If you just use utility function that favors big number of observers getting personal utility, then you’ll automatically act as if you are in the many-observers world when you are uncertain. This doesn’t require revising the level of belief in the logical fact, and allows to switch to the minority option upon discovering the corresponding solution. The same setting allows to estimate the value of new logical information about the fact. (This has to refer to some standard position on anthropics.)
