+I wrote about my frustrations to Scott Alexander of _Slate Star Codex_ fame (Subject: "J. Michael Bailey did nothing wrong"). The immediate result of this is that he ended up including a link to one of Kay Brown's study summaries (and expressing surprise at the claim that non-androphilic trans woman have very high IQs) in his [November links post](https://slatestarcodex.com/2016/11/01/links-1116-site-unseen/), and he [got some pushback even for that](https://slatestarscratchpad.tumblr.com/post/152736458066/hey-scott-im-a-bit-of-a-fan-of-yours-and-i).

+A trans woman named Sophia [commented on one of my real-name blog posts](http://zackmdavis.net/blog/2016/09/wicked-transcendence-ii/), thanking me for the recommendation of _Men Trapped in Men's Bodies_. "It strongly spoke to many of my experiences as a trans woman that I've been treating as unmentionable. (Especially among my many trans friends!)" she wrote. "I think I'm going to start treating them as mentionable."
+
+We struck up an email correspondence (Subject: "Re: [An Algorithmic Lucidity] Please moderate: 'Wicked Transcendence II'"). She had found my blog from the _Slate Star Codex_ blogroll. She had transitioned in July of the previous year at age 35, to universal support. (In Portland, which was perhaps uniquely good in this way.)
+
+I said I was happy for her—probably more so than the average person who says that—but that (despite living in Berkeley, which was perhaps uniquely in contention with Portland for being perhaps uniquely good in this way) there were showstopping contraindications to social transition in my case. It _really mattered_ what order you learn things in. Because the 2016 _Zeitgeist_ had the back of people who model themselves as women who were assigned male at birth (but not people who model themselves as men who love women and want to become what they love), if you _first_ realize, "Oh, I'm trans," and then sucessfully transition, and _then_ read Anne Lawrence, you can say, "Huh, seems plausible that my gender identity was caused by my autogynephilic sexuality rather than the other way around; weird," shrug, and continue living happily ever after. In contrast, I had [already been thinking of myself as autogynephilic (but not "trans") for ten years](/2017/Feb/a-beacon-through-the-darkness-or-getting-it-right-the-first-time/). Even in Portland or Berkeley, you still have to send that coming-out email, and I couldn't claim to have a "gender identity" with a straight face.
+
+She said she would recommend _Men Trapped in Men's Bodies_ on her Facebook wall. I said she was very brave—well, we already knew she was very brave because she _actually transitioned_—but, I suggested, maybe it would be better to wait until [October 11th](https://en.wikipedia.org/wiki/National_Coming_Out_Day) ([October 11th](http://zackmdavis.net/blog/2015/10/october-eleventh/))?
+
+As an afterthought to an explanation of why she thought successfully transitioning is more feasible than I seemed to believe, she suggested a folkloric anti-dysphoria exercise: look at women you see in public, and try to pick out which features /r/gendercritical would call out in order to confirm that she's obviously a man.
+
+I replied that "obviously a man" is unsophisticated. I had been thinking of gendering in terms of [naïve Bayes models](https://www.lesswrong.com/posts/gDWvLicHhcMfGmwaK/conditional-independence-and-naive-bayes): you observe some features, use those to assign (probabilities of) category membership, and then use category membership to make predictions about whatever other features you might care about but can't immediately observe. Sure, it's possible for an attempted clocking to be mistaken, and you can have gender categories such that AGP trans women aren't "men", but they're still not drawn from anything close to the same distribution as cis women.
+
+She replied with an information-theoretic analysis of passing (which I would [later adapt into a guest post with her gracious permission](/2018/Oct/the-information-theory-of-passing/)). If the base rate of AGP transsexualism in Portland was 0.1%, someone would need log<sub>2</sub>(99.9%/0.1%) ≈ 9.96 ≈ 10 bits of evidence to clock her as trans. Thus, the prospect of passing in naturalistic settings is a different question from whether there exists evidence that a trans person is trans. There _is_ evidence—but who cares, as long as it's comfortably under 10 bits?
+
+I agreed that for most people in most everyday situations it probably didn't matter. _I_ cared because I was a computational philosophy of gender nerd, I said, [linking to a program I had written](https://github.com/zackmdavis/Persongen/blob/8fc03d3173/src/main.rs) to simulate sex classification based on personality, using data from [a paper about sex differences in the "facets" underlying the Big Five personality traits](http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3149680/). Sophia was impressed, but had some cutting methodological critiques. The paper had given the residuals of each facet against the other, so I assumed you could sample one, and then use the residual stats to get a "diff" from one to the other. Sophia pointed out that you can't actually use residuals for sampling like that, because the actual distribution of the residual was highly dependent on the first facet. Given an unusually high value for one facet, taking the overall residual stats as independent would imply that the other facet was equally likely to be higher or lower, which was absurd.

+
+I messaged an _alumna_ of my [App Academy](https://www.appacademy.io/) class of November 2013. I remembered that on the first day of App Academy, she had asked about the harrassment policy, to which the founder/instructor hesitated and promised to get back to her; apparently, it had never come up before. (This was back when App Academy was still cool and let you sleep on the floor if you wanted.) Later in the cohort, she started a quarrel with another student (an 18-year-old boy, in contrast to most attendees already having a college degree) over the offensive political implications of something he had said; someone else pointed out in his defense that he was young. (Young enough, or autistic enough, not to have been trained not to say anything that could be construed as anti-feminist in a professional setting?)
+
+In short, I wanted to consult her feminism expertise; she seemed like the kind of person who might have valuable opinions on whether men could become women by means of saying so. "[O]n the one hand, I'm glad that other people get to live my wildest fantasy", I said, after explaining the problem, "but on the other hand, maaaaaybe we shouldn't actively encourage people to take their fantasies quite this literally? Maybe you don't want people like me in your bathroom for the same reason you're annoyed by men's behavior on trains?"
+
+She asked if I had read _The Man Who Would Be Queen_. (I had.) She said she personally didn't care about bathrooms.
+
+She had also read a lot about related topics (in part because of her own history as a gender-nonconforming child), but that this area of it (autogynephilia, _&c._) was difficult to talk about except from one's lived experience because "the public narrative is very ... singular". She thought that whether and how dysphoria was related to eroticism could be different for different people, but thought that the singular narrative had been culturally important, in the same way as the "gay is not a choice" narrative had been, letting people with less privilege live in a way that makes them happy with less of a penalty. (She did empathize with concern about kids being encouraged to transition early; given the opportunity to go to school as a boy at age 7, she would have taken it, and it would have been the wrong path.)
