 The approach to epistemic self-doubt in terms of higher-order probability allows the state of self-doubt to be rational (coherent), and to be rationally resolved. Cal expresses a requirement of matching between the two orders in all cases, though it does not imply that attributing a mismatch to oneself is incoherent. Neither order is always dominant; both orders always make a contribution to determining the resolution at the first order of conflicts between orders, and their relative contribution depends on the quality of the evidence at each order. Cal and Re-Cal explain why one should revise in light of higher-order evidence, when one should, by reference only to probabilistic coherence, the Principal Principle, and conditionalization. Cal and Re-Cal are general and make available all of the resources of the Bayesian framework for analysis of higher-order evidence. A further notable fact about the framework is that Re-Cal allows for cases where news about one’s reliability should increase one’s confidence, which would be appropriate for example in cases, easy to imagine, where one acquired evidence that one was systematically underconfident. Thus, it is possible for second-order evidence to make it rational to be not only steadfast or conciliatory, but even emboldened.
