Cass Report

A peer-reviewed critique has just been published

https://bmcmedresmethodol.biomedcentral.com/articles/10.1186/s12874-025-02581-7

On a quick skim, it seems to focus on methodology to construct an argument that as it is not perfect it should not be relied upon.

However there are some interesting statements:
I need an academic-to-layperson translation. It seems like the basis of the critique is that the Cass report is highly biased... but it looks like it's coming to that conclusion because the underlying studies that Cass reviewed were biased? It seems to imply that Cass directed the studies, rather than just evaluated existing studies done by other people. I'm not sure I'm reading it right though.

I think its more like "the Cass report didn't follow the gold standard for the type of review they were performing", while ignoring that there are reasons in the underlying studies that made it impossible to do that.

Its the repositioning from a mental health condition to one of bodily autonomy that is interesting, as I think this is an attempt to tie it into abortion rights arguments ie align you argument to a more popular position.

Children don't have full bodily autonomy, and I don't think they should - it would be insane to do so. Children aren't exactly known for good decision making, and someone somewhere will absolutely decide that they think skeletons are super cool, so they want to have their nose, their ears, and their lips removed so they look like a skull. Kids are frequently very dumb.

It's also a bad idea from a safeguarding perspective. "Bodily autonomy" has been a very common theme among a certain segment of child predators for a while now.

That's the thing isn't it. Even young adults are known for their bad decision making more than their good decisions. I do have a great deal of empathy for folks experiencing gender dysphoria but in what other context does anyone think children should be making permanent life altering decisions about anything.


It doesn't help that this puts me on the same side of the issues as genuine transphobes.
 

The real starting point of the critique is that, whatever methodology was used, the Cass Review and the York University team proceeded from a faulty perspective.

That is, they approached this by thinking about children and young people in distress, and investigated whether treatments provided to them did actually improve their mental health and wellbeing. This, according to the critique, is the wrong thing to do:

evaluating the efficacy of GAC based on psychosocial well-being alone is misguided
The authors believe this, because to them the purpose of allegedly “life-saving” interventions is not to improve mental wellbeing, but to fulfil cosmetic goals - and it is this fulfilment that will then consequentially improve mental health through realising one’s authentic self:

The primary goal of GAC is to prevent or induce the appearance of certain physical characteristics, and their physiological efficacy is undisputed. Mental health benefits are a logical consequence of living authentically
This is somewhat contradictory, in that mental health improvements are promoted as a “logical consequence” but attempting to evaluate whether this is actually true by checking to see if there are actually any mental health benefits is “misguided”.

But in any case the reasoning here is that what is important is how the child or young person is approached. Providing treatment to alleviate distress is wrong, pathologising and paternalistic and will harm mental wellbeing, while offering children unfettered access to cosmetic alterations to achieve their embodiment goals is right and guaranteed to improve wellbeing.

"Mental health benefits are a logical consequence of living authentically."

I would very much like whoever pronounced this nonsense to tell us how it works for paranoid schizophrenics, people with bipolar disorder, and people who suffer from factitious disorder by proxy.

I think that last item is particularly interesting. Does the victim realize mental health benefits from living their victimizer's authentic life?

Meh. Don't worry about it. All it means is that you're on the same side as people who recognize that the earth is not flat, even if some of those people happen to hold other views that you disagree with.

Thank you for the summary.

I can't adequately express how insane that premise seems to me.
 
Noted TERF Jesse Singal!
Joking, I think he's generally reliable and regularly listen to BARPod.
 
Came across a lovely phrase today, which will likely come in handy in discussions like this one:

Came across a lovely phrase today, which will likely come in handy in discussions like this one:
Just recently read Singal's critique of the preprint. They pointed out the discrepancy between the registered pre-research study design, including the hypotheses that were going to be tested, and the reported results that ended up completely dropping almost all of the intended hypotheses and introducing different ones that weren't part of the study design. Singal noted that there are situations where the registered design has to be altered during the research for legitimate reasons, but that it's usually expected that those reasons and the way in which the design was altered are provided as explanations for the deviation. Otherwise, it ends up being a case of throwing thousands of darts at the board, then removing 99% of them, then calling in all your friends to show off how accurate you are at darts...

IMO the preprint probably suffers from this problem twice—at the hypothesis selection level and then once again when the subjects with less desirable outcomes select themselves out of the process. With over one-third of participants lost to follow-up, this is a strong possibility.

Yep. Singal devoted a portion of their critique to the high likelihood of selection bias from that loss, and the lack of any metrics to support the assumption that those who persisted throughout the longitudinal study were representative of the population.

Aside: I can't remember if it's Singal or Wright, but one of them regularly posts articles highlighting the complete absurdity of 1) doctoral theses that got accepted and awarded passes and 2) "peer reviewed" articles of inarguably inane topics.

Doesn’t sound like something Singal would do. A lot of doctoral theses may indeed seem ridiculous and journal papers may seem “inarguably inane” according to a quick scan of the title, but that doesn’t always mean the research wasn’t well done and/or that the researcher hasn’t cut their teeth doing the research itself.

There are probably bigger problems when people do research that has more consequential outcomes but which turns out to be badly done.

There are, unfortunately, a lot of papers that make massive claims about how their drugs can treat Alzheimer’s or cancer which turn out to be fraudulent or overhyped. Or indeed, make astonishing claims about the value of puberty blockers or hormones that turn out to be badly done.
