+I guess by now the branch is as close to settled as it's going to get? Alexander ended up [adding an edit note to the end of "... Not Man to the Categories" in December 2019](https://archive.is/1a4zV#selection-805.0-817.1), and Yudkowsky would [go on to clarify his position on the philosophy of language in September 2020](https://www.facebook.com/yudkowsky/posts/10158853851009228). So, that's nice. But I will confess to being quite disappointed that the public argument-tree evaluation didn't get much further, much faster? The thing you have understand about this whole debate is—
+
+_I need the correct answer in order to decide whether or not to cut my dick off_. As I've said, I _currently_ believe that cutting my dick off would be a _bad_ idea. But that's cost–benefit judgement call based on many _contingent, empirical_ beliefs about the world. I'm obviously in the general _reference class_ of males who are getting their dicks cut off these days, and a lot of them seem to be pretty happy about it! I would be much more likely to go through with transitioning if I believed different things about the world—if I thought my beautiful pure sacred self-identity thing were a brain-intersex condition, or if I still believed in my teenage psychological-sex-differences denialism (such that there would be _axiomatically_ no worries about fitting with "other" women after transitioning), or if I were more optimistic about the degree to which HRT and surgeries approximate an actual sex change.

+In that November 2018 Twitter thread, [Yudkowsky wrote](https://archive.is/y5V9i):
+
+> _Even if_ somebody went around saying, "I demand you call me 'she' and furthermore I claim to have two X chromosomes!", which none of my trans colleagues have ever said to me by the way, it still isn't a question-of-empirical-fact whether she should be called "she". It's an act."

+This seems to suggest that gender pronouns in the English language as currently spoken don't have effective truth conditions. I think this is false _as a matter of cognitive science_. If someone told you, "Hey, you should come meet my friend at the mall, she is really cool and I think you'll like her," and then the friend turned out to look like me (as I am now), _you would be surprised_. (Even if people in Berkeley would socially punish you for _admitting_ that you were surprised.) The "she ... her" pronouns would prompt your brain to _predict_ that the friend would appear to be female, and that prediction would be _falsified_ by someone who looked like me (as I am now). Pretending that the social-norms dispute is about chromosomes was a _bullshit_ [weakmanning](https://slatestarcodex.com/2014/05/12/weak-men-are-superweapons/) move on the part of Yudkowsky, [who had once written that](https://www.lesswrong.com/posts/qNZM3EGoE5ZeMdCRt/reversed-stupidity-is-not-intelligence) "[t]o argue against an idea honestly, you should argue against the best arguments of the strongest advocates[;] [a]rguing against weaker advocates proves _nothing_, because even the strongest idea will attract weak advocates." Thanks to the skills I learned from Yudkowsky's _earlier_ writing, I wasn't dumb enough to fall for it, but we can imagine someone otherwise similar to me who was, who might have thereby been misled into making worse life decisions.

+If this "rationality" stuff is useful for _anything at all_, you would _expect_ it to be useful for _practical life decisions_ like _whether or not I should cut my dick off_.
