15 Common Mistakes When Studying International Relations (And How to Fix Them) | LearnByTeaching.ai
International relations demands that students juggle competing theoretical paradigms, apply them to real-world events in flux, and write with both analytical rigor and policy relevance. The most common mistakes stem from oversimplified thinking, theoretical dogmatism, and a failure to connect academic frameworks to messy geopolitical reality.
Defaulting to a single theoretical paradigm for every question
Students pick a favorite theory (usually realism) and apply it to every situation, ignoring that different paradigms illuminate different aspects of international politics. This produces one-dimensional analysis.
A student explains the creation of the European Union using only realist logic (states balancing against threats), missing the liberal institutionalist explanation (cooperation through institutions reduces transaction costs) and the constructivist account (shared European identity formed through decades of interaction).
How to fix it
For every event or case study, practice applying at least three theoretical lenses: realism, liberalism, and constructivism. Ask: what does each theory predict? Which predictions match the evidence? The best analysis often synthesizes insights from multiple paradigms rather than dogmatically applying one.
Confusing descriptive and prescriptive analysis
Students blur the line between describing how the world works (positive analysis) and arguing how it should work (normative analysis). Academic IR requires both, but conflating them weakens arguments.
A student writes that 'states should cooperate more on climate change because cooperation is good' — this is purely normative. An analytical paper would examine why cooperation is difficult (collective action problems, free-riding), under what conditions it succeeds, and which institutional designs promote it.
How to fix it
In academic writing, clearly separate what is from what ought to be. Start with descriptive analysis: what's happening and why? What do the theories predict? Then, if appropriate, offer prescriptive conclusions grounded in your analysis. The descriptive work should always come first and be the bulk of your paper.
Not understanding the security dilemma
The security dilemma — where one state's defensive measures make other states less secure, triggering arms races — is central to IR but widely misunderstood. Students often treat it as simple 'countries distrust each other' instead of a structural problem.
A student describes the U.S.-China military competition as 'both sides being aggressive,' missing the security dilemma's core insight: even defensive military buildups by one side are perceived as offensive threats by the other, making conflict more likely even when neither side wants war.
How to fix it
Study the security dilemma as a structural problem, not a behavioral one. The key insight is that under anarchy (no world government), states can't be certain about each other's intentions, so even genuinely defensive actions can trigger escalation. Understanding this explains arms races, alliance formation, and the difficulty of disarmament.
Treating international institutions as either all-powerful or irrelevant
Students either idealize the UN and international law as solutions to global problems or dismiss them as powerless facades. Both extremes miss the nuanced reality of how institutions shape state behavior.
A student argues that the UN Security Council is useless because it couldn't prevent the Iraq War, ignoring that international institutions constrain behavior in less dramatic ways — shaping norms, providing information, reducing transaction costs, and creating forums for negotiation that prevent countless smaller conflicts.
How to fix it
Study what institutions actually do rather than what their charters promise. International institutions are neither world government nor decoration — they reduce uncertainty, provide focal points for coordination, and create reputational costs for defection. Learn specific mechanisms: how does the WTO dispute resolution system work? How do UN peacekeeping missions affect conflict duration?
Writing essays that summarize instead of analyze
Students retell events or summarize readings without providing analytical arguments. IR essays should use evidence to support a thesis, not narrate history.
A student writes a paper on the Cuban Missile Crisis that provides a detailed timeline of events but never argues why the crisis ended peacefully — missing the opportunity to apply theories of deterrence, crisis bargaining, or rational choice to explain the outcome.
How to fix it
Start every essay with a clear thesis statement that makes an analytical argument. Each paragraph should present evidence that supports or qualifies your argument, not just describe what happened. The test: could a reasonable person disagree with your thesis? If not, it's a summary, not an argument.
Ignoring international political economy
Students focus on security issues (war, alliances, nuclear weapons) and neglect economic dimensions of IR: trade, monetary relations, development, and sanctions. Modern global politics is as much about economics as security.
A student analyzes U.S.-China relations purely through a military lens, ignoring the trade war, technology competition, supply chain dependencies, and financial interdependence that are equally or more important in shaping the relationship.
How to fix it
Study international political economy alongside security studies. Understand comparative advantage and trade theory, how sanctions work (and when they don't), why currency manipulation is a political issue, and how economic interdependence can both promote peace and create vulnerabilities. Every security issue has an economic dimension.
Not following current events and connecting them to theory
IR is a living discipline where theory meets current reality. Students who only study historical cases can't apply their knowledge to contemporary questions, which is the whole point.
A student can analyze the Cold War in detail but can't apply deterrence theory to the current Taiwan Strait situation, or balance-of-power theory to current Middle Eastern geopolitics, because they haven't followed recent developments.
How to fix it
Read international news daily from multiple sources (Foreign Affairs, The Economist, Al Jazeera, BBC World). For each major event, ask: which IR theory best explains this? What would realists predict happens next? What would liberals predict? What would constructivists emphasize? This practice is the bridge between academic theory and the real world.
Misunderstanding what 'anarchy' means in IR theory
In IR, anarchy doesn't mean chaos — it means the absence of a central authority above states. This structural condition is the starting point for realist and liberal theories but is often confused with disorder.
A student writes 'because the international system is anarchic, states are constantly at war,' confusing anarchy (no world government) with chaos. Under anarchy, states may cooperate, trade, form alliances, and create institutions — they just do so without an overarching authority to enforce agreements.
How to fix it
Understand anarchy as a structural condition: there is no authority above sovereign states that can enforce rules or settle disputes with binding power. This means states must rely on self-help, but it doesn't mean cooperation is impossible. Realists emphasize the constraints of anarchy; liberals show how institutions and interdependence can mitigate its effects.
Confusing levels of analysis
IR explanations operate at three levels: individual (leaders' decisions), state/domestic (regime type, bureaucratic politics), and systemic (international structure). Mixing these levels without clarity produces muddled analysis.
A student argues that the Iraq War happened because 'the international system was unipolar' (systemic) and 'Bush wanted revenge for 9/11' (individual) in the same paragraph without distinguishing between the structural permissive cause and the individual-level proximate cause.
How to fix it
When analyzing any event, explicitly identify which level of analysis you're using. A complete analysis often incorporates all three levels: the systemic level explains why something was possible, the state level explains domestic motivations, and the individual level explains specific decisions. Label your levels clearly in your writing.
Not reading primary sources and foundational texts
Students rely on textbook summaries of Thucydides, Morgenthau, Waltz, Keohane, and Wendt without reading the originals. Textbook summaries simplify nuanced arguments into caricatures.
A student describes Waltz's structural realism as 'states just want power' because that's how the textbook summarized it, missing Waltz's actual argument that systemic structure constrains state behavior regardless of leaders' motivations — a much more sophisticated claim.
How to fix it
Read the foundational texts in their original form, even if selectively. Key chapters from Waltz's Theory of International Politics, Keohane's After Hegemony, and Wendt's Social Theory of International Politics are essential. The nuances in these works are what separate strong analysis from textbook-level understanding.
Assuming rationality means states always make 'good' decisions
Rational choice theory in IR assumes states are purposive actors pursuing goals, not that they always make optimal decisions. Students confuse rationality with omniscience or good outcomes.
A student argues that the decision to invade Iraq proves states aren't rational actors, confusing rationality (acting purposively toward goals given available information) with omniscience (knowing all consequences in advance).
How to fix it
Understand that 'rational' in IR means having consistent preferences and choosing actions believed to achieve them. Rational actors can make terrible decisions based on bad information, miscalculation, or domestic political pressures. Rationality is an assumption that helps build models, not a claim that every state decision works out well.
Neglecting non-state actors
Traditional IR focuses on states, but students who ignore international organizations, NGOs, multinational corporations, terrorist networks, and transnational movements miss major forces in contemporary global politics.
A student analyzes Middle Eastern politics focusing only on state governments, ignoring the significant roles of Hezbollah (non-state armed group), OPEC (international organization), major oil companies (MNCs), and refugee movements (transnational issue) in shaping regional dynamics.
How to fix it
When analyzing any issue, ask: which non-state actors matter here? Include international organizations, NGOs, MNCs, armed non-state groups, diaspora communities, and transnational advocacy networks. The degree to which non-state actors matter is itself a theoretical question — realists downplay them, liberals and constructivists give them more weight.
Writing policy papers without actionable recommendations
Students make vague recommendations ('the international community should do more') instead of specific, feasible policy proposals with clear mechanisms, actors, and trade-offs identified.
A student's policy paper on climate change concludes with 'countries need to cooperate more to reduce emissions,' without specifying which institutional mechanism (carbon tax, cap-and-trade, technology transfer), which actors need to act, what incentives would drive compliance, and what the political obstacles are.
How to fix it
Policy recommendations should be specific, feasible, and address trade-offs. Name the actor who should act, the mechanism they should use, why this is politically feasible, what the costs are, and who would oppose it. 'The U.S. should offer technology transfer agreements to India and China in exchange for binding emissions targets, enforced through WTO trade mechanisms' is a recommendation. 'We need more cooperation' is not.
Not studying historical case studies in depth
Students learn many cases superficially rather than a few cases deeply. In-depth case knowledge is what allows you to test theoretical predictions against empirical reality.
A student mentions the Cuban Missile Crisis in every paper but only knows the basic timeline, missing the internal decision-making processes (ExComm deliberations), the back-channel communications, and the Turkish missile trade that are essential for understanding why deterrence worked in this case.
How to fix it
Choose 5-8 major case studies and learn them in depth: the Cuban Missile Crisis, Rwandan genocide, EU integration, the end of the Cold War, the Iraq War, the Paris Climate Agreement, and 1-2 current crises. Deep knowledge of a few cases is far more valuable analytically than shallow knowledge of many.
Not engaging with quantitative IR research
IR increasingly uses statistical methods to test hypotheses about conflict, trade, and institutions. Students who only read qualitative work miss important findings and limit their analytical toolkit.
A student claims that 'democracies never fight each other' as established fact without engaging with the quantitative democratic peace literature, which shows the relationship is robust between democracies but contested in its causal mechanisms and subject to important caveats about how 'democracy' and 'war' are defined.
How to fix it
Read quantitative IR research, at least enough to understand the findings and their limitations. You don't need to run regressions yourself, but you should understand what statistical significance means, how selection effects work, and why correlation isn't causation. The Journal of Conflict Resolution and International Organization publish accessible quantitative work.
Quick Self-Check
- Can you explain the same international event through realist, liberal, and constructivist lenses and identify what each theory gets right and wrong?
- Do you understand the security dilemma as a structural problem, not just distrust between countries?
- Can you write an essay with a clear analytical thesis rather than just summarizing events?
- Do you follow current international events and practice applying theoretical frameworks to them?
- Can you distinguish between systemic, state-level, and individual-level explanations and use all three in your analysis?
Pro Tips
- ✓Read Foreign Affairs, The Economist's international section, and at least one non-Western news source weekly; applying theory to current events in real time is the most effective way to internalize theoretical frameworks.
- ✓When writing essays, structure your argument around a theoretical debate rather than a chronological narrative — 'Realists predict X but the evidence shows Y, which supports the liberal argument that Z' is far stronger than a timeline of events.
- ✓Study the Cuban Missile Crisis in extreme depth — it illustrates deterrence theory, crisis bargaining, bureaucratic politics, individual decision-making, and the security dilemma all in one case, making it the single most useful case study in IR.
- ✓Practice writing one-page policy memos that identify a problem, analyze its causes through an IR theoretical lens, and propose a specific, feasible policy response with trade-offs identified — this format is what employers in foreign policy actually want.
- ✓Engage with perspectives from the Global South — Amitav Acharya, Mohammed Ayoob, and other scholars challenge Western-centric IR theories and provide essential perspectives for understanding global politics beyond the great power framework.
