Is democratization good for peace? The question of whether democratization results in violence has led to a spirited and productive debate in empirical conflict studies over the past two decades. The debate, sparked by Mansfield and Snyder’s foundational work, raised a challenge to the notion of a universal democratic peace and elicited numerous critical responses within the literature. One set of such responses has emphasized issues of replicability, mismatches between the research design and directionality of the proposed causal mechanism, the role of outliers, and model specification. In addition, two issues have not been discussed sufficiently in the existing literature. First, conceptually, is the issue of concept stretching, specifically the form Sartori labeled the “cat-dog” problem. While past criticisms were mainly about model specification, we debate whether Mansfield and Snyder’s findings can be seen as a product of concept misformation. Second, quantitatively, are conceptual and empirical issues that Mansfield and Snyder use to capture state strength in their most recent attempts to provide ongoing evidence for their theory. The most optimistic estimates show that even when democratization has a statistically significant association with war onset at lower levels of institutional strength, the effect is substantively insignificant.
