I suppose you mean that another world is created for each eigenstate of the superposition. I've shown the fallacy of this interpretation in other discussions here, but haven't received a plausible reply. Specifically, since we're dealing with linear algebra, Hilbert spaces, there is no unique basis and therefore no unique superposition describing the same wf! So the worlds you claim to exist are over-determined. What worlds are you referring to? Which basis and eigenstates are you using, and why is that basis to be preferred?

By "ignorance" I am NOT asserting the existence of hidden variables. I merely prefer to say we don't know anything more than different probabilities for different possible outcomes. Why does this force anyone to assume hidden variables?
