 This apparent counterexample can be resisted, however. The only relevant disposition possessed by Shoemaker’s key, it might be insisted, is the disposition to open locks of a certain type—the type of lock that is currently on Shoemaker’s front door. Since a change in the lock will not cause the key to lose this disposition, it is an intrinsic disposition—or at least the present example does not show that it is not intrinsic. According to this response, the predicate ‘disposed to open Shoemaker’s front door’ either fails to express a genuine property at all—this is Shoemaker’s view—or else it somehow manages to express the intrinsic disposition to open locks of a certain type (Molnar 2003). McKitrick (2003a), however, argues that this response fails. She goes further to argue that there are indeed many cases of extrinsic dispositions, listing as examples weight (a case borrowed from Yablo 1999), vulnerability, visibility and recognizability. In light of these examples, it seems hard to dismiss the counterexamples to IDT as concerning spurious dispositions.
