The whole plot of the movie Idiocracy was based on the fact smart folks don’t have as many babies

Edit: To be fair, if you only include college educated folks as smart then you are not actually selecting for genetically smart people, just wealthy privileged people vaguely…on a worldwide scale… there is a subsistence farmer somewhere in sub Saharan Africa or northern Mongolia who milks yaks every day who is way “smarter” genetically than anyone here on lemmy I’m 99% sure of it. Me? I’m dumb as hell. But I was lucky enough to be able to go to college.
