Wow! Sounds lot like the trickery done in Permutation City to
confirm the "dust hypothesis". Of course, in that universe the
backtracking would cause a branching all the time of slightly different
individuals in parallel worlds.
It is not unreasonable to think that similar unrolling happens in
our minds. We already know that consciousness seems to be backdating
itself (the experiments of Libet et al), and I assume Dennets
draft model of consciousness also might include this. We might contain
lots of "attempted persons", and only one becomes actual.
