+In another post from 4:25 _p.m._ that afternoon, I acknowledged my right-wing influences. You know, you spend nine years reading a lot of ideologically-inconvenient science, all the while thinking, "Oh, this is just interesting science, you know, I'm not going to let myself get _morally corrupted_ by it or anything." And for the last couple years you add in some ideologically-inconvenient political thinkers, too.
+
+But I was still a nice good socially-liberal Free-to-Be-You-and-Me gender-egalitarian individualist person. Because I understood the is–ought distinction—unlike _some_ people—I knew that I could learn from people's _models_ of the world without necessarily agreeing with their _goals_. So I had been trying to learn from the models of these bad people saying the bad things, until one day _the model clicked_. And the model was _terrifying_. And the model had _decision-relevant implications for the people who valued the things that I valued_—
+
+The thing was, I actually _didn't_ think I had been morally corrupted after all! I thought I was actually _really good_ at maintaining the is–ought distinction in my mind. But more people who hadn't followed by exact intellectual trajectory, the mere fact that I was saying, "Wait! Stop! The things that you're doing may not in fact be the optimal things!" made it _look_ like I'd been morally corrupted, and there was no easy way for me to prove otherwise.
+
+So, people probably shouldn't believe me. This was just a little manic episode with no serious implications. Right?
+
+-------
+
+Somewhat awkwardly, I actually had a date scheduled with "Noreen" that evening. The way that happened was, elsewhere on Facebook, earlier, on 7 February, Brent Dill had said that he didn't see the value in the community matchmaking site _reciprocity.io_, and I disagreed, saying that the hang-out matching had been valuable to me, even if the romantic matching was useless for insufficiently high-status males.
+
+"Noreen" had complained: "again with pretending only guys can ever have difficulties getting dates (sorry for this reaction, I just find this incredibly annoying)". I had said that she shouldn't apologize; I usually didn't make that genre of comment, but it seemed thematically appropriate while replying to Brent (who often espoused cynical views about status and social reality).
+
+Incidentally, I added, I was thinking of seeing seeing that new _Hidden Figures_ movie if I could find someone to go with? It turned out that she had already seen it, but we made plans to see _West Side Story_ at the [Castro Theatre](https://www.castrotheatre.com/) instead.
+
+The date was pretty terrible. (Or, maybe I was the only one who categorized it as a "date"? Maybe in her ontology, we were just seeing a movie.) We walked around the Castro for a bit continuing to debate the gender thing, then saw the movie. I was very distracted and couldn't pay attention to the movie at all.
+
+------
+
+I continued to be very distracted the next day, Monday 13 February 2017. I went to my office, but definitely didn't get any dayjob work done.
+
+I made another seven Facebook posts. I'm proud of this one:
+
+> So, unfortunately, I never got very far in the _Daphne Koller and the Methods of Rationality_ book (yet! growth m—splat, AUGH), but one thing I do remember is that many different Bayesian networks can represent the same probability distribution. And the reason I've been running around yelling at everyone for nine months is that I've been talking to people, and we _agree_ on the observations that need to be explained, and yet we explain them in completely different ways. And I'm like, "My network has SO MANY FEWER ARROWS than your network!" And they're like, "Huh? What's wrong with you? Your network isn't any better than the standard-issue network. Why do you care so much about this completely arbitrary property 'number of arrows'? Categories were made for the man, not man for the categories!" And I'm like, "Look, I didn't get far enough in the _Daphne Koller and the Methods of Rationality_ book to understand why, but I'm PRETTY GODDAMNED SURE that HAVING FEWER ARROWS MAKES YOU MORE POWERFUL. YOU DELUSIONAL BASTARDS! HOW CAN YOU POSSIBLY GET THIS WRONG please don't hurt me Oh God please don't hurt me I'm sorry I'm sorry."
+
+That is, when factorizing a joint probability distribution into a Bayesian network, you can do it with respect to any variable ordering you want: a graph with a "wet-streets → rain" edge can represent a set of static observations just as well as a graph with a "rain → wet-streets" edge,[^koller-and-friedman-i] but "unnatural" variable orderings generate a more complicated graph that will give crazy predictions if you interpret it as a _causal_ Bayesian network and use it to predict the results of interventions. Algorithms for learning a network from data prefer graphs with fewer edges as a consequence of Occamian [minimum-message-length epistemology](https://www.lesswrong.com/posts/mB95aqTSJLNR9YyjH/message-length):[^koller-and-friedman-ii] every edge is a [burdensome detail](https://www.lesswrong.com/posts/Yq6aA4M3JKWaQepPJ/burdensome-details) that requires a corresponding [amount of evidence](https://www.lesswrong.com/posts/nj8JKFoLSMEmD3RGp/how-much-evidence-does-it-take) just to [locate it in the space of possibilities](https://www.lesswrong.com/posts/X2AD2LgtKgkRNPj2a/privileging-the-hypothesis).
+
+[^koller-and-friedman-i]: Daphne Koller and Nir Friedman, _Probabilistic Graphical Models: Principles and Techniques_, §3.4.1, "Minimal I-Maps".
+
+[^koller-and-friedman-ii]: Daphne Koller and Nir Friedman, _Probabilistic Graphical Models: Principles and Techniques_, §18.3.5: "Understanding the Bayesian Score".
+
+I thought this shed some light on my recent frustrations. People are pretty observant about what other people are like. If prompted appropriately, they know how to anticipate the ways in which trans women are different from cis women. The part of them that talked just didn't see the problem with trying to represent this knowledge (about physiological males with male-typical interests and personalities whose female gender identities seem closely intertwined with their gynephilic sexuality) using a variable ordering that put "biological sex" closer to last than first. And I just didn't think that was what the causal graph looked like.
+

+
+In another post, I acknowledged my problematic tone:
+
+> I know the arrogance is off-putting! But the arrogance is a really fun part of the æsthetic that I'm really enjoying! Can I get away with it if I mark it as a form of performance art? Like, be really arrogant while exploring ideas, and then later go back and write up the sober serious non-arrogant version?
+
+Someone came to my defense: it was common to have mental blocks about criticizing trans ideology because of the fear that saying anything would hurt one's trans friends and make one an outcast. One way to overcome that block was to get _really angry_ and _visibly having an outburst_, because then people ascribe less agency and culpability to you; it would be clear that you'd cooped up these feelings for a long time because you do understand that they're taboo and unpopular.
+
+The person also said it was hard because it seemed like there were no moderate centrists on gender: you could either be on Team "if you _ever_ want to know what genitals someone has for _any reason_, you are an _evil transphobe_ who should _die_", or Team "trans women are disgusting blokes in dresses who are _invading_ my female spaces for _nefarious purposes_ and we should burn them all".
+
+I added that the worst part is that "trans women are disgusting blokes in dresses who are invading my female spaces for nefarious purposes" view was basically _correct_. It was _phrased_ in a really dismissive manner. But words don't matter! Only predictions matter!
+

+
+The thread on the "Totally Excellent Rationalist Friends" post continued. Someone who I'll call "Kevin" (whom I had never interacted with before or since; my post visibility settings were set to Public) said that the concept of modeling someone based on their gender seemed weird. Correlations with gender were weak enough to be irrelevant after talking with someone for half an hour.
