It looks like
human nature is about what you'd always assumed:
Co-authored by two of the nation’s leading scholars on mental health and sexuality, the 143-page report discusses over 200 peer-reviewed studies in the biological, psychological, and social sciences, painstakingly documenting what scientific research shows and does not show about sexuality and gender.
The major takeaway, as the editor of the journal explains, is that “some of the most frequently heard claims about sexuality and gender are not supported by scientific evidence.”
Here are four of the report’s most important conclusions:
The belief that sexual orientation is an innate, biologically fixed human property—that people are ‘born that way’—is not supported by scientific evidence.
Likewise, the belief that gender identity is an innate, fixed human property independent of biological sex—so 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.
Only a minority of children who express gender-atypical thoughts or behavior will continue to do so into adolescence or adulthood. There is no evidence that all such children should be encouraged to become transgender, much less subjected to hormone treatments or surgery.
Non-heterosexual and transgender people have higher rates of mental health problems (anxiety, depression, suicide), as well as behavioral and social problems (substance abuse, intimate partner violence), than the general population. Discrimination alone does not account for the entire disparity.
The report, “Sexuality and Gender: Findings from the Biological, Psychological, and Social Sciences,” is co-authored by Dr. Lawrence Mayer and Dr. Paul McHugh. Mayer is a scholar-in-residence in the Department of Psychiatry at Johns Hopkins University and a professor of statistics and biostatistics at Arizona State University.
McHugh, whom the editor of The New Atlantis describes as “arguably the most important American psychiatrist of the last half-century,” is a professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine and was for 25 years the psychiatrist-in-chief at the Johns Hopkins Hospital. It was during his tenure as psychiatrist-in-chief at Johns Hopkins that he put an end to sex reassignment surgerythere, after a study launched at Hopkins revealed that it didn’t have the benefits for which doctors and patients had long hoped.
Implications for PolicyThe report focuses exclusively on what scientific research shows and does not show. But this science can have implications for public policy.
The report reviews rigorous research showing that ‘only a minority of children who experience cross-gender identification will continue to do so into adolescence or adulthood.’
Take, for example, our nation’s recent debates over transgender policies in schools. One of the consistent themes of the report is that science does not support the claim that “gender identity” is a fixed property independent of biological sex, but rather that a combination of biological, environmental, and experiential factors likely shape how individuals experience and express themselves when it comes to sex and gender.
The report also discusses the reality of neuroplasticity: that all of our brains can and do change throughout our lives (especially, but not only, in childhood) in response to our behavior and experiences. These changes in the brain can, in turn, influence future behavior.
This provides more reason for concern over the Obama administration’s recent transgender school policies. Beyond the privacy and safety concerns, there is thus also the potential that such policies will result in prolonged identification as transgender for students who otherwise would have naturally grown out of it.
The report reviews rigorous research showing that “only a minority of children who experience cross-gender identification will continue to do so into adolescence or adulthood.” Policymakers should be concerned with how misguided school policies might encourage students to identify as girls when they are boys, and vice versa, and might result in prolonged difficulties. As the report notes, “There is no evidence that all children who express gender-atypical thoughts or behavior should be encouraged to become transgender.”
Beyond school policies, the report raises concerns about proposed medical intervention in children. Mayer and McHugh write: “We are disturbed and alarmed by the severity and irreversibility of some interventions being publicly discussed and employed for children.”
They continue: “We are concerned by the increasing tendency toward encouraging children with gender identity issues to transition to their preferred gender through medical and then surgical procedures.” But as they note, “There is little scientific evidence for the therapeutic value of interventions that delay puberty or modify the secondary sex characteristics of adolescents.”
So, for starters, can we immediately cease all coddling of these weird impulses in our military, our intelligence agencies, and our State Department?
