If a future decision is to shape the present, we need to predict it.
The decision-theoretic strategy “Figure out where you are, then act accordingly.” is merely an approximation to “Use the policy that leads to the multiverse you prefer.”. You *can* bring your present loyalties with you behind the veil, it might just start to feel farcically Goodhartish at some point.
There are of course no probabilities of being born into one position or another, there are only various avatars through which your decisions affect the multiverse. The closest thing to probabilities you’ll find is how much leverage each avatar offers: The least wrong probabilistic anthropics translates “the effect of your decisions through avatar A is twice as important as through avatar B” into “you are twice as likely to be A as B”.
So if we need probabilities of being born early vs. late, we can compare their leverage. We find:
Quantum physics shows that the timeline splits a bazillion times a second. So each second, you become a bazillion yous, but the portions of the multiverse you could first-order impact are divided among them. Therefore, you aren’t significantly more or less likely to find yourself a second earlier or later.
Astronomy shows that there’s a mazillion stars up there. So we build a Dyson sphere and huge artificial womb clusters, and one generation later we launch one colony ship at each star. But in that generation, the fate of the universe becomes a lot more certain, so we should expect to find ourselves before that point, not after.
Physics shows that several constants are finely tuned to support organized matter. We can infer that elsewhere, they aren’t. Since you’d think that there are other, less precarious arrangements of physical law with complex consequences, we can also moderately update towards that very precariousness granting us unusual leverage about something valuable in the acausal marketplace.
History shows that we got lucky during the Cold War. We can slightly update towards:
Current events are important.
Current events are more likely after a Cold War.
Nuclear winter would settle the universe’s fate.
The news show that ours is the era of inadequate AI alignment theory. We can moderately update towards being in a position to affect that.
