Here’s an example of it by the Left, or rather, the loss of one of its battles. Yes, women really are less predisposed to go into science. The Left opposes on principle the notion that many human traits are born, not made, because to admit that environment isn’t all is to concede defeat on their continual project to fight human nature. And it leads to absurdities like affirmative action demands that blacks, women, etc., must be represented in all endeavors in proportions equivalent to their proportions in the general population, and any deviation from this is prima facie evidence of racism and sexism. Larry Summers was famously bitten by this phenomenon a few years back.
