He says that the argument given for many-worlds is valid iff you’re a scientific realist, which not all scientists are.
Even then it’s not obvious that it’s the best explanation. Also depends on what you mean by ‘realist’.
Apparently Solvent’s friend thinks otherwise. My own physics-grad-student friend said MWI looks like the best explanation, though he stressed our ignorance more.
Well, another approach is to decide that probability distributions are merely a classical approximation to density matrices.
