There's a thing I've sometimes noticed happening in social science debates. In the spirit of How to Write Quickly While Maintaining Epistemic Rigor, let's consider an example.

A note: I'm going to pick a controversial example, of the causes of transsexuality. This is because for the past few years, I have been studying transsexuality to try to understand its causes better, and so it's an example I have thought deeply about and know a lot about. And because I've been hit by the problem described in this post.

But understandably, it's also something that a lot of people, particularly trans people and people involved in pro- or anti-trans politics, care a lot about. Given the centrality of the example, I think its reasonable to debate object-level matters of the example in the comments, but everyone on all sides should be careful about mindkilling.

Blanchard's autogynephilia theory

Why do trans women transition? As in, what is it that causes them to be transgender, rather than to live happily as men? While there is disagreement about this question, insofar as the trans community gives you an answer, it tends to be something like:

Your brain expects to have a certain kind of body, either male or female, and it expects to live in a specific gender role, either as a man or as a woman. Some people are born with brains of the opposite sex. This causes distress, and can be fixed by transitioning to live as the sex that matches their brain. And thus you get trans people.

This narrative has a great degree of flaws and inconsistencies, which I won't belabor here (though if you can't see any, feel free to ask in the comments, and I will reply). It's probably not surprising that the narrative is so flawed; it's not selected for truth, but instead for political convenience, because it allows an easy way to describe what it is like to be trans, and because the policies people tend to derive from it favor trans people.

But given the inaccuracy, we might wish for another, more accurate narrative. There are a million other idiosyncratic theories than this one, but there's probably one narrative that stands above all of the others in terms of scientific support, quality of derivation, and so on. It has many names, but I will call it the Blanchardian model, named after Ray Blanchard, a major figure in its development:

There are two different kinds of trans women, homosexual (exclusively attracted to men) and autogynephilic (have a sexual interest in being women). The homosexual ones are the ones who are closest to the classical transgender narrative, in that they tend to be very feminine, and this is likely a factor in why they transition. The other kind, autogynephilic transsexuals, are the most common kind. They have a sexual interest in being women, which may present in various ways, such as sexual fantasies about having a female body, transvestic fetishism, etc.. They are attracted to women, because autogynephilia is a sort of "inversion" or "miswiring" of their pre-existing attraction to women.

Autogynephilia itself can be quite broad. I think the instance people are most familiar with is transvestic fetishism, but according to a survey I did, the most common forms might involve sex as a woman (with either a man or a woman), or masturbation as a woman. A classical example of autogynephilia in internet porn is transgender transformations, erotic material depicting men who turn into women, but surprisingly I didn't hear much of that in my survey. (It should be noted that most autogynephiles don't transition, but instead live as non-transgender men.)

There's a huge ton of details, qualifications, etc., that can be added to this model; at times the model makes claims that seem unreasonable, but once you start learning the evidence for the claims, some of the unreasonable-looking claims start seeming more like hidden insights than like reasons to disbelieve. For brevity, though, I won’t go into the details in this post.

Critics are really bad

At this point, I've spent years studying the causes of transsexuality. At first, I was critical of the Blanchardian theory for various reasons. But I gradually learned things that made it seem more and more plausible. And one thing that struck me just as much as the raw evidence that was presented, was the quality of the arguments presented. Often, the researchers critical of Blanchardianism had plainly obvious rationalizations, misrepresented theory and evidence, and made extremely questionable inferences.

To give a fairly typical example, there is the Identity-Defense Model of Gender Variant Development, which claims that autogynephilia develops as a result of taboos around males who want to be female. This being in an attempt to downplay the correlation between autogynephilia and transsexuality by proposing that it is due to reverse causation.

But it relies strongly on the notion that taboo things become erotic, and while this is a popular idea, I've yet to see any convincing evidence for it, nor have the various people I've seen advocate for the theory been able to provide much. (Feel free to debate this in the comments.) It doesn't seem to make any sort of evolutionary sense, and it doesn't seem to me to check out in terms of commonsense correlations (the most popular erotic acts seem to be the least taboo, while highly taboo erotic acts like incest seem highly unpopular - and this doesn't seem to me to be reverse causality).

To give another example of bad critics, here is a quote from probably the most popular critique of autogynephilia, Julia Serano's Case Against Autogynephilia:

To put this sexualization in perspective, consider the following analogy: Many natal women have sexual fantasies about being raped (reviewed in Leitenberg & Henning, 1995). It is one thing to respectfully attempt to explore and understand such rape fantasies. It would be an entirely different thing to insist that there are two subtypes of women—those who have rape fantasies and those who do not; to use the label “autoraptophiles” when describing women who have such fantasies and to insist that they are primarily motivated by their desire to be raped; to include “autoraptophilia” as a modifier in the Diagnostic and Statistical Manual of Mental Disorders; and to encourage the lay public to actively distinguish between those women who are “autoraptophiles” and those who are not. Such actions would undoubtedly have a severe, negative impact on women (who are already routinely sexualized and marginalized in our culture).

While one can definitely discuss the political controversy that the concept of autogynephilia stirs up, Julia Serano's analogy doesn't seem to hold at all. The damage done by the "autoraptophilia" concept would presumably be in suggesting that women want to be raped, and so contributing to the likelihood of women getting raped. Which is bad because women very much want to avoid getting raped. Meanwhile, the analogous implication for trans women would be suggesting that they want to... be female? But that is hardly harmful for trans women, nor is it a unique implication of Blanchardianism.

If anything, Serano's own conception of autogynephilia, as indicative of a desire to be a woman, rather than being one component that adds up with other component to influence preferences, seems on a deeper mechanistic level closer to the theory that "autoraptophilic" women want to be raped.

Blanchardians are bad

So, due to a combination of empirical evidence for Blanchardianism (which I have not reviewed in this post), and the bad critics (mentioned previously), I ended up buying into the theory and using it as a basis for my research. After all, if the evidence supports it, and nobody can critique it well, surely it must be right. And I ended up becoming pretty notorious for it, being basically the resident Blanchardian in various rationalist-adjacent groups for years.

However, while there were quite a few insights I accumulated from Blanchardianism, there were also quite a few places where I found it to be stretching the truth more and more. One major case of this is the concept of erotic target location errors:

The way Blanchardians make sense of autogynephilia is as an inverted attraction to women. That is, under ordinary circumstances, males find women to be sexually attractive as partners. However, in a subset of males, ?some glitch? happens, and this makes them find it erotic to be women, where the things they would otherwise find erotic when done to women, become things they would find erotic to be done to themselves as women.

One major prediction of this model is that autogynephiles can't be gay. And for what seems to be complicated historical reasons that don't make sense, Blanchardians also insist that autogynephiles can't be bisexual. Instead, apparent homosexuality among autogynephiles is explained away with various theories, a major one being what is known as "pseudo-bisexuality/pseudo-androphilia" or "meta-attraction".

Meta-attraction is a phenomenon where autogynephiles have a secondary sexual interest in men, not due to attraction to men in the classical sense, but instead as a side-effect of their autogynephilia, limited to only exist with themselves as women. For instance in surveys I've seen a lot of straight men who fantasize about being women and having sex with men. The consensus theory from Blanchardians is that things like this explains all autogynephiles' sexual interest in men, and that none are attracted to men in the classical sense.

I bought into this and advocated for it for a while, partly because Blanchardianism had earned my trust, and partly because there seemed to be some evidence for it. However, my belief became more and more strained over time, as I gradually accumulated evidence that contradicted its predictions. This eventually culminated in a blog post, Meta-attraction cannot account for all autogynephiles' interest in men, arguing that the consensus was contradicted by the balance of evidence so far.

This led to... not much. While there was acknowledgement that my post presented nontrivial evidence (email response by Michael Bailey), it has still been continued to be taken as an axiom that autogynephiles cannot be attracted to men, without any good reason.

The poor response to this lead me to reevaluating my trust in the Blanchardian researchers, and reexamining a variety of issues I had bought into. It turns out that there's actually a lot of really questionable ideas that are just taken for granted by them! Sometimes they reach the level where I'd call them dishonest! This has led me to accidentally gradually build up a series of posts that call "my debunking of Blanchardianism" (in a "ha ha only serious" way).


Here's what I see as the dynamics in this and other situations:

You've got a group of politically motivated people, who advocate strongly for one narrative. This narrative is really bad, because it's not optimized for truth, it's optimized for political convenience.

But as a result, people find the original narrative unworkable, so they come up with their own counternarrative, which is somewhat more reality-based, but really not all that better; it ends up overly rigid and narrow, because it's main function is to cover the cases that don't fit well under the original narrative.

The people who are politically biased criticize the counternarrative. However, because they only really care about the political aspects of it, they don't focus on the parts where the counternarrative is weakest, and often don't even fully understand the counternarrative; instead they just focus on the aspects they find most politically objectionable.

The end result is that the counternarrative looks like it is well-supported by evidence, and has stood up to any critique you could throw at it. But really it's full of myths and it starts to break once you push it a bit on an axis orthogonal to the political controversy.

Often, the counternarrative may still have a nugget of truth, or a good point about some things. I would still absolutely apply ideas from Blanchardianism to analyzing transsexuality. But this sort of thing can demote the counternarrative from being the central part of the story to just being an obnoxiously polarizing piece of the puzzle.

One early response I got, by someone who preferred to be anonymous, had some objections to this part:

But it relies strongly on the notion that taboo things become erotic, and while this is a popular idea, I've yet to see any convincing evidence for it, nor have the various people I've seen advocate for the theory been able to provide much.

The response was:

I agree the argument you're criticizing doesn't strike me as all that strong, but "taboos are sexy (to a non-negligible number of people, sometimes)" doesn't seem as unreasonable as you're painting it to me. As far as evidence goes: racialized porn searches are more common in deep south states with (presumably) more overt racism, incest porn is definitely a thing with a market, etc. The thing you may be missing is that taboo stuff is often sexy for people to think about, but taboos are taboo for a reason and so they are often a bad idea to actually do, so people mostly don't.

Autogynephilia mostly happens, in the blanchardian model, in the autogynephile's head, so it'd be more like watching incest porn than actually trying to sleep with a genetically related family member.

As I understand it, the deep south also has a higher prevalence of black people, which seems to me to be a much better explanation of the search prevalence than taboos.

When it comes to incest porn, I think there are several layers to this. One is actually that it can be counterintuitively hard to estimate the prevalence of something without systematic studies; this almost seems like it deserves its own post, but for now I will address it in this comment. I think the main way people guess the amount of interest in incest porn is via things like how often it appears in highly rated videos on porn sites, or how high it ranks among search terms.

But incest is taboo, so presumably incest porn production is lower than what would be implied by the demand. As a result, presumably the demand that does exist gets concentrated on fewer videos. (This depends on the relative degree that incest taboos reduce porn production vs porn consumption.) But this means that those fewer videos would, on average, get more views; which would make them more likely to appear high in the porn rankings.

To test this theory, I made a script to scrape PornHub videos for metadata, and then I looked at whether the prevalence of incest themes depended on the view distribution. The results, badly graphed, are here. Basically, the above idea turned out to be right; if you consider the most popular videos, you overestimate the popularity of incest porn.

I think some similar things might happen with search terms. A search term can be highly popular, while still making up only a small fraction of the search volume.

Also, the theory I'm criticizing isn't "taboos are sexy to a non-negligible number of people, sometimes". In order for taboos to consistently cause autogynephilia in the way Veale describes, it has to be "taboos are sexy to most people". Otherwise, it would only predict that a "non-negligible number" of trans women are autogynephilic.

(I guess an alternative could be to argue that trans women are particularly likely to find taboos sexy, and so even if most people don't, most trans women would. I don't think this is an argument that Veale would forward, but of course the entire point of this post is that one can't necessarily rely on critics to forward those arguments....)

Also, I think it's worth distinguishing between "finding something that happens to be taboo sexy" and "finding things sexy because they are taboo". Simply observing that some people are into incest is not that strong of an argument; if it's because of the taboo, one would expect them to also find other taboo things erotic.

There is indeed some evidence that a subset of people finds taboos sexy (I call it the taboo/disgust factor of sexuality; a variety of sexual interests, including incest, pedophilia, coprophilia, zoophilia, murdersex, etc., all appear to be correlated, at least in self-reports - though this could also be accounted for taboos being unsexy to most but not all people - further research is needed).

I got a response from another person preferring to be anonymous, who brought up to points:

  • That trans women tend to feel that autogynephilia does not explain much of their feelings;
  • Whether Blanchardianism can properly account for asexual trans women.

Here's my responses to each of the points:

When it comes to whether autogynephilia explains most of trans women's gender feelings, I think there are several aspects to this that I eventually want to write about. I can only go briefly into them here, but:

  • Most autogynephiles don't transition, don't develop serious gender dysphoria, etc.., so clearly there must be something distinguishing those who do from those who don't. So actually yes, it's not the only thing going on (though I think it is one of the biggest ones, but that's another discussion). Some Blanchardians try to focus on hypothesizing moderators which influence the effect of autogynephilia on gender issues, but I see no reason that the distinguishing factors couldn't just be different causes entirely unrelated to autogynephilia.
  • I think the methods people use for causal inference on their individual life don't necessarily become relevant on the population level. For instance, if you see some sort of problem with being a man, but most cis men also see the same problem, then it may be a cause of gender dysphoria in the sense of being something that explains why one would rather want to be a woman than be a man, but it's not a cause of your gender dysphoria in the sense of being something that explains why you, compared to other AMABs, would rather want to be a woman than be a man.

When it comes to asexual trans women, a lot of people seem to think asexual trans women are very hard to account for and need strange contortions when applying Blanchardianism. But it's fairly consistently found that asexual trans women self-report similar levels of autogynephilia (usually measured by transvestic fetishism, having ever experienced sexual arousal while wearing women's clothes) to gynephilic trans women. See this post for details. I think this is actually one of the strengths of Blanchardianism; there's this highly counterintuitive phenomenon which Blanchardianism acknowledges and attempts to explain, and which is so counterintuitive that critics tend to just dismiss Blanchardianism because it acknowledges it.
