I keep hearing from anti-trans activists that this major review of the literature on the efficacy of transgender treatments, the Cass Report, confirms their position, which I don’t understand. What I’ve read of the report isn’t very overwhelming at all. Rather than wading into almost 400 pages of text, though, I thought this succinct summary of the whole thing was very good.
A systematic review collects all the published research in an area and ranks the research based on how likely it is to be reliable. The weakest form of evidence are case reports, where a doctor formally writes up an anecdote about a patient. The strongest form of evidence are randomized controlled trials where patients are randomly assigned to some type of medication or intervention, or to no intervention, or to a placebo, and the groups are compared to see how an intervention compares to alternatives/no treatment/placebo. Systematic reviews of several interventions for trans youth were undertaken by the University of York including puberty blockers, cross sex hormones, social transition, and psychosocial support measures.
The results of each of the systematic reviews was to characterize the overall evidence as weak, which was the Report’s most significant finding and has been widely reported. When looking more granularly at the York papers, a pattern appears of some papers showing a psychological benefit of the intervention, a smaller number showing no change positive or negative, and no papers showing any psychological harm. For example, in the systematic review of the evidence on puberty blockers, several included studies suggested psychological benefits to treatment in a range of areas, while a smaller number of studies found no significant impact. This was summarized in both the papers and the Report as “weak evidence” but could also be accurately described as “weak evidence (in favor of treatment).”
That the evidence was weak is not an indictment of the report — by their nature, case reports are necessarily weak. The alternative is to do controlled experimentation on human children, which is going to be even more problematic! The weak evidence is what we have, and that evidence says that, for the sake of the children, we should be treating kids.
The report itself actively endorses the use of puberty blockers, as well as other treatments, in addition to further studies of their effects. However, it takes a very conservative position on when young people should be allowed to take them, and even discouraged social transitioning in young children.
A full programme of research should be established to look at the characteristics, interventions and outcomes of every young person presenting to the NHS gender services.
The puberty blocker trial previously announced by NHS England should be part of a programme of research which also evaluates outcomes of psychosocial interventions and masculinising/ feminising hormones.
So I don’t get it. Why are the trans haters treating this as a vindication of their position? What I’m seeing is a cautious, conservative review that is compelled by the evidence to give cautious, conservative recommendations in favor of some degree of treatment, and I don’t care how much Helen Lewis and The Atlantic strain to twist it into a condemnation of American policy.
As usual, expect the issue to continue to be unresolved as ideology is used to torment trans kids further.
