摘要

On the standard Bayesian picture, agents rationally change their beliefs by becoming certain of more and more facts. If we were to read this normatively, we would have to contend that it is irrational to forget. Michael Titelbaum wants to cure Bayesianism of this counterintuitive consequence by providing a new formal framework which he dubs the Certainty Loss Framework (CLF). The CLF is meant to offer the Bayesian answer to problems involving memory loss and, what is more, to problems exhibiting context-sensitivity. In this review, I shall briefly present the main ingredients of the CLF and illustrate it by Titelbaum's analysis of the Sleeping Beauty Problem, that familiar 'test bed' for formal frameworks that model memory loss and context-sensitivity. I shall conclude by mentioning some of the other topics the CLF can help clarify.
