I calculated mean harm avoidance scores as described in the last post by sex and sexual orientation. (N = 3,546, whites only)
Mean harm avoidance score
Compared to straight guys, gay and bisexual men have lower harm-avoidance scores (the difference is trivial, however). Lesbians and bisexual women also have lower means than their straight counterparts. The female straight-bisexual gap is about one-third of a standard deviation--a moderate difference. None of the female groups approach the low danger-averse scores of the male groups.
