Randomness is an empirical observation. Identically prepared quantum states, when measured, produce different experimental results, distributed probabilistically. MWI's solution to this is to say the experiments are wrong, and the results are actually the same. It rejects empiricism to simplify the theory. But that's not good science. > Neither of these universe are any more real or extant than the other (they have the same magnitude) What is meant by "magnitude?" It can't be the measure of the wavefunction because those can easily be different, e.g. if the particle's decay probability is not 50%. This is the Born rule problem again.
