Well, it is not every day that I can cite something that occurred at a conference that both Robin Hanson and I attended. But, we were at a conference honoring the work of David Grether, a giant of the field of Bayesian decision theory and econometrics, which was held on the George Mason campus on Friday, 4/6.

Anyway, a theme of several papers was that people are slow to update their priors in reality in many situations, although details are important. It is not clear what the source of this "inertia" is.
