The data also identified certain trends, including that gay men had narrower jaws, longer noses and larger foreheads than straight men, and that gay women had larger jaws and smaller foreheads compared to straight women. Human judges performed much worse than the algorithm, accurately identifying orientation only 61 per cent of the time for men and 54 per cent for women. While the findings have clear limits when it comes to gender and sexuality — people of colour were not included in the study, and there was no consideration of transgender or bisexual people — the implications for artificial intelligence AI are vast and alarming. That means building this kind of software and publicising it is itself controversial given concerns that it could encourage harmful applications. But the authors argued that the technology already exists, and its capabilities are important to expose so that governments and companies can proactively consider privacy risks and the need for safeguards and regulations.
But Spitzer's study, which has not yet been published or reviewed, seems to indicate otherwise. Self-identification was assessed on a 5-point scale and all three non-exclusive options were combined for bisexual self-identification. Gender identities Sexual identities Sexual diversities. Social attitudes Prejudice Violence.

Nsikan Akpan Nsikan Akpan. In its stead, the report finds that human DNA cannot predict who is gay or heterosexual. Sexuality cannot be pinned down by biology, psychology or life experiences, this study and others show, because human sexual attraction is decided by all these factors. The study shows that genes play a small and limited role in determining sexuality.
That pattern is similar to other heritable but complex characteristics like height or a proclivity toward trying new things. Of course, ethical concerns arise with any attempt to use biology to explain complex human behavior like sexuality. People like Michael Bailey, a psychologist at Northwestern University who conducted much of the early research into the heritability of sexuality, warned against taking this new genetics study — or any research on sexual behavior — out of context.
We knew that before this study. The study set out to investigate a year-old genetics debate in sexuality by combing through two huge collections of DNA profiles: the UK Biobank and 23andMe. It contains the DNA sequences of , middle-aged people, who were 40 to 69 years old when they were recruited between and This study pulled the information for , people across the UK Biobank and 23andMe who had taken a survey about various life behaviors, including whether they had engaged in a sexual experience with a person of the same sex at any point in their life.
Think of all of humanity as consisting of 7 billion copies of the same book. All humans contain the same words — or individual genes — that make up how we think and how our organs function. But the words in our respective genetic books — or their code — look slightly different. Some of my letters might be red, while some of yours are colored blue. This may sound counterintuitive, but those variations can also share similarities. The books that make up my family look similar to each other — in this example, they contain other shades of red.
The technique can be used to suss out why certain people and their particular genetic variations correlate with health conditions like autism , physical traits like curly hair or colorblindness, behaviors like handedness or emotions like loneliness. The strongest signals came from five random genes.
Two of those genes correlated with same-sex sexuality in males, one of which is known to influence the sense of smell. One gene cropped up for females and two others showed solid patterns in both males and females. But their individual scores never passed this 1-percent mark — meaning they are all minor contributors to same-sex sexual behavior. Humans have tried to understand human sexuality for centuries — and genetics researchers joined the fray in the early s after a series of studies on twins suggested homosexuality ran in families.
These kinds of studies have continued through the years, going as far as pinpointing a gene on the X chromosome — Xq28 — as the culprit. His comments speak to the larger narrative about using biology to define complex behaviors — like sexuality — when science is always evolving and takes time to find anything close to definitive. Those early studies stumbled upon a concrete pattern: Sexuality can run in families and thus must have a genetic component.
But back then, the scientists had no way of comprehensively exploring this issue. Genome sequencing took decades to slowly mature into what it is today, and twins alone cannot represent the genetic complexity of our species. Those projects — known as linkage studies — were designed to find single major genes that appeared to have a big effect on sexuality, said Dr.
And even this new study has a big limitation, one that has been inherent to major genomic studies for the last two decades: GWAS studies are too white. They did attempt to examine some elements of this continuum by conducting GWAS analysis on three smaller DNA databases wherein the participants had been surveyed using the Kinsey Scale.
In other words, it tries to judge if a person leans gay, straight or bisexual. He did agree with Neale that the debate is now closed on whether any single gene is responsible for sexual orientation.

The fact no one likes to admit: many gay men could just have easily been straight | The Spectator
A controversial new study says yes — if they really want to. Critics, though, say the study's subjects may be deluding themselves and that the subject group was scientifically invalid because many of them were referred by anti-gay religious groups. Robert Spitzer, a psychiatry professor at Columbia University, said he began his study as a skeptic — believing, as major mental health organizations do, that sexual orientation cannot be changed, and attempts to do so can even cause harm.
But Spitzer's study, which has not yet been published or reviewed, seems to indicate otherwise. Spitzer says he spoke to men and 57 women who say they changed their orientation from gay to straight, and concluded that 66 percent of the men and 44 percent of women reached what he called good heterosexual functioning — a sustained, loving heterosexual relationship within the past year and getting enough emotional satisfaction to rate at least a seven on a point scale.
He said those who changed their orientation had satisfying heterosexual sex at least monthly and never or rarely thought of someone of the same sex during intercourse. He also found that 89 percent of men and 95 percent of women were bothered not at all or only slightly by unwanted homosexual feelings. However, only 11 percent of men and 37 percent of women reported a complete absence of homosexual indicators. But they managed to change those feelings, he added. The study reopens the debate over "reparative therapy," or treatment to change sexual preference.
Spitzer argues that highly motivated gays can in fact change that preference — with a lot of effort. But critics have challenged the study, even before it was formally unveiled at today's session of the American Psychiatric Association's annual meeting in New Orleans, which was jammed with television cameras reporting on the presentation. Another study presented today even contradicted the finding.
Ariel Shidlo and Michael Shroeder, two psychologists in private practice in New York City, found that of homosexual subjects who received therapy to change their sexual orientation, the majority failed to do so. Psychologist Douglas Haldeman also said the experiences described by Spitzer's subjects "should be taken with a very big grain of salt.
What I am disputing is that is invariably the outcome. In fact, he said, many of his subjects had been despondent and even suicidal themselves, for the opposite reason — "precisely because they had previously thought there was no hope for them, and they had been told by many mental health professionals that there was no hope for them, they had to just learn to live with their homosexual feelings. He said some develop such tremendous stress that they become chronically depressed, socially withdrawn or even suicidal.
But Spitzer says his study shows that some homosexuals making some effort, usually for a few years, make the change. Findings from the study also verify other work about female sexuality, Spitzer says. Haldeman, however, noted that some 43 percent of those sampled were referred by religious groups that condemn homosexuality.
And, he said, it doesn't mean they aren't telling the truth. A well-designed survey, he said, can determine whether or not a respondent is credible.
And his respondents, each of whom was asked some 60 questions over 45 minutes, have all the earmarks of credibility. In fact, he said, to dismiss his survey would be to dismiss an awful lot of psychological and psychiatric research. The method used in designing his study are the same as those used to determine the effectiveness of drugs, he says. He said he asked very detailed questions not only about sexual attraction, but about fantasies during masturbation and sex, and yearnings for romantic and emotional involvement with the same sex and a variety of other variables that indicate sexual orientation.
Ironically, Spitzer had until now been something of a hero in the gay community.
