Effective altruists advocate giving your money to where it does most good. The leading areas EAs recommend donating to are making the long-term future go better, animal welfare, global health, and growing the effective altruism movement. Yet there’s been surprisingly little comparison between these cause areas. Here, I’ll explain my ranking: why I think it’s best to donate to Longtermist organizations or organizations focused on growing EA. I’ll also explain why I think animal welfare is bett...
This is a new episode of the GiveWell Conversations podcast. You can listen to the episode or read a summary of the conversation below.

This week is a big one for the lead poisoning community. The TED Talk I gave in April about lead poisoning just went live, and it's nearly at 100,000 views. Watch it here:
In the talk, I describe a crisis affecting more than one billion children, the toll it takes on their health and futures, and the main sources of exposure. Most importantly, I share our path to solving it.
This momentum did not evolve by...
I wonder how much attending different universities matters if we focus solely on the quality of research mentorship available to an EA-oriented student who hopes to reduce AI risks.
I plan to study dentistry at a medical university because I believe having earn-to-give as a backup option is important. However, my ultimate goal is to become an AI safety researcher. I therefore plan to collaborate with computer science professors at a nearby university an...
I’m still sceptical about your plan on pursuing two very different careers in parallel. It’s not an issue if EtG is important to you but I’m not seeing what justifies doing two in parallel? Why is it better than one person doing EtG and another doing CS?
On the original question, I think it’s very difficult to tell from the outside. You want to do projects to gain experience that lets you enter certain roles (e.g. entry AI safety roles). The people hiring for such roles are the ones who can tell what they are looking for and how people usually get there.
“How long have you been v*g*n?”
This is one of the most common icebreakers at animal protection events. It’s a baseline assumption, and it mostly holds true: if you’re out advocating for animals not to be tortured or abused, realistically these days you are v**n, or close. And it makes for good conversation. It seems fairly safe to assume when you meet strangers.
But this assumption is hurting the movement in a way which we don’t always notice: someone new comes into the sp...
I agree that veganism is getting in the way of animal advocacy. This post makes great points about how veganism alienates the vast majority of humanity. And to me, veganism's effect on the majority of humanity is actually just the tip of the iceberg of the problem of how veganism harms animals:
To people in the meat, egg, and dairy industries, veganism is worse than alienating. It's a direct threat. To someone who makes their living in animal agriculture, the word "vegan" can sound like an attack. "Vegan" can sound like, "I am boycotting all animal products because I want you, your company, and your entire industry to go out of business. I want you to fail at everything you're trying to achieve and lose your livelihood. I hate you, all your colleagues, and your family. I think you are all fundamentally evil."
That's not a very friendly message to hear. It doesn't open a farmer, farm worker, or ag executive up to want to collaborate with animal advocates. It doesn't open a poultry-industry veterinarian up to want to consider an animal advocate's perspective. Imagine how scary it would feel to hear a message like that. Imagine how little you'd want to network with, collaborate with, or be influenced by, someone who sends you that kind of message.
Meanwhile, the best thing for animals would be maximal collaboration and communication between animal agriculture and animal advocates. Farmers, ag executives, and others in the meat, egg, and dairy industries are the ones who have the most power to influence animals' lives for the better. They are the most important audience for animal advocates to speak with. And they are the most important people for us to learn from. So why should we animal advocates constantly threaten them each time we open our mouths?
Nice post; upvoted. I definitely agree that on the margin it would be helpful for vegans to accept and encourage anyone who wants to help animals, and invoking veganism as a litmus test is almost always counterproductive for that.
That said, the framing of veganism as a curse word seems over-corrective to me. Following the “vegans are monks” analogy, telling someone I’m a “monk” in the right social context is positive signaling about my moral seriousness. Learning someone is a “monk” strongly updates me in favor of their moral seriousness. And yes, there are social situations where if you have a friend who’s the right kind of person, it can be acceptable to ask whether they’re interested in “taking the monastic vows”. Rather than avoiding invoking veganism entirely, I’d suggest people be more deliberate about invoking it only when they think it’s genuinely helpful.
As a non-vegan, if people tell me they're vegan I won't necessarily feel judged but can ensure they get a reasonable choice of food they will feel comfortable eating
Whereas if they describe themselves as a "pro-animal person" it sounds like someone who likes puppies (or if activism is implied, potentially more extreme than vegans, though of course that very much depends on how much they elaborate!). Alternatives like "I prefer plant-based food" sound like a taste preference or fad diet.
"uh-oh, I’m realizing everyone else here is v**n, I probably need to be very cautious about what I reveal about myself, do I need to hide?"
I would say, as a lacto-vegetarian who goes to vegan events, I never felt this way, though I can see how someone could. When asked, "How long have you been vegan?" I clarify that I'm not vegan -- that I've been vegetarian since January, and, sometimes, that I am thinking about going vegan -- and I ask them the question back. Sometimes they're vegan, sometimes they're not! But it's always a nice icebreaker and a fun experience; it's never been negative for me.
I also think a non-vegan answering the question and hearing back, "That's completely fine!" or "Oh, that's cool, I'm flexitarian myself, actually!" shows that the "vegan" community is not just for vegans but for all animal people.
And I do like “animal people” as a term, though. Sounds cool.
I'd also suggest "So, what's your story?" / "What brings you here?" as an icebreaker, where the context of being at an animal-people event makes it clear what you're asking, without assuming much.
in my personal experience people who care about animals and want to help them but eat animal products often show a lot of cognitive dissonance and motivated reasoning
This sounds plausible to me, though fwiw I also think that this stereotype is another that makes it hard for omnivores to feel fine in animal welfare spaces. I kind of hate people assuming simply from my diet that probably I'm making epistemic mistakes that I refuse to acknowledge, or that I'm pretending to care about animals when I actually don't.
Obv I agree there's a strong desire not to turn to the cruelty of your own diet. I think figuring out how to allow ourselves and help each other to live with the terrible suffering in the world we're not doing things about is one of the big challenges of effective altruism.
This is a linkpost for Subjective Probabilities should be Sharp by Adam Elga, which was originally published in Philosophers' Imprint in May 2010. Here is an errata for it. Below is a summary...
Right. I think using unsharp probabilities, and expected values is fine to highlight it is unclear which of the interventions being compared has the highest expected cost-effectiveness. However, I do not see what is the advantage of this relative to just getting wide distributions for the cost-effectiveness, and showing these overlap a lot, which would be a sign that decreasing their uncertaity may have a higher expected cost-effectiveness than picking the intervention with the highest expected cost-effectiveness. One can analyse value of information (VOI) using perfectly sharp credences.
This is some very old work I never published in the EA forum; publishing it now because I want to add it to my Estimating value series, mark the end of an era & reference it elsewhere. I don't think I could produce this work today since I've lost the youthful innocence to think it'd be worth the effort given the idosyncrasies of funding institutions. Thanks to SoGive for commissioning this piece a few y...
Executive summary: The author argues that funding decisions for existential risk interventions should rely on practical, estimate-based cost-effectiveness thresholds rather than impracticable ideal methods or unstructured expert judgment, and proposes tentative upper and lower funding thresholds grounded in first-principles reasoning and comparisons with existing interventions.

A ~month ago I left from Chicago to bike (and amtrak) to plzdontkillus in Berkeley. I've been street interviewing/conversing with a wide variety of people I ran into about AI futures and philosophy. I also have been live streaming since I got to PDKU, leaning more talking to young founders but a variety overall.
I'll try to share what I've learned about the Amer...
Thanks for the kind words!
Responding to point 4, I think your response is extremely fair and basically correct, it's a bit unfair for me to criticize EA for not being something that it obviously isn't. But I think my response to that is very relevant to you, which is that you should be thinking about what you want EA to be. Should EA be a library, that doesn't weigh in or put it's resources behind specific interventions? Or on the other end, it could be extremely "active". I think right now it's somewhere in the middle, which isn't necc bad but always confusing to me. Like you could say "look EA isn't going to get political that's out of scope" but isn't choosing who speaks at EAG political? isn't giving resources for fellowships that are at minimum utilitarian adjacent political? Why is the line teaching people applied utilitarianism and not directly being an activist organization?
Not saying it should be one or the other but hope people keep thinking about this stuff.
Hey Charlie, you're a legend for this. One thing I will add is for easy video editing is to use CapCut and then auto-generate subtitles. You can export to 1080p and that gives the quality people are used to seeing for your types of videos.
Not going to lie, a few vids were grainy and almost all of them didn't fit the frame. This is an easy fix if you can spare $10 a month to edit on CapCut.
Thank you for doing this work. I've been door-knocking to message-test for my advocacy organization. I very much agree there is very little "AI literacy" among most people in the US/the world.
Certain framings work well at activating people, like focusing on Big Tech & political corruption. The goal is, in my opinion, to make sure politicians/law-makers are AI-literate and the general public is directionally in support of AI safety.
You're very right that advocacy is severely neglected
Epistemic status: a fully parameterized Monte Carlo model whose every input is inspectable and overridable — not a measured fact. The cost-effectiveness anchors come from published causal studies; the judgment priors (evidence-credibility tiers, realization, allocation concentration) were drafted by Claude and reviewed by me, and each is a slider. I'd value attacks on specific parameters over general takes.
Update (July 13): A reader caught the model's biggest er...
Actually, we don't downrank them, we just auto-tag them as AI-generated (although this one hasn't run automatically- doh)
Would be interested in seeing a version of this that looks at WELLBYs or otherwise uses moral weights to holistically judge all of the portfolio's effects. But, this piece does seem like a convincing example of the idea the best charities are 100–1000× more effective than the average charity.
Thanks for the context but putting these caveats in the disclaimers doesn't change how the tool works.
The underlying studies are solid. The problem is the layer on top of them. The scores and weights are AI set guesses on a slider, not field data. Again, that's most true for the civic engagement, equity and justice buckets, which is where most of Scott's money goes. The author says himself those buckets get "wide skeptical priors" because no health pathway has credible evidence. That isn't a real effect adjusted for uncertainty. It's a number filling in for missing data. Since those are the biggest buckets, that number is doing a lot of the work behind the headline frontier multiple. The comparison is weakest exactly where most of her money sits.
That's my real concern. The tool takes her hardest to measure work and makes it look like it buys almost nothing, when that low number is a measurement gap, not a fact about the work. A model is only as strong as its weakest layer. For most of this portfolio, that layer is a guess standing in for how funding actually works on the ground, like whether a local coalition can absorb a sudden influx of cash, or the fact that structural change doesn't run in a straight line to a health outcome.
Flagging that in the fine print is good practice, but it doesn't fix it. The calculator is still running precise maths on top of guesses.
why not just try to measure utils instead of QALY?
In 2023-2024, it seemed a very strong bias from the EA community and the core AI safety funders that Anthropic not to be argued against or funding diverted to anything that was critical of them (directly or indirectly).
I wonder how the community and funders have updated their beliefs and behaviours?
I hastily vibecoded a ~live-updating EA Forum (posts + comments; I think users are static) database + semantic search because software is ~free now. I haven't rigorously checked anything over because it was/is just a random side project so use at your own risk and discretion. Enjoy!
Full database is ~17GB
Hi!
I haven't been very active on the Forum recently, so I thought I'd just pop in to remind people that I offer various editing-related services as a freelancer.
I'm based in London, but most of my work is remote. I offer copyediting, proofreading, substantive editing, conceptual support, review, and coaching. I've worked with many individuals and organisations in the EA and AI safety worlds: for example, I copyedited METR's recent Frontier Risk Report and the International AI Safety Report (2025 and 2026).
If you'd like to work with me, book a short meeting or email me at [email protected].
Mental health is one of the most widespread, impactable, yet neglected global health issues of our time. Even knowing mental health conditions are generally under-reported and/ or misrepresented, evidence still shows widespread effects of mental wellbeing on physical health, life satisfaction, and productivity, however it has still not taken off as a major cause area in many EA organizations I have talked to. Why is this?
I'm recording a podcast (TWCBB) with @Lauren Gilbert [edit: we had to reschedule so I can still collect questions]. If there's anything you'd like us to ask her, comment here.
I'm not involved in animal welfare, so I won't comment on whether broadening the tent and bringing in meat-eaters is a good thing. That said, if we take that as a given, I still find this solution of tabooing "vegan" rather strange. One direct comparison we could make here would be the 10% pledge. It seems like the community orients to the 10% pledge in much the same way you'd like people to orient towards veganism? It's a large commitment to your values. It's to be celebrated. People talk about it openly. But you aren't expected to have to sign the pledge in order to identify as EA, attend a meeting, post on the Forum, etc.
I would say it would be a very large mistake to taboo the 10% pledge entirely, and avoid mentioning it in polite company. There's a lot of gap between "Everyone must sign the 10% pledge, or you're not a real EA and should feel unwelcome here" and "Nobody should ever mention the 10% pledge in public, for fear of driving away newcomers". EA already seems to handle this well with how the 10% pledge is used. Why shouldn't that be the model for how to handle other large commitments that should be celebrated but not demanded?
Just as some feedback, I don’t think the usual objection to working on longtermism or GCRs is ‘it’s not valuable enough’, even from a general audience. I think it would be more persuasive to explain somewhere why working on these causes would achieve anything at all. It’s not clear from your post that there would be a relationship between effort and rewards, and I suspect a lot of people share the intuition that any counterfactually valuable work on the very long term future would be washed out or easily reversible.
Re Luna amendment, there was an additional Luna amendment that was trying to remove the SOB provision that died (even though the pesticide one went through). That was what I was referring to. https://www.nationalhogfarmer.com/farming-business-management/amendment-to-strike-down-save-our-bacon-act-rejected
You're right about 2, fixed. I didn't see the comment pointing this out as I don't check comments on posts more than a day after posting (otherwise I'd have way too many to check as I get a lot of comments).
Re 3, Didn’t mean to use the word PAC in the comment, was an error (not sure if I was confused at time or just a typo.). But the ampa themselves—not the PAC—are the things the donation link was to, and they’re just defeating sob. Other stuff the PAC is doing is also to defeat SOB (Craig is a big opponent of it).
And apart from the modal return being probably ~0 (which might not be a problem if funding lots of useless stuff guarantees sufficiently useful projects get funded), it is also possible for longtermist work to be actively counterproductive, with significant uncertainty around the direction as well as the magnitude of the impact of many longtermist activities[1]
Indeed many longtermist arguments strongly imply that work of other longtermists is counterproductive (it is hard to see how Anthropic and Pause AI can both be right about frontier models)
And even you're certain you've picked the correct side of a particular risk-mitigation debate, political donations and campaigning are particularly prone to provoke responses from opponents. This is true of a lot of campaigning, but "AI is very dangerous" is more easily inadvertently motivating accelerationists to act to militarise it first than "this suffering could be stopped" is pivoted into an argument for more cages or fewer bednets
there are probably exceptions to this; it's difficult to imagine that an asteroid early warning system will hurt us, even if it turns out to be useless
