Modeling configurational explanations

How can Qualitative Comparative Analysis contribute to causal knowledge? The article’s answer builds on the shift from design to models that the Structural Causal Model framework has compelled in the probabilistic analysis of causation. From this viewpoint, models refine the claim that ‘treatments’ have causal relevance as they specify the ‘covariates’ that make some units responsive. The article shows how QCA can be geared toward establishing configurational models of plausible ‘covariates.’ It explicates the rationale, operations, and criteria that confer explanatory import to configurational models, then illustrates how the basic structures of the SCM can widen the interpretability of configurational solutions and deepen the dialogue among techniques..
