Isn’t temporal inconsistency just selfishness? That is, before you know whether the coin came up heads or tails, you care about both possible futures. But after you find out that you’re in the tails’ universe you stop caring about the heads’ universe, because you’re selfish. UDT acts differently, because it is selfless, in that it keeps the same importance weights over all conceivable worlds.
It makes perfect sense to me that a rational agent would want to restrict the choices of its future self. I want to make sure that future-me doesn’t run off and do his own thing, screwing current-me over.
