 The evidential approach locates the authority that second-order information about our judgment has over us in the idea that it is evidence and we should respect our evidence. A state of self-doubt on this view is confidence both that q and that one’s evidence may well not support q. This state does not make the subject inconsistent, but is a state of level-splitting or akrasia. Matching on this view is constituted by agreement between one’s level of confidence in q and how far one thinks one’s evidence supports q, and doesn’t allow akrasia, but taking an evidential approach does not by itself settle whether rationality requires matching, or under what circumstances first- or second-order evidence should determine one’s first order confidence. General rules about how to adjudicate in self-doubting cases between the claims of the two orders of evidence may be hard to get due to paradoxes, and to the need in every instance to hold some features of rationality as undoubtable in order to initiate and resolve one’s doubt.
