Like I said, this is not a maximization function. It is a filter.

The idea is to avoid things where the upside (even if highly likely) is small but the downside is (even if highly unlikely) catastrophic.

Kids need to go outside, occasionally get on a car or plane and they certainly need to be fed. These are all things were the upside is significant, so of course they need to be done and we do it without wondering about the downsides.

Going on the streets of Berlin by themselves at age 5 is an unnecessary, avoidable risk with very little benefit. It doesn't need to be done, so we don't. It's simple as that.
