can you tell me why the subjective probability of finding ourselves in a side of the split world, should be exactly proportional to the square of the thickness of that side?
Po’mi runs a trillion experiments, each of which have a one-trillionth 4D-thickness of saying B but is otherwise A. In his “mainline probability”, he sees the all trillion experiments coming up A. (If he ran a sextillion experiments he’d see about 1 come up B.)
Presumably an external four-dimensional observer sees it differently: He sees only one-trillionth of Po’mi coming up all-A, and the rest of Po’mi saw about 1 B and are huddled in a corner crying that the universe has no order. (Maybe the 4D observer would be unable to see Po’mi at all because Po’mi and all other inhabitants of the lawful “mainline probablity” that we’re talking about have almost infinitesimal thickness from the 4D observer’s point of view.)
If I were Po’mi, I would start looking for a fifth dimension.
