"A
Bayesian Approach to Probability Coordination"

Abstract:
It is usually accepted that there are two types of probability,
subjective and objective. Rational agents are supposed to
practice coordination: if an agent knows that the objectivity
probability of an event is x, then the agent's subjective probability
for that event should be x. This is a useful idea, but there are
problems justifying coordination noncircularly, and also specifying
when coordination should occur. This talk outlines a Bayesianstyle
approach to these issues.
