+What made this crazy, in my view, was not just that child transition is a dubious treatment decision, but that it's a dubious treatment decision made on the basis of the obvious falsehood that "trans" was one thing: the cultural phenomenon of "trans kids" was being used to legitimize trans _adults_, even though the vast supermajority of trans adults were in the AGP taxon and therefore _had never resembled_ these HSTS-taxon kids. That is: pre-gay kids are being sterilized in order to affirm the narcissistic delusions of _guys like me_.
+
+That much was obvious to anyone who's had their Blanchardian enlightenment, and wouldn't have been worth the effort of writing a special private Document about. The disturbing hypothesis that occured to me in early 2020 was that, in the culture of the current year, affirmation of a cross-sex identity might happen to kids _who weren't even HSTS-taxon at all_.
+
+Very small children who are just learning what words mean say a lot of things that aren't true (I'm a grown-up; I'm a cat; I'm a dragon), and grownups tend to play along _in the moment_ as a fantasy game, but they don't _coordinate to make that the permanent new social reality_. Ten years ago, if an otherwise ordinary three-year-old boy had occasionally claimed to be a girl, I think his nice smart liberal unschooling grownups would treat it about the same way as when the kid claims to be a cat. (I'm going with the MtF case with only a little loss of generality; I don't think the egregore is quite as eager to "trans" females at this age.)
+
+But if the grown-ups have been trained to believe that "trans kids know who they are"—if they're emotionally eager at the prospect of having a transgender child, or fearful of the damage they might do by not affirming—they might selectively attend to confirming evidence that the child "is trans", selectively ignore evidence that the kid "is cis", and end up reinforcing a cross-sex identity that _would not have existed_ if not for their belief in it.
+
+Crucially, if innate gender identity _isn't_ a feature of toddler psychology, _the child has no way to know anything is "wrong."_ If none of the grown-ups can say, "You're a boy because boys are the ones with penises" (because that's not what people are supposed to believe in the current year), how is the child supposed to figure that out independently? [_Toddlers_ are not very sexually dimorphic](/2019/Jan/the-dialectic/), but sex differences in play styles tend to emerge within a few years. (Did you know the [sex difference in preference for toy cars is _d_ ≈ 2.44?!](/papers/davis-hines-how_large_are_gender_differences_in_toy_preferences.pdf)) What happens when the kid develops a self-identity as "a girl", only to find out, potentially years later, that she noticeably doesn't fit in with the (cis) girls on the [many occasions that no one has explicitly spelled out in advance](/2019/Dec/more-schelling/) where people are using "gender" (percieved sex) to make a prediction or decision?
+
+Some might protest, "But what's the harm? She can always change her mind later if she decides she's actually a boy." I don't doubt that if the child were to clearly and distinctly insist, "I'm definitely a boy," the nice smart liberal grown-ups would unhesitatingly accept that.
+
+But the harm I'm theorizing is _not_ that the child has an intrinsic male identity that hurts to not be respected. (What _is_ an "identity", apart from the ordinary factual belief that one is of a particular sex?) Rather, the concern is that social transition prompts everyone, _including the child themself_, to use their mental models of girls (juvenile female humans) to make (mostly subconscious rather than deliberative) predictions and decisions about the child, which will be a systematically worse statistical fit than their models of boys (juvenile male humans), because the child is, in fact, a boy (juvenile male human), and those miscalibrated predictions and decisions will make the child's life worse in a complicated, illegible way that doesn't necessarily result in the child spontaneously verbally asserting, "I prefer that you call me a boy."
