Eugenics is a matter of fact depending on what trait you're trying to bring out. If it isn't genetic, you're wasting your time. Also, when it comes to time, humans are the wrong species to supervise the selective breeding of humans, if only because it has to be multi-generational from the perspective of the experimentalists as well as the experimental subjects, and it's very hard to ensure an experiment runs to completion if it has to go on for multiple human lifetimes. But mostly, it's the fact actual eugenicists have all been deeply ignorant of genetics and allowed pure, baseless prejudice to drive their whole programs. Unless we consider Dor Yeshorim to be eugenicist, of course. https://en.wikipedia.org/wiki/Dor_Yeshorim https://en.wikipedia.org/wiki/Dor_Yeshorim
