Girls have higher grades but lower SAT scores. Grades measure consistency, whereas SAT scores measure innate talent.
Not exactly correct. The averages are about the same. IIRC there are differences in spread and there are more high end scores in the quantitative section for males. The test alleges that it only measures scholastic aptitude.
Re consistency, that’s a very valuable trait. I’d rather hire an engineer who is consistent with a 700 SAT-Q than an inconsistent one with straight 800’s.
