Since January I’ve applied to ~25 EA-aligned roles. Every listing attracted hundreds of candidates (one passed 1,200). It seems we already have a very deep bench of motivated, values-aligned people, yet orgs still run long, resource-heavy hiring rounds. That raises three things: Cost-effectiveness: Are months-long searches and bespoke work-tests still worth the staff time and applicant burnout when shortlist-first approaches might fill 80% of roles faster with decent candidates? Sure, there can ...

This is a link post. I donated my left kidney to a stranger on April 9, 2024, inspired by my dear friend @Quinn Dougherty (who was inspired by @Scott Alexander, who was inspired by @Dylan Matthews). By the time I woke up after surgery, it was on its way to San Francisco. When my recipient woke up later that same day, they felt better than when they went under. I'm going to talk about one complication and one consequence of my donation, but I want to be clear from the get: I would do it again in ...

Hi all, This is a one time cross-post from my substack. If you like it, you can subscribe to the substack at tobiasleenaert.substack.com. Thanks Gaslit by humanity After twenty-five years in the animal liberation movement, I’m still looking for ways to make people see. I’ve given countless talks, co-founded organizations, written numerous articles and cited hundreds of statistics to thousands of people. And yet, most days, I know none of this will do what I hope: open their eyes to the immensity...

Summary In this article, I argue most of the interesting cross-cause prioritization decisions and conclusions rest on philosophical evidence that isn’t robust enough to justify high degrees of certainty that any given intervention (or class of cause interventions) is “best” above all others. I hold this to be true generally because of the reliance of such cross-cause prioritization judgments on relatively weak philosophical evidence. In particular, the case for high confidence in conclusions on ...

About the program Hi! We’re Chana and Aric, from the new 80,000 Hours video program. For over a decade, 80,000 Hours has been talking about the world's most pressing problems in newsletters, articles and many extremely lengthy podcasts. But today's world calls for video, so we’ve started a video program[1], and we’re so excited to tell you about it! 80,000 Hours is launching AI in Context, a new YouTube channel hosted by Aric Floyd. Together with associated Instagram and TikTok accounts, the cha...

Epistemic status: This post — the result of a loosely timeboxed ~2-day sprint[1] — is more like “research notes with rough takes” than “report with solid answers.” You should interpret the things we say as best guesses, and not give them much more weight than that. Summary There's been some discussion of what “transformative AI may arrive soon” might mean for animal advocates. After a very shallow review, we’ve tentatively concluded that radical changes to the animal welfare (AW) field are not y...

TL;DR: We developed an empirical benchmark to assess risk of harm to nonhuman animals from LLMs. Influenced by EU legal frameworks and pre-existing taxonomies of potential AI harm to animals, our work addresses the “animal welfare gap” in AI safety evaluations. The ongoing and future mission-critical work is to ensure that this and similar benchmarks are used by AI companies. The aim of this post is to introduce you to AnimalHarmBench, the first standardized LLM eval to assess the level of risk ...

This is a link post. I wrote a reply to the Bentham Bulldog argument that has been going mildly viral. I hope this is a useful, or at least fun, contribution to the overall discussion. “One pump of honey?” the barista asked. “Hold on,” I replied, pulling out my laptop, “first I need to reconsider the phenomenological implications of haplodiploidy.” Recently, an article arguing against honey has been making the rounds. The argument is mathematically elegant (millions of bees, fractional suffering...

Once we expand to other star systems, we may begin a self-propagating expansion of human civilisation throughout the galaxy. However, there are existential risks potentially capable of destroying a galactic civilisation, like self-replicating machines, strange matter, and vacuum decay. Without an extremely widespread and effective governance system, the eventual creation of a galaxy-ending x-risk seems almost inevitable due to cumulative chances of initiation over time and across multiple indepe...

If you are planning on doing AI policy communications to DC policymakers, I recommend watching the full video of the Select Committee on the CCP hearing from this week. In his introductory comments, Ranking Member Representative Krishnamoorthi played a clip of Neo fighting an army of Agent Smiths, described it as misaligned AGI fighting humanity, and then announced he was working on a bill called "The AGI Safety Act" which would require AI to be aligned to human values. On the Republican side, C...

TL;DR: You can create outsized value by introducing the right people at the right time in the right way. This post shares general principles and tips I've found useful. Once you become a super connector, it's also important to be a good steward of the unavoidable whisper networks that develop, and I include tips for that as well. Context: I unintentionally fell into a super connector role and wanted to share the lessons I figured out along the way. Feel free to check out my personal story[1] and...

I’ve been meaning to write about this for some time, and @titotal's recent post finally made me do it: Thick red dramatic box emphasis mine. I was going to post a comment in his post, but I think this topic deserves a post of its own. My plea is simply: Please, oh please reconsider using adjectives that reflect a negative judgment (“bad”, “stupid”, “boring”) on the Forum, and instead stick to indisputable facts and observations (“I disagree”, “I doubt”, “I dislike”, etc.). This suggestion is mot...

Earlier this year, we launched a request for proposals (RFP) from organizations that fundraise for highly cost-effective charities. The Livelihood Impact Fund supported the RFP, as did two donors from Meta Charity Funders. We’re excited to share the results: $1,565,333 in grants to 11 organizations. We estimate a weighted average ROI of ~4.3x across the portfolio, which means we expect our grantees to raise more than $6 million in adjusted funding over the next 1-2 years. Who's receiving funding...

This is a link post. Thank you to Arepo and Eli Lifland for looking over this article for errors. I am sorry that this article is so long. Every time I thought I was done with it I ran into more issues with the model, and I wanted to be as thorough as I could. I’m not going to blame anyone for skimming parts of this article. Note that the majority of this article was written before Eli's updated model was released (the site was updated june 8th). His new model improves on some of my objections, ...

Formosa: Fulcrum of the Future? An invasion of Taiwan is uncomfortably likely and potentially catastrophic. We should research better ways to avoid it. TLDR: I forecast that an invasion of Taiwan increases all the anthropogenic risks by ~1.5% (percentage points) of a catastrophe killing 10% or more of the population by 2100 (nuclear risk by 0.9%, AI + Biorisk by 0.6%). This would imply it constitutes a sizable share of the total catastrophic risk burden expected over the rest of this century by ...

This is a transcript of my opening talk at EA Global: London 2025. In my talk, I challenge the misconception that EA is populated by “cold, uncaring, spreadsheet-obsessed robots” and explain how EA principles serve as tools for putting compassion into practice, translating our feelings about the world's problems into effective action. Key points: Most people involved in EA are here because of their feelings, not despite them. Many of us are driven by emotions like anger about neglected global he...

Crosspost from my blog. Content warning: this article will discuss extreme agony. This is deliberate; I think it's important to get a glimpse of the horror that fills the world and that you can do something about. I think this is one of my most important articles so I’d really appreciate if you could share and restack it! The world is filled with extreme agony. We go through our daily life mostly ignoring its unfathomably shocking dreadfulness because if we didn’t, we could barely focus on anyth...

This is a link post. I am deeply saddened to share that Gabrielle Young, a much-loved member of the EA NZ community and personal friend, died last month. This is an absolutely devastating loss, and our hearts go out to Gabby's friends and family, including her parents and her sister Brigette. While most of us knew her through EA, Gabby was an incredibly vibrant person with a diverse range of interests. She brought an infectious enthusiasm to everything she did, from software development to parko...

Crosspost from my blog. I just got back from Effective Altruism Global London—a conference that brought together lots of different people trying to do good with their money and careers. It was an inspiring experience. When you write about factory farming, insect suffering, global poverty, and the torment of shrimp, it can, as I’ve mentioned before, feel like screaming into the void. When you try to explain why it's important that we don’t torture insects by the trillions in insect farms, most pe...

Crossposted from my blog. When I started this blog in high school, I did not imagine that I would cause The Daily Show to do an episode about shrimp, containing the following dialogue: Andres: I was working in investment banking. My wife was helping refugees, and I saw how meaningful her work was. And I decided to do the same. Ronny: Oh, so you're helping refugees? Andres: Well, not quite. I'm helping shrimp. (Would be a crazy rug pull if, in fact, this did not happen and the dialogue was just p...

Mental illness (including struggles that don’t meet a specific diagnosis) is a serious public health burden that affects a large proportion of people. This is true within EA as well as in the general population. In EA, as in any community, it's important for us to try to support those who are struggling. We sometimes see the theory that EA causes unusually bad mental health, but the evidence lightly points toward EA being good or neutral for the wellbeing of most people who engage with it. Most ...

Around 1 month ago, I wrote a similar Forum post on the Easterlin Paradox. I decided to take it down because: 1) after useful comments, the method looked a little half-baked; 2) I got in touch with two academics – Profs. Caspar Kaiser and Andrew Oswald – and we are now working on a paper together using a related method. That blog post actually came to the opposite conclusion, but, as mentioned, I don't think the method was fully thought through. I'm a little more confident about this work. It es...

Summary While many people and organisations in the EA community can be great connections, don't assume that just because a person has been in the EA community for a long time, they'll be a good fit for you to work with or be friends with.

Article 5 of the 1948 Universal Declaration of Human Rights states: "Obviously, no one shall be subjected to torture or to cruel, inhuman or degrading treatment or punishment." OK, it doesn’t actually start with "obviously," but I like to imagine the commissioners all murmuring to themselves “obviously” when this item was brought up. I’m not sure what the causal effect of Article 5 (or the 1984 UN Convention Against Torture) has been on reducing torture globally, though the physical integrity ri...

Introduction I have been writing posts critical of mainstream EA narratives about AI capabilities and timelines for many years now. Compared to the situation when I wrote my posts in 2018 or 2020, LLMs now dominate the discussion, and timelines have also shrunk enormously. The ‘mainstream view’ within EA now appears to be that human-level AI will be arriving by 2030, even as early as 2027. This view has been articulated by 80,000 Hours, on the forum (though see this excellent piece excellent pie...

Are you looking for a project where you could substantially improve indoor air quality, with benefits both to general health and reducing pandemic risk? I've written a bunch about air purifiers over the past few years, and its frustrating how bad commercial market is. The most glaring problem is the widespread use of HEPA filters. These are very effective filters that, unavoidably, offer significant resistance to air flow. HEPA is a great option for filtering air in single pass, such as with an ...
