Regarding the "education gap", there was one study (source unknown) that found on average students of liberal arts and other social sciences had higher GPAs, while students in math and other hard sciences had higher SAT scores. My point? GPAs are a terrible way to compare academic aptitude, because they are created from self-selected courses, and not evenly comparable. SAT scores on the other hand are standardized tests that attempt to make clean comparisons. Math and engineering are generally considered "harder" than English and art, so even if smarter people (as demonstrated by SAT scores) chose them, it's likely that they would under perform their social science peers in GPAs. Another more insidious assertion is that GPAs are typically softly selected and subject to human bias, especially in a field like English. Given that more women choose to go in to teaching, could they be giving preference to their female students? (I doubt it, but it is something to consider.) Note: I don't believe this study made any conclusions about gender, just education.
