A rare point of agreement between hard biodeterminists and hard socialists is that telling kids that they’re failing because they just don’t have the right work ethic is a crappy thing to do
. It’s usually false and it will make them feel terrible. Behavioral genetics studies show pretty clearly that at least 50% of success at academics and sports
is genetic; various sociologists have put a lot of work into proving that your position in a biased society covers a pretty big portion of the remainder. If somebody who was born with the dice stacked against them works very hard, then they might find themselves at A2 above. To deny this in favor of a “everything is about how hard you work” is to offend the sensibilities of sensible people on the left and right alike.
