Are we in agreement that intelligence is inherited as a mixture of nature and nurture? What I say next does depend on agreement here.

What do you mean by intelligence? General intelligence has never been scientifically proven to exist. So in that sense: I don’t believe in intelligence, either.

Let’s say Priddy sterilized someone, they met a partner who also loved playing violin, and they adopted a kid. The sterilization would do nothing to prevent the kid from knowing a thing or two about the violin. Do we agree? Do you see what I mean about sterilization not preventing the inheritance of non-biological traits?

Apart from the morbidity of you using that historical example as a juming off point for a thought experiment: That’s assuming that the law would have allowed for the sterilized person to adopt someone. It certainly wouldn’t have.
