  But suppose that whenever the person withholds, it turns out they should go left. In this case, withholding does not escape the problem. Like modesty, there are special issues with self-ascription; one can accept that others are anti-experts with no problems, but self-ascription seems self-undermining. In this sense, it can be seen as a limit on epistemic modesty—rationality prohibits one from thinking that their own faculties are anti-reliable. So, in the more difficult directions example, Sorensen (1987, 308ff.) claims one cannot rationally believe that one is in such a situation. Gilbert (1971) makes a similar claim in the moral domain, arguing that there are rational limits on the self-ascription of moral vices.
