alt Hacker NewsI think the problem here is what are you supposed to do with very low probability really bad events. I.e. your kid being kidnapped or similar. The probability of this extremely low, but it is unimaginatively bad. Therefore any small thing you do that will reduce the chance of this happening may seem reasonable. It is not clear to me how to think about this rationally.
Part of the way to think about it is that you simply can't control such events. We never could and we never will. Trying to do so is a losing game for temporary psychological comfort only. I think the key is that the "small things" that you do are unlikely to actually reduce the probability in practice.
