How can identify a gay

Further evidence for this point comes from studies in which people were asked why they made specific sexual orientation inferences. Some people seem to have more accurate gaydar than others.

For instance, people who hold anti-gay views typically perform worse in gaydar studies; by contrast, sexual minorities and people who have more familiarity. Put another way, when women are at peak fertility, their ability to distinguish men who are gay from those who are straight appears to improve.

However, in reality, there are far more than just two sexualities out there. So what happens when bisexual people are included in gaydar research? Overall, gaydar helps people make sexual orientation inferences that are better than chance guessing; however, they are far from perfect. Some researchers believe that accuracy could potentially be even higher in the real world, where people usually have more cues and information to go off of compared to lab studies.

Kosinski seems unperturbed by the furore over Cambridge Analytica, which he feels has unfairly maligned psychometric micro-targeting in politics. Where Lombroso used calipers and craniographs, Kosinski has been using neural networks to find patterns in photos scraped from the internet.

There is growing evidence, he insists, that links between faces and psychology exist, even if they are invisible to the human eye; now, with advances in machine learning, such links can be perceived. In a paper published last year , Kosinski and a Stanford computer scientist, Yilun Wang, reported that a machine-learning system was able to distinguish between photos of gay and straight people with a high degree of accuracy.

Kosinski received a deluge of emails, many from people who told him they were confused about their sexuality and hoped he would run their photo through his algorithm. He declined. There was also anger that Kosinski had conducted research on a technology that could be used to persecute gay people in countries such as Iran and Saudi Arabia, where homosexuality is punishable by death. Kosinski says his critics missed the point.

But then a colleague asked me if I would be able to look myself in the mirror if, one day, a company or a government deployed a similar technique to hurt people.

One vocal critic of that defence is the Princeton professor Alexander Todorov , who has conducted some of the most widely cited research into faces and psychology. Self-posted photos on dating websites, Todorov points out, project a number of non-facial clues. Kosinski acknowledges that his machine learning system detects unrelated signals, but is adamant the software also distinguishes between facial structures.

His findings are consistent with the prenatal hormone theory of sexual orientation, he says, which argues that the levels of androgens foetuses are exposed to in the womb help determine whether people are straight or gay. The opposite should be true for lesbians. While he does not deny the influence of social and environmental factors on our personalities, he plays them down. Computers can malfunction.

Kosinski has a different take. There are thousands or millions of others that we are unaware of, that computers could very easily detect.

Would he ever undertake similar research? If you have doubts about his sexuality, then you have landed on the right page. Before we tell you what to do next, let us tell you that it is okay to sometimes wonder about such things. But if you are doubting only because he gets too emotional or he takes too much time to look after himself or he just loves looking good, then you are wrong because that does not make your boyfriend gay.
