SHOCKER: Yes, Students Do Learn More From Attractive Teachers.

How to help students do better in school? Maybe we should try hiring better-looking teachers. Or subsidize gym memberships and makeovers for the teachers we already have.

Those, at least, are the implications of a new study from researchers at the University of Nevada, who designed a simple but revealing experiment using college students to see whether a lecturer’s attractiveness has any impact on how much of the lecture students retain. If you guessed that the answer is yes, go to the head of the class. Extra credit if you intuited that teacher attractiveness had other effects as well.

More surprising: The researchers don’t think that sexual interest explains the results, which held up whether the teacher and students were of the same sex or not. This suggests, they write, that the improved student performance was “driven by processes independent from human sexual attraction, such as attention and motivation.” Or, as one of them put it, it’s just human nature.

We’re superficial creatures.
