> how would you implement this without going into nazi-like levels of control on the individual?

I wasn't really talking about the practicality of it, especially because it's the furthest thing from the Overton Window imaginable. Literally everything else is closer to it. Even marrying toddlers, as shown by recent events. Slavery's half-inside the window.

It was just about the fact that it's possible.

> assuming "we have the science".

This isn't really disputable, given how much bigger nature is than nurture. See e.g. POTUS and his dad. Obviously it's not 100%, nothing is, but denying that "we have the science" to massively influence things would be purely out of ideological dislike.

Humans have practiced eugenics on animals on an absurdly huge scale. See domestication and its effects. Humans are animals, the idea that it would somehow be completely different for them has no basis in science.

Lmao you can’t. Eugenics is evil and denies reproductive rights, bodily autonomy at the most basic animal level. It is literally the idea of creating a master race and culling off anyone who doesn’t conform.

If you find yourself in a situation where you want to do something Nazis did — just not that way — you are halfway there.
