Nick: presumably in same way it would... but I don't really see how. Remember, this is indexical uncertainty. It doesn't correspond to uncertainty about what actually happened so much as uncertainty about which branch of reality this version of you is in.

So... There's a version of you in A, and a version of you in B.

In A, all the computations that happen are more or less analogous to those in B, except that B uses slightly larger numbers to represent the computations...

So exactly why would that change any anticipation of anything? I'd be unsure what a nonconscious Bayesian decision system would be computing/anticipating, unless the Born rule was already hard coded into it.

Yes, presumably there's _some_ actual physical reason which gives rise to the Born statistics, and once we know that, that may even help us talk about it better. But right now, I don't really even see any obvious way to state the rule without invoking anticipation of experience.

Since both branch A and B are real... what exactly are we weighing other than something along the lines of "where is more of our consciousnes experience flowing?"

And it's really annoying to have to phrase it like that. I know I'm confused on this. But right now, I don't see any obvious way to state the rule without saying something to that effect.
