Dear Eliezer, Could you pick a simpler example of a "traditional" style theory that has been replaced by "Bayesian" interpretation which is more efficient while having equal or better fit with reality. It seems that conjoining two difficult objects in the same example lessens the chance of anyone really getting the point, i..e quantum mechanics and proper epistemology considerations are not simple subjects. I must confess that I get the idea of the post but I cant really get a grip on the reasoning. Thanks, Dispose.
