And Bell knew of course that his inequality was not consistent with Quantum Mechanics, what he didn't know at the time was if his inequality was consistent with reality or if Quantum Mechanics was. That question was answered experimentally a couple of decades after Bell's theoretical work and the winner was Quantum Mechanics; so now we know that at least one of the assumptions that Bell made (realism, locality, high school math works) must be wrong. > but Bell's inequality IS violated. >> > > Experimentally, > Huh?

MWI is not local so it could be correct, and emotionally it is my favorite interpretation, but logically I must admit that it is not the only interpretation that could be correct. Much as I dislike Copenhagen the fact is it's non-realistic so the violation of Bell's inequality is not rule it out. But Einstein's idea that things are realistic and local (and deterministic too although determinism was less important to Einstein than realism or locality) IS ruled out.
