> Why should facts exert only a slow, painstaking generational force on belief if people are actually rational? Surely it should have immediate effect?

Kind of like Bayesian inference. You have a prior and the different evidence moves the probability.

And it works a lot. For example, if you see a magician levitating, the evidence of your eyes seems to suggest that they are actually levititating. However, your priors tell you that the chance of that is still pretty low even with the new evidence. So this way, you don’t go run across a street magician and suddenly believe humans can levitate.
