Section A: 15 5-Mark Exam Questions and Model Answers

Q1: What is the "organising question" of behavioural analysis, and what two commitments distinguish behaviouralists from other social scientists?

David Sanders identifies the organizing question of behavioural analysis as "Why do people behave in the way they do?" What separates behaviouralists from scholars in other traditions is not their substantive topic of study—which spans mass political participation, voting behavior, elite political leadership, interest group lobbying, and international relations—but rather two foundational methodological commitments. First, behaviouralists insist that observable behaviour at either the individual level (such as voters, citizens, and political leaders) or the aggregate level (such as political parties, interest groups, non-governmental organizations, and nation-states) must be the primary object of social inquiry. Sanders emphasizes that social science is fundamentally concerned with understanding what people "do, think or say." Second, behaviouralists require that any explanation offered for political behaviour must be susceptible to empirical testing against real-world observational data. This means that explanatory propositions cannot remain purely theoretical, normative, or interpretive; they must generate predictions that can be verified or falsified against empirical evidence. This dual insistence distinguishes behaviouralism from normative political theory, which evaluates how political institutions ought to operate, as well as from hermeneutic or interpretive approaches that focus on subjective human consciousness without requiring empirical testability. Ultimately, these two commitments establish behaviouralism's epistemological alignment with positivist philosophy and Karl Popper's principle of falsifiability.

Q2: Explain the positivist threefold classification of analytic statements.

Logical positivism, which developed out of the Vienna Circle in the 1920s and was popularized in the Anglophone world by Alfred Ayer and Carl Hempel, established a strict epistemological taxonomy known as the Positivist Threefold Classification. Under this framework, all meaningful analytic statements about the world fall into exactly three mutually exclusive categories. The first category comprises "useful tautologies"—statements that are purely definitional in nature and assign meaning to concepts without asserting any empirical fact about the world (for example, defining "below the poverty line" as earning less than one-third of the average national wage). The second category consists of "empirical statements"—substantive claims about observable reality that can be empirically tested against real-world observations to determine whether they are true or false. The third category encompasses "meaningless statements"—a catch-all classification into which strict positivists placed metaphysics, theology, aesthetics, and normative ethics. Positivists argued that because ethical or aesthetic claims cannot be empirically tested or logically proven, they are analytically devoid of cognitive meaning and constitute mere obfuscation. While modern behaviouralists inherited positivism's criteria for empirical theory and explanation, post-behaviouralists explicitly rejected the dogmatic dismissal of ethics, acknowledging that normative and hermeneutic traditions yield distinct, valid forms of knowledge while choosing to subject their own explanatory hypotheses
