Scholars at Johns Hopkins University released a new report on Monday which argues that there is not sufficient evidence to suggest that lesbian, gay, or transgender people are born with this sexual orientation or gender identity. "The idea there that sexual orientation is fluid, that people change as people grow," Lawrence Mayer, a co-author of the report and a scholar-in-residence at Johns Hopkins University's psychiatry department, as well as a professor of statistics and biostatistics at Arizona State University, told The Christian Post . "There are probably some people that identify as hetrosexual [ sic] that then later on identified as homosexual, so it goes both ways. The importance there is the fluidity and flexibility that these things change in time." The three-part, 143-page report , which appeared in the Fall 2016 edition of The New Atlantis, also investigated other commonly accepted ideas about homosexuality and transgenderism.
Mayer and his co-author Paul McHugh, a professor of psychiatry and behavioral sciences at Johns Hopkins, challenged the claim that discrimination and social stigma are the only reasons why homosexual and transgender people suffer higher rates of mental health problems and are more likely to commit suicide. The study breaks down in three parts: First, Mayer and McHugh examined whether homosexuality is an inherited trait, and concluded that people are not simply "born that way." Second, they looked at the causes of the poor mental health associated with gay and transgender people, concluding that social stress does not explain all of it. Finally, they studied transgenderism, concluding that it is not innate and that transgender "treatments" are associated with negative outcomes. The report found insufficient evidence to back up the idea that people are born with innate sexual attractions.
Mayer and McHugh examined past studies which show a modest association between genetic factors and sexual orientation, but these studies have not been able to pinpoint particular genes responsible. Other hypothesized biological causes, such as prenatal development and hormones, have also been linked to sexual orientation, but that evidence is also limited. "Studies of the brains of homosexuals and heterosexuals have found some differences, but have not demonstrated that these differences are inborn rather than the result of environmental factors that influenced both psychological and neurobiological traits," the report explained. "One environmental factor that appears to be correlated with non-heterosexuality is child sexual abuse victimization, which may also contribute to the higher rates." The report cited the National Longitudinal Study of Adolescent to Adult Health, which tracked the sexual orientation of children aged 7 to 12 in 1994-1995 and again in 2007-2008. Eighty percent of male respondents who had reported same-sex attraction and both-sex attraction in childhood later identified as exclusively heterosexual, while more than half of the females who reported both-sex attraction as children reported exclusive attraction to men as adults. Mayer and McHugh also analyzed twins.
They pointed to a 2010 study by psychiatric epidemiologist Niklas Långström which analyzed 3,826 identical and fraternal same-sex twin pairs. Both twins had at least one same-sex partner in only 18 percent of male identical twins, and 11 percent of male fraternal twins. For women, both twins had at least one homosexual partner in 22 percent of identical twins and 17 percent of fraternal twins. "Summarizing the studies of twins, we can say that there is no reliable scientific evidence that sexual orientation is determined by a person's genes," the researchers wrote. "But there is evidence that genes play a role in influencing sexual orientation." "So the question 'Are gay people born that way?' requires clarification.
There is virtually no evidence that anyone, gay or straight, is 'born that way' if it means that their sexual orientation was genetically determined," the report explained (emphasis added). "But there is some evidence from the twin studies that certain genetic profiles probably increase the likelihood the person later identifies as gay or engages in same-sex sexual behavior."
