Dr Eva Thomann to deliver seminar on Qualitative Comparative Analysis and Fuzzy Sets
On 3rd May Eva Thomann, Senior Lecturer in Politics at Exeter and a member of the Centre for European Governance, will deliver a seminar at the University of Reading on Qualitative Comparative Analysis and Fuzzy Sets.
What is QCA?
Social scientists often face a trade-off between identifying regularities among cases and accounting for the complexity of social reality. Achieving more “breadth” often comes at the cost of the “depth” of analysis. Qualitative Comparative Analysis (QCA) is a technique that combines elements of both. QCA enables a systematic, context-sensitive comparison of intermediate (ca. >10) up to large numbers of cases, which is enriched with in-depth case knowledge. As such it helps researchers to model several aspects of causal complexity, such as equifinality – meaning that many ways may lead to Rome – and the configurational nature of cases, for example intersectionality and contextually contingent patterns. Rather than focusing on isolated net effects, QCA if identifies necessary and sufficient conditions for an outcome. This makes it attractive for researchers interested in finding prerequisites for a given phenomenon, or the conditions under which outcomes (such as compliance, successful revolutions, democratic consolidation, etc.) come about.
