Same with a lot of really cool progressive folk in the 1900s. Suffragettes, feminists, etc. It was really in vogue until the Nazis.
It was popular during a period when folks used science to make policy. It was also popular as a thought experiment on how to improve humanity and society as a whole but when faced with the reality that eugenics required the survivors to ignore the screams of the oppressed, ethics won out.
I mean, it doesn’t work but like, I get it. Moreso, after reading the news or watching any TV or talking to certain neighbors, I get the desire to, idk, maybe want some selective breeding. Just make people a teeny tiny bit less… stupid? Gullable? Irrational? If only there was a way. It wouldn’t work, but I get it.
Obviously it doesn’t quite work that way, is probably immortal and would take an extraordinary long time to even change something as ingrained as all that. Lol
If you want people to be less stupid or gullable, the answer is founding education programs to teach them scepticism.
About the irrationality, I think it’s part of what makes us human, biases can be overcome with some knowledge and humility but some things about humans like doing something for no reason or just because it fells good will never dissapear.
IQ is largely genetic.
Humans aren’t all identical and just different due to environment. Genetics will absolutely contribute to every attribute, positive or negative, and altering the average genetics of a population will absoultely change society.
