Although popular culture and many of the leading media organizations have bought wholeheartedly into the idea that gender identity is something distinct from one’s biological sex — that a man could be born in a woman’s body or vice versa — such beliefs have no grounding in any credible scientific evidence, according to a report published Monday in the journal The New Atlantis.
Arizona State University professor of statistics and biostatisticsLawrence S. Mayer and John Hopkins University Medical School professor of psychiatrics Paul McHugh co-authored the report, which examined top peer-reviewed studies in the biological, psychological, and social sciences.
“Examining research from the biological, psychological, and social sciences, this report shows that some of the most frequently heard claims about sexuality and gender are not supported by scientific evidence,” they noted.
Among the key findings listed by the authors was that, “The hypothesis that gender identity is an innate, fixed property of human beings that is independent of biological sex — that a person might be ‘a man trapped in a woman’s body’ or ‘a woman trapped in a man’s body’ — is not supported by scientific evidence.”
“Children are a special case when addressing transgender issues. Only a minority of children who experience cross-gender identification will continue to do so into adolescence or adulthood,” the authors continued.
“There is little scientific evidence for the therapeutic value of interventions that delay puberty or modify the secondary sex characteristics of adolescents, although some children may have improved psychological well-being if they are encouraged and supported in their cross-gender identification. There is no evidence that all children who express gender-atypical thoughts or behavior should be encouraged to become transgender.”
“An area of particular concern involves medical interventions for gender-nonconforming youth. They are increasingly receiving therapies that affirm their felt genders, and even hormone treatments or surgical modifications at young ages,” they added later.
“But the majority of children who identify as a gender that does not conform to their biological sex will no longer do so by the time they reach adulthood. We are disturbed and alarmed by the severity and irreversibility of some interventions being publicly discussed and employed for children.”
The report also found that, “The understanding of sexual orientation as an innate, biologically fixed property of human beings—the idea that people are ‘born that way’—is not supported by scientific evidence.”
“While there is evidence that biological factors such as genes and hormones are associated with sexual behaviors and attractions, there are no compelling causal biological explanations for human sexual orientation,” the authors explained.
“While minor differences in the brain structures and brain activity between homosexual and heterosexual individuals have been identified by researchers, such neurobiological findings do not demonstrate whether these differences are innate or are the result of environmental and psychological factors.”
McHugh previously served for 26 years as the Psychiatrist in Chief at John Hopkins Hospital.
“At Johns Hopkins, after pioneering sex-change surgery, we demonstrated that the practice brought no important benefits,” he wrote in a June 2015 essay on the topic.
In addition to his position at ASU, Mayer is currently a scholar in residence at Hopkins.
He dedicated his work on the report “to the LGBT community, which bears a disproportionate rate of mental health problems compared the population as a whole. We must find ways to relieve their suffering.”
