I have heard some argue for adjusting priors as a way of dealing with deductive discoveries since we aren't logically omniscient. I think I like that solution. Realizing you forgot to carry a digit in a previous update isn't exactly new information about the belief. Obviously a perfect Bayesian wouldn't have this issue but I think we can feel free to evaluate priors given that we are so far away from that ideal.
