A reader wanted to know in the last post if I had a measure of verbal ability. The Add Health Study gave respondents a vocabulary test. Here are the means by sexual orientation:
Mean vocabulary score (sample size = 6,150, whites only)
Straight males 105.8*
Gay males 104.0
Straight females 104.2
*significantly higher than straight females
It's unexpected, but straight guys score significantly higher than straight girls. While the mean is low for gay guys and high for lesbians, they do not differ significantly from other groups.
