and time-bound.
How Do Research Objectives Differ From Research Questions?
Research questions ask what you want to know; research objectives state what you will do to find out. Questions end with a question mark, while objectives begin with an action verb.
| Feature | Research question | Research objective |
| Grammar | Interrogative sentence | Infinitive phrase starting with to |
| Focus | The knowledge sought | The activity performed |
| Example | Does mulching reduce soil moisture loss in sandy loam? | To measure soil moisture retention in mulched and unmulched plots over 8 weeks |
| Typical count | 1 primary plus 2-3 secondary | 1 general plus 3-5 specific |
Keep them numbered in parallel: specific objective 1 should answer secondary question 1. Reviewers check this alignment.
How Long Should the Background Section Be?
Most journal articles need a background section of around 400-800 words, which is roughly 10-15% of the manuscript. Dissertations allow far more, typically 2,000-5,000 words in the opening chapter.
| Document type | Background length | Approximate citations |
| Research paper | 400-800 words | 15-30 |
| Conference paper | 250-450 words | 8-15 |
| Master’s thesis | 1,500-3,000 words | 30-60 |
| Doctoral dissertation | 3,000-5,000 words | 60-120 |
| Research proposal | 500-1,000 words | 20-40 |
Always check the target journal’s author guidelines first: some cap the entire introduction at 500 words.
Structuring the Background: A Paragraph-by-Paragraph Blueprint
The blueprint below works for a standard 600-word background. Adjust proportions rather than adding paragraphs.
| Paragraph | Function | Approximate share |
| 1 | Establish the broad importance of the topic with 2-3 anchor citations | 15% |
| 2 | Summarize what is firmly established in the field | 25% |
| 3 | Present conflicting findings or unresolved debates | 20% |
| 4 | Name the gap explicitly and state its consequences | 20% |
| 5 | State the research problem, purpose, and objectives | 20% |
Transition phrases that signal the funnel
- Moving from context to evidence: consistent with this, evidence from 3 cohorts indicates…
- Introducing conflict: findings are not uniform; 2 recent trials report the opposite pattern…
- Naming the gap: no study has yet examined this relationship in low-resource settings…
- Stating purpose: the present study therefore evaluates…
Choosing and Citing Evidence for the Background
Selectivity matters more than volume. Cite the studies that build the argument, not every study you read. In many fields, grey literature is also allowed in the background section.
Source priority
- Systematic reviews and meta-analyses: use these for established consensus.
- Primary studies from the last 5 years: use these to establish currency.
- Landmark older papers: use these when defining a construct or method.
- Official statistics and registries: use these for prevalence, cost, and burden claims.
- Preprints: use sparingly, and label them as preprints.
Citation practices to follow
- Attach a citation to every numerical claim, without exception.
- Prefer 2-3 strong sources over 8 weak ones for a single point.
- Read the original: do not cite a paper you have only seen quoted elsewhere.
- Check that the cited study’s population matches the claim you are making.
- Balance the evidence: include the studies that complicate your position.
Language and Style Rules for the Background
Tense choice signals the status of each claim, so it carries meaning rather than merely style.
| Content type | Tense | Example |
| Established knowledge | Present simple | Chronic stress impairs immune response. |
| Findings of a specific study | Past simple | Sharma et al. reported a 12% reduction. |
| Ongoing debate or trend | Present perfect | Researchers have questioned this threshold. |
| Your own study’s purpose | Present simple or future | This study evaluates 3 aggregation strategies. |
Style checklist
- Write in the third person unless the journal permits first person.
- Expand every abbreviation at first use, then use the short form consistently.
- Keep sentences under 25 words on average; vary length deliberately.
- Replace vague words such as “somewhat” and “rather” with specific figures.
- Use a variety of reporting verbs, and not just “shows” when talking about previous research.
- Define ambiguous terms operationally the first time they appear.
- Remove filler openers such as “it is well known that”.
Common Mistakes to Avoid in the Background Section
| Mistake | Why it weakens the paper | Fix |
| Starting too broadly | Wastes the reader’s attention on general truths | Open 1 level above your specific field, no higher |
| Listing studies chronologically | Reads as an annotated bibliography, not an argument | Group sources by theme or by finding |
| Not clearly stating the gap | Reviewers cannot see why the study is needed | Use an explicit sentence naming what is missing |
| Overclaiming novelty | Invites rejection when a reviewer knows the field | Say “to our knowledge” and cite the nearest prior work |
| Mixing in results | Blurs the boundary between context and findings | Reserve all outcome data for the results section |
| Unsupported statistics | Undermines credibility immediately | Cite the registry, survey, or study behind each figure |
| Fake citations and hallucinations from using AI for drafting | Undermines credibility; journal editors and peer reviewers assume the entire paper is AI-generated and not real research | Verify all AI output before using it in your paper, especially AI-generated citations and references |
| Copying phrasing from sources | Risk of plagiarism even with a citation | Paraphrase fully and run a similarity check |
| Objectives that do not match the question | Signals a poorly planned study | Number questions and objectives in parallel |
Final Self-Review Checklist

- The funnel narrows steadily: no paragraph is broader than the one before it.
- The research gap appears in a single, quotable sentence.
- The research problem is stated in the present tense.
- The problem statement contains the ideal, the reality, the consequence, and the proposal.
- The primary research question is unambiguous and answerable with the planned data.
- The research hypothesis names both variables and is falsifiable.
- Research objectives begin with action verbs and align with the questions.
- Every numerical claim carries a citation.
- At least 60% of the citations are from the last 5 years, unless the field is historical.
- No results, no methods detail, and no conclusions have leaked into the section.
- The final paragraph states what the paper does, in 1 or 2 sentences.
- If you’ve used AI for literature search, writing, or editing, you’ve followed your journal’s policies and created a suitable disclosure statement.
Frequently Asked Questions
What is the difference between background and literature review in a research paper?
The background gives selective context and justifies 1 specific gap, usually within the introduction. The literature review critically synthesizes the broader body of evidence and often forms its own chapter. Backgrounds are narrative and directional; literature reviews are analytical and comparative.
How long should the background of the study be in a thesis?
For a master’s thesis, plan on 1,500-3,000 words; for a doctoral thesis, 3,000-5,000 words is common. The background typically occupies the first third of Chapter 1, with the problem statement, research questions, and objectives following it.
How do you write a background of the study for a quantitative research paper?
Move the background of a quantitative study through 5 stages: establish the topic’s importance, summarize established findings, present conflicting evidence, name the gap, and state the problem with your hypothesis and objectives. Quantitative backgrounds should define every variable operationally and cite the measurement instruments you plan to use.
Can a research paper have a background without a hypothesis?
Yes. Qualitative, exploratory, descriptive, and many mixed-methods studies replace the hypothesis with research questions or study aims. A hypothesis is expected when the design tests a predicted relationship between measurable variables, such as an experiment or a controlled trial.
How many references should the background section of a research paper include?
A journal article background usually cites 15-30 sources; a conference paper needs 8-15. Density matters more than count: aim for at least 1 citation per substantive claim, with 2-3 sources supporting any contested point.
What tense should be used in the background of a research paper?
Use present simple for established knowledge, past simple for the findings of individual studies, and present perfect for ongoing trends or debates. Describe your own study’s purpose in present simple, for example: this study evaluates.
How do you write a problem statement for a research paper with an example?
Follow the 4-part formula: describe the ideal situation, state the current reality with a citation, explain the consequence of the gap, then name what your study will do. Example: screening for X cancer should occur annually, yet only 28% of eligible women are screened, which delays diagnosis, so this study tests an SMS reminder in 4 clinics.
Should research objectives be included in the background of a research paper?
Yes, at the end. The standard order is: background context, research gap, problem statement, purpose, research questions, hypothesis if applicable, and then research objectives. Placing objectives last completes the funnel and tells the reader exactly what the paper delivers.
