This talk explores the steps that need to be taken to build a causal model for EPR experiments. Wood and Spekkens (2015) argued that causal discovery algorithms are insufficient for this task: they cannot distinguish EPR from Bell-inequality-violating correlations, since both share the same independence relations. Bell inequality violations instead provide a hypothesis space of possible causal models. I argue that selecting from this space requires a commitment to both an interpretation of quantum mechanics and a theory of causation. I further argue that even these commitments may not select a unique causal model, since different adequacy criteria for causal arrows can yield competing models within the same physical theory, as I illustrate using de Broglie-Bohm theory.
