So how does the MWI deal with a measurement with a 3/4 probability of outcome 1 and a 1/4 probability of outcome 2? This was Larry Niven's objection to many worlds back around the time he wrote "All the myriad ways" and it seems to me that someone else would have noticed it in the intervening 50 years (or whatever) ! How come anyone takes MWI seriously if it's actually supposed to work like this? > The classical duplication model of step 3 cannot reproduce quantum > probabilities because it relies on branch counting. Well that's OK because it isn't attempting to reproduce quantum probabilities at that point, as far as I know. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
