+In ["Autogenderphilia Is Common And Not Especially Related To Transgender"](https://slatestarcodex.com/2020/02/10/autogenderphilia-is-common-and-not-especially-related-to-transgender/), Scott Alexander, based on his eyeballing data from the 2020 _Slate Star Codex_ reader survey, proposes what he calls a "very boring" hypothesis of "autogenderphilia": "if you identify as a gender, and you're attracted to that gender, it's a natural leap to be attracted to yourself being that gender."
+
+Explaining my view on this "boring hypothesis" turns out to be a surprisingly challenging writing task,
+
+because I suspect my actual crux comes down to a [Science _vs._ Bayescraft](https://www.lesswrong.com/posts/viPPjojmChxLGPE2v/the-dilemma-science-or-bayes) thing, where I'm self-conscious about my answer [sounding weirdly overconfident on non-empirical grounds](https://slimemoldtimemold.com/2022/01/11/reality-is-very-weird-and-you-need-to-be-prepared-for-that/) to someone who doesn't already share my parsimony intuitions—but, frankly, I also expect my parsiony intuitions to actually get the right answer in the real world, and modesty/[Outside View](https://www.lesswrong.com/posts/FsfnDfADftGDYeG4c/outside-view-as-conversation-halter)/[Caution on Bias Arguments](https://slatestarcodex.com/2019/07/17/caution-on-bias-arguments/) to get the wrong answer.
+
+If we have a big causal graph with C at the root (E₂ ← E₁ ← C → E₃ ...) with real-valued variables, and someone proposes a theory about what happens to the E_i when C is between 2 and 3 or between 5 and 6 or above 12, that's very unparsimonious: why would such a discontinuous hodge-pause of values for the cause, have consistent effects?
+
+In my worldview, "gender" (as the thing trans women and cis women have in common) looks like a hodge-podge as far as biology is concerned. (It can be real socially to the extent that people believe it's real and act accordingly, which creates the relevant conditional indpendence structure in their social behavior—but sexuality looks more "biological" than "social".)
+
+In my ontology of how-the-world-works, this is _not_ a boring hypothesis. In my ontology, this is a shockingly weird hypothesis, where I can read the English words, but I have a lot of trouble parsing the English words into a model in my head, because the antecedent, "If you identify as a gender, and you're attracted to that gender, then ...", already takes a massive prior probability penalty, because that category is multiply disjunctive over the natural space of biological similarities: you're grouping together lesbians _and_ gay men _and_ heterosexual males with a female gender identity _and_ heterosexual females with a male gender identity, and trying to make claim about what members of this group are like.
+
+What do lesbians, and gay men, and heterosexual males with a female gender identity, and heterosexual females with a male gender identity have in common, such that we expect to make useful inductive inferences about this group?
+
+Well, they're all human; that buys you a _lot_ of similarities!
+
+But your hypothesis isn't about humans-in-general, it's specifically about people who identify "identify as a gender, and [are] attracted to that gender".
+
+So the question becomes, what do lesbians, and gay men, and heterosexual males with a female gender identity, and heterosexual females with a male gender identity have in common, that they _don't_ have in common with heterosexual males and females without a cross-sex identity?
+
+Well, sociologically, they're demographically eligible for our Society's LGBTQIA+ political coalition, living outside of what traditional straight Society considers "normal." That shared _social_ experience could induce similarities.
+
+But your allegedly boring hypothesis is not appealing to a shared social experience; you're saying "it's a natural leap to be attracted ...", appealing to the underlying psychology of sexual attraction in a way that doesn't seem very culture-sensitive. In terms of the underlying psychology of sexual attraction, what do lesbians, and gay men, and heterosexual males with a female gender identity, and heterosexual females with a male gender identity have in common, that they _don't_ have in common with heterosexual males and females without a cross-sex identity?
+
+I think the answer here is just "Nothing."
+
+Oftentimes I want to categorize people by sex, and formulate hypotheses of the form, "If you're female/male, then ...". This is a natural category that buys me [predictions about lots of stuff](https://en.wikipedia.org/wiki/Sex_differences_in_humans).
+
+_Sometimes_ I want to categorize people by gynephilic/androphilic sexual orientation: this helps me make sense of how [lesbians are masculine compared to other females, and gay men are feminine compared to other males](http://unremediatedgender.space/papers/lippa-gender-related_traits_in_gays.pdf). (That is, it looks like _homosexuality_—not the kind of trans people we know—is probably a brain intersex condition, and the extreme right tail of homosexuality accounts for the kind of trans people we mostly don't know.)
+
+But even so, when thinking about sexual orientation, I'm usually making a _within_-sex comparison: contrasting how gay men are different from ordinary men, how lesbians are different from ordinary women. I don't usually have much need to reason about "people who are attracted to the sex that they are" as a group, because that group splits cleanly into gay men and lesbians, which have a _different_ [underlying causal structure](https://www.lesswrong.com/posts/vhp2sW6iBhNJwqcwP/blood-is-thicker-than-water). "LGBT" (...QUIA+) makes sense as a _political coalition_ (who have a shared interest in resisting the oppression of traditional sexual morality), not because the L and the G and the B and the T are the same kind of people who live common lives. (Indeed, as you know, I don't even think the "T" is one thing.)
+
+And so, given that I _already_ don't have much use for "if you are a sex, and you're attracted to that sex" as a category of analytical interest, because I think gay men and lesbians are different things that need to be studied separately, "if you identify as a gender, and you're attracted to that gender" (with respect to "gender", not sex) comes off even worse. What causal mechanism could that possibly, _possibly_ correspond to?!
+
+Again, I'm self-conscious that to someone who doesn't already share my worldview, this seems dogmatically non-empirical—here I'm telling you why I can't take your theory seriously without even _addressing_ the survey data that you think your theory can explain that mine can't. Is this not a scientific sin? What is this "but causal mechanisms" technobabble, in the face of _empirical_ survey data, huh?
+
+The thing is, I don't see my theory as _making_ particularly strong advance predictions one way or the other on how cis women or gay men will respond to the "imagine being him/her" questions.
+
+The _reason_ I believe autogynephlia (in males) "is a thing" and causally potent to transgenderedness in the first place, is not because trans women gave a mean Likert response of 3.4 on someone's survey, but as the output of my brain's inductive inference algorithms operating on a _massive_ confluence of a [real-life experiences](http://unremediatedgender.space/2021/May/sexual-dimorphism-in-the-sequences-in-relation-to-my-gender-problems/) and observations in a naturalistic setting. (That's how people [locate](https://www.lesswrong.com/posts/MwQRucYo6BZZwjKE7/einstein-s-arrogance) survey questions are worth asking in the first place, out of the vastness of possible survey questions.)
+
+If you look at what trans women say _to each other_ when the general public isn't looking, you see the same stories (examples from /r/MtF: ["I get horny when I do 'girl things'. Is this a fetish?"](https://www.reddit.com/r/MtF/comments/qy4ncb/i_get_horny_when_i_do_girl_things_is_this_a_fetish/), ["Is the 'body swap' fetish inherently pre-trans?"](https://www.reddit.com/r/MtF/comments/q8k57y/is_the_body_swap_fetish_inherently_pretrans/), ["Could it be a sex fantasy?"](https://www.reddit.com/r/MtF/comments/rd78kw/could_it_be_a_sex_fantasy/), _&c._, _ad infinitum_) over and over and over again.
+
+Without making any pretentions whatsoever to rigor or Science, but _just_ looking at the world and trying to describe it in words, I think there is clearly a _thing_ here. When I look at what women write, and when I look at what gay men write, I don't see the _same thing_.
+
+After observing this kind of pattern in the world, it's a good idea to do surveys to get some numbers and data to help you learn more about what's going on with the pattern. There's clearly a thing here, but is the thing being generated by a visible minority, or is it actually a majority? When [82% of /r/MtF users say Yes to "Did you have a gender/body swap/transformation "fetish" (or similar) before you realised you were trans?"](https://www.reddit.com/r/MtF/comments/89nw0w/did_you_have_a_genderbody_swaptransformation/), that makes me think it's a majority.
+
+When you pose a vaguely similar question to a different group, are you measuring the same real-world phenomenon in that other group? Maybe, but I think this is very nonobvious.
+
+And it contexts where it's not politically inconvenient for you, _you agree with me_: you wrote about this methodological issue in ["My IRB Nightmare"](https://slatestarcodex.com/2017/08/29/my-irb-nightmare/), expressing skepticism about a screening test for bipolar disorder:
