That's well and good, but "prediction" is an attribute of a representative model, not of reality. Reality doesn't represent or predict itself; it just occurs. T

That's well and good, but "prediction" is an attribute of a representative model, not of reality. Reality doesn't represent or predict itself; it just occurs. The problem of comparing against "hidden variable theories" in this context is that the variables wouldn't be hidden to reality; they'd only be hidden to us. So can we predict better than QM? Maybe not. Does QM describe the truth behind experience? Probably not, and it isn't meant to.
