“Evidence Supporting the Biological Nature of Gender Identity” is a paper by Aruna Saraswat, MD, Megan Weinand, BA, BS, and Joshua D. Safer, MD. Recently, Dawn Ennis, ostensibly a reporter for The Advocate, used the paper to refute an assertion that there is no biological basis for gender identity, as follows:
What the paper actually says is that “(d)ifferent etiologies have been suggested as the cause of transgender identify however none have been proven definitively.” Additionally, the quote Ennis cites does not appear in the study, which you can read here. This is generally called “lying.” (The quote appears in a press release about the study, which you can read here.) Nothing in the paper shows a mechanism, or a connection of an observed structure with a specific behavioral manifestation. “We see this somewhat dissimilar physical structure” is a far cry from saying, “we know that this physical structure is connected directly to X behavior in this particular way.” Even fairly obvious, gross differences in brain mass between male and female persons has been proven to have merely a correlation to overall body size rather than to intelligence or anything so clear. Ennis continues the transgender tradition of cherry picking and, also, just making quotes up.
