Consider grade point average in college. Thanks to grade inflation, most students now get A’s and B’s, but a few range all the way down to F. With that kind of low ceiling, the high-achieving males cannot pull up the male average, but the loser males will pull it down. The result will be that women will get higher average grades than men — again despite no difference in average quality of work. The opposite result comes with salaries. There is a minimum wage but no maximum. Hence the high-achieving men can pull the male average up while the low-achieving ones can’t pull it down. The result? Men will get higher average salaries than women, even if there is no average difference on any relevant input. Today, sure enough, women get higher college grades but lower salaries than men. There is much discussion about what all this means and what should be done about it. But as you see, both facts could be just a statistical quirk stemming from male extremity.
