I should mention conjecture #1,783: "on average, you always get a
higher expected utility with rational beliefs than irrational

Anyway, unless the situation is rather extreme (eg, the bomb is filled
with high explosive and shrapnel and it'll kill people), it should
take a huge number of these incidents to offset the 'benefits' of
utility function replacement. The monetary value of all the work Alf
and Beth do over an average lifetime could easily total several
million dollars.
