The challenge of finding appropriate tools for measurement validation is an abiding concern in political science. This article considers four traditions of validation, using examples from cross-national research on democracy: the levels-of-measurement approach, structural-equation modeling with latent variables, the pragmatic tradition, and the case-based method. Methodologists have sharply disputed the merits of alternative traditions. We encourage scholarsand certainly analysts of democracyto pay more attention to these disputes and to consider strengths and weaknesses in the validation tools they adopt. An online appendix summarizes the evaluation of six democracy data sets from the perspective of alternative approaches to validation. The overall goal is to open a new discussion of alternative validation strategies.
