Trigger warning: racism.
I personally found this letter incredibly difficult to read. Beyond the content of the email, the apology is also terribly written, and reads like Nick, an intellectual leader in EA and longtermism, might still hold these views today to some degree. It also reads like Nick is primarily just trying to do damage control for using a racial slur, or preemptive PR work for some other reason, as opposed to focusing on the harms he may be contributing to, and the folks he is apologizing to. In this context, this also sounds like a dog-whistle:
Are there any genetic contributors to differences between groups in cognitive abilities? It is not my area of expertise, and I don’t have any particular interest in the question. I would leave to others, who have more relevant knowledge, to debate whether or not in addition to environmental factors, epigenetic or genetic factors play any role.
Myself and other EAs I know are worried about professional reputational risks of continued association with the EA movement or longtermism. This is not just a PR risk, and despite my view that this reflects terribly on Nick and any comms experts who may have been involved in this, I don't want this to imply that the PR angle is what we should be primarily concerned about here-it isn't! But whether or not one of the leaders of EA has held racist views for decades, and whether he still basically holds them today is important.
It has real implications for the movement's future, including selection effects on people who may become more uncertain about the views that intellectual leaders of the EA/longtermism movement hold (and by extension, its intellectual foundations), whether EA is a community for "people like them", and whether EA is a movement that is well-equipped to preserve a future for all of humanity. Even if they aren't uncertain, they may be more reluctant to take risks to continue or become more outwardly involved in an increasingly controversial social movement. This may also affect the view of current and prospective donors to EA causes.
These are not concerns held solely by "EA outsiders" or those who are already unsympathetic to EA.
Reactions on Twitter-read on at your own peril!
(The EA forum seems to default to strong-upvotes on your own posts. I don't know why this is, but I'll probably change mine to a normal upvote if this post gets some engagement.)
To add one more person's impression, I agree with ofer that he apology was "reasonable," I disagree with him that your post "reads as if it was optimized to cause as much drama as possible, rather than for pro-social goals," and I agree with Amber Dawn that the original email is somewhat worse than something I'd have expected most people to have in their past. (That doesn't necessarily mean it deserves any punishment decades later and with the apology –non-neurotyptical people can definitely make a lot of progress between, say, early twenties and later in life, in understanding how their words affect others and how edginess isn't the same as being sophisticated.)
I think this is one of these "struggles of norms" where you can't have more than one sacred principle, and ofer's and my position is something like "it should be okay to say 'I don't know what's true' on a topic where the truth seems unclear ((but not, e.g., something like Holocaust denial))." Because a community that doesn't prioritize truth-seeking will run into massive troubles, so even if there's a sense in which kindness is ultimately more important than truth-seeking (I definitely think so!), it just doesn't make sense as an instrumental norm to treat it as sacred (so that one essentially forces people to say things that might be false or else they are punished).
Separately from that, I think it's bad to reinforce the idea that group averages have any normative relevance whatsoever. If we speak as though the defence against racism is empirically finding that all intelligence differences for group averages are at most environmentally-caused, then that's a weak defence against racism! It's "weak" because it could turn out to be false. But in reality, I don't think there's any possible finding that could make us think "racism is okay." In my view, not being racist – in the sense that has moral significance for me – means that (1) you're not more inclined to falsely reach a conclusion about people from a different ethnicity than you'd reach the same conclusion about (e.g.) your own ethnicity and (2) when you consider "candidates" (in whatever context) with equal characteristics/interests/qualifications, etc., you're not more inclined to treat some worse than others based solely on their ethnicity. If we hold this view, we get to relax to about what could be found out about group averages.
That said, I do agree that there's very little, if anything, to gain from discussions about group averages, and that the people who are eager to bring up the topic seem morally suspicious. (In this specific case of Bostrom_2023 writing the apology, it's not like he could have chosen to avoid the topic entirely – so given the mistakes he made 26 years ago, he had to address it again.)
