I absolutely think that Bayesian reasoning and expected utility consequentialism can provide invaluable guides to ordinary interpersonal conflict.

If Bayesian rational thought is not the best answer for questions such as "How long do you wait before giving up (on the flakey date)?", then training oneself to think in those terms is training oneself to use a sub-optimal strategy for the real world.

The entire point, to me to using rational thought is because I believe rational thought is an optimal strategy. If it's not, why would you do it?
