I emphatically reject the author's opinion that "it’s not ridiculous to suggest, for example, that a randomized trial of puberty blockers would be a good idea." (Why not a randomised trial of ambulances? We'll send half of emergency callers an Uber instead.) But he's certainly thorough, and excepts like this are astounding.
The Cass review was an interesting juxtaposition. Some of the scientific arguments were very reasonable, and the York team generally did a decent job with the systematic reviews that informed the document. However, the review itself often positioned bizarre theories about gender dysphoria alongside data and evidence. I’ve recounted quite a few examples of this during my pieces, but I thought I’d share one more that I found recently:
“Research commentators recommend more investigation into consumption of online pornography and gender dysphoria is needed. Some researchers (Nadrowski, 2023) suggest that exploration with gender-questioning youth should include consideration of their engagement with pornographic content.” (Cass review, page 110)
This paragraph suggests that porn can potentially turn children trans. If you look up the reference, it is to this opinion piece from a psychiatrist. The paper itself contains no data connecting gender dysphoria to pornography, but basically argues that teen girls may view porn and become so disgusted with being women that they choose to instead become men. The paper also notes that “Girls affected by autism might be at higher risk because of their reduced mentalization capacities.”, although it does not provide any evidence that this is true.
The author of this opinion piece is a psychiatric trainee who lists their affiliation as Therapy First. Therapy First is an explicitly anti-medication group which campaigns to prevent children from being given hormones or puberty blockers for gender dysphoria - instead, they recommend psychotherapy as the first and in many cases only option. This is not evidence. It’s barely even an opinion. There is no reasonable excuse for the Cass review having included such a completely bizarre and unsubstantiated theory, especially without noting that it is entirely unsupported by even the most vague of evidence.
