Writing well in political science is not just about knowing supply and demand—it’s about mastering a discipline that blends rigorous empirical analysis with normative reasoning about how things should be. Political science papers must present evidence-based arguments, use precise terminology, and follow specific structural conventions that separate academic writing from casual commentary.

If you’re drafting a paper on democracy, analyzing international conflict, or exploring political theory, understanding these discipline-specific conventions can make the difference between a passing grade and top marks. This guide covers everything from choosing the right citation style to structuring your argument, with practical examples and common pitfalls to avoid.

What You Need to Know First: Four Subfields, Four Writing Styles

Political science is traditionally divided into four subfields, each with its own writing conventions:

Subfield Focus Writing Style Common Methods
American Politics U.S. institutions, voting behavior, public policy Quantitative, data-driven, similar to natural sciences Statistical analysis, surveys, experimental design
Comparative Politics Cross-national comparison of political systems Empirical, case-study driven, analytical Most-similar/most-different systems design, qualitative comparison
International Relations State interactions, global organizations, conflict Theoretical and empirical balance, case studies Game theory, conflict data analysis, treaty analysis
Political Theory Philosophical foundations, normative arguments Argumentative, textual interpretation, philosophical Close reading of canonical texts, normative argumentation

What this means for your writing: Your approach should change depending on your subfield. American Politics papers lean heavily toward quantitative analysis and statistical evidence. Comparative Politics relies on case studies and institutional analysis. International Relations blends theory with empirical testing. Political Theory demands careful textual interpretation and philosophical reasoning rather than data collection.

The key takeaway: adapt your writing to your subfield, not the other way around. Don’t write a descriptive essay when your comparative politics professor expects analytical comparison. Don’t use philosophical arguments when your American Politics class wants statistical evidence.

Essay Structure: The Political Science Blueprint

A strong political science paper follows a predictable structure that professors and reviewers expect. Deviating from this structure without clear justification can signal that you don’t understand the discipline.

Introduction: The Research Question and Thesis

Start with a precise research question or problem—not broad platitudes about “how important politics is in today’s world.” Your introduction should:

  1. Present the research question: What are you trying to answer? (e.g., “Does proportional representation lead to higher female representation in parliament?”)
  2. Explain significance: Why does this question matter? Connect it to existing scholarly debates.
  3. State your thesis: A clear, contestable claim that you will defend with evidence.

Good thesis examples:

  • Weak: “The UN is ineffective at maintaining peace.” (Too descriptive, not contestable)
  • Strong: “The UN is ineffective at preventing interstate conflict because its veto structure gives permanent Security Council members incentives to prioritize national interests over collective security, as demonstrated in cases in Syria, Ukraine, and Rwanda.”

Your thesis should be specific, use “because” to indicate reasoning, and be contestable—meaning reasonable scholars could disagree with you.

Main Body: Organized by Arguments, Not Cases

This is where most students make mistakes. Organize by argument, not by case study. Each paragraph should focus on one supporting point for your thesis.

The paragraph structure that works:

  • Topic sentence: Your main claim for this paragraph
  • Evidence: Data, case study detail, or theoretical citation
  • Analysis: Explain how this evidence supports your thesis
  • Connection: Link back to your overall argument

Common mistake: Students describe five countries in five paragraphs without synthesizing the evidence into a coherent argument. Don’t just list what happened in each country—explain why it matters for your thesis.

Conclusion: Synthesis, Not Summary

Your conclusion should:

  • Restate your thesis in light of the evidence presented
  • Synthesize your main arguments (don’t just repeat them)
  • Discuss broader implications for the field
  • Suggest directions for future research
  • Never introduce new information

Citation Styles in Political Science: APSA vs. Chicago vs. APA

Political science uses three primary citation styles, and choosing the wrong one can cost you points. Here’s how to decide:

APSA Style (American Political Science Association) — The Default Choice

APSA is a variation of Chicago style that’s the standard for most political science papers. Key features:

  • Uses parenthetical author-date citations: (Smith 2020, 10)
  • Does not use a comma between author and date
  • Does not use “p.” before page numbers
  • Reference list labeled “References,” not “Bibliography”
  • Strong guidelines for citing government documents, treaties, and legal sources

APSA example:

Smith's analysis of voting patterns demonstrates that turnout increased significantly after the Voting Rights Act (Smith 2020, 154).

Reference list entry:
Smith, John. 2020. The Voting Rights Act and American Politics. Princeton: Princeton University Press.

Chicago Manual of Style (Author-Date) — For Political History and Philosophy

Chicago is preferred for:

  • Political history
  • Political philosophy
  • Comprehensive research papers
  • Book publishing

Chicago uses similar parenthetical citations but also offers Notes-Bibliography (footnote) style, which APSA doesn’t use.

APA Style — For Policy and Quantitative Work

APA is used when:

  • Paper focuses on public policy
  • Heavy quantitative analysis
  • Behavioral studies
  • Some International Relations subfields

APA uses (Smith, 2020, p. 10) with the comma and “p.” format.

What to do: Always check with your professor, but if they don’t specify, use APSA. It’s the discipline standard and signals that you understand political science conventions.

See our Chicago Style Citation Guide for detailed formatting examples and examples of how Chicago style differs from APSA.

Writing Style: What Professors Expect

Political science writing has distinct characteristics that separate it from humanities essays or journalism:

Objectivity Over Subjectivity

Political science papers must be substantive, objective, and non-polemical. Avoid:

  • First-person pronouns (“I think,” “I believe”)
  • Colloquial language (“kids,” “big deal”)
  • Emotional appeals (“shocking,” “unfortunately”)
  • Unsupported generalizations

Instead, use:

  • Active voice (“The data show that…” not “It is believed that…”)
  • Precise terminology (“electoral participation” not “voting”)
  • Evidence-backed claims

Analytical Over Descriptive

This is the single biggest differentiator between good and poor political science writing. Don’t just describe what happened—explain why.

Descriptive (bad for political science):“France has a parliamentary system, Germany has a parliamentary system, and the United States has a presidential system.”

Analytical (good for political science):“France’s parliamentary system produces higher legislative gridlock than Germany’s because coalition governments in France are more fragile than those in Germany, as demonstrated by the average duration of coalition cabinets (France: 18 months; Germany: 36 months).”

The analytical version connects theory, evidence, and argument. It explains mechanisms, not just facts.

Clarity Over Complexity

Define key terms early:

  • “Democracy” (do you mean electoral democracy, deliberative democracy, or something else?)
  • “Power” (Are you discussing coercive power, structural power, or soft power?)
  • “Institution” (formal institutions? informal norms? or both?)

Vague terms undermine your argument. Be precise.

Types of Political Science Assignments

Different assignments require different approaches:

Research Paper

  • Analyzes literature to answer a research question
  • Requires theoretical framework and empirical evidence
  • Uses APSA or Chicago citation style
  • 15-25 pages typical

Response Paper

  • Critical analysis of a specific text or event
  • Shorter, focused on one argument
  • Emphasizes interpretation over data collection
  • 5-10 pages typical

Policy Memo

  • Concise memo outlining policy recommendations
  • Used in public administration and policy programs
  • Structured as: background, analysis, recommendations
  • 2-5 pages typical
  • Direct, actionable tone

Case Study

  • Detailed examination of a specific political phenomenon
  • Uses qualitative methods
  • Emphasizes mechanism tracing and causal inference
  • 10-15 pages typical

Literature Review

  • Synthesizes existing scholarship on a topic
  • Identifies gaps in the literature
  • Organized thematically or chronologically
  • Provides foundation for original research

Common Mistakes That Lower Your Grade

Mistake 1: Weak or Missing Thesis

Your thesis is the single most important element of your paper. Without a clear, contestable thesis, you have no argument to defend.

How to fix: Before drafting, write one sentence that answers: “What am I arguing, and why?” If you can’t answer this clearly, your thesis is weak.

Mistake 2: Descriptive Over Analytical

Describing events without explaining mechanisms or connecting to theory is the most common reason students get B-grades instead of A-grades.

How to fix: After every paragraph, ask: “What does this evidence show? What mechanism is at work?” If you’re just listing facts, you need more analysis.

Mistake 3: Ignoring Counterarguments

Good political science papers acknowledge opposing views and explain why your argument is stronger. Ignoring counterarguments signals that you haven’t thought deeply about the issue.

How to fix: Add at least one paragraph addressing the strongest counterargument to your thesis, then explain why your position is more convincing.

Mistake 4: Overrelying on One Source

Citing a single book or article as evidence for every claim makes your argument weak. Political science requires multiple sources from peer-reviewed journals.

How to fix: Use at least 5-10 peer-reviewed sources for a standard undergraduate paper. Mix quantitative studies, theoretical works, and case studies.

Mistake 5: Poor Citation Practices

Using MLA style when APSA is expected, or missing proper page numbers, signals carelessness. Proofreading is not optional in political science.

How to fix: Use a citation generator (see our Citation Generators Compared guide) and double-check every citation against APSA formatting rules.

Evidence Types in Political Science

Understanding what counts as valid evidence in political science is crucial:

Primary Evidence

  • Data sets (voting records, economic statistics, conflict data)
  • Treaties, official speeches, government documents
  • Survey results, polling data
  • Historical archives

Secondary Evidence

  • Peer-reviewed journal articles
  • Academic books and monographs
  • Think tank reports (with caveats about ideological bias)
  • Government publications and official statistics

What NOT to Use as Evidence

  • News articles (unless quoting official statements)
  • Personal opinions or anecdotes
  • Wikipedia
  • Blogs or opinion pieces
  • Unverified social media posts

Practical Checklist: Before You Submit

Use this checklist to verify your paper meets political science standards:

  • Thesis: Is it specific, contestable, and clearly stated in the introduction?
  • Structure: Is the paper organized by argument, not by case or chronology?
  • Analysis: Does every paragraph explain mechanisms, not just describe facts?
  • Evidence: Is every claim supported by peer-reviewed sources or data?
  • Counterarguments: Have you addressed the strongest opposing view?
  • Citation: Are you using APSA style (or as specified by your professor)?
  • Objectivity: Have you removed subjective language, colloquialisms, and unsupported generalizations?
  • Definition: Have you defined key terms early in the paper?
  • Proofreading: Have you checked for typos, grammatical errors, and citation formatting?

Making the Right Choice: When to Use Each Style

The most practical advice for political science students is simple: always ask your professor which citation style they prefer. If they don’t specify, default to APSA, as it’s the discipline standard.

When deciding which citation style to use, consider these rules:

Style Use When Avoid When
APSA Most political science papers, comparative politics, IR When professor specifies Chicago or APA
Chicago Political history, political philosophy, book publishing When professor specifies APSA
APA Quantitative work, public policy, behavioral studies When professor specifies APSA

The citation style doesn’t change your argument—it just changes how you format your sources. Choose carefully, follow the style guide precisely, and don’t mix styles.

Final Thoughts

Writing in political science requires balancing empirical rigor with theoretical depth. It’s not enough to describe what happens in politics—you need to explain why, using evidence that your professors can verify. The conventions of APSA citation, analytical over descriptive writing, and subfield-specific approaches are not arbitrary rules. They’re the standards that separate professional political science from casual commentary.

Mastering these conventions takes practice, but the payoff is significant. Papers that follow discipline-specific conventions earn higher grades, build stronger arguments, and prepare you for advanced graduate work in political science.
