-But perhaps I'm not appreciating exactly what stringent constraints he's operating under? The filtered-evidence disclaimer comment mentions "speakable and unspeakable arguments", and judges that the speakable argument in the original post was "good _on net_ to publish" (emphasis mine). Maybe Yudkowsky doesn't see himself as being obligated to publically consider downsides of the "simplest and best protocol" proposed in the post, if he considers the _main_ thesis of the post to have simply been the "speakable" pronouns-shouldn't-denote-sex argument.
+But perhaps it's premature to judge Yudkowsky without appreciating what tight constraints he labors under. The disclaimer comment mentions "speakable and unspeakable arguments"—but what, exactly, is the boundary of the "speakable"? In response to a commenter mentioning the cost of having to remember pronouns as a potential counterargument, Yudkowsky [offers us another clue](https://www.facebook.com/yudkowsky/posts/10159421750419228?comment_id=10159421833274228&reply_comment_id=10159421871809228):

+> People might be able to speak that. A clearer example of a forbidden counterargument would be something like e.g. imagine if there was a pair of experimental studies somehow proving that (a) everybody claiming to experience gender dysphoria was lying, and that (b) they then got more favorable treatment from the rest of society. We wouldn't be able to talk about that. No such study exists to the best of my own knowledge, and in this case we might well hear about it from the other side to whom this is the exact opposite of unspeakable; but that would be an example.

+Well, I think (a) and (b) _as stated_ are clearly false, so "we" (who?) fortunately aren't losing much by allegedly not being able to speak them. But what about some _similar_ hypotheses, that might be similarly unspeakable for similar reasons? Consider the claims that (a') self-reports about gender dysphoria are substantially distorted by [socially-desirable responding tendencies](https://en.wikipedia.org/wiki/Social-desirability_bias)—as a notable example, heterosexual males with sexual fantasies about being female often falsely deny or minimize the erotic dimension of their desire to change sex; and that (b') transitioning is socially rewarded within particular _subcultures_, although not Society as a whole.
