For simulations, some people think it’s possible to know. The argument is based on anthropics. The Quantum Physics Sequence might make you more certain of the MWI, but I haven’t read it. You could also base your probability of MWI on Occam’s Razor somewhat, since it seems to be the simpler interpretation.
