15 Common Mistakes When Studying Political Science (And How to Fix Them) | LearnByTeaching.ai
Political science requires analyzing power, institutions, and governance with scholarly rigor while engaging with topics that provoke strong personal opinions. The central challenge is separating empirical analysis from normative beliefs, and most student mistakes stem from failing to make that distinction consistently.
Substituting personal opinions for analytical arguments
Students write essays that argue from personal political beliefs rather than building evidence-based analytical arguments. Political science requires analyzing how systems work, not advocating for how they should work (unless explicitly doing normative theory).
Asked to analyze why voter turnout is low in the US, a student writes a persuasive essay about why people should vote rather than examining structural factors (registration barriers, Electoral College, first-past-the-post) that empirically depress turnout.
How to fix it
Before writing any analysis, ask: am I describing how things are or how I think they should be? Use evidence and theoretical frameworks to build your argument. State assumptions explicitly. You can have opinions, but academic political science requires you to support claims with data and theory.
Confusing empirical and normative claims
Students mix up 'is' statements (empirical, testable) with 'ought' statements (normative, value-based) in their analysis. Political science deals with both, but conflating them undermines analytical rigor.
A student writes 'proportional representation is better than first-past-the-post' as an empirical claim. This is normative — 'better' depends on values. The empirical claim would be 'proportional representation produces more parties and higher descriptive representation than FPTP.'
How to fix it
Practice identifying whether each claim in your writing is empirical or normative. Empirical claims can be tested with data; normative claims depend on values. Both are valid in political science, but they must be clearly distinguished and handled with appropriate methods.
Not understanding how electoral systems shape outcomes
Students memorize the names of electoral systems without understanding the mechanical effects that Duverger's law and its extensions predict: how the voting rules shape party systems, representation, and governance.
A student cannot explain why the US has two major parties while Germany has many, because they learned that the US uses FPTP and Germany uses mixed-member proportional but never connected the electoral rules to the party system outcomes.
How to fix it
Study the causal mechanisms: FPTP creates winner-take-all dynamics that punish third parties (Duverger's law). Proportional systems lower the threshold for representation, enabling more parties. Work through specific country examples to see these mechanisms in action.
Ignoring comparative politics perspectives
Students studying American politics treat the US system as the default rather than as one case among many. Without comparative context, they cannot identify which features are uniquely American and which are universal to democracies.
A student assumes that presidential systems, judicial review, and federalism are standard features of democracy, not realizing that most democracies are parliamentary, many lack strong judicial review, and unitary systems are more common than federal ones.
How to fix it
For every American political institution, identify how other democracies handle the same function differently. Compare the US presidential system with UK parliamentary government, German federalism, and French semi-presidentialism. This comparative lens transforms your understanding of both American and global politics.
Oversimplifying rational choice models
Students either accept rational choice theory uncritically (assuming all political behavior is pure self-interest) or reject it entirely (because people obviously don't always act rationally). Both positions miss the point — rational choice models are simplifying tools, not literal descriptions.
A student dismisses the median voter theorem because 'voters don't really calculate the ideal candidate position,' not understanding that the theorem models tendencies in aggregate behavior, not individual psychology.
How to fix it
Treat rational choice models as analytical tools: they make simplifying assumptions to generate testable predictions. Evaluate them by whether the predictions hold empirically, not by whether the assumptions are literally true. Understand their strengths (parsimony, testability) and limitations (ignoring identity, norms, emotions).
Writing descriptive papers instead of analytical ones
Students describe political events, institutions, or policies in detail without analyzing why they exist, how they function, or what causes them to change. Description is necessary but insufficient for political science.
Asked to write about the European Union's democratic deficit, a student describes the EU's institutional structure (Commission, Parliament, Council) in detail but never analyzes why scholars consider it democratically deficient or evaluates proposed reforms.
How to fix it
Every paper should have an analytical argument, not just a description. Ask yourself: what is my thesis? What am I explaining? Use the 'so what?' test — if your reader could respond 'so what?' to your paper, you need a stronger analytical framework.
Not engaging with quantitative methods
Political science increasingly relies on statistical analysis, causal inference, and data-driven research. Students who avoid the quantitative side limit their ability to read current research and conduct their own.
A student cannot interpret a regression table in a political science journal article, missing the key findings because they skipped the methods course and only read qualitative studies.
How to fix it
Take at least one quantitative methods course. Learn to read regression output, understand p-values and confidence intervals, and recognize the difference between correlation and causation. Work with real political data — election results, polling data, legislative voting records — using R or Stata.
Treating political theory texts as opinion pieces
Students read Hobbes, Locke, Rawls, and other theorists as if they were writing op-eds rather than constructing carefully reasoned philosophical arguments. This leads to surface-level engagement and missed logical structure.
A student summarizes Rawls' veil of ignorance as 'he thinks we should be fair to everyone' without understanding the logical argument: that rational agents choosing principles of justice without knowing their position in society would choose principles protecting the worst-off.
How to fix it
Read political theory slowly, identifying the premises, logical steps, and conclusions of each argument. Ask: what is the starting assumption? What follows from it? Where could the argument be challenged? Engage with the logic, not just the conclusion.
Confusing the Constitution's text with its interpretation
Students treat the US Constitution as a fixed, clear document rather than as a text whose meaning has been continuously contested and reinterpreted through judicial review, political practice, and amendment.
A student argues about what the Second Amendment 'means' based only on the text, without recognizing that the Supreme Court's interpretation has evolved dramatically from Miller (1939) to Heller (2008) to Bruen (2022).
How to fix it
Study constitutional development as an evolving process. Learn how key Supreme Court decisions have reinterpreted constitutional provisions over time. Understand the major interpretive frameworks: originalism, living constitutionalism, textualism, and purposivism.
Only following news from one political perspective
Students consume political news from sources that confirm their existing views, limiting their ability to understand opposing perspectives analytically. Political science requires understanding all sides of a debate, not just your own.
A student cannot explain the strongest arguments for a policy position they disagree with, because they only read sources that criticize it. On an exam asking for a balanced analysis, they produce a one-sided argument.
How to fix it
Read quality sources across the political spectrum. Practice steel-manning: articulate the strongest version of arguments you disagree with. Follow current events through analytical sources (The Economist, Foreign Affairs, Brookings, CATO) rather than purely partisan ones.
Not connecting theory to current events
Students study political theories and frameworks in the abstract without applying them to contemporary events, missing the opportunity to test their understanding and make the material memorable.
A student memorizes the definition of authoritarian backsliding for an exam but never applies the concept to analyze current political developments in countries where democratic norms are being eroded.
How to fix it
After each lecture, find a current event that illustrates the concept you just learned. Apply the theoretical framework explicitly: does Putnam's social capital theory explain declining civic participation in your community? Does the selectorate theory predict the foreign policy behavior of a specific regime?
Writing policy memos without evidence
Students write policy recommendations based on intuition rather than evidence. Effective policy memos require data, cost-benefit analysis, and consideration of implementation challenges and unintended consequences.
A student writes a policy memo recommending universal basic income as a solution to poverty but includes no data on costs, pilot program results, labor market effects, or political feasibility — just the argument that it 'makes sense.'
How to fix it
Follow a structured policy memo format: define the problem with data, present options with evidence for and against each, analyze costs and feasibility, and recommend with caveats. Every claim should be supported by evidence from research, pilot programs, or comparative cases.
Ignoring the role of institutions
Students focus on individual politicians and events while underestimating how institutional rules, norms, and structures shape political outcomes. Institutional analysis is central to political science but feels less exciting than personality-driven narratives.
A student explains a policy outcome entirely by the preferences of the president, without considering how the committee system in Congress, the filibuster in the Senate, and the structure of federal agencies constrained or enabled the outcome.
How to fix it
For every political outcome, identify the institutional context: what rules governed the process? What veto points existed? How did institutional incentives shape actor behavior? Practice analyzing the same event from an institutional perspective versus a personality-driven one.
Procrastinating on research papers until the last week
Political science papers require finding scholarly sources, developing an argument, and revising multiple drafts. Students who start late produce descriptive summaries rather than analytical arguments because they lack time for the iterative writing process.
A student starts a 15-page comparative politics paper five days before the deadline, finds three sources, and produces a descriptive overview of two countries rather than an analytical comparison testing a specific theoretical claim.
How to fix it
Break research papers into weekly milestones: topic selection and initial sources (week 1), thesis development and outline (week 2), first draft (week 3), revision and final draft (week 4). The analytical quality that distinguishes an A paper from a C paper requires revision time that procrastination eliminates.
Not reading primary sources
Students rely on textbook summaries of foundational texts (Federalist Papers, Tocqueville, Putnam) rather than reading the originals. Summaries lose the nuance and argumentation that make these works important.
A student quotes Federalist No. 10 from a textbook summary about factions but has never read the actual text and cannot engage with Madison's specific argument about the advantages of a large republic in controlling faction.
How to fix it
Read the key primary sources assigned in your courses. For American politics, read at least Federalist 10 and 51 in full. For political theory, read the assigned excerpts of Hobbes, Locke, and Rawls rather than just summaries. The reasoning matters more than the conclusion.
Quick Self-Check
- Can you distinguish between an empirical claim and a normative claim in your own writing?
- Can you explain how first-past-the-post electoral rules mechanically produce a two-party system?
- Can you articulate the strongest version of a political argument you personally disagree with?
- Can you read a regression table in a political science journal article and interpret the key findings?
- Can you identify the analytical argument (not just the topic) in your most recent paper?
Pro Tips
- ✓Practice the 'steel man' exercise regularly: articulate the strongest possible version of arguments you disagree with. This is the core skill of analytical political science.
- ✓Apply every theoretical framework you learn to a current event within 24 hours — this makes abstract concepts concrete and tests your understanding.
- ✓Read across the political spectrum from analytical sources, not just partisan ones; understanding all perspectives is a professional requirement in political science.
- ✓When writing papers, state your thesis as a testable claim in the first paragraph. If your thesis cannot be wrong, it is not an argument — it is a description.
- ✓Take quantitative methods seriously even if you prefer qualitative research; the ability to read and interpret statistical evidence is now expected in every subfield.
