 Sorensen pointed out that if S is consistent and knows perfectly what her beliefs are, then she cannot believe she is an anti-expert. For if S believes p then, by perfect self-knowledge, she believes that she believes p, but her beliefs that p and that she believes p are together inconsistent with both of the disjuncts of A. Similarly for the case where S does not believe p. This phenomenon generalizes from outright belief to degrees of belief, and from perfect knowledge of one’s beliefs to decent but imperfect knowledge of them (Egan &amp; Elga 2005: 84ff.).
