A popular strategy for resolving Kim's exclusion problem is to suggest that mental and physical property tropes are identical despite the non-identity of the mental and physical properties themselves. I argue that mental and physical tropes can be identified without losing the dispositional character of mentality only if a dual-character hypothesis regarding the intrinsic characters of tropes is endorsed. But even with this assumption, the causal efficacy of the wrong dispositions is secured.
