 What if you’re uncertain about what’s rational? Arguably, this is Aisha’s situation: she’s unsure whether her evidence rationally supports G, as she initially thought it did, or whether hypoxia has confused her and her evidence doesn’t support G after all. One initially plausible response to this sort of situation is to say that when we’re uncertain, our beliefs should reflect a kind of weighted average of the responses we take to be possibly rational. This yields the result that if we’re about equally confident that we should believe P and that we should believe ~P, the thing to do is to suspend judgment.
