+But then, in a March 2016 Facebook post, Yudkowsky [proclaimed that](https://www.facebook.com/yudkowsky/posts/10154078468809228) "for people roughly similar to the Bay Area / European mix, I think I'm over 50% probability at this point that at least 20% of the ones with penises are actually women."
+
+This seemed like a huge and surprising reversal from the position articulated in "Changing Emotions"! The two posts weren't _necessarily_ inconsistent, _if_ you assumed gender identity is an objectively real property synonymous with "brain sex", and that "Changing Emotions"'s harsh (almost mocking) skepticism of the idea of true male-to-female sex change was directed at the sex-change fantasies of _cis_ men (with a male gender-identity/brain-sex), whereas the 2016 Facebook post was about _trans women_ (with a female gender-identity/brain-sex), which are a different thing.
+
+But this potential unification seemed very dubious to me, especially if "actual" trans women were purported to be "at least 20% of the ones with penises" (!!) in some population. _After it's been pointed out_, it should be a pretty obvious hypothesis that "guy on the Extropians mailing list in 2004 who fantasizes about having a female but 'otherwise identical' copy of himself" and "guy in 2016 Berkeley who identifies as a trans woman" are the _same guy_.
