Are straight guys better at math than gay guys? Are lesbians better than hetero females? The Add Health Study asked teens what grade they earned in math last term. A's were assigned a 4, B's a 3, C's a 2, and D's or lower a 1. Here are the means:
Mean math score (sample size = 5,863)
Straight males 2.60
Gay males 2.30*
Straight females 2.75
*significantly lower than straight guys
While lesbians basically earn the same average math grade as heterosexuals, gay guys don't perform as well.
