Artificial intelligence can accurately guess whether people are gay or straight based on photos of their faces, according to new research suggesting that machines can have significantly better “gaydar” than humans.
The researchers say that homosexual men were found to have narrower jaws, longer noses, larger foreheads and less facial hair than heterosexual men, and that homosexual women tended to have larger jaws and smaller foreheads than heterosexual women.
They added: “Lesbians tended to use less eye makeup, had darker hair, and wore less revealing clothes (note the higher neckline)—indicating less feminine grooming and style. Furthermore, although women tend to smile more in general, lesbians smiled less than their heterosexual counterparts.
