You could defintiely argue abductions and crime have reduced because there are fewer opportunities (because we keep the kids safe). But that still doesn't mean you can conclude the world is MORE dangerous.

Well, you could conclude the world is now more dangerous for any kid let wander - even if fewer do, and even if the observed average risk to any kid is lower (given they are allowed wander a lot less).

I don't want to be on the 'overprotect kids' side of the argument, but I'm not sure the numbers argur cleanly in one direction or the other.

I also often think of selection bias whenever anyone says "I was allowed do a lot more and we were fine" in the context of child safeguarding; because it also sounds like a lot of kids were abused in the past, who don't speak up in that conversation.

I don't know. I worry I overprotect my kids, but I also am not sure how to price in small risks of massively negative events. I think that's the crux of it for parents - trying to weigh hard tradeoffs.
