We have an expression, "You can lead a horse to water, but you can't make it drink." I reckon there is a good chance that Dr. Peterson's re-education is not going to take. But, he will have complied to keep his license so the Court can be satisfied that it did something, regardless of the intervention's effectiveness.
In this particular case, the court's not really making him do anything. It sounds like the court just declined to get involved in an industry-specific licensing agreement.
However, one interesting facet of this case.
Per CBC's follow up article:
Egale Canada, which had intervenor status in the case, celebrated Thursday's Supreme Court decision. It said 2SLGBTQ+ communities can face discrimination in accessing health care.
"This is why a clinical psychologist making transphobic claims is particularly harmful and directly interferes with trans people's autonomy," said the national advocacy group's legal director, Bennett Jensen, in a media statement.
"Psychologists belong to the group of professions that act as gatekeepers to gender-affirming health care, and they must be held accountable"
If psychology/psychologists are as important as other health providers, and it's supposed to be about science and evidence, and clinicians and "experts" making decisions based on their findings and observations, and the point of contention is professional disagreements over to how to discuss Trans issues within the field and publicly, why was a biased LGBTQ+ activism organization given intervenor status in a case about it and getting to weigh in on which
providers should be "held accountable"? That seems like it'd be undermining the credibility of the case as well as the profession as a whole, if people want to treat the profession as actually being in the realm of healthcare.
Would we handle any other healthcare matter in such a way?
If there was a particular case where there was a dispute between a doctor and the medical review board about whether or not the doctor was handing out prescriptions for medicinal marijuana too freely, and the licensing spat made it all the way to a court, would we want lawyers representing anti-Marijuana activist groups to be injected into the legal process as intervenors? Or would we say that it's one of the topics that should exist outside the realm of special interest influence?
To me, Egale's statement reads as:
"We want to prop this specific science-adjacent subjective profession up as the gate-keepers to the thing we want (because the perception of gate-keepers existing gives the patina of rigorousness and legitimacy), but we need to make sure they all agree with what we want so that there aren't
actually any barriers, but we can still use them to claim
the science & medical community is on our side"
To put it more directly, they want a field that's viewed with the same legitimacy as other healthcare fields, but they want that field to be unified behind catering to them and not pushing back at all.... In other words, it sounds like Egale's expectation of the field is for it to mental health equivalent of a "pill mill".
