According to its authors, who say they were "really disturbed" by their findings, the accuracy of an AI system can reach 91 per cent for homosexual men and 83 per cent for homosexual women. Human judges, meanwhile, achieved an accuracy of 61 per cent for men and 54 per cent for women, the research claims. 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.

Although I've always wanted this particular superhuman power, I've never been very good at detecting other men's sexual orientation. Findings from a recent study published in the Journal of Experimental Social Psychology , however, suggest I may be underestimating my gaydar abilities. The January study investigated people's ability to identify homosexual men from pictures of their faces alone. In an initial experiment, researchers Nicholas Rule and Nalini Ambady from Tufts University perused online dating sites and carefully selected 45 straight male faces and 45 gay male faces. All of these photos were matched for orientation only faces shown looking forward were used and facial alterations none of the images contained jewelry, glasses or facial hair. To control for context, the faces were also cut and pasted onto a white background for the study. These 90 faces were then shown to 90 participants in random order, who were asked simply to judge the target's "probable sexual orientation" gay or straight by pressing a button.
