You're big on point of view so you must know that if your doppelganger is experiencing a different city it in no way effects what you are seeing; so philosophically my low-tech experiment works just as well and is just as uninformative as your hi-tech version. > I give you a Island spath (CaCO_3 cristal), and I send a photon in some > polarized state, and if it deviates, I send you to Moscow, and if not, I > send you to Washington. > Then the calculation is easy and precise, the probability that I the Helsinki man will be in Moscow is 0% and the probability that I the Helsinki man will be in Washington is 0% because in any other city "I" would no longer be the Helsinki man. If you change the meaning of the personal pronoun "I" you can change the probability to 100% for both cities. But no matter what "I" means it will always be the case that the man who sees Moscow will be the Moscow man.
