A new study found that attractive female students earn higher grades than their unattractive female peers. The study was conducted by Rey Hernández-Julián and Christina Peters, who are economics professors at Metropolitan State University of Denver. They used volunteers (who were not students or professors) to rate the attractiveness of students from their college I.D. cards.

After rating attractiveness, they then examined 168,092 course grades awarded to those students. For female students, an increase of one standard deviation in attractiveness was associated with a 0.024 increase in grade (on a 4.0 scale). For male students, looks did not have a significant effect on grades. So basically it's a terrifying combination of gender inequality and double standards.
