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.
