+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."
+
+Scott Alexander has written about how [concept-shaped holes can be impossible to notice](https://slatestarcodex.com/2017/11/07/concept-shaped-holes-can-be-impossible-to-notice/). A culture whose [civic religion](https://slatestarcodex.com/2019/07/08/gay-rites-are-civil-rites/) celebrates being trans, and denies that gender has truth conditions other than the individual's say-so, has concept-shaped holes that make it hard to notice the hypothesis "I'm having a systematically worse childhood than I otherwise would have because all the grown-ups in my life have agreed I was a girl since I was three years old, even though all of my actual traits are sampled from the joint distribution of juvenile male humans, not juvenile female humans", even if it's true.
+
+... anyway, that's just a hypothesis that occured to me in early 2020, about something that _could_ happen in the culture of the current year, hypothetically, as far as I know. I'm not a parent and I haven't studied child development. (And even if the "Clever Hans" etiological pathway I conjectured is real, the extent to which it might apply to any particular case is complex; you could imagine a kid who was "actually trans", whose social transition merely happened earlier than it otherwise would have due to these dynamics.)
+
+For some reason, it seemed really important that I draft a Document about it with lots of citations to send to a few friends. If I get around to it, I might clean it up and publish it as a blog post (working title: "Trans Kids on the Margin; and, Harms from Misleading Training Data").
+
+Given that I spent so many hours on this little research/writing project in early 2020, I think it makes sense for me to mention at this point in the memoir, where it fits in chronologically. I have an inalienable right to talk about my own research interests, and talking about my research interests obviously doesn't violate any norm against leaking private information about someone else's family, or criticizing someone's parenting decisions.

+>
+> Dear Eliezer (cc Anna as mediator):
+>
+> Sorry, I'm getting _really really_ impatient (maybe you saw my impulsive Tweet-replies today; and I impulsively called Anna today; and I've spent the last few hours drafting an even more impulsive hysterical-and-shouty potential _Less Wrong_ post; but now I'm impulsively deciding to email you in the hopes that I can withhold the hysterical-and-shouty post in favor of a lower-drama option of your choice): **is there _any_ way we can resolve the categories dispute _in public_?! Not** any object-level gender stuff which you don't and shouldn't care about, **_just_ the philosophy-of-language part.**
+>
+> My grievance against you is *very* simple. [You are *on the public record* claiming that](https://twitter.com/ESYudkowsky/status/1067198993485058048):
+>
+>> you're not standing in defense of truth if you insist on a word, brought explicitly into question, being used with some particular meaning.
+>
+> I claim that this is _false_. **I think I _am_ standing in defense of truth when I insist on a word, brought explicitly into question, being used with some particular meaning, when I have an _argument_ for _why_ my preferred usage does a better job of "carving reality at the joints" and the one bringing my usage into question doesn't have such an argument. And in particular, "This word usage makes me sad" doesn't count as a relevant argument.** I [agree that words don't have intrinsic ontologically-basic meanings](https://www.lesswrong.com/posts/4hLcbXaqudM9wSeor/philosophy-in-the-darkest-timeline-basics-of-the-evolution), but precisely _because_ words don't have intrinsic ontologically-basic meanings, there's no _reason_ to challenge someone's word usage except _because_ of the hidden probabilistic inference it embodies.
+>
+> Imagine one day David Gerard of /r/SneerClub said, "Eliezer Yudkowsky is a white supremacist!" And you replied: "No, I'm not! That's a lie." And imagine E.T. Jaynes was still alive and piped up, "You are _ontologcially confused_ if you think that's a false assertion. You're not standing in defense of truth if you insist on words, such _white supremacist_, brought explicitly into question, being used with some particular meaning." Suppose you emailed Jaynes about it, and he brushed you off with, "But I didn't _say_ you were a white supremacist; I was only targeting a narrow ontology error." In this hypothetical situation, I think you might be pretty upset—perhaps upset enough to form a twenty-one month grudge against someone whom you used to idolize?
+>
+> I agree that pronouns don't have the same function as ordinary nouns. However, **in the English language as actually spoken by native speakers, I think that gender pronouns _do_ have effective "truth conditions" _as a matter of cognitive science_.** If someone said, "Come meet me and my friend at the mall; she's really cool and you'll like her", and then that friend turned out to look like me, **you would be surprised**.
+>
+> I don't see the _substantive_ difference between "You're not standing in defense of truth (...)" and "I can define a word any way I want." [...]
+>
+> [...]
+>
+> As far as your public output is concerned, it *looks like* you either changed your mind about how the philosophy of language works, or you think gender is somehow an exception. If you didn't change your mind, and you don't think gender is somehow an exception, is there some way we can _get that on the public record **somewhere**?!_
+>
+> As an example of such a "somewhere", I had asked you for a comment on my explanation, ["Where to Draw the Boundaries?"](https://www.lesswrong.com/posts/esRZaPXSHgWzyB2NL/where-to-draw-the-boundaries) (with non-politically-hazardous examples about dolphins and job titles) [... redacted ...] I asked for a comment from Anna, and at first she said that she would need to "red team" it first (because of the political context), and later she said that she was having difficulty for other reasons. Okay, the clarification doesn't have to be on _my_ post. **I don't care about credit! I don't care whether or not anyone is sorry! I just need this _trivial_ thing settled in public so that I can stop being in pain and move on with my life.**
+>
+> As I mentioned in my Tweets today, I have a longer and better explanation than "... Boundaries?" mostly drafted. (It's actually somewhat interesting; the logarithmic score doesn't work as a measure of category-system goodness because it can only reward you for the probability you assign to the _exact_ answer, but we _want_ "partial credit" for almost-right answers, so the expected squared error is actually better here, contrary to what you said in [the "Technical Explanation"](https://yudkowsky.net/rational/technical/) about what Bayesian statisticians do). [... redacted]
+>
+> The *only* thing I've been trying to do for the past twenty-one months
+is make this simple thing established "rationalist" knowledge:
+>
+> (1) For all nouns _N_, you can't define _N_ any way you want, [for at least 37 reasons](https://www.lesswrong.com/posts/FaJaCgqBKphrDzDSj/37-ways-that-words-can-be-wrong).
+>
+> (2) *Woman* is such a noun.
+>
+> (3) Therefore, you can't define the word *woman* any way you want.
+>
+> (Note, **this is _totally compatible_ with the claim that trans women are women, and trans men are men, and nonbinary people are nonbinary!** It's just that **you have to _argue_ for why those categorizations make sense in the context you're using the word**, rather than merely asserting it with an appeal to arbitrariness.)
+>
+> This is **literally _modus ponens_**. I don't understand how you expect people to trust you to save the world with a research community that _literally cannot perform modus ponens._
+>
+> [redacted ...] See, I thought you were playing on the chessboard of _being correct about rationality_. Such that, if you accidentally mislead people about your own philosophy of language, you could just ... issue a clarification? I and Michael and Ben and Sarah and [redacted] _and Jessica_ wrote to you about this and explained the problem in _painstaking_ detail, **and you stonewalled us.** Why? **Why is this so hard?!**
+>
+> [redacted]
+>
+> No. The thing that's been driving me nuts for twenty-one months is that <strong><em><span style="color: #F00000;">I expected Eliezer Yudkowsky to tell the truth</span></strong></em>. I remain,
