There is something that makes me feel confused about MWI. Maybe it is its reliance on anthropic principle (probability of finding myself in a world where recorded history have probability P (according to Born’s rule) must be equal to P). This condition depends on every existing universe, not just on ours. Thus it seems that to justify Born’s rule we should leave observable evidence behind and trail along after unprovable philosophical ideas.
