[Although](http://www.overcomingbias.com/author/hal-finney) [technically](http://www.overcomingbias.com/author/james-miller) [a](http://www.overcomingbias.com/author/david-j-balan) [group](http://www.overcomingbias.com/author/andrew) [blog](http://www.overcomingbias.com/author/anders-sandberg), the vast majority of posts on _Overcoming Bias_ were by Robin Hanson or Eliezer Yudkowsky. I was previously acquainted in passing with Yudkowsky's [writing about future superintelligence](https://web.archive.org/web/20200217171258/https://yudkowsky.net/obsolete/tmol-faq.html). (I had [mentioned him in my Diary once in 2005](/ancillary/diary/42/), albeit without spelling his name correctly.) Yudkowsky was now using _Overcoming Bias_ and the medium of blogging [to generate material for a future book about rationality](https://www.lesswrong.com/posts/vHPrTLnhrgAHA96ko/why-i-m-blooking). Hanson's posts I could take or leave, but Yudkowsky's sequences of posts about rationality (coming out almost-daily through early 2009, eventually totaling hundreds of thousands of words) were _amazingly great_, [drawing on fields](https://www.lesswrong.com/posts/tSgcorrgBnrCH8nL3/don-t-revere-the-bearer-of-good-info) from [cognitive](https://www.lesswrong.com/posts/2ftJ38y9SRBCBsCzy/scope-insensitivity) [psychology](https://www.lesswrong.com/posts/R8cpqD3NA4rZxRdQ4/availability) to [evolutionary biology](https://www.lesswrong.com/s/MH2b8NfWv22dBtrs8) to explain the [mathematical](https://www.readthesequences.com/An-Intuitive-Explanation-Of-Bayess-Theorem) [principles](https://www.readthesequences.com/A-Technical-Explanation-Of-Technical-Explanation) [governing](https://www.lesswrong.com/posts/eY45uCCX7DdwJ4Jha/no-one-can-exempt-you-from-rationality-s-laws) _how intelligence works_—[the reduction of "thought"](https://www.lesswrong.com/posts/p7ftQ6acRkgo6hqHb/dreams-of-ai-design) to [_cognitive algorithms_](https://www.lesswrong.com/posts/HcCpvYLoSFP4iAqSz/rationality-appreciating-cognitive-algorithms). Intelligent systems that use [evidence](https://www.lesswrong.com/posts/6s3xABaXKPdFwA3FS/what-is-evidence) to construct [predictive](https://www.lesswrong.com/posts/a7n8GdKiAZRX86T5A/making-beliefs-pay-rent-in-anticipated-experiences) models of the world around them—that have "true" "beliefs"—can _use_ those models to compute which actions will best achieve their goals. You simply [won't believe how much this blog](https://www.lesswrong.com/posts/DXcezGmnBcAYL2Y2u/yes-a-blog) will change your life; I would later frequently [joke](https://en.wiktionary.org/wiki/ha_ha_only_serious) that Yudkowsky rewrote my personality over the internet.
-(The blog posts later got edited and collected into a book, [_Rationality: From AI to Zombies_](https://www.amazon.com/Rationality-AI-Zombies-Eliezer-Yudkowsky-ebook/dp/B00ULP6EW2), but I continue to say "the Sequences" because I _hate_ the gimmicky "AI to Zombies" subtitle—it makes it sound like a commercial book optimized to sell copies, rather than something competing for the same niche as the Bible or the Koran—_the book_ that explains what your life should be about.)

There are a few things about me that I need to explain before I get into the topic-specific impact the blog had on me.
(I _still_ don't want to be blogging about this, but unfortunately, it actually turns out to be central to the intellectual–political project I've been singlemindedly focused on for the past four years because [somebody has to and no one else will](https://unsongbook.com/chapter-6-till-we-have-built-jerusalem/))
-—my _favorite_—and basically only—masturbation fantasy has always been some variation on me getting magically transformed into a woman. I ... need to write more about the phenomenology of this. In the meantime, just so you know what I'm talking about, the relevant TVTrope is ["Man, I Feel Like a Woman."](https://tvtropes.org/pmwiki/pmwiki.php/Main/ManIFeelLikeAWoman) (Or search "body swap" on PornHub.

-So, there was that erotic thing, which I was pretty ashamed of at the time, and _of course_ knew that I must never tell a single soul about. (It would have been about three years since the fantasy started that I even worked up the bravery to [tell my Diary about it](/ancillary/diary/53/#first-agp-confession).)
+(The first segment of my pen surname is a legacy of middle-school friends letting me borrow some of the [Ranma ½](https://en.wikipedia.org/wiki/Ranma_%C2%BD) graphic novels (about a young man cursed to transform into a woman on exposure to cold water) just _before_ puberty kicked in, but I have no way of computing the counterfactual to know whether that had a causal influence.)
-But within a couple years, I also developed this beautiful pure sacred self-identity thing that would persist for years, where I started having a lot of _non_-sexual thoughts about being female. (Or at least not-identifiably-male.) Just—little day-to-day thoughts, little symbolic gestures.

Or how, at University, I tried to go by my [first-and-middle-initials](https://en.wikipedia.org/wiki/List_of_literary_initials) because I wanted a gender-neutral [byline](https://en.wikipedia.org/wiki/Byline), and I wanted what people called me in real life to be the same as my byline—even if, obviously, I didn't expect people to not-notice which sex I am in real life because _that would be crazy_.
-(This attempted nickname-change turned out to be a terrible idea for several reasons: first, my particular pair of real-life initials never really "felt like a name" even to me (as contrasted to something like "C.J.", which feels like a name because it has a _J_ in it); second, I found it incredibly psychologically stressful for some people to know me by one name, and people I knew before to know me by another, and I didn't have the guts to nag people in the latter group to switch for something that didn't feel like a name even to me; third, the "gender-neutral byline" rationale almost certainly didn't hold up in practice because my real first initial (not _M._; this blog is under a pen name) is a high-Scrabble-score letter that begins one high-frequency boy name (top 200 in the [1990 Census list](https://www.census.gov/topics/population/genealogy/data/1990_census/1990_census_namefiles.html)), and no high-frequency girl names (the most popular candidates trailing my ugly boy-name in frequency by an order of magnitude). But it was the _principle!_)

At the time, I had _no reason to invent the hypothesis_ that I might somehow literally be a woman in some unspecified psychological sense. I knew I was a boy _because_ boys are the ones with penises. That's what the word _means_. I was a boy who had a weird _sex fantasy_ about being a girl. That was just the obvious ordinary straightforward plain-language description of the situation. It _never occured to me_ to couch it in the language of "dysphoria", or actually possessing some innate "gender". The beautiful pure sacred self-identity thing was about identifying _with_ women, not identifying _as_ a woman—roughly analogous to how a cat lover might be said to "identify with" cats, without claiming to somehow _be_ a cat, because _that would be crazy_.
-[It was while browsing _Wikipedia_ in 2006 that I encountered the obvious and perfect word for my thing](/2017/Feb/a-beacon-through-the-darkness-or-getting-it-right-the-first-time/)—_autogynephilia_, from the Greek for "[love of](https://en.wiktionary.org/wiki/-philia) [oneself as](https://en.wiktionary.org/wiki/auto-#English) [a woman](https://en.wiktionary.org/wiki/gyno-)." I was actually surprised that it turned out to have been coined in the context of a theory (by Canadian sexologist Ray Blanchard) that it was the root cause of one of two types of male-to-female transsexualism.
+[It was while browsing _Wikipedia_ in 2006 that I encountered the obvious and perfect word for my thing](/2017/Feb/a-beacon-through-the-darkness-or-getting-it-right-the-first-time/)—_autogynephilia_, from the Greek for "[love of](https://en.wiktionary.org/wiki/-philia) [oneself as](https://en.wiktionary.org/wiki/auto-#English) [a woman](https://en.wiktionary.org/wiki/gyno-)." I was actually surprised that it turned out to have been coined in the context of a theory (by Canadian sexologist Ray Blanchard) that it was the root cause of one of two types of male-to-female transsexualism.
You see, a very important feature of my gender-related thinking at the time was that I was growing very passionate about—well, in retrospect I call it _psychological-sex-differences denialism_, but at the time I called it _antisexism_. Where sometimes people in the culture would make claims about how women and men are psychologically different, and of course I knew this was _bad and wrong_. Therefore the very idea of transsexualism was somewhat suspect insofar as it necessarily depends on the idea that women and men are psychologically different (in order for it to be possible to be in the "wrong" body).
-So while I was certainly glad to learn that there was an obvious and perfect word for _my thing_, I mostly just stole the word (whose referent and meaning I thought was self-explanatory from the common Greek roots) without paying any further attention to the Blanchard taxonomy or the idea that _I_ might somehow be transgender.

So, you know, as part of my antisexism, I read a lot about feminism. I remember checking out _The Feminine Mystique_ and Susan Faludi's _Backlash_ from the school library. Before I found my internet-home on _Overcoming Bias_, I would read the big feminist blogs—_Pandagon_, _Feministe_, _Feministing_. The one time I special-ordered a book at the physical Barnes & Noble before I turned 18 and got my own credit card and could order books online, it was _Feminist Intepretations of Ayn Rand_.
(In retrospect, it's notable how _intellectualized_ all of this was—my pro-feminism was an ideological matter between me and my books, rather than arising from any practical need. It's not like I had disproportionately female friends or whatever—I mean, to the extent that I had any friends and not just books.)
-It also seems like a pretty obvious guess that there must have been _some sort of causal relationship_ between my antisexism and the erotic and beautiful-pure-sacred-self-identity things.
-
-True, the [blank slate doctrine](/2020/Apr/book-review-human-diversity/#blank-slate) has been ideologically fashionable my entire life. In the sense that progressivism has been [likened to a nontheistic state religion](https://www.unqualified-reservations.org/2007/09/how-dawkins-got-pwned-part-1/)—uh, bear with me for a moment—I was a _very_ religious teenager.

-I remember being in the Crown College library at the University in Santa Cruz in 2007, reading Robert Wright's _The Moral Animal_ (because it had been on [Yudkowsky's old book-recommendations list](https://web.archive.org/web/20200118114912/https://yudkowsky.net/obsolete/bookshelf.html)), and being _aghast_ at how openly, brazenly _sexist_ it was.
+I have a vague memory of being in the Crown College library at the University in Santa Cruz in 2007, reading Robert Wright's _The Moral Animal_ (because it had been on [Yudkowsky's old book-recommendations list](https://web.archive.org/web/20200118114912/https://yudkowsky.net/obsolete/bookshelf.html)), and being _aghast_ at how openly, brazenly _sexist_ it was.
(That is, with respect to what I considered _sexist_ at the time. I wish there was some way to know what my teenage self would think of my current self's writing, which is at least as "bad" as Wright and plausibly worse. Maybe if the whole benevolent-superintelligence thing my robot cult always talks about ever works out, I'll be able to kick off a limited-scope [ancestor-simulation](https://www.simulation-argument.com/simulation.html) to find out. In the meantime, if you're offended, I'd love it if you could let me know in the comments exactly how much and why! [Personal identity doesn't actually exist](https://www.lesswrong.com/posts/RLScTpwc5W2gGGrL9/identity-isn-t-in-specific-atoms); humans growing up in the same cultural tradition can be seen as being drawn from a similar _distribution_ as my teenage self.)
From the perspective of axiomatic antisexism that I held at the time, this assertion is cringe-inducing. Of course most people are straight, but is it not all the _same love_?
-I wasn't ready to hear it then, but—I mean, probably not? So, for the _most_ part, all humans are extremely similar: [as Yudkowsky would soon write about](https://www.lesswrong.com/posts/Cyj6wQLW6SeF6aGLy/the-psychological-unity-of-humankind) [(following Leda Cosmides and John Tooby)](https://www.cep.ucsb.edu/papers/pfc92.pdf), complex functional adaptations have to be species-universal in order to not get scrambled during meiosis. As a toy example, if some organelle gets assembled from ten genes, those ten alleles _all_ have to be nearly universal in the population—if each only has a frequency of 0.9, then the probability of getting them all right would only be 0.9<sup>10</sup> ≈ 0.349. If allele H [epistatically](https://en.wikipedia.org/wiki/Epistasis) only confers a fitness advantage when allele G at some other locus is already present, then G has to already be well on its way to fixation in order for there to be appreciable selective pressure for H. Evolution, feeding on variation, uses it up. Complicated functionality that requires multiple genes working in concert can only accrete gradually as each individual piece reaches fixation in the entire population, resulting in an intricate species-universal _design_: just about everyone has 206 bones, a liver, a parietal cortex, _&c_.

-In this way (contrary to the uninformed suspicions of those still faithful to the blank slate), evolutionary psychology actually turns out to be impressively antiracist discipline: maybe individual humans can differ in small ways like personality, or ancestry-groups in small ways like skin color, but these are, and _have_ to be, "shallow" low-complexity variations on the same basic human design; new _complex_ functionality would require speciation.

This luck does not extend to antisexism. If the genome were a computer program, it would have `if female { /* ... */ } else if male { /* ... */ }` conditional blocks, and inside those blocks, you can have complex sex-specific functionality. By default, selection pressures on one sex tend to drag the other along for the ride—men have nipples because there's no particular reason for them not to—but in those cases where it was advantageous in the environment of evolutionary adaptedness for females and males to do things _differently_, sexual dimorphism can evolve (slowly—[more than one and half orders of magnitude slower than monomorphic adaptations](/papers/rogers-mukherjee-quantitative_genetics_of_sexual_dimorphism.pdf), in fact).
The evolutionary theorist Robert Trivers wrote, "One can, in effect, treat the sexes as if they were different species, the opposite sex being a resource relevant to producing maximum surviving offspring" (!!). There actually isn't one species-universal design—it's _two_ designs.
-If you're willing to admit to the possibility of psychological sex differences _at all_, you have to admit that sex differences in the parts of the mind that are _specifically about mating_ are going to be a prime candidate. (But by no means the only one—different means of reproductive have different implications for [life-history strategies](https://en.wikipedia.org/wiki/Life_history_theory) far beyond the act of mating itself.) Even if there's a lot of "shared code" in how love-and-attachment works in general, there are also going to be specific differences that were [optimized for](https://www.lesswrong.com/posts/8vpf46nLMDYPC6wA4/optimization-and-the-intelligence-explosion) facilitating males impregnating females. In that sense, the claim that "the love of a man for a woman, and the love of a woman for a man, have not been cognitively derived from each other" just seems commonsensically _true_.

I guess if you _didn't_ grow up with a quasi-religious fervor for psychological sex differences denialism, this whole theoretical line of argument about evolutionary psychology doesn't seem world-shatteringly impactful?—maybe it just looks like supplementary Science Details brushed over some basic facts of human existence that everyone knows. But if you _have_ built your identity around [quasi-religious _denial_](/2020/Apr/peering-through-reverent-fingers/) of certain basic facts of human existence that everyone knows (if not everyone [knows that they know](https://www.lesswrong.com/posts/CqyJzDZWvGhhFJ7dY/belief-in-belief)), getting forced out of it by sufficient weight of Science Details [can be a pretty rough experience](https://www.greaterwrong.com/posts/XM9SwdBGn8ATf8kq3/c/comment/Zv5mrMThBkkjDAqv9).

Sex differences would come up a couple more times in one of the last Sequences, on "Fun Theory"—speculations on how life could be truly _good_ if the world were superintelligently optimized for human values, in contrast to the cruelty and tragedy of our precarious existence [in a world shaped only by blind evolutionary forces](https://www.lesswrong.com/posts/sYgv4eYH82JEsTD34/beyond-the-reach-of-god).
Another post in this vein that had a huge impact on me was ["Changing Emotions"](https://www.lesswrong.com/posts/QZs4vkC7cbyjL9XA9/changing-emotions). As an illustration of how [the hope for radical human enhancement is fraught with](https://www.lesswrong.com/posts/EQkELCGiGQwvrrp3L/growing-up-is-hard) technical difficulties, Yudkowsky sketches a picture of just how difficult an actual male-to-female sex change would be.
-It would be hard to overstate how much of an impact this post had on me. I've previously linked it on this blog five different times. In June 2008, half a year before it was published, I encountered the [2004 mailing list post](http://lists.extropy.org/pipermail/extropy-chat/2004-September/008924.html) that was its predecessor. (The fact that I was trawling through old mailing list archives searching for Yudkowsky content that I hadn't already read, tells you something about what a fanboy I am.)

The argument goes: it might be easy to _imagine_ changing sex and refer to the idea in a short English sentence, but the real physical world has implementation details, and the implementation details aren't filled in by the short English sentence. The human body, including the brain, is an enormously complex integrated organism; there's no [plug-and-play](https://en.wikipedia.org/wiki/Plug_and_play) architecture by which you can just swap your brain into a new body and have everything Just Work without re-mapping the connections in your motor cortex. And even that's not _really_ a sex change, as far as the whole integrated system is concerned—
> Remapping the connections from the remapped somatic areas to the pleasure center will ... give you a vagina-shaped penis, more or less. That doesn't make you a woman. You'd still be attracted to girls, and no, that would not make you a lesbian; it would make you a normal, masculine man wearing a female body like a suit of clothing.

Not just form, but content—just like a male judo expert would need skills repatterned to become a female judo expert, so too, you know how to operate a male brain but not a female brain. You are the equivalent of a judo expert at one, but not the other. You have _cognitive_ reflexes, and consciously learned cognitive skills as well.

-> What happens when, as a woman, you think back to your memory of looking at Angelina Jolie photos as a man? How do you _empathize_ with your _past self_ of the opposite sex? Do you flee in horror from the person you were? Are all your life's memories distant and alien things? How can you _remember_, when your memory is a recorded activation pattern for neural circuits that no longer exist in their old forms? Do we rewrite all your memories, too?

But, well ... I mean, um ...
From the standpoint of my secret erotic fantasy, "normal, masculine man wearing a female body like a suit of clothing" is actually a _great_ outcome—the _ideal_ outcome. Let me explain.
-The main plot of my secret erotic fantasy accomodates many frame stories, but I tend to prefer those that invoke the [literary genre of science](https://www.lesswrong.com/posts/4Bwr6s9dofvqPWakn/science-as-attire), and posit "technology" rather than "spells" or "potions" as the agent of change, even if it's all ultimately magic (where ["magic" is a term of art for anything you don't understand how to implement as a computer program](https://www.lesswrong.com/posts/kpRSCH7ALLcb6ucWM/say-not-complexity)).

So imagine having something like [the transporter in _Star Trek_](https://memory-alpha.fandom.com/wiki/Transporter), but you re-materialize with the body of someone else, rather than your original body—a little booth I could walk in, dissolve in a tingly glowy special effect for a few seconds, and walk out looking like (say) [Nana Visitor (circa 1998)](https://memory-alpha.fandom.com/wiki/Kay_Eaton?file=Kay_Eaton.jpg). (In the folklore of [female-transformation erotica](/2016/Oct/exactly-what-it-says-on-the-tin/), this machine is often called the ["morphic adaptation unit"](https://www.cyoc.net/interactives/chapter_115321.html).)
-This high-level description of a hypothetical fantasy technology leaves some details unspecified—not just the _how_, but the _what_. What would the indistinguishable-from-magical transformation booth do to my brain? [As a preference-revealing thought experiment](https://www.lesswrong.com/posts/DdEKcS6JcW7ordZqQ/not-taking-over-the-world), what would I _want_ it to do, if I can't change [the basic nature of reality](https://www.lesswrong.com/posts/tPqQdLCuxanjhoaNs/reductionism), but if engineering practicalities weren't a constraint? (That is, I'm allowed to posit any atom-configuration without having to worry about how you would get all the atoms in the right place, but I'm not allowed to posit tethering my immortal soul to a new body, because [souls](https://www.lesswrong.com/posts/u6JzcFtPGiznFgDxP/excluding-the-supernatural) [aren't](https://www.lesswrong.com/posts/7Au7kvRAPREm3ADcK/psychic-powers) [real](https://www.lesswrong.com/posts/fdEWWr8St59bXLbQr/zombies-zombies).)

The anti-plug-and-play argument makes me confident that it would have to change _something_ about my mind in order to integrate it with a new female body—if nothing else, my unmodified brain doesn't physically _fit_ inside Nana Visitor's skull. ([One meta-analysis puts the sex difference in intracranial volume and brain volume at](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3969295/) a gaping [Cohen's _d_](/2019/Sep/does-general-intelligence-deflate-standardized-effect-sizes-of-cognitive-sex-differences/) ≈ 3.0 and 2.1, respectively, and Visitor doesn't look like she has an unusually large head.)
-Fine—we're assuming that difficulty away and stipulating that the magical transformation booth can make the _minimal_ changes necessary to put my brain in a female body, and have it fit, and have all the motor-connection/body-mapping stuff line up so that I can move and talk normally in a body that feels like mine.

I want this more than I can say. But is that _all_ I want? What about all the _other_ sex differences in the brain? Male brains are more lateralized—doing [relatively more communication within hemispheres rather than between](https://www.pnas.org/content/111/2/823); there are language tasks that women and men perform equally well on, but [men's brains use only the _left_ inferior frontal gyrus, whereas women's use both](/papers/shaywitz-et_al-sex_differences_in_the_functional_organization_of_the_brain_for_language.pdf). Women have a relatively thicker corpus callosum; men have a relatively larger amygdala. Fetal testosterone levels [increase the amount of gray matter in posterior lateral orbitofrontal cortex, but decrease the gray matter in Wernicke's area](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3306238/) ...
The hard part has to do with traits that are meaningfully sexually dimorphic, but not as a discrete dichotomy—where the sex-specific universal designs differ in ways that are _subtler_ than the presence or absence of entire reproductive organs. (Yes, I know about [homology](https://en.wikipedia.org/wiki/Homology_(biology))—and _you_ know what I meant.) We are _not_ satisfied if the magical transformation technology swaps out my penis and testicles for a functioning female reproductive system without changing the rest of my body, because we want the end result to be indistinguishable from having been drawn from the female distribution (at least, indistinguishable _modulo_ having my memories of life as a male before the magical transformation), and a man-who-somehow-magically-has-a-vagina doesn't qualify.
-The "obvious" way to to do the mapping is to keep the same percentile rank within each trait, but take it with respect to the target sex's distribution. I'm 5′11″ tall, which [puts me at](https://dqydj.com/height-percentile-calculator-for-men-and-women/) the 73rd percentile for American men, about 6/10ths of a standard deviation above the mean. So _presumably_ we want to say that my female analogue is at the 73rd percentile for American women, about 5′5½″.
+The "obvious" way to to do the mapping is to keep the same percentile rank within "each trait" (given some suitably exhaustive parsing of the human design into individual "traits"), but take it with respect to the target sex's distribution.

So _presumably_ we want to say that my female analogue is at the 73rd percentile for American women, about 5′5½″.
You might think this is "unfair": some women—about 7 per 1000—are 5′11″, and we don't want to say they're somehow _less female_ on that account, so why can't I keep my height? The problem is that if we refuse to adjust for every trait for which the female and male distributions overlap (on the grounds that _some_ women have the same trait value as my male self), we don't end up with a result from the female distribution.
-The typical point in a high-dimensional distribution is _not_ typical along each dimension individually. [In 100 flips of a biased coin](http://zackmdavis.net/blog/2019/05/the-typical-set/) that lands Heads 0.6 of the time, the _single_ most likely sequence is 100 Heads, but there's only one of those and you're _vanishingly_ unlikely to actually see it. The sequences you'll actually observe will have close to 60 Heads. Each such sequence is individually less probable than the all-Heads sequence, but there are vastly more of them. Similarly, [most of the probability-mass of a high-dimensional multivariate normal distribution is concentrated in a thin "shell" some distance away from the mode](https://www.johndcook.com/blog/2011/09/01/multivariate-normal-shell/), for the same reason. (The _same_ reason: the binomial distribution converges to the normal in the limit of large _n_.)

-Statistical sex differences are like flipping two different collections of coins with different biases, where the coins represent various traits. Learning the outcome of any individual flip, doesn't tell you which set the coin came from, but [if we look at the aggregation of many flips, we can get _godlike_ confidence](https://www.lesswrong.com/posts/cu7YY7WdgJBs3DpmJ/the-univariate-fallacy-1) as to which collection we're looking at.

A single-variable measurement like height is like a single coin: unless the coin is _very_ biased, one flip can't tell you much about the bias. But there are lots of things about people for which it's not that they can't be measured, but that the measurements require _more than one number_—which correspondingly offer more information about the distribution generating them.
-And knowledge about the distribution is genuinely informative. Occasionally you hear progressive-minded people dismiss and disdain simpleminded transphobes who believe that chromosomes determine sex, when actually, most people haven't been karyotyped and don't _know_ what chromosomes they have. Certainly, I agree that almost no one besides professional geneticists interact with sex chromosomes on a day-to-day basis; no one even knew that sex chromosomes _existed_ before 1905. [(Co-discovered by a woman!)](https://en.wikipedia.org/wiki/Nettie_Stevens) But the function of [intensional definitions](https://www.lesswrong.com/posts/HsznWM9A7NiuGsp28/extensions-and-intensions) in human natural language isn't to exhaustively [pinpoint](https://www.lesswrong.com/posts/3FoMuCLqZggTxoC3S/logical-pinpointing) a concept in the detail it would be implemented in an AI's executing code, but rather to provide a "treasure map" sufficient for a listener to pick out the corresponding concept in their own world-model: that's why [Diogenes exhibiting a plucked chicken in response to Plato's definition of a human as a "featherless biped"](https://www.lesswrong.com/posts/jMTbQj9XB5ah2maup/similarity-clusters) seems like a cheap "gotcha"—we all instantly know that's not what Plato meant. ["The challenge is figuring out which things are similar to each other—which things are clustered together—and sometimes, which things have a common cause."](https://www.lesswrong.com/posts/d5NyJ2Lf6N22AD9PB/where-to-draw-the-boundary)

-But sex chromosomes, and to a large extent specifically the SRY gene located on the Y chromosome, _is_ at the root of the [causal graph](https://www.lesswrong.com/posts/hzuSDMx7pd2uxFc5w/causal-diagrams-and-causal-models) underlying all other sex differences. A smart natural philosopher living _before_ 1905, knowing about all the various observed differences between women and men, might have guessed at the existence of some molecular mechanism of sex determination, and been _right_. By the "treasure map" standard, "XX is female; XY is male" is a pretty _well-performing_ definition—if you're looking for a [_simple_ membership test](https://www.lesswrong.com/posts/edEXi4SpkXfvaX42j/schelling-categories-and-simple-membership-tests)

Take faces. People are [verifiably very good at recognizing sex from (hair covered, males clean-shaven) photographs of people's faces](/papers/bruce_et_al-sex_discrimination_how_do_we_tell.pdf) (96% accuracy, which is the equivalent of _d_ ≈ 3.5), but we don't have direct introspective access into what _specific_ features our brains are using to do it; we just look, and _somehow_ know. The differences are real, but it's not a matter of any single, simple measurement you could perform with a ruler (like the distance between someone's eyes). Rather, it's a high-dimensional _pattern_ in many measurements you could take with a ruler, no one of which is definitive. [Covering up the nose makes people slower and slightly worse at sexing faces, but people don't do better than chance at guessing sex from photos of noses alone](/papers/roberts-bruce-feature_saliency_in_judging_the_sex_and_familiarity_of_faces.pdf).
Notably, for _images_ of faces, we actually _do_ have transformation technology! (Not "magical", because we know how it works.) AI techniques like [generative adversarial networks](https://arxiv.org/abs/1812.04948) and [autoencoders](https://towardsdatascience.com/generating-images-with-autoencoders-77fd3a8dd368) can learn the structure of the distribution of facial photographs, and use that knowledge to synthesize faces from scratch (as demonstrated by [_thispersondoesnotexist.com_](https://thispersondoesnotexist.com/))—or [do things like](https://arxiv.org/abs/1907.10786) sex transformation (as demonstrated by [FaceApp](https://www.faceapp.com/), the _uniquely best piece of software in the world_).
-If you let each pixel vary independently, the space of possible 1024x1024 images is 1,048,576-dimensional, but the vast hypermajority of those images aren't photorealistic human faces. Letting each pixel vary independently is the wrong way to think about it: changing the lighting or pose changes a lot of pixels in what humans would regard as images of "the same" face. So instead, our machine-learning algorithms learn a [compressed](https://www.lesswrong.com/posts/ex63DPisEjomutkCw/msg-len) representation of what makes the tiny subspace (relative to images-in-general) of _faces in particular_ similar to each other. That [latent space](https://towardsdatascience.com/understanding-latent-space-in-machine-learning-de5a7c687d8d) is a lot smaller (say, 512 dimensions), but still rich enough to embed the distinctions that humans notice: [you can find a hyperplane that separates](https://youtu.be/dCKbRCUyop8?t=1433) smiling from non-smiling faces, or glasses from no-glasses, or young from old, or different races—or female and male. Sliding along the [normal vector](https://en.wikipedia.org/wiki/Normal_(geometry)) to that [hyperplane](https://en.wikipedia.org/wiki/Hyperplane) gives the desired transformation: producing images that are "more female" (as the model has learned that concept) while keeping "everything else" the same.

Two-dimensional _images_ of people are _vastly_ simpler than the actual people themselves in the real physical universe. But _in theory_, a lot of the same _mathematical principles_ would apply to hypothetical future nanotechnology-wielding AI systems that could, like the AI in "Failed Utopia #4-2", synthesize a human being from scratch (this-person-_didn't_-exist-dot-com?), or do a real-world sex transformation (PersonApp?)—and the same statistical morals apply to reasoning about sex differences in psychology and (which is to say) the brain.
-Daphna Joel _et al._ [argue](https://www.pnas.org/content/112/50/15468) [that](https://www.pnas.org/content/112/50/15468) human brains are "unique 'mosaics' of features" that cannot be categorized into distinct _female_ and _male_ classes, because it's rare for brains to be "internally consistent"—female-typical or male-typical along _every_ dimension. It's true and important that brains aren't _discretely_ sexually dimorphic the way genitals are, but as [Marco del Guidice _et al._ point out](http://cogprints.org/10046/1/Delgiudice_etal_critique_joel_2015.pdf), the "cannot be categorized into two distinct classes" claim seems false in an important sense. The lack of "internal consistency" in Joel _et al._'s sense is exactly the behavior we expect from multivariate normal-ish distributions with different-but-not-vastly-different means. (There aren't going to be many traits where the sexes are like, _four_ or whatever standard deviations apart.) It's just like how sequences of flips of a very Heads-biased and very Tails-biased coin are going to be unique "mosaics" of Heads and Tails, but pretty distinguishable with enough flips—and indeed, with the right stats methodology, [MRI scans can predict sex at 96.8% accuracy](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6374327/).

-Sex differences in the brain are like sex differences in the skeleton: anthropologists can tell female and male skeletons apart (the [pelvis is shaped differently](https://johnhawks.net/explainer/laboratory/sexual-dimorphism-pelvis), for obvious reasons), and [machine-learning models can see very reliable differences that human radiologists can't](/papers/yune_et_al-beyond_human_perception_sexual_dimorphism_in_hand_and_wrist_radiographs.pdf), but neither sex has entire _bones_ that the other doesn't, and the same is true of brain regions.

-Maybe this should just look like supplementary Statistics Details brushed over some basic facts of human existence that everyone knows? I'm a pretty weird guy, in more ways than one. I am not prototypically masculine. Most men are not like me. If I'm allowed to cherry-pick what measurements to take, I can name ways in which my mosaic is more female-typical than male-typical. (For example, I'm _sure_ I'm above the female mean in [Big Five Neuroticism](https://en.wikipedia.org/wiki/Big_Five_personality_traits).) ["[A] weakly negative correlation can be mistaken for a strong positive one with a bit of selective memory."](https://www.lesswrong.com/posts/veN86cBhoe7mBxXLk/categorizing-has-consequences) But "weird" represents a much larger space of possibilities than "normal", much as [_nonapples_ are a less cohesive category than _apples_](https://www.lesswrong.com/posts/2mLZiWxWKZyaRgcn7/selling-nonapples). If you _sum over_ all of my traits, everything that makes me, _me_—it's going to be a point in the _male_ region of the existing, unremediated, genderspace.

-Okay, maybe I'm _not_ completely over my teenage religion of psychological sex differences denialism?—that belief still feels uncomfortable to put my weight on. I want to believe that there are women who are relevantly "like me" with respect to some fair (not gerrymandered) metric on personspace. But, um ... it's not completely obvious whether I actually know any? When I look around me—most of the people in my robot cult (and much more so if you look the core of old-timers from the _Overcoming Bias_ days, rather than the greater Berkeley "community" of today) are male.

+Okay, maybe I'm _not_ completely over my teenage religion of psychological sex differences denialism?—that belief still feels uncomfortable to put my weight on.

I was once told by a very smart friend (who, unlike me, is not a religious fantatic), "Boys like games with challenges and points; girls like games with characters and stories."

-_Alright_. So _in principle_, you could imagine having a PersonApp that maps that point to the female region of configuration space in some appropriately structure-preserving way, to compute my female analogue who is as authentically _me_ as possible while also being authentically female, down to her pelvis shape, and the proportion of gray matter in her posterior lateral orbitofrontal cortex, and—the love of a woman for a man. What is she like, concretely? Do I know how to imagine that?

Or if I can imagine it, can I _describe_ it in this blog post?

I have mental models of people, and the models get queried for predictions in the course of planning my social behavior, but I don't have introspective access to the differences between models. It's easier to imagine people in hypothetical situations and say things like, "That doesn't sound like something she'd _do_, but _he_ would" (and be correct), than to say exactly it is about her character and his that generated these predictions (such that [my words would paint a picture in your head](https://www.lesswrong.com/posts/YF9HB6cWCJrDK5pBM/words-as-mental-paintbrush-handles) that would let you make your own predictions about her and him without having met them)—just like how you're better at recognizing someone's face, than at describing their face in words in enough detail for an artist to draw a portrait.

But in a lot of ways that matter, we are _very_ different people. When you compare representative outputs of what we've _done_ with our (roughly) similar intelligence—her chemistry Ph.D. from a top-10 university, my _batshit insane_ secret ("secret") blog about the philosophy of science and the etiology of late-onset gender dysphoria in males—it ... paints a different picture.
Of course same-sex siblings would _also_ be different pictures. (Identical twins aren't _duplicates_ of each other, either.) But the advantage of having a sister is that it gives my brain's pattern-matching faculties a target to [sight](https://en.wikipedia.org/wiki/Sight_(device)) against. As a _second_-order approximation, my female analogue is close to being somewhere on the vector in personspace between me and my sister (but not exactly on that line, because the line spans both the difference-betwen-siblings and the difference-between-sexes).

Okay. Having supplied just enough language to _start_ to talk about what it would even mean to actually become female—is that what I _want_? I mean, if it's reversible, I would definitely be extremely eager to _try_ it ...
What if I can't just "try" it? What if the machine can only be used once? Or (my preference) if some deep "brain sex" transformation only works once, even if a more superficial motor remapping is easy to do or re-do? Come up with whatever frame story you want for this: maybe the machine costs my life savings just to rent for two minutes, or maybe the transformation process is ever-so-slightly imperfect, such that you can't re-transform someone who's already been transformed once, like a photocopy being a perfectly acceptable substitute for an original document, but photocopies-of-photocopies rapidly losing quality.
-In that case, if I have to choose ... I _don't_ think I want to be Actually Female? I _like_ who I am on the inside, and don't need to change it. I don't _want_ to stop liking challenges and points as much as I do—and if I don't know enough neuroscience to have an _informed_ preference about the ratio of gray to white matter in my posterior lateral orbitofrontal cortex, I'm sure it's _probably fine_.

-This is probably counterintuitive if you haven't been living with it your entire adult life?

+If the magical transformation technology were real, I would want a full-length mirror. (And in the real world, I would probably crossdress a _lot_ more often, if I could pass to myself in the mirror. My face ruins it and makeup doesn't help.)
What's going on here? _Speaking_ of mirrors, the sexologist [James Cantor speculates](https://youtu.be/q3Ub65CwiRI?t=281): mirror neurons. Way, way back in the 1980s, Italian neuroscientists wired up the brains of macaque monkeys with electrodes, and noticed that some of the _same_ brain regions would light up when the monkey grabbed a rasin, and when the monkey watched the _researcher_ eat a rasin. These "mirror neurons" are speculated to form the basis of empathy.
So, the _phrase_ "mirror neurons" is not and _cannot_ be an answer. Real understanding is about detailed predictive models, not [what words to repeat back in school](https://www.lesswrong.com/posts/NMoLJuDJEms7Ku9XS/guessing-the-teacher-s-password). I can't expect to understand the real answer without spending multiple years studying neuroscience, and if I did, I couldn't expect to transmit the model to you in one blog post. (That would be _several_ blog posts.)
-Still, the macaque–rasin anecdote is at least _suggestive_ of hypotheses in the _general area_ of, "The brain uses _shared_ representations for 'self' and others, in a way such that it's possible for the part of the brain that computes sexual attraction to 'get confused' about the self–other distinction in a way that manifests as sexual desire to _be_ the object of attraction."

Or _something like that_.
+
+One interesting prediction of this story is that if the nature of the "confusion" is agnostic to the _target_ of sexual attraction, then you should see the same pattern in men with unusual sexual interests.

So if some men are attracted to, say, amputees, we would expect some fraction of _them_ to [get off on the idea of _being_ amputees](/papers/lawrence-clinical_and_theoretical_paralells.pdf)—[_apotemnophilia_](https://en.wikipedia.org/wiki/Body_integrity_dysphoria#History).

I don't _know_ the details of what this "erotic target location error" thing is supposed to _be_, exactly—and would expect my beliefs to change a lot if _anyone_ knew the details and could explain them to me—but I think _some story in this general vicinity_ has to be the real explanation of what's going on with me. How _else_ do you make sense of an otherwise apparently normal biological male (whose physical and psychological traits seem to be basically in the male normal range, even if he's one of those sensitive bookish males rather than being "macho") having the _conjunction_ of the beautiful pure sacred self-identity thing _and_, specifically, erotic female-transformation fantasies of the kind I've described?
But I _don't_ think she/he would spontaneously invent obsessively jacking off to fantasies of being able to magically transform into various _different_ female bodies ... unless she was _already_ into that stuff before being magically transformed into my twin. But ... is that even a thing among many (or any) lesbians? To be clear, there is a _lot_ of porn in this genre! But it seems to mostly be created for and consumed by ... men? Adult human males?

We can imagine that a male who was _like_ me in having this erotic-target-location-erroneous sexuality and associated beautiful pure sacred self-identity feelings, but who [read different books in a different order](/2020/Nov/the-feeling-is-mutual/), might come to very different conclusions about himself.

> If I fell asleep and woke up as a true woman—not in body, but in brain—I don't think I'd call her "me". The change is too sharp, if it happens all at once.
The rules don't change when the entity X happens to be "my female analogue" and the category Y happens to be "me". The ordinary concept of "personal identity" tracks how the high-level features of individual human organisms are stable over time. You're going to want to model me-on-Monday and me-on-Thursday as "the same" person even if my Thursday-self woke up on the wrong side of bed and has three whole days of new memories. When interacting with my Thursday-self, you're going to be using your existing mental model of me, plus a diff for "He's grumpy" and "Haven't seen him in three days"—but that's a _very small_ diff, compared to the diff between me and some other specific person you know, or the diff between me and a generic human who you don't know.
-In everyday life, we're almost never in doubt as to which entities we want to consider "the same" person (like me-on-Monday and me-on-Thursday), but we can concoct science-fictional thought experiments that force [the Sorites problem](https://plato.stanford.edu/entries/sorites-paradox/) to come up.

But if a twenty-year-old were to be magically replaced with their sixty-year-old future self (not just superficially wearing an older body like a suit of clothing, but their brain actually encoding forty more years of experience and decay) ... well, there's a reason I reached for the word "replace" (suggesting putting a _different_ thing in something's place) when describing the scenario.

But if a twenty-year-old were to be magically replaced with their sixty-year-old future self (not just superficially wearing an older body like a suit of clothing, but their brain actually encoding forty more years of experience and decay) ... well, there's a reason I reached for the word "replace" (suggesting putting a _different_ thing in something's place) when describing the scenario. That's what Yudkowsky means by "the change is too sharp"—the _ordinary_ sense in which we model people as the "same person" from day to day (despite people having [more than one proton](/2019/Dec/on-the-argumentative-form-super-proton-things-tend-to-come-in-varieties/) in a different place from day to day) has an implicit [Lipschitz condition](https://en.wikipedia.org/wiki/Lipschitz_continuity) buried in it, as assumption that people don't change _too fast_.
The thing about Sorites problems is that they're _incredibly boring_. The map is not the territory. The distribution of sand-configurations we face in everyday life is such that we usually have an answer as to whether the sand "is a heap" or "is not a heap", but in the edge-cases where we're not sure, arguing about whether to use the word "heap" _doesn't change the configuration of sand_. You might think that if [the category is blurry](https://www.lesswrong.com/posts/dLJv2CoRCgeC2mPgj/the-fallacy-of-gray), you therefore have some freedom to [draw its boundaries](https://www.lesswrong.com/posts/d5NyJ2Lf6N22AD9PB/where-to-draw-the-boundary) the way you prefer—but [the cognitive function of the category is for making probabilistic inferences on the basis of category-membership](https://www.lesswrong.com/posts/esRZaPXSHgWzyB2NL/where-to-draw-the-boundaries), and those probabilistic inferences can be quantitatively better or worse. Preferences over concept definitions that aren't about maximizing predictive accuracy are therefore preferences _for deception_, because "making probability distributions less accurate in order to achieve some other goal" is exactly what _deception_ means.
Same principle when Yudkowsky wrote, "If I fell asleep and woke up as a true woman [...] I don't think I'd call her 'me'". The claim is that psychological sex differences are large enough to violate the Lipschitz condition imposed by our _ordinary_ concept of personal identity. Maybe he was wrong, but if so, that cashes out as being wrong _about_ how similar women and men actually are (which in principle could be operationalized and precisely computed, even if _we_ don't know how to make it precise), _not_ whether we prefer the "call her me" or "don't call her me" conclusion and want to _retroactively redefine the meaning of the words in order to make the claim come out "true."_

+Do people ever really recover from being religious? I still endorse the underlying psychological motivation that makes me prefer the "call her me" conclusion, the _intention_ that made me think I could get away with defining it to be true. Now that I don't believe that anymore—now that I can't take for granted that actual women aren't a somewhat unfathomable Other onto me—my world hasn't collapsed in the way religious people [tend to fear](https://www.lesswrong.com/posts/3XgYbghWruBMrPTAL/leave-a-line-of-retreat) when their most precious belief is threatened. It just means I have to do [a little more intellectual work](https://arbital.greaterwrong.com/p/rescue_utility) to figure out what's actually right.

_Why would I?_ In the English of my youth, "gender" (as a single word, rather than part of the phrase "gender role") was understood as a euphemism for _sex_ for people who were squeamish about the potential ambiguity betweeen _sex_-as-in-biological-sex and _sex_-as-in-intercourse. (Judging by this blog's domain name, I am not immune to this.) In that language, my "gender"—my sex—is male. Not because I'm necessarily happy about it (and I [used to](/2017/Jan/the-erotic-target-location-gift/) be pointedly insistent that I wasn't), but as an observable biological fact that, whatever my pure beautiful sacred self-identity feelings, _I am not delusional about_.
-Okay, so trans people aren't delusional about their [developmental sex](/2019/Sep/terminology-proposal-developmental-sex/); the claim is that their internal sense of their own gender is more real or more relevant in some sense and should take precedence.

-So where does that leave me? This post is about my _own_ experiences, and not anyone else's (which I obviously don't have access to). I've _mentioned_ transgenderedness several times in the main body of this post, but I've tried to mostly limit the intent of it to references to an explanation that one might be tempted to apply to my case, but which I don't think fits, or the brief summary of the two-type Blanchard taxonomy for which the word _autogynephilia_ (the obvious and perfect word for my thing) was coined. Everything I've said so far is _consistent_ with a world in which Blanchard was dumb and wrong, a world where my idiosyncratic weird sex perversion and associated beautiful pure sacred self-identity feelings are taxonomically and etiologically distinct from whatever brain-intersex condition causes _actual_ trans women. That's the world I _thought_ I lived in for the ten years after encountering the obvious and perfect word.

My first clue that I wasn't living in that world came from—Eliezer Yudkowsky. In [a 26 March 2016 Facebook post](https://www.facebook.com/yudkowsky/posts/10154078468809228), he wrote—
> If that starts to scale up, we might see a really, really interesting moral panic in 5-10 years or so. I mean, if you thought gay marriage was causing a moral panic, you just wait and see what comes next ...
-Indeed—here we are just 4¾ years later, and _I am panicking_. (As 2007–9 Sequences-era Yudkowsky [taught me](https://web.archive.org/web/20200225212407/https://www.yudkowsky.net/other/fiction/the-sword-of-good), and 2016 Facebook-shitposting-era Yudkowsky seemed to ignore, the thing that makes a moral panic really interesting is how hard it is to know you're on the right side of it—and how to [panic sideways in policyspace](https://www.overcomingbias.com/2007/05/policy_tugowar.html) when the "maximize the number of trans people" and "minimize the number of trans people" coalitions are both wrong.)

+At the time, this was merely _very confusing_ to hear coming from the guy who wrote "Changing Emotions". I left a careful comment in the Facebook thread (with the obligatory "speaking only for myself; I obviously know that I can't say anything about anyone else's experience" [disclaimer](https://www.overcomingbias.com/2008/06/against-disclai.html)), quietly puzzled at what Yudkowsky could possibly be thinking ...

+A month later, I moved out of my mom's house in Walnut Creek to live on the correct side of the [Caldecott tunnel](https://en.wikipedia.org/wiki/Caldecott_Tunnel), in Berkeley: closer to other people in the robot-cult scene and with a shorter train ride to my coding dayjob in San Francisco.
-[TODO: my reaction—from the comments and to "Whilhelm"]
-[TODO: Caldecott tunnel joke]
+(I would later change my mind about which side of the tunnel is the correct one.)
-But after moving to Berkeley and doing a little bit more reading ... I _don't_ think Blanchard was dumb and wrong. I think the two-type taxonomy is _basically_ correct, as a first approximation. (Where psychology is complicated enough such that there's much more to be said about what that means, and what better approximations would look like, but simple theories that [explain a lot of our observations](https://surveyanon.wordpress.com/2019/04/27/predictions-made-by-blanchards-typology/) are better than pretending not to have a theory.) I think a _substantial majority_ of trans women under modern conditions in Western countries are, essentially, guys like me who were _less self-aware about what the thing actually is_.

So, I realize this is an inflamatory and (far more importantly) _surprising_ claim. Obviously, I don't have introspective access into other people's minds. If someone claims to have an internal sense of her own gender that doesn't match her assigned sex at birth, on what evidence could I _possibly_ have the _astounding_ arrogance to reply, "No, actually I think you're just a perverted male like me"?
