As a card-carrying non-parent, one of my favorite questions to ask parents (for some reason) is at what age they will feel comfortable leaving their kids alone for very short periods of time. The answers often surprise me and are a lot more conservative than when I grew up in the 1980s. This article goes deep on why that is. The bit about the "availability heuristic" is what I had previously suspected, but the additional finding about people conflating their own moral judgement with perceived actual risks is fascinating. I wonder what other issues in society this conflation occurs with.
