Bryan Caplan says intelligence research is very unpopular because it looks so bad to call half of people stupider than average, let alone stupid outright. Calling people stupid is rude.
But if this is the main thing going on, many other kinds of research should be similarly hated. It’s rude to call people lazy, ugly bastards whose mothers wouldn’t love them. Yet there is little hostility regarding research into conscientiousness, physical attractiveness, parental marriage status, or personal relationships. At least as far as I can tell. Is there? Or what else is going on with intelligence?
