Abstract

Epistemological positioning is foundational to any analysis, yet pluralist epistemologies are taught unevenly in political science methods courses. This article draws attention to this crucial foundation and suggests that a basic grounding in positivist and interpretivist research paradigms would give students conceptual tools to adjudicate between competing claims and contradictory evidence in the empirical world—even as it would highlight comparative advantages of different approaches to knowledge production. Using an optical illusion as a heuristic guide, the article proposes a practical classroom exercise to illustrate the central differences between positivist and interpretivist approaches to political science and to elucidate how these differences play out in research design and inquiry.
