Some studies have indicated that there may be intelligence differences between different sexual
orientations or gender identifications. We investigated whether intelligence was predicted by sexual
orientation and gender identity in a large sample of dating site users from OKCupid (N = ~36,866). In
our regression model, we found that homosexuals were slightly below heterosexuals in intelligence, β
= -0.07 (corrected -0.09), while bisexuals were slightly higher, β = 0.17 (cor. 0.22), and people with
less common orientations were much higher, β = 0.73 (cor. 0.93). There was no interaction between
orientation and gender. Furthermore, women obtained lower scores than men, β = -0.14 (cor. -0.18, -
2.67 IQ), and individuals who adopted non-binary gender identity had about average intelligence, β =
0.03 (cor. 0.03). It was found that non-binary gender identity predicts substantially higher
intelligence when analysed alone, but this was mediated by its statistical association with rare sexual
orientations. Results were discussed in the light of a development of Kanazawa’s Savanna-IQ
Interaction hypothesis and the Cultural Mediation hypothesis. -
