In one world A happens. In the other world B happens. How does, for example, a 16:9 ratio get implemented. For example, A happens in 16 worlds and B in 9 worlds. Or in general, the proportion of worlds where A happens to worlds where B happens is 16/9.But it's an additional axiom that this is a probability measure and the split is per the Schroedinger amplitudes. Which then makes it just like Copenhagen. Note that that the odds ratio 16:9 depends on the interaction with measuring instruments (some other measurement would yield different odds) and so it depends on at what point you stop considering superpositions and say "That's classical enough. Let's just zero out the cross terms in the density matrix." Something Heisenberg or Born could have done and essentially what Bohr said. He realized that any measurement that people could agree on would have to be classical. So he held that the Heisenberg cut could be anywhere close enough to consciousness to be quasi-classical. BrentCould it be because the mind is identified with a classical computation while the brain is ultimately a quantum mechanical system?
Of course the brain is a quantum system, but as a computer it works like a classical computer (which is also a quantum system) for the very good evolutionary reason that it's survival depends on dealing with big, hot quasi-classical things like fruit and fish and tigers and other humans. If it gets a little bit of randomness from K40 decays or cosmic rays,...well a little bit of randomness can be useful, but not much.
