But the problem with probability being square amplitude still bothers me. I will read Hugh Everitt's article again more carefully and see if I can figure out how he solves the problem. The non-linear nature of probability seems (to me) to be a problem. Consider a wave function which is the sum of two "worlds" w1 and w2. The non-linearity of probability seems to imply that the likelyhood of a given experimental outcome performed in w1 depends on w2: w1 and w2 are not really independent.
