Going against currently expected utilities

Today I am making an important decision between A and B. The expected utilities of A and B depend on a large collection of empirical propositions p₁, ..., p_n. Yesterday, I spent a long time investigating the truth values of these empirical propositions and I calculated the expected utility of A to be much higher than that of B. However, today I have forgotten the results of my investigations into p₁, ..., p_n, though I still remember that A had a higher expected utility given these investigations.

Having forgotten the results of my investigations into p₁, ..., p_n, my credences for them have gone back to some sort of default priors. Relative to these defaults, I know that B has higher expected utility than A.

Clearly, I should still choose A over B: I should go with the results of my careful investigations rather than the default priors. Yet it seems that I also know that relative to my current credences, the expected utility of B is higher than that of A.

This seems very strange: it seems I should go for the option with the smaller expected utility here.

Here is one possible move: deny that expected utilities are grounded in our credences. Thus, it could be that I still hold a higher expected utility for A even though a calculation based on my current credences would make B have the higher expected utility. I like this move, but it has a bit of a problem: I may well have forgotten what the expected utilities of A and B were, and only remember that A’s was higher than B’s.

Here is a second move: this is a case where I now have inconsistent credences. For if I keep my credences in p₁, ..., p_n at their default levels, I have a piece of evidence I have not updated my credences on, namely this: the expected utility of A is higher than that of B relative to the posterior credences obtained by gathering the now-forgotten evidence. What I should do is update my credences in p₁, ..., p_n on this piece of evidence, and calculate the expected utilities. If all goes well—but right now I don’t know if there is any mathematical guarantee that it will—then I will get a new set of credences relative to which A has a higher expected utility than B.
