All it requires is denying there is magic involved in the first-person view. If someone created a duplicate of you in Andromeda, there would be no way for you here on Earth to know about that view because there's no interaction between your brain on Earth and your Brain in Andromeda. Similarly, there's no interaction between your brain that's seen and formed memories of measuring the up-spin electron and the one that's seen and formed memories of measuring the down-spin electron. So unless you're operating according to a philosophy of mind that allows it to violate physics and learn/know about the other one, then there is no way to avoid the selection or indeterminacy about which one you will later subjectively identify with. > The formalism merely says that an initial state evolves into a > superposition -- nothing is selected as a "person" in that superposition > that could self-select, or be an indeterminate individual. You seem to be ignoring/eliminating/denying the existence of the first-person perspectives create by the brains that enter states of superposition. > MWI does not lead to a useful notion of probability that can be used, via > the Born rule, to infer that interference terms are not important. > I don't understand the above sentence.
