-(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_.
+In one taxon, the "early-onset" type, you have same-sex-attracted males who have just been extremely feminine (in social behavior, interests, _&c._) their entire lives, in a way that causes huge social problems for them—the far tail of feminine gay men who end up fitting into the world better as straight women. _That's_ where the "woman trapped inside a man's body" trope comes from. This one probably is a brain-intersex condition. [TODO: cite that from Brown's bibliography]
+
+That story is pretty intuitive. Were an alien AI to be informed of the fact that, among humans, some fraction of males elect to undergo medical interventions to resememble females, and aspire to be perceived as females socially, "brain-intersex condition such that they already behave like females" would probably be its top hypothesis for the cause of such behavior, just on priors.
+
+Suppose our alien AI were to be informed that many of the human males seeking to become female (as far as the technology can manage, anyway) do _not_ fit this profile. If you [didn't have enough data to _prove_ anything, but you had to guess](https://www.lesswrong.com/posts/xTyuQ3cgsPjifr7oj/faster-than-science), what would be your _second_ guess for how this behavior might arise?
+
+What's the _usual_ reason for males to be obsessed with female bodies?
+
+So, yeah. Basically, 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_.
