-Because, I did, actually, trust him. Back in 2009 when _Less Wrong_ was new, we had a thread of hyperbolic ["Eliezer Yudkowsky Facts"](https://www.lesswrong.com/posts/Ndtb22KYBxpBsagpj/eliezer-yudkowsky-facts) (in the style of [Chuck Norris facts](https://en.wikipedia.org/wiki/Chuck_Norris_facts)).

+Perhaps he thinks it's unreasonable for someone to hold him to higher standards. As he [wrote](https://twitter.com/ESYudkowsky/status/1356493883094441984) [on](https://twitter.com/ESYudkowsky/status/1356494097511370752) [Twitter](https://twitter.com/ESYudkowsky/status/1356494399945854976) in February 2021:

+> It's strange and disingenuous to pretend that the master truthseekers of any age of history, must all have been blurting out everything they knew in public, at all times, on pain of not possibly being able to retain their Art otherwise. I doubt Richard Feynman was like that. More likely is that, say, he tried to avoid telling outright lies or making public confusions worse, but mainly got by on having a much-sharper-than-average dividing line in his mine between peer pressure against saying something, and that thing being _false_.
+
+I've read _Surely You're Joking, Mr. Feynman_. I cannot imagine Richard Feynman trying to get away with the "sometimes personally prudent and not community-harmful" line. (On the other hand, I couldn't have imagined Yudkowsky doing so in 2009.)
+
+Other science educators in the current year such as [Richard Dawkins](https://www.theguardian.com/books/2021/apr/20/richard-dawkins-loses-humanist-of-the-year-trans-comments), University of Chicago professor [Jerry Coyne](https://whyevolutionistrue.com/2023/08/27/on-helen-joyces-trans/), or ex-Harvard professor [Carole Hooven](https://www.thefp.com/p/carole-hooven-why-i-left-harvard) have been willing to pay political costs to stand up for the scientific truth that biological sex continues to be real even when it hurts people's feelings.
+
+If Yudkowsky thinks he's too important for that (because his popularity with progressives has much greater impact on the history of Earth-originating intelligent life than Carole Hooven's), that might be the right act-consequentialist decision, but one of the consequences he should be tracking is that he's forfeiting the trust of everyone who expected him to live up to the epistemic standards successfully upheld by UChicago or Harvard biology professors.
+
+It looks foolish in retrospect, but I did trust him much more than that.
