I liked this rundown of the Cass Review because the press release and the attached briefing go into why the Cass Review is bad science. A few items from the briefing:
- Trans people were excluded from the core team, but conversion therapist advocates were included.
- The bar for a "quality" study was set impossibly high, requiring blinding and a control group. Blinding is not possible with puberty blockers or hormones because the effects of either are obvious. A control group has significant unethical issues.
- Some claims are made without evidence, like "For many centuries transgender people have been predominantly trans females, commonly presenting in adulthood." No such evidence exists.
