are there any railguard in modern science against making something like eugenics rise again?
This is a follow-up question from my askhistorian thread here. As you can see in that thread that it seemed that eugenics was considered acceptable science back then.
This is I think a bit of more the philosophy and ethics question rather than pure science one but how do we know that some of the practice that we do today isn't causing active harm? Is it because modern science has become more concerned with ethics or is it because modern science has a lot more diverse background of scientist?
