This is a post written by David Thorstad, a philosophy professor who maintains a blog for criticizing various tenets of effective altruism called Reflective Altruism, as part of a series of on human biodiversity (HBD), a modern iteration of so-called race science. HBD, of course, isn't typical fare for EA, or any of its championed causes. Yet it has, to much controversy over the years, been recognized as a subject of interest among prominent thinkers associated with either the effective altruism or rationality communities, or others writers they've been affiliated with. This latest post in Thorstad's series provides a critical overview of @Scott Alexander's history of engagement with said body of ideas, both on his current blog, Astral Codex Ten (ACX), as well as before then, such as on his previous blog, Slate Star Codex (SSC).
I identify with your asterisk quite a bit. I used to be much more strongly involved in rationalist circles in 2018-2020, including the infamous Culture War Thread. I distanced myself from it around ~2020, at the time of the NYT controversy, mostly just remaining on Rationalist Tumblr. (I kinda got out at the right time because after I left everyone moved to Substack, which positioned itself against the NYT by personally inviting Scott, and was seemingly designed to encourage every reactionary tendency of the community.)
One of the most salient memories of the alt-right infestation in the SSC fandom to me was this comment by a regular SSC commenter with an overtly antisemitic username, bluntly stating the alt-right strategy for recruiting ~rationalists:
There is isn't really much more to say, he essentially spilled the beans – but in front on an audience who pride itself so much in "high-decoupling" that they can't warp their mind around the idea that overt neo-Nazis might in fact be bad people who abuse social norms of discussion to their advantage – even when said neo-Nazis are openly bragging about it to their face.
If one is a a rationalist who seek to raise the sanity waterline and widely spread the tools of sound epistemology, and even more so if one is an effective altruist who seek to expand the moral circle of humanity, then there is zero benefit to encourage discussion of the currently unknowable etiology of a correlation between two scientifically dubious categories, when the overwhelming majority of people writing about it don't actually care about it, and only seek to use it as a gateway to rehabilitating a pseudoscientific concept universally rejected by biologists and geneticists, on explicitly epistemologically subjectivist and irrationalist grounds, to advance a discriminatory-to-genocidal political project.
