Title: Sexual Dimorphism in Yudkowsky's Sequences, in Relation to My Gender Problems Date: 2021-01-01 Category: commentary Tags: autogynephilia, bullet-biting, Eliezer Yudkowsky, epistemic horror, my robot cult, personal, sex differences Status: draft > _I'll write my way out > Write everything down, far as I can see > I'll write my way out > Overwhelm them with honesty > This is the eye of the hurricane > This is the only way I can protect my legacy_ > > —"Hurricane", _Hamilton_ So, as I sometimes allude to, I've spent basically my entire adult life in this insular intellectual subculture that was founded in the late 'aughts to promulgate an ideal of _systematically correct reasoning_—general methods of thought that result in true beliefs and successful plans—and, [incidentally](https://www.lesswrong.com/posts/4PPE6D635iBcGPGRy/rationality-common-interest-of-many-causes), to use these methods of systematically correct reasoning to prevent superintelligent machines from [destroying all value in the universe](https://www.lesswrong.com/posts/GNnHHmm8EzePmKzPk/value-is-fragile). Lately I've been calling it my "robot cult" (a phrase [due to Dale Carrico](https://amormundi.blogspot.com/2011/08/ten-reasons-to-take-seriously.html))—the pejorative is partially [ironically affectionate](https://www.lesswrong.com/posts/gBma88LH3CLQsqyfS/cultish-countercultishness), and partially an expression of betrayal-trauma acquired from that time almost everyone I [used to trust](https://www.lesswrong.com/posts/wustx45CPL5rZenuo/no-safe-defense-not-even-science) insisted on, on ... Well. That's a _long story_—for another time, perhaps. For _now_, I want to explain how my robot cult's foundational texts had an enormous influence on my self-concept in relation to sex and gender. It all started in summer 2007 (I was nineteen years old), when I came across _Overcoming Bias_, a blog on the theme of how to achieve more accurate beliefs. (I don't remember exactly how I was referred, but I think it was likely to have been [a link from Megan McArdle](https://web.archive.org/web/20071129181942/http://www.janegalt.net/archives/009783.html), then writing as "Jane Galt" at _Asymmetrical Information_.) [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. The first thing—the chronologically first thing. Ever since I was thirteen or fourteen years old— (and I _really_ didn't expect to be blogging about this eighteen years later) (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. Or check out my few, circumspect contributions to [the popular genre of](/2016/Oct/exactly-what-it-says-on-the-tin/) captioned-photo female transformation erotica: [1](/ancillary/captions/dr-equality-and-the-great-shift/) [2](/ancillary/captions/the-other-side-of-me/) [3](/ancillary/captions/the-impossible-box/) [4](/ancillary/captions/de-gustibus-non-est/).) 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).) But within a couple years, I also developed this beautiful pure sacred self-identity thing, where I was also having a lot of _non_-sexual thoughts about being a girl. Just—little day-to-day thoughts. Like when I would write in my pocket notebook in the persona of my female analogue. Or when I would practice swirling the descenders on all the lowercase letters that had descenders [(_g_, _j_, _p_, _y_, _z_)](/images/handwritten_phrase_jazzy_puppy.jpg) because I thought it made my handwriting look more feminine. Or the time when track and field practice split up into boys and girls, and I ironically muttered under my breath, "Why did I even join this team?—boys, I mean." [TODO: notebook photos] [TODO: more examples! Initials!] And so on. The beautiful pure sacred self-identity thing doesn't _feel_ explicitly erotic. The thing I did in the day in class about writing in my notebook about being a girl, was _very different_ from the thing I did in my room at night about _visualizing_ girls with this abstract sense of "But what if that were _me_?" while furiously masturbating. The former activity was my beautiful pure happy romantic daydream, whereas the latter activity was not beautiful or pure at all! Now I am not a cognitive scientist, and can't claim to _know_ exactly what my beautiful pure sacred self-identity thing is, or where it comes from—that's [not the kind of thing I would expect people to _know_ from introspection alone](/2016/Sep/psychology-is-about-invalidating-peoples-identities/). But it has always seemed like a pretty obvious guess that there must have been _some sort of causal relationship_ between the erotic thing, and the beautiful pure sacred self-identity thing, even if the two things don't _feel_ the same: the overlap in subject matter is too much to be a coincidence. And the erotic thing definitely came _first_. Maybe this story reads differently in 2020 from how it was to live in 2005? I think that teenage boys in the current year having the kind of feelings I was having then, upon referencing or hinting at the beautiful pure sacred self-identity thing— (and the beautiful pure sacred self-identity thing is _much_ easier to talk about than the erotic thing) (I mean, the beautiful pure sacred self-identity thing is much harder to talk about _clearly_, but talking about it _un_-clearly is less shameful and requires much less bravery) —are immediately provided with "Oh, that means you're not a cis boy; you're a trans girl" as the definitive explanation. But it was a different time, then. Of course I had _heard of_ transsexualism as a thing, in the form of the "woman trapped in a man's body" trope, but it wasn't something I expected to actually encounter in real life. 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_. [TODO: need to introduce the word "autogynephilia" and link to "Beacon Through the Darkness", probably around here] This brings me to the other thing I need to explain about my teenage years, which is that I became 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_. So, you know, 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—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. (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.) That overwhelming feeling of cold horror and hatred at _the enemy revealed_—that, I conjecture, is what religious people feel when encountering a heretical text for the first time. (In _principle_, a sufficiently advanced neuroscience would be able to confirm that it is the same emotion, as a matter of biological fact.) The social–psychological need to [avoid the belief's real weak points](https://www.lesswrong.com/posts/dHQkDNMhj692ayx78/avoiding-your-belief-s-real-weak-points) is why the "religion" characterization makes sense, even if the claim that psychological sex differences are fake isn't a [_supernatural_](https://www.lesswrong.com/posts/u6JzcFtPGiznFgDxP/excluding-the-supernatural) one. But quasi-religious ideological fervor aside, there was presumably a _reason_ I cared so much about being a good pro-feminist _specifically_, and hardly spent any time at all thinking about other dimensions of social justice, like race or class. And I think the reason is because, because ... Well. The reason I'm blogging this story at all is because I'm scared that in order to finish that sentence in the current year and be understood, I'd have to say, "because I was trans." And with respect to what the words mean in the current year, it's true. But that's not how I think of it, then or now. It's because I was _straight_. Because I loved women, and wanted to do right by them. It's an _identificatory_ kind of love, inseparable from my sense of self—but if it isn't _exactly_ the same thing that most straight men feel, it can only be a slight variation. ------ Anyway, that's some background about where I was at, personally and ideologically, _before_ I fell in with this robot cult. My ideological committment to psychological-sex-differences denialism made me uncomfortable when the topic of sex differences happened to come up on the blog—which wasn't particularly often at all, but in such a _vast_ body of work as the Sequences, it did happen to come up a few times (and those few times are the subject of this blog post). For example, as part of [an early explanation of why the values we would want to program into an artificial superintelligence don't reduce to any one simple principle](https://www.lesswrong.com/posts/NnohDYHNnKDtbiMyp/fake-utility-functions), Yudkowsky remarks 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 or from any other value." 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 0.910 ≈ 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). [TODO: bridge paragraphs ... this denial was in the background in "The Opposite Sex" and the metaethics sequence, men should think of themselves as men] 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). [TODO: rewrite/expand description here—"Sympathetic Minds" first, then bridge to "Failed Utopia #4-2"] The short story ["Failed Utopia #4-2"](https://www.lesswrong.com/posts/ctpkTaqTKbmm6uRgC/failed-utopia-4-2) portrays an almost-aligned superintelligence constructing a happiness-maximizing utopia for humans—except that because [evolution didn't design women and men to be optimal partners for each other](https://www.lesswrong.com/posts/Py3uGnncqXuEfPtQp/interpersonal-entanglement), and the AI is prohibited from editing people's minds, the happiness-maximizing solution ends up splitting up the human species by sex and giving women and men their own _separate_ utopias, complete with artificially-synthesized romantic partners. At the time, [I expressed horror](https://www.greaterwrong.com/posts/ctpkTaqTKbmm6uRgC/failed-utopia-4-2/comment/PhiGnX7qKzzgn2aKb) at the idea in the comments section, because my quasi-religious psychological-sex-differences denialism required that I be horrified. But looking back eleven years later, the _argument makes sense_ (though you need an additional [handwave](https://tvtropes.org/pmwiki/pmwiki.php/Main/HandWave) to explain why the AI doesn't give every _individual_ their separate utopia—if existing women and men aren't optimal partners for each other, so too are individual men not optimal same-sex friends for each other). On my reading of the text, it is _significant_ that the AI-synthesized complements for men are given their own name, the _verthandi_ (presumably after [the Norse deity](https://en.wikipedia.org/wiki/Ver%C3%B0andi)), rather than just being referred to as women. The _verthandi_ may _look like_ women, they may be _approximately_ psychologically human, but the _detailed_ psychology of "superintelligently-engineered optimal romantic partner for a human male" is not going to come out of the distribution of actual human females, and judicious exercise of the [tenth virtue of precision](http://yudkowsky.net/rational/virtues/) demands that a _different word_ be coined for this hypothetical science-fictional type of person. Calling the _verthandi_ "women" would be _worse writing_; it would _fail to communicate_ the impact of what has taken place in the story. 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. [TODO: re-count and fix old-LW links to "Changing Emotions"] It would be hard to overstate how much of an impact this post had on me. I've previously linked it on this blog eight 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.) I immediately wrote to a friend: "[...] I cannot adequately talk about my feelings. Am I shocked, liberated, relieved, scared, angry, amused?" 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— [TODO: include more blockquote here] > 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. But, well ... I mean, um ... (I still really don't want to be blogging about this, but _somebody has to and no one else will_) 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 indistinguishable from magic rather than magic _simpliciter_. So imagine having something like the transporter in _Star Trek_, 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/) ... Do I want the magical transformation technology to fix all that, too? Do I have _any idea_ what it would even _mean_ to fix all that, without spending multiple lifetimes studying neuroscience? I think I have just enough language to _start_ to talk about what it would mean. [TODO: rewrite this whole section to be more focused on _just_ explaining the math language needed to explain how the transformation mapping would work, using face and height as "easy" examples] 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 measurement: [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). [TODO: Mathematically, Joel et al. and response—maybe in next paragraph Beyond the Binary: https://www.pnas.org/content/112/50/15468 http://cogprints.org/10046/1/Delgiudice_etal_critique_joel_2015.pdf http://zackmdavis.net/blog/2019/05/the-typical-set/ > once you draw a boundary around a group, the mind starts trying to harvest similarities from the group.

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 I'm 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).) 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. In principle, you could define a procedure 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 the proportion of gray matter in her posterior lateral orbitofrontal cortex and—the love of a woman for a man. (Note that we can already basically do this for _images_ of female and male faces, using the [latent spaces found by generative adversarial networks](https://arxiv.org/abs/1907.10786) and [autoencoders](https://towardsdatascience.com/generating-images-with-autoencoders-77fd3a8dd368), as demonstrated by the likes of [FaceApp](https://www.faceapp.com/), the _uniquely best piece of software in the world_. Doing it for _actual whole people in the real world_ and not just flat images is a task for future superintelligences, not present-day GANs, but some of same basic principles should apply.) [TODO: mention https://thispersondoesnotexist.com/ ; we can synthesize images from scratch] Okay. Having supplied just enough language to _start_ to talk about what it would mean to actually become female—is that what I _want_? I mean, I would definitely be extremely eager to _try_ it ... I had said we're assuming away engineering difficulties in order to make the thought experiment more informative about pure preferences, but let's add back one constraint to _force_ the thought experiment to be informative about preferences, and not allow the wishy-washy evasion of "I'm eager to _try_ it." What if I can't just "try" it? What if the machine can only be used once? 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. So, I guess ... if I'm being honest ... I guess I _want_ to be a normal man wearing a female body like a suit of clothing. Is that weird? Is that wrong? Okay, yes, it's _obviously_ weird and wrong, but should I care more about not being weird and wrong, than I do about my deepest most heartfelt desire that I've thought about every day for the last eighteen years? This is probably counterintuitive if you haven't been living with it your entire adult life? People have _heard of_ the "born in the wrong body" narrative, which makes intuitive sense: if female souls are designed to work female bodies, and you have a female soul tethered to a male body, you can imagine the soul finding the mismatch distressing and wanting to fix it. But if, as I'm positing for my case, there _is no mismatch_ in any objective sense, then where does the desire come from? How do you make sense of wanting to change physiological sex, for reasons that _don't_ have anything to do with already neurologically resembling that sex? What's really going on there, psychologically? Part of what makes this so hard to talk about _besides_ it being weird and wrong, is that we don't really understand how our own minds work in a legible way; we just experience things. Even if you're [not sure that other people really see "the same" colors as you](https://www.lesswrong.com/posts/3wYjyQ839MDsZ6E3L/seeing-red-dissolving-mary-s-room-and-qualia) (and you don't know how to [reformulate the question](https://www.lesswrong.com/posts/rQEwySCcLtdKHkrHp/righting-a-wrong-question) [to not](https://www.lesswrong.com/posts/Mc6QcrsbH5NRXbCRX/dissolving-the-question) [be confused](https://www.lesswrong.com/posts/XzrqkhfwtiSDgKoAF/wrong-questions)), you can at least agree on color _words_ by pointing to [Pantone swatches](https://en.wikipedia.org/wiki/Pantone#Pantone_Color_Matching_System), but I'm not sure I have the language to convey the facts about the qualia I associate with the word _autogynephilia_ to someone who doesn't already feel something similar. But I have to try. A clue: when I'm ... uh. When I'm—well, you know ... (I guess I can't evade responsibility for the fact that I am, in fact, blogging about this. This is the eye of the hurricane; this is the only way I can [protect](http://unremediatedgender.space/2019/Jul/the-source-of-our-power/)—) A clue: when I'm masturbating, and imagining all the forms I would take if the magical transformation technology were real (the frame story can vary, but the basic idea is always the same), I don't think I'm very _good_ at first-person visualization? The _content_ of the fantasy is about _me_ being a woman (I mean, having a woman's body), but the associated mental imagery mostly isn't the first-person perspective I would actually experience if the fantasy were real; I'm mostly imagining a specific woman (which one, varies a lot) from the outside, admiring her face, and her voice, and her breasts, but wanting the soul behind those eyes to be _me_. Wanting _my_ body to be shaped like _that_, to be in control of that avatar of beauty, and just to live like that. If the magical transformation technology were real, I would want a mirror. (And in the real world, I would probably crossdress a _lot_ more often, if I could pass to myself in the mirror.) What's going on here? The sexologist James Cantor [speculates](https://youtu.be/q3Ub65CwiRI?t=281): mirror neurons. https://www.lesswrong.com/posts/NMoLJuDJEms7Ku9XS/guessing-the-teacher-s-password [in particular, being Actually Female would undermine my _reason_ for wanting a female body] [if I could get HRT without the psych effects, that would actually be an improvement] [the fact that I'm happy with my breasts is suggestive of body-mods still being positive, even if the desire is a confusion] (The scintillating but ultimately untrue thought.) [but if you haven't made all these fine mental distinctions, you might think that you want to "be a woman", or at least be attached to the idea even if you don't believe it] [...] > 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. In the comments, [I wrote](https://www.greaterwrong.com/posts/QZs4vkC7cbyjL9XA9/changing-emotions/comment/4pttT7gQYLpfqCsNd)— > Is it cheating if you deliberately define your personal identity such that the answer is _No_? To which I now realize the correct answer is—_yes!_ Yes, it's cheating! Category-membership claims of the form "X is a Y" [represent hidden probabilistic inferences](https://www.lesswrong.com/posts/3nxs2WYDGzJbzcLMp/words-as-hidden-inferences); inferring that entity X is a member of category Y means [using observations about X to decide to use knowledge about members of Y to make predictions about features of X that you haven't observed yet](https://www.lesswrong.com/posts/gDWvLicHhcMfGmwaK/conditional-independence-and-naive-bayes). But this AI trick can only _work_ if the entities you've assigned to category Y are _actually_ similar—if they form a tight cluster in configuration space, such that using the center of the cluster to make predictions about unobserved features gets you _close_ to the right answer, on average. 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, but we can concoct science-fictional thought experiments that force [the Sorites problem](https://plato.stanford.edu/entries/sorites-paradox/) to come up. What if you could "merge" two people—construct a human with a personality "in between" yours and mine, that had both of our memories? (You know, like [Tuvix](https://memory-alpha.fandom.com/wiki/Tuvix_(episode)).) Would that person be me, or you, or both, or neither? (Derek Parfit has [a book](https://en.wikipedia.org/wiki/Reasons_and_Persons#Personal_identity) with lots of these.) [TODO: change scenario to interpolate between people, _at what point_ does it become] 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 preferences _for deception_. That's why defining your personal identity to get the answer you want is cheating. If the answer you wanted was actually _true_, you could just say so without needing to _want_ it. When [Phineas Gage's](/2017/Dec/interlude-xi/) friends [said he was "no longer Gage"](https://en.wikipedia.org/wiki/Phineas_Gage) after the railroad accident, what they were trying to say was that interacting with post-accident Gage was _more relevantly similar_ to interacting with a stranger than it was to interacting with pre-accident Gage, even if Gage-the-physical-organism was contiguous along the whole strech of space time. 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'"—maybe he was wrong, but if so, that cashes out as being wrong _about_ the some precise statement about the actual properties of similarity metrics on persons (which could be computed in principle, even if _we_ don't know how); I can't change the actual structure of minds in the world by defining my _identity_ differently. ------- Anyway, that—briefly (I mean it)—is the story about my weird obligate sex fantasy about being a woman and how I used to think that it was morally wrong to believe in psychological sex differences, but then I changed my mind and decided that psychological sex differences are probably real after being deeply influenced by this robot-cult blog about the logic of Science. It's probably not that interesting? If we were still living in the socio-political environment of 2009, I'm pretty sure I wouldn't be blogging about my weird sexual obsessions (as evidenced by the fact that, in 2009, I wasn't blogging about them). Imagine my surprise to discover that, in the current year, my weird sexual obsessions are at the center I'm weird, but I'm not _that_ weird. Men who fantasize about being women do not particularly resemble actual women! We just—don't? This seems kind of obvious, really? Telling the difference between fantasy and reality is kind of an important life skill?
