 She could further tell herself that if the reason she persisted in believing F despite the altimeter reading was that she did in fact have low blood oxygen, then it was really lucky she had that hypoxia! Otherwise in evaluating her total evidence correctly she would have come to a false belief that not-F. Reasoning so, the pilot would be using her confidence in F as a reason to believe the altimeter reading was a misleading defeater, which does not seem to be a good way of finding that out. Moreover, if she did this argument a number of times she could use the track record so formed to bootstrap her way to judging herself reliable after all (Christensen 2007a,b; White 2009; Horowitz 2014—for general discussion of what is wrong with bootstrapping, see Vogel 2000 and Cohen 2002). Akrasia also sanctions correspondingly odd betting behavior.
