Theories, models and analytical frameworks help us interpret global politics. Theories connect ideas about how politics works. Models deliberately simplify political relationships, while analytical frameworks provide categories or questions for examining evidence.

No single political theory is prescribed. Students need to draw on different perspectives instead of assuming that one explanation must be correct.

Diverse theoretical perspectives

The perspectives can overlap. One issue may simultaneously involve material power, international institutions, social norms, gender relations and colonial legacies.

Example: the South China Sea arbitration, 2016

The Philippines brought a case against China under the United Nations Convention on the Law of the Sea. The tribunal issued its award in 2016. From a liberal perspective, international law and arbitration offer ways to manage disputes. A realist reading instead emphasizes that China's material power and refusal to accept the award constrained enforcement.

A constructivist approach brings competing national identities and historical narratives into the analysis, since these affect what governments consider legitimate maritime entitlement. Each perspective directs attention towards a different form of power, but none fully explains the dispute on its own.

Example: Chile's constitutional process, 2019–2023

Mass protests began in Chile in 2019, challenging inequality and the legitimacy of existing institutions. The process produced two proposed constitutional texts; both were rejected in referendums in 2022 and 2023. Liberal analysis focuses on formal participation, elections and constitutional rules. Feminist analysis looks at the prominence of gender parity, along with debates over care and reproductive rights.

A postcolonial perspective draws attention to the constitutional recognition sought by Indigenous peoples and the longer history of authority over land and identity. Taken together, these approaches show why institutional reform concerned legal design as well as competing ideas about justice, representation and belonging.

Applicability describes how far a theory or model helps analysts understand a specific political issue in its particular context. A useful perspective highlights significant relationships and supports an evidence-based explanation. However, analysts should choose it to fit the issue rather than apply it mechanically.

How theories and models are used

Theories can help analysts:

• identify which actors, interests and forms of power need attention
• link individual events to broader political patterns
• compare similar issues at local, national, regional and global levels
• interpret evidence and assess competing claims
• build explanations that can be tested against real cases
• consider possible political responses.

Scale and context affect applicability. A state-centred theory may shed light on interstate military rivalry while missing the role of social movements. A gender framework may reveal unequal experiences hidden by aggregate economic or security models. Strong analysis may draw on several perspectives, provided their assumptions remain distinct.

Example: Russia's invasion of Ukraine, 2022

Realism applies clearly to Russia's full-scale invasion of Ukraine in 2022. It focuses attention on military capability, territorial control, alliance politics and the security calculations of Russia, Ukraine and NATO members. This helps explain why sovereignty and balances of power became central to state action.

Liberalism also applies because Ukraine relied on international institutions, legal claims and cooperation among supporting states. Constructivism extends the analysis by exploring rival narratives of nationhood, historical identity and legitimate statehood. From this perspective, ideas shaped actors' interests alongside material security.

Example: ASEAN's response to Myanmar, 2021

After Myanmar's military coup in 2021, the Association of Southeast Asian Nations adopted its Five-Point Consensus. It sought an end to violence, dialogue and regional mediation. Liberalism helps analysts assess whether a regional institution can coordinate pressure and manage a crisis through agreed procedures.

On its own, though, this perspective has limited applicability. Realism draws attention to ASEAN governments' concerns about sovereignty and regime security. Constructivism explains the influence of ASEAN's established norm of non-interference. Used together, these perspectives show why consensus did not automatically lead to implementation.

Choosing an appropriate perspective

A theory is most applicable when its central assumptions match important features of the case and evidence supports the relationships it proposes. Political analysis should ask what the theory reveals, which evidence it can organize and which politically significant factors remain outside its field of view.

Bias is a systematic tendency to privilege certain assumptions, evidence, actors or conclusions. Limitations mark the boundaries of what a theory or model can reliably explain or do.

A biased theory isn’t necessarily useless. Any theory selects some features of a complex world and treats them as more significant than others. The task is to identify those choices and assess their consequences.

What theoretical tools can do

Theories, models and frameworks can serve several connected functions:

• Organizing: arranging evidence around actors, institutions, interests, identities or power relationships.
• Evaluating: offering criteria for judging outcomes, such as security, legitimacy, equality or institutional effectiveness.
• Critically reviewing: challenging dominant explanations and revealing neglected assumptions or voices.
• Simplifying: reducing a complicated issue to its most significant relationships.
• Explaining: giving reasons for actors' motives and for the causes and consequences of political events.
• Predicting: identifying outcomes that may follow when the theory's assumptions and conditions hold.
• Prescribing: suggesting what political actors ought to do to achieve a desired outcome.

Doing one of these well doesn’t guarantee success in the others. A model might organize evidence clearly but predict badly. It may explain past decisions without offering an acceptable policy prescription.

Common sources of limitation

A theory may face limitations because it:

• treats states as unified actors while neglecting divisions within them
• prioritizes material power and underestimates norms or identity
• emphasizes institutions without sufficiently accounting for unequal enforcement power
• generalizes from experiences in one region or historical period
• overlooks gendered, racial or colonial power relationships
• simplifies actors' motives or assumes that they behave consistently
• relies on incomplete, contested or selectively chosen evidence.

Realists may argue that critical approaches understate hard security constraints. Liberals may respond that realism overlooks the independent effects of law, institutions and interdependence. Feminist and postcolonial scholars question both approaches when supposedly universal models marginalize gendered experiences or reproduce concepts derived from colonial centres of power. Constructivists challenge theories that treat interests as fixed rather than socially produced.

Example: Colombia's peace agreement, 2016

Colombia's 2016 peace agreement with the Revolutionary Armed Forces of Colombia showed the value of institutional models centred on negotiation, implementation and transitional justice. These models organize a highly complex conflict. They also help assess whether arrangements for political participation, accountability and reintegration support a more durable peace.

That simplification creates a limitation. A purely institutional account may understate rural inequality, illegal armed economies, local insecurity and the unequal experiences of women and Indigenous communities. Feminist and postcolonial perspectives critically review whose security and justice are being measured.

Example: Ethiopia's cessation of hostilities agreement, 2022

The 2022 agreement between Ethiopia's federal government and the Tigray People's Liberation Front can be read through a model of bargaining between organized political actors. This approach helps explain how military pressures, mediation and calculations about the costs of continued conflict opened space for an agreement.

Yet reducing the conflict to two negotiating sides risks excluding other affected communities. It may also oversimplify disputed identities, territorial claims and responsibility for violence. The case shows why prediction is difficult: an agreement may set out mechanisms for ending hostilities, but its longer-term consequences depend on implementation, legitimacy and political relationships that no single model can capture.

Evaluating success in real-world cases

A successful theoretical model makes key features of a case easier to understand and produces claims that fit the relevant evidence. Its limitations become serious when omitted factors alter the explanation, predictions depend on unrealistic assumptions, or prescriptions reflect the theorist's values without acknowledging them.

Strong analysis compares perspectives, tests each one against contextualized evidence and makes its own assumptions visible. Synthesis doesn’t require theories to agree. It combines their insights while preserving the tensions between their explanations and political priorities.
