 It’s no accident that the messy shopper example has both an ignorance thread and a difference thread. Typically, where there’s an argument from ignorance, there’s an argument from difference—the pre- and post-discovery stages in a case of resolved ignorance will be importantly doxastically different. And even when the ignorance isn’t resolved, there will be in the background a relevant doxastic difference between the subject in the case as described and the subject as they would be if the ignorance were resolved.
