Courageous for that publication. Pop psychology has long catered to people who like shallow thinking, and who easily fall prey to popular fads. Surprising that they would actually publish this. The feminazis will be reading it after they come back from the Equinox worship in Stonehenge, and will be condemning it.
The article does say that the differences are inherent, and are genetic. This destroys the fake/phoney/fraud construct of the militant left. I predict that the author is trashed.
What I would like to see in print, is an article warning people and their doctors that knowledge of the person’s sex IS important for diagnosis and treatment, and that LYING, and claiming to be a sex other than one’s real one, can lead to improper diagnosis and/or treatment. So, a male who has some things lopped off and who claims to be a female had damned well better tell his doctor about his fantasy! The doctor IS NOT responsible for the outcome when the patient lies about his sex.
From my quite sporadic and unsystematic forays into the literature, I get the impression that a great many people in fields related to cognitive psychology and psychometrics are just waiting for the moment when it becomes possible to speak and write honestly about gender and racial differences without ending one's career. This is certainly one of the fields in which a dogmatic lie is enforced in the public square -- while virtually everyone with serious chops in the field knows its a lie.
