Isn’t that exactly the question we often ask juries to consider in, for example, liability lawsuits? “It was rational for the defendant to assume (or conclude under the circumstances) X, but in fact not-X, because of Y or because they got really unlucky, and therefore we find them not liable.”
I will happily concede that juries do a poor job accounting for hindsight bias, and hold defendants to low standards of rationality, but it seems to me that the usual question is something like “even though not-X, was it rational to believe X?”
Whether “reasonable” and “rational” really mean the same thing in this case is open, but I submit that it is the same question as whether juries hold defendants to reasonable standards of rationality.
