 Although self-doubt under the current definition of it is not an incoherent state, Cal implies that rationality always requires a resolution of the doubt that brings matching between the two levels, and tells us that the matching consists in the alignment of subjective and perceived objective probabilities. High confidences in “q”, “I have confidence x in q”, and “the objective probability of q when I have confidence x in q is low” are not incoherent, but they do violate the Principal Principle. Re-Cal tells us how to get back in line with PP.
