I got interested in effective altruism back before it was called effective altruism, back before Giving What We Can had a website. Later on, I got involved in my university EA group and helped run it for a few years. I joined the Effective Altruism Forum to try to figure out where effective altruism could fit into my life these days and what it means to me. You can read my latest thoughts on effective altruism here.
I write on Substack, and used to write on Medium.
Pronouns: she/her or they/them.
The context for what I'm discussing is explained in two Reflective Altruism posts: part 1 here and part 2 here.
Warning: This is a polemic that uses harsh language. I still completely, sincerely mean everything I say here and I consciously endorse it.[1]
It has never stopped shocking and disgusting me that the EA Forum is a place where someone can write a post arguing that Black Africans need Western-funded programs to edit their genomes to increase their intelligence in order to overcome global poverty and can cite overtly racist and white supremacist sources to support this argument (even a source with significant connections to the 1930s and 1940s Nazi Party in Germany and the American Nazi Party, a neo-Nazi party) and that post can receive a significant amount of approval and defense from people in EA, even after the thin disguise over top of the racism is removed by perceptive readers. That is such a bonkers thing and such a morally repugnant thing, I keep struggling to find words to express my exasperation and disbelief. Effective altruism as a movement probably deserves to fail for that, if it can't correct it.[2]
My loose, general impression is that people who got involved in EA because of global poverty and animal welfare tend to be broadly liberal or centre-left and tend to be at least sympathetic toward arguments about social justice and anti-racism. Conversely, my impression of LessWrong and the online/Bay Area rationalist community is that they don't like social justice, anti-racism, or socially/culturally progressive views. One of the most bewildering things I ever read on LessWrong was one of the site admins (an employee of Lightcone Infrastructure) arguing that closeted gay people probably tend to have low moral integrity because being closeted is a form of deception. I mean, what?! This is the "rationalist" community?? What are you talking about?! As I recall based on votes, a majority of forum users who voted on the comment agreed.[3]
Overall, LessWrong users seem broadly sympathetic to racist arguments and views.[4] Same for sexist or anti-feminist views, and extremely so for anti-LGBT (especially anti-trans) views. Personally, I find it to be the most unpleasant website I've spent more than ten hours reading. When I think of LessWrong, I picture a dark, dingy corner of a house. I truly find it to be awful.
The more I've thought about it, the more truth I find in the blogger Ozy Brennan's interpretation of the LessWrong and the rationalist community through the concept of the "cultic milieu" and a comparison to new religious movements (not cults in the more usual sense connoting high-control groups). Ozy Brennan self-identifies as a rationalist and is active in the community, which makes this analysis far more believable than if it came from an outsider. The way I'd interpret Ozy's blog post, which Ozy may not agree with, is that rationalists are in some sense fundamentally devoted to being incorrect, since they're fundamentally devoted to being against consensus or majority views on many major topics — regardless of whether those views are correct or incorrect — and inevitably that will lead to having a lot of incorrect views.
I see very loose, very limited analogies between LessWrong and online communities devoted discussing conspiracy theories like QAnon or to online incel communities. Conspiracy theories because LessWrong has a suspicious, distrustful, at least somewhat paranoid or hypervigilant view on people and the world, this impulse to turn over rocks to find where the bad stuff is. Also, there's the impulse to connect too much. To subsume too much under one theory or worldview. And too much reliance on one's own fringe community to explain the world and interpret everything. Both, in a sense, are communities built around esoteric knowledge. And, indeed, I've seen some typical sort of conspiracy theory-seeming stuff on LessWrong related to American intelligence agencies and so on.
Incel communities because the atmosphere of LessWrong feels rather bitter, resentful, angry, unhappy, isolated, desperate, arrogant, and hateful, and in its own way is also a sort of self-help or commiseration community for young men who feel left out of the normal social world. But rather than encouraging healthy, adaptive responses to that experience, instead both communities encourage anti-social behaviour, leaning into distorted thinking, resentment, and disdainful views of other people.
I just noticed that Ozy recently published a much longer article in Asterisk Magazine on the topic of actual high-control groups or high-demand groups with some connection to the rationalist community. It will take me a while to properly read the whole thing and to think about it. But at a glance, there are some aspects of the article that are relevant to what I'm discussing here, such as this quote:
And this quote:
And this one:
In principle, you could have the view that the typical or median person is benefitted by the Sequences or by LessWrong or the rationalist community, and it's just an unfortunate but uncommon side-effect for people to slip into cults or high-control groups. It sounds like that's what Ozy believes. My view is much harsher: by and large, the influence that LessWrong/the rationalist community has on people is bad, and people who take these ideas and this subculture to an extreme are just experiencing a more extreme version of the bad that happens to pretty much everyone who is influenced by these ideas and this subculture. (There might be truly minor exceptions to this, but I still see this as the overall trend.)
Obviously, there is now a lot of overlap between the EA Forum and LessWrong and between EA and the rationalist community. I think to the extent that LessWrong and the rationalist community have influenced EA, EA has become something much worse. It's become something repelling to me. I don't want any of this cult stuff. I don't want any of this racist stuff. Or conspiracy theory stuff. Or harmful self-help stuff for isolated young men. I'm happy to agree with the consensus view most of the time because I care about being correct much more than I care about being counter-consensus. I am extremely skeptical toward esoteric knowledge and I think it's virtually always either nonsense or prosaic stuff repackaged to look esoteric. I don't buy these promises of unlocking powerful secrets through obscure websites.
There was always a little bit of overlap between EA and the rationalist community, starting very early on, but it wasn't a ruinous amount. And it's not like EA didn't independently have its own problems before the rationalist community's influence increased a lot, but those problems seemed more manageable. The situation now feels like the rationalist community is unloading more and more of its cargo onto the boat that is EA, and EA is just sinking deeper and deeper into the water over time. I feel sour and queasy about this because EA was once something I loved and it's becoming increasingly laden with things I oppose in the strongest possible terms, like racism, interpersonal cruelty, and extremely irrational thinking patterns. How can people who were in EA because of global poverty and animal welfare, who had no previous affiliation with the rationalist community, stand this? Are they all gone already? Have they opted to recede from public arguments and just focus on their own particular niches? What gives?
And to the extent that the racism in EA is independently EA's problem and has nothing to do with the influence of the rationalist community (which obviously has to be more than nothing), then that is 100% EA's problem, but I can't imagine racism in EA could be satisfactorily addressed without significant conflict with and alienation of many people who overlap between the rationalist community and EA and who either endorse or strongly sympathize with racist views. (For example, in January 2023, when the Centre for Effective Altruism published a brief statement that affirmed the equality of Black people in response to the publication of a racist email by the philosopher Nick Bostrom, the most upvoted comment was from a prominent rationalist that started, "I feel really quite bad about this post," and argued at length that universal human equality is not a tenet of effective altruism. This is unbelievably foolish and unbelievably morally wrong. Independently, that person has said and done things that seem to indicate either support or sympathy for racist views, which makes me think it was probably not just a big misunderstanding.)[5] That's why the diversion from talking about racism on the EA Forum into discussing the rationalist community's influence on EA.
Racism is paradigmatically evil and there is no moral or rational justification for it. Don't lose sight of something so fundamental and clear. Don't let EA drown under the racism and all the other bad stuff people want to bring to it. (Hey, now EA is the drowning child! Talk about irony!)
Incidentally, LessWrong and the rationalist community are dead wrong about near-term AGI as well — specifically, the probability of AGI before January 1, 2033 is significantly less than 0.1% and the MIRI worldview on alignment is most likely either just generally wrong/misguided or at least not applicable to deep learning-based systems — and that poses its own big problem for EA to the extent that EA has been influenced to accept LessWrong/rationalists' views about near-term AGI. So, the influence of the rationalist community on EA has been damaging in multiple respects. (Although, again, EA bears responsibility for its part in all of it, both allowing the influence and for whatever portion of the mistake it would have made without that influence.)
About a day after posting this quick take, I changed the first sentence of this quick take from just italicized to a heading to make the links to the Reflective Altruism post more prominent and harder to miss. The sentence was always there.
Edited on October 25, 2025 at 11:22 PM Eastern to add: If you don't know about the incident I'm referring to here, the context for what I'm discussing is explained in two Reflective Altruism posts: part 1 here and part 2 here. The links to these Reflective Altruism posts were always in the first sentence of this quick take, but I'm adding this footnote to make those links harder to miss.
Edited on October 25, 2025 at 10:52 PM Eastern to add: I purposely omitted a link to this comment because I didn't want to make this quick take a confrontation against the person who wrote it. But if you don't believe me and you want to see the comment for yourself, send me a private message and I'll send you the link.
Edited on October 25, 2025 at 11:25 PM Eastern to add: This is extensively documented in a different Reflective Altruism post from the two I have already linked, which you can find here.
Edited on October 25, 2025 at 11:19 PM Eastern to add: I'm referring here to the Manifest 2024 conference, which was held at Lighthaven in Berkely, California, a venue owned by Lightcone Infrastructure, the same organization that owns and operates LessWrong. I'm also referring to the discussions that happened after the event. There have been many posts about this event on the EA Forum. One post I found interesting was from a pseudonymous self-described member of the rationalist community that was critical of some aspects of the event and of some aspects of the rationalist community. You can read that post here.
Edited on October 26, 2025 at 11:57 PM Eastern to add: See also the philosopher David Thorstad's post about Manifest 2024 on his blog Reflective Altruism. David's posts are nearly encyclopedic in their thoroughness and have an incredibly high information density.
If the EA community endorses or even just tolerates the decision and allows Manifund, Austin, and Caroline to participate in the community, e.g., through events hosted by EA orgs like the CEA (which as far as I know has not yet been ruled out), then in that sense Manifund, Austin, and Caroline will represent the EA community.
The sanction against Manifund that Zachary Robinson announced yesterday is a great start. But there are additional straightforward steps that can and should be taken to dissociate effective altruism from the financial corruption Austin just committed and the financial crime Caroline committed and served prison time for.
If the EA community can't agree that financial corruption or financial crime is an ethical red line and won't take decisive action to discourage it, the EA community should be correctly understood — by everyone, including both community insiders and outsiders — as ethically compromised.
It's not really about how things look. It's about how things are. Caroline really did steal money. Austin really did reward her for it.
The EA community should not tolerate this:
Answers:
There are no controls because Manifund is only Austin Chen and Caroline Ellison, so this is 100% trust-based. I am concerned about the risk of Caroline Ellison committing financial crimes again. I take it many others are concerned about this risk as well. Between here and Austin's Substack post, some comments have explicitly expressed their concern that this is an unnecessary risk, e.g., noting how high recidivism rates are even when recidivism seems completely irrational. Beyond that, there is also the corruption aspect, which is not just a risk or a possibility — the corrupt quid pro quo has already occurred. That horse is out of the barn.
What an off-base thing to say. Caroline just got out of federal prison for one of the largest financial crimes in recent American history. Austin said one of the motivations for the hire is to reward her for the money FTX gave to Austin's organizations in the course of committing these crimes. It looks completely insane and corrupt because it is completely insane and corrupt. What are you talking about?
What?? The only way to get top talent for financial roles is to hire people who have been convicted of financial crimes?? What are you talking about?!
I don't know what specific people you're referring to or the mistakes (as you put it) they made. So, I can't comment.
People are being quite honest, open, and direct about the fact that trust and reputation are a big concern here, among other concerns such as corruption and increasing the risk of future financial crimes involving EA money. Who is pretending?
The philosopher David Thorstad's recent blog post methodically goes through the multiple different concerns with this hire, point by point. David has a commendable amount of patience in explaining things like this.
Hi Bruce! I recently attended a Zoom book talk you gave and I really enjoyed it. :)
My answer to your question:
It can be frustrating when people just click disagree and don't explain why, but I don't know that making agree and disagree votes non-anonymous would make much difference. I assume if people want to explain why they disagree they'll write a comment, and if they don't they won't. If disagree votes were non-anonymous, would it result in more people writing comments explaining why they disagree? Well, why would it?
In my view, agree and disagree votes and karma upvotes and downvotes are not all that meaningful, anyway. I find them be a hard-to-ignore distraction from meaningful engagement with people through words, rather than votes. If you create a points system, everybody wants to go for a high score, but that's not the point of a forum.
Overall I would generally just caution people from investing much time or emotional energy in the EA Forum. It's a perfectly fine place to post announcements for organizations like the Good Food Institute and answer questions. In terms of actual deep, meaningful discussion, it's better to seek out — or even create — alternatives. The culture here is sour and trollish. Rather than enforcing norms of civility, the moderators encourage and even engage in the bad behaviour themselves. The only hope I can see of this changing would be if the Centre for Effective Altruism were to choose new people to run the forum who were committed to changing the culture. But what are the odds of that happening?
Anyway, that's a bit of a digression.
Thank you, Zachary. I admire the integrity of this eloquent and incisive comment, and I admire even more that it comes with a concrete action attached. Hallelujah.
There is an additional consideration beyond what you mentioned: Austin Chen received $1.5 million in stolen cash from Caroline Ellison, Sam Bankman-Fried, and others at FTX. Austin gave Caroline Ellison a job at Manifund as a reward, a repayment for this stolen cash — a repayment for the debt he feels he owes to her, as he put it. I'm not speculating on his motive; this is what Austin said, openly.
Austin is currently being sued by the FTX Recovery Trust (which represents FTX's creditors) because they want that $1.5 million back. Unlike others in Austin's position, he decided he wanted to keep that stolen cash. And he decided he wanted to reward and thank one of the people who stole it for stealing it for him. His words:
This is just straight-up corruption.
Austin has repeatedly defended FTX executives generally and Sam Bankman-Fried in particular over the last 4 years. As recently as April 2025, Austin said:
What a brazen embrace of criminality. And he put his money where his mouth is when he hired Caroline.
It's a fantastic first step to ban Manifund booths from events run by the Centre for Effective Altruism. Thank you for that. Can I suggest two further steps?
One, ban Austin and Caroline from attending these events (even if they're not setting up a booth). Two, ban Austin and Caroline from the EA Forum. (Yes, she has an account.)
No single entity controls the entire EA ecosystem, and there's only so much even the CEO of the Centre for Effective Altruism can do. But presumably you can do this.
I don't know what else you might be doing behind the scenes, but if you haven't considered it already, you could consider talking to leaders of other organizations to encourage them to take more steps to dissociate effective altruism from Manifund, Manifold, Austin, and Caroline. This moment is a time to show whether the EA community meant any of the things it said in the wake of FTX's collapse, or if it was all talk.
A Christian, a Buddhist, and an effective altruist walk into a bar. The Devil appears and offers to buy their souls.
The Christian says, “My soul is worth more than all the treasures of the world, so there is no price you could pay me,” and leaves.
The Buddhist says, “The soul is an illusion, so I have nothing to sell you,” and leaves.
The effective altruist says, “I'll take a cheque for $1.5 million made out to Manifold Markets Inc. and, by the way, we're hiring.”
In addition to those comments you quoted from November 2022, Austin made similar comments in April 2025:
And:
It's worth noting that Austin is being sued by the FTX Recovery Trust for $1.5 million that Sam Bankman-Fried, Caroline Ellison, et al. gave him out of stolen customer funds. Austin explicitly said in his announcement:
So, this decision to hire Caroline Ellison is because Austin supports her and SBF's criminal conduct and wants to reward it because he got $1.5 million out of the arrangement. It's corruption. What's remarkable is that the corrupt intent is so openly stated.
If the effective altruism community at large stands by this, no one will be able to say: 'we didn't know any wrongdoing was occuring; we honestly thought everything was above board.' The corruption is happening now in plain sight.
How empty everything said about FTX in defense of EA will be if the community doesn't eject Manifund and Austin when he openly pays Caroline Ellison with the money she stole as a reward for stealing it.
Turnabout is fair play.
(source)
“We should free SBF and put him to work.” –Austin Chen (2025 interview)
“I felt a keen debt to the FTX Future Fund. They provided seed funding for Manifold.” –Austin Chen on why he hired Caroline Ellison
After some reflection, I realized what may be the worst part of this decision.
Austin Chen has decided to reward and endorse Caroline Ellison's crimes at FTX by giving her a job in exchange for the stolen money that FTX gave to Manifund. Austin explicitly said that this decision is out of "debt" to Caroline for the ill-gotten money FTX gave to Manifund. Austin's explicitly stated reasoning is: commit crimes that benefit me and I'll reward you.
Previously, Austin harshly criticized the EA community for its supposed disloyalty to Sam Bankman-Fried in the wake of the revelations of FTX's fraud.
In November 2022, Austin wrote of people in EA who denounced or dissociated themselves from Sam Bankman-Fried:
In April 2025, Austin said:
And:
This is a corrupt way to think. This is putting money above ethics.
If someone gives you $500,000 they stole and because of this (not in spite of it!) you give them a job in return, what else is this than corruption? What else is this than a reward for the crime? And an endorsement of the crime?
Nobody can control Austin's decisions and maybe nobody can change his mind. But EA organizations and individual members of the EA community can decide whether you can encourage criminality and engage in corruption and still be a part of the EA community. I think Austin and Manifund should be thrown out, along with Austin's other projects, Manifold and Manifest.
Enough is enough. The line has to be drawn here.
If you're wondering what it would mean to throw Austin and Manifund out of the EA community, here are some steps that could be taken:
Only a few people have the ability to ban people from EA conferences or the EA Forum. But there are some steps anyone can take:
The EA community has the power to decide who it includes and who it excludes. It therefore has the moral responsibility for those decisions. Criminality and corruption should not be tolerated in the EA community.
