+At least, a _pedagogy_ mistake. If Yudkowsky _just_ wanted to make a politically neutral technical point about the difference between fact-claims and policy claims _without_ "picking a side" in the broader cultural war dispute, these Tweets did a very poor job of it. I of course agree that pronoun usage conventions, and conventions about who uses what bathroom, are not, themselves, factual assertions about sex chromosomes in particular. I'm not saying that Yudkowsky made a false statement there. Rather, I'm saying that it's _bizarre_ to condescendingly point this out _as if it were the crux of contemporary trans-rights debates_. Conservatives and gender-critical feminists _know_ that trans-rights advocates aren't falsely claiming that trans women have XX chromosomes. But the question of what categories epistemically "carve reality at the joints", is _not unrelated_ to the question of which categories to use in policy decisions: the _function_ of sex-segrated bathrooms is to protect females from males, where "females" and "males" are natural clusters in configuration space that it makes sense to want words to refer to.
+
+Even if the thread only explicitly mentioned pronouns and not the noun "woman", in practice, and in the context of elite intellectual American culture in which "trans women are women" is dogma, I don't see any _meaningful_ difference between "you're not standing in defense of truth if you insist on a word, brought explicitly into question, being used with some particular meaning" and "I can define the word 'woman' any way I want." (About which, the Yudkowsky of 2008 had some harsh things to say, as excerpted above.) It's hard to read the Tweets Yudkowsky published as anything other than an attempt to intimidate and delegitimize people who want to use language to reason about sex rather than gender identity. [For example](https://twitter.com/ESYudkowsky/status/1067490362225156096), deeper in the thread, Yudkowsky wrote:
+
+> The more technology advances, the further we can move people towards where they say they want to be in sexspace. Having said this we've said all the facts. Who competes in sports segregated around an Aristotelian binary is a policy question (that I personally find very humorous).
+
+Sure, _in the limit of arbitrarily advanced technology_, everyone could be exactly where they wanted to be in sexpsace. Having said this, we have _not_ said all the facts relevant to decisionmaking in our world, where _we do not have arbitrarily advanced technology_. As Yudkowsky [acknowledges in the previous Tweet](https://twitter.com/ESYudkowsky/status/1067488844122021888), "Hormone therapy changes some things and leaves others constant." The existence of HRT does not take us into the Glorious Transhumanist Future where everyone is the sex they say they are.
+
+Rather, previously sexspace had two main clusters (normal females and males) plus an assortment of tiny clusters corresponding to various [disorders of sex development](https://en.wikipedia.org/wiki/Disorders_of_sex_development), and now it has two additional tiny clusters: females-on-masculinizing-HRT and males-on-feminizing-HRT. Certainly, there are situations where you would want to use "gender" categories that use the grouping {females, males-on-feminizing-HRT} and {males, females-on-masculinizing-HRT}.
+
+But the _reason_ for having sex-segregated sports leagues is because the sport-relevant multivariate trait distributions of female bodies and male bodies are quite different.

+
+Given the empirical reality of the different multivariate trait distributions, "Who are the best athletes _among females_" is a natural question for people to be interested in, and want separate sports leagues to determine. Including male people in female sports leagues undermines the point of having a separate female league.
+
+(Similarly, when conducting [automobile races](https://en.wikipedia.org/wiki/Auto_racing), you want there to be rules enforcing that all competitors have the same type of car for some common-sense-reasonable operationalization of "the same type", because a race between a sports car and a [moped](https://en.wikipedia.org/wiki/Moped) would be mostly measuring who has the sports car, rather than who's the better racer.)
+
+In light of these _empirical_ observations, Yudkowsky's suggestion that an ignorant comittment to an "Aristotelian binary" is the main reason someone might care about the integrity of women's sports, is revealed as an absurd strawman. This just isn't something any scientifically-literate person would write if they had actually thought about the issue _at all_, as contrasted to having _first_ decided (consciously or not) to bolster one's reputation among progressives by dunking on transphobes on Twitter, and wielding one's philosophy knowledge in the service of that political goal. The relevant empirical facts are _not subtle_, even if most people don't have the fancy vocabulary to talk about them in terms of "multivariate trait distributions".
+
+Yudkowsky's pretension to merely have been standing up for the distinction between facts and policy questions isn't credible: if you _just_ wanted to point out that the organization of sports leagues is a policy question rather than a fact (as if anyone had doubted this), why would you throw in the "Aristotelian binary" strawman and belittle the matter as "humorous"? There are a lot of issues that I don't _personally_ care much about, but I don't see anything funny about the fact that other people _do_ care.
+
+(And in this case, the empirical facts are _so_ lopsided, that if we must find humor in the matter, it really goes the other way. Lia Thomas trounces the entire field by _4.2 standard deviations_ (!!), and Eliezer Yudkowsky feels obligated to _pretend not to see the problem?_ You've got to admit, that's a _little_ bit funny.)
+
+Writing out this criticism now, the situation doesn't feel _confusing_, anymore. Yudkowsky was very obviously being intellectually dishonest in response to very obvious political incentives. That's a thing that public intellectuals do. And, again, I agree that the distinction between facts and policy decisions _is_ a valid one, even if I thought it was being selectively invoked here as an [isolated demand for rigor](http://slatestarcodex.com/2014/08/14/beware-isolated-demands-for-rigor/) because of the political context. Coming from _anyone else in the world_, I would have considered the thread fine—a solidly above-average performance, really. I wouldn't have felt confused or betrayed at all. Coming from Eliezer Yudkowsky, it was—confusing.
+
+Because of my hero worship, "he's being intellectually dishonest in response to very obvious political incentives" wasn't in my hypothesis space; I _had_ to assume the thread was an "honest mistake" in his rationality lessons, rather than (what it actually was, what it _obviously_ actually was) hostile political action.
+
+I was physically shaking. I remember going downstairs to confide in a senior engineer about the situation. But if Yudkowsky was _already_ stonewalling his Twitter followers, entering the thread myself didn't seem likely to help. (And I hadn't intended to talk about gender on that account yet, although that seemed less important given the present crisis.)
+
+It seemed better to try to clear this up in private. I still had Yudkowsky's email address. I felt bad bidding for his attention over my gender thing _again_—but I had to do _something_. Hands trembling, I sent him an email asking him to read my ["The Categories Were Made for Man to Make Predictions"](/2018/Feb/the-categories-were-made-for-man-to-make-predictions/), suggesting that it may qualify as an answer to his question about ["a page [he] could read to find a non-confused exclamation of how there's scientific truth at stake"](https://twitter.com/ESYudkowsky/status/1067482047126495232), and that, because I cared very much about correcting what I claim are confusions in my rationalist subculture, that I would be happy to pay up to $1000 for his time, and that, if he liked the post, he might consider Tweeting a link.

+[TODO (Subject: "another offer, $1000 to read a ~6500 word blog post about (was: Re: Happy Price offer for a 2 hour conversation)")]
+
+The monetary offer, admittedly, was awkward: I included another paragraph clarifying that any payment was only to get his attention, and not _quid quo pro_ advertising, and that if he didn't trust his brain circuitry not to be corrupted by money, then he might want to reject the offer on those grounds and only read the post if he expected it to be genuinely interesting.
+
+Again, I realize this must seem weird and cultish to any normal people reading this. (Paying some blogger you follow one grand just to _read_ on of your posts? Who _does_ that?)

+The _issue_ is that category boundaries are not arbitrary (if you care about intelligence being useful): you want to draw your category boundaries such that things in the same category are similar in the respects that you care about predicting/controlling, and you want to spend your [information-theoretically limited budget]() of short words on the simplest and most wide-rangingly useful categories
