Assessing the Trivialness, Relevance, and Relative Importance of Necessary or Sufficient Conditions in Social Science

Political scientists of all stripes have proposed numerous necessary or sufficient condition hypotheses. For methodologists a question is how can we assess the importance of these necessary conditions. This article addresses three central questions about the importance of necessary of sufficient conditions. The first concerns de “trivialness” of necessary or sufficient conditions. The second is how much a necessary or sufficient condition is “relevant?” The third important question deals with the relative importance of necessary or sufficient conditions: for example, ifX1 andX2 are necessary or sufficient conditions, is one more important than the other? The article develops measures to assess the importance of necessary or sufficient conditions in three related contexts: (1) Venn diagram, (2) 2×2 tables, and (3) fuzzy sets. Two empirical examples are discussed at length: (1) Skocpol’sStates and Social Revolutions: A Comparative Analysis of France, Russia, and China and (2) Ragin’s (2000) analysis of the cause of IMF riots.
