+[TODO: sneering at post-rats; David Xu interprets criticism of Eliezer as me going "full post-rat"?!
+
+> Also: speaking as someone who's read and enjoyed your LW content, I do hope this isn't a sign that you're going full post-rat. It was bad enough when QC did it (though to his credit QC still has pretty decent Twitter takes, unlike most post-rats).

+
+> I'm curious what might count for you as a crux about this; candidate cruxes I could imagine include: whether some categories facilitate inferences that _do_, on the whole, cause more harm than benefit, and if so, whether it is "rational" to rule that such inferences should be avoided when possible, and if so, whether the best way to disallow a large set of potential inferences is [to] proscribe the use of the categories that facilitate them—and if _not_, whether proscribing the use of a category in _public communication_ constitutes "proscribing" it more generally, in a way that interferes with one's ability to perform "rational" thinking in the privacy of one's own mind.
+>
+> That's four possible (serial) cruxes I listed, one corresponding to each "whether".
+
+I reply: on the first and second cruxes, concerning whether some categories facilitate inferences that cause more harm than benefit on the whole and whether they should be avoided when possible, I ask: harm _to whom?_ Not all agents have the same utility function! If some people are harmed by other people making certain probabilistic inferences, then it would seem that there's a _conflict_ between the people harmed (who prefer that such inferences be avoided if possible), and people who want to make and share probabilistic inferences about reality (who think that that which can be destroyed by the truth, should be).
+
+On the third crux, whether the best way to disallow a large set of potential inferences is to proscribe the use of the categories that facilitate them: well, it's hard to be sure whether it's the _best_ way: no doubt a more powerful intelligence could search over a larger space of possible strategies than me. But yeah, if your goal is to _prevent people from noticing facts about reality_, then preventing them from using words that refer those facts seems like a pretty effective way to do it!
+
+On the fourth crux, whether proscribing the use of a category in public communication constitutes "proscribing" in a way that interferes with one's ability to think in the privacy of one's own mind: I think this is mostly true for humans. We're social animals. To the extent that we can do higher-grade cognition at all, we do it using our language faculties that are designed for communicating with others. How are you supposed to think about things that you don't have words for?
+
+Xu continues:
+
+> I could have included a fifth and final crux about whether, even _if_ The Thing In Question interfered with rational thinking, that might be worth it; but this I suspect you would not concede, and (being a rationalist) it's not something I'm willing to concede myself, so it's not a crux in a meaningful sense between us (or any two self-proclaimed "rationalists").
+>
+> My sense is that you have (thus far, in the parts of the public discussion I've had the opportunity to witness) been behaving as though the _one and only crux in play_—that is, the True Source of Disagreement—has been the fifth crux, the thing I refused to include with the others of its kind. Your accusations against the caliphate _only make sense_ if you believe the dividing line between your behavior and theirs is caused by a disagreement as to whether "rational" thinking is "worth it"; as opposed to, say, what kind of prescriptions "rational" thinking entails, and which (if any) of those prescriptions are violated by using a notion of gender (in public, where you do not know in advance who will receive your communications) that does not cause massive psychological damage to some subset of people.
+>
+> Perhaps it is your argument that all four of the initial cruxes I listed are false; but even if you believe that, it should be within your set of ponderable hypotheses that people might disagree with you about that, and that they might perceive the disagreement to be _about_ that, rather than (say) about whether subscribing to the Blue Tribe view of gender makes them a Bad Rationalist, but That's Okay because it's Politically Convenient.
+>
+> This is the sense in which I suspect you are coming across as failing to properly Other-model.
+
+After everything I've been through over the past six years, I'm inclined to think it's not a "disagreement" at all.
+
+It's a _conflict_. I think what's actually at issue is that, at least in this domain, I want people to tell the truth, and the Caliphate wants people to not tell the truth. This isn't a disagreement about rationality, because telling the truth _isn't_ rational _if you don't want people to know things_.
+
+At this point, I imagine defenders of the Caliphate are shaking their heads in disappointment at how I'm doubling down on refusing to Other-model. But—_am_ I? Isn't this just a re-statement of Xu's first proposed crux, except reframed as a "values difference" rather than a "disagreement"?
+
+Is the problem that my use of the phrase "tell the truth" (which has positive valence in our culture) functions to sneak in normative connotations favoring "my side"?
+
+Fine. Objection sustained. I'm happy to use to Xu's language: I think what's actually at issue is that, at least in this domain, I want to facilitate people making inferences (full stop), and the Caliphate wants to _not_ facilitate people making inferences that, on the whole, cause more harm than benefit. This isn't a disagreement about rationality, because facilitating inferences _isn't_ rational _if you don't want people to make inferences_ (for example, because they cause more harm than benefit).
+
+Better? Perhaps, to some 2022-era rats and EAs, this formulation makes my position look obviously in the wrong: I'm saying that I'm fine with my inferences _causing more harm than benefit_ (!). Isn't that monstrous of me? Why would someone do that?
+
+One of the better explanations of this that I know of was (again, as usual) authored by Yudkowsky in 2007, in a post titled ["Doublethink (Choosing to be Biased)"](https://www.lesswrong.com/posts/Hs3ymqypvhgFMkgLb/doublethink-choosing-to-be-biased).
+
+The Yudkowsky of 2007 starts by quoting a passage from George Orwell's _1984_, in which O'Brien (a loyal member of the ruling Party in the totalitarian state depicted in the novel) burns a photograph of Jones, Aaronson, and Rutherford (former Party leaders whose existence has been censored from the historical record). Immediately after burning the photograph, O'Brien denies that it ever existed.
+
+The Yudkowsky of 2007 continues—it's again worth quoting at length—
+
+> What if self-deception helps us be happy? What if just running out and overcoming bias will make us—gasp!—_unhappy?_ Surely, _true_ wisdom would be _second-order_ rationality, choosing when to be rational. That way you can decide which cognitive biases should govern you, to maximize your happiness.
+>
+> Leaving the morality aside, I doubt such a lunatic dislocation in the mind could really happen.
+>
+> [...]
+>
+> For second-order rationality to be genuinely _rational_, you would first need a good model of reality, to extrapolate the consequences of rationality and irrationality. If you then chose to be first-order irrational, you would need to forget this accurate view. And then forget the act of forgetting. I don't mean to commit the logical fallacy of generalizing from fictional evidence, but I think Orwell did a good job of extrapolating where this path leads.
+>
+> You can't know the consequences of being biased, until you have already debiased yourself. And then it is too late for self-deception.
+>
+> The other alternative is to choose blindly to remain biased, without any clear idea of the consequences. This is not second-order rationality. It is willful stupidity.
+>
+> [...]
+>
+> One of chief pieces of advice I give to aspiring rationalists is "Don't try to be clever." And, "Listen to those quiet, nagging doubts." If you don't know, you don't know _what_ you don't know, you don't know how _much_ you don't know, and you don't know how much you _needed_ to know.
+>
+> There is no second-order rationality. There is only a blind leap into what may or may not be a flaming lava pit. Once you _know_, it will be too late for blindness.
+
+Looking back on this from 2022, the only criticism I have is that Yudkowsky was too optimistic to "doubt such a lunatic dislocation in the mind could really happen." In some ways, people's actual behavior is _worse_ than what Orwell depicted. The Party of Orwell's _1984_ covers its tracks: O'Brien takes care to burn the photograph _before_ denying memory of it, because it would be _too_ absurd for him to act like the photo had never existed while it was still right there in front of him.
+
+In contrast, Yudkowsky's Caliphate of the current year _doesn't even bother covering its tracks_. Turns out, it doesn't need to! People just don't remember things!
+
+The [flexibility of natural language is a _huge_ help here](https://www.lesswrong.com/posts/MN4NRkMw7ggt9587K/firming-up-not-lying-around-its-edge-cases-is-less-broadly). If the caliph were to _directly_ contradict himself in simple, unambiguous language—to go from "Oceania is not at war with Eastasia" to "Oceania is at war with Eastasia" without any acknowledgement that anything had changed—_then_ too many people might notice that those two sentences are the same except that one has the word _not_ in it. What's a caliph to do, if he wants to declare war on Eastasia without acknowledging or taking responsibility for the decision to do so?
+
+The solution is simple: just—use more words! Then if someone tries to argue that you've _effectively_ contradicted yourself, accuse them of being uncharitable and failing to model the Other. You can't lose! Anything can be consistent with anything if you apply a sufficiently charitable reading; whether Oceania is at war with Eastasia depends on how you choose to draw the category boundaries of "at war."
+
+Thus, O'Brien should envy Yudkowsky: burning the photograph turns out to be unnecessary! ["Changing Emotions"](https://www.lesswrong.com/posts/QZs4vkC7cbyjL9XA9/changing-emotions) is _still up_ and not retracted, but that didn't stop the Yudkowsky of 2016 from pivoting to ["at least 20% of the ones with penises are actually women"](https://www.facebook.com/yudkowsky/posts/10154078468809228) when that became a politically favorable thing to say. I claim that these posts _effectively_ contradict each other. The former explains why men who fantasize about being women are _not only_ out of luck given forseeable technology, but _also_ that their desires may not even be coherent (!), whereas the latter claims that men who wish they were women may, in fact, _already_ be women in some unspecified psychological sense.
+
+_Technically_, these don't _strictly_ contradict each other: I can't point to a sentence from each that are the same except one includes the word _not_. (And even if there were such sentences, I wouldn't be able to prove that the other words were being used in the same sense in both sentences.) One _could_ try to argue that "Changing Emotions" is addressing cis men with a weird sex-change fantasy, whereas the "ones with penises are actually women" claim was about trans women, which are a different thing.
+
+_Realistically_ ... no. These two posts _can't_ both be right. In itself, this isn't a problem: people change their minds sometimes, which is great! But when people _actually_ change their minds (as opposed to merely changing what they say in public for political reasons), you expect them to be able to _acknowledge_ the change, and hopefully explain what new evidence or reasoning brought them around. If they can't even _acknowledge the change_, that's pretty Orwellian, like O'Brien trying to claim that the photograph is of different men who just coincidentally happen to look like Jones, Aaronson, and Rutherford.
+
+And if a little bit of Orwellianism on specific, narrow, highly-charged topics might be forgiven—because everyone else in your Society is doing it, and you would be punished for not playing along, an [inadequate equilibrium](https://equilibriabook.com/) that no one actor has the power to defy—might we not expect the father of the "rationalists" to stand his ground on the core theses of his ideology, like whether telling the truth is good?
+
+I guess not! ["Doublethink (Choosing to be Biased)"](https://www.lesswrong.com/posts/Hs3ymqypvhgFMkgLb/doublethink-choosing-to-be-biased) is _still up_ and not retracted, but that didn't stop Yudkowsky from [endorsing everything Xu said](https://twitter.com/ESYudkowsky/status/1436025983522381827) about "whether some categories facilitate inferences that _do_, on the whole, cause more harm than benefit, and if so, whether it is 'rational' to rule that such inferences should be avoided when possible" being different cruxes than "whether 'rational' thinking is 'worth it'".
+
+I don't doubt Yudkowsky could come up with some clever casuistry why, _technically_, the text he wrote in 2007 and the text he endorsed in 2021 don't contradict each other. But _realistically_ ... again, no.
+
+[TODO: elaborate on how 2007!Yudkowsky and 2021!Xu are saying the opposite things if you just take a plain-language reading and consider, not whether individual sentences can be interpreted as "true", but what kind of _optimization_ the text is doing to the behavior of receptive readers]
