Manly and Wasserman on Extrinsic Dispositions in advance

Manley and Wasserman’s account of dispositions is that N is disposed to M when C if and only if N would M in some suitable proportion of C-cases, where a C-case is a fully specific scenario that settles everything causally relevant to the occurrence of M in a way that makes C obtain. Manley and Wasserman respond to some possible objections to their account by proposing that, in case of extrinsic dispositions, the closer the C-case is to actuality, the more it matters. In this paper, however, I will argue that their response fails.
