This is a link post. There are some moments of your life when the reality of suffering really hits home. Visiting desperately poor parts of the world for the first time. Discovering what factory farming actually looks like after a childhood surrounded by relatively idyllic rural farming. Realising too late that you shouldn’t have clicked on that video of someone experiencing a cluster headache. Or...

My new book, Altruismo racional, is now on presale. It is my attempt at presenting a compelling case for a particular strand of "classical EA"[1]: one that emphasizes caring deeply about global health and poverty, a rational approach to giving, the importance of cost-effectiveness, and the 🔸10% Pledge. In this post, I provide some context on my reasons for writing this book and what I hope to ach...

Note: This post was crossposted from the Open Philanthropy Farm Animal Welfare Research Newsletter by the Forum team, with the author's permission. The author may not see or respond to comments on this post. Why ending the worst abuses of factory farming is an issue ripe for moral reform I recently joined Dwarkesh Patel's podcast to discuss factory farming. I hope you’ll give it a listen — and con...

I’m a long-time GiveWell donor and an ethical vegan. In a recent GiveWell podcast on livelihoods programs, providing animals as “productive assets” was mentioned as a possible program type. After reaching out to GiveWell directly to voice my objection, I was informed that because GiveWell's moral weights currently don’t include nonhuman animals, animal-based aid is not categorically off the table...

Giving What We Can has reached 10,000 🔸10% pledgers! We see this as an important milestone on the road to a cultural norm, and we’ve made a video to celebrate: If you’re a 🔸10% or 🔹Trial pledger, we’d love for you to post about the 10k milestone on your social channels! You can find templates here. And if you are a 🔸10% pledger, a sincere thank you for being part of the first 10,000! As our fo...

This is a link post. This is a personal essay about my failed attempt to convince effective altruists to become socialists. I started as a convinced socialist who thought EA ignored the 'root causes' of poverty by focusing on charity instead of structural change. After studying sociology and economics to build a rigorous case for socialism, the project completely backfired as I realized my politic...

Today, Forethought and I are releasing an essay series called Better Futures, here.[1] It's been something like eight years in the making, so I’m pretty happy it's finally out! It asks: when looking to the future, should we focus on surviving, or on flourishing? In practice at least, future-oriented altruists tend to focus on ensuring we survive (or are not permanently disempowered by some valuele...

This is a cross post written by Andy Masley, not me. I found it really interesting and wanted to see what EAs thought of his arguments. This post was inspired by similar posts by Tyler Cowen and Fergus McCullough. My argument is that while most drinkers are unlikely to be harmed by alcohol, alcohol is drastically harming so many people that we should denormalize alcohol and avoid funding the alcoh...

This morning I was looking into Switzerland's new animal welfare labelling law. I was going through the list of abuses that are now required to be documented on labels, and one of them made me do a double-take: "Frogs: Leg removal without anaesthesia." This confused me. Why are we talking about anaesthesia? Shouldn't the frogs be dead before having their legs removed? It turns out the answer is no...

Confidence Level: I’ve been an organizer at UChicago for over a year now with my co-organizer, Avik. I also started the UChicago Rationality Group, co-organized a 50-person Midwest EA Retreat, and have spoken to many EA organizers from other universities. A lot of this post is based on vibes and conversations with other organizers, so while it's grounded in experience, some parts are more speculat...

And other ways to make event content more valuable. I organise and attend a lot of conferences, so the below is correct and need not be caveated based on my experience, but I could be missing some angles here. Also on my substack. When you imagine a session at an event going wrong, you’re probably thinking of the hapless, unlucky speaker. Maybe their slides broke, they forgot their lines, or they...

This is Part 1 of a multi-part series, shared as part of Career Conversations Week. The views expressed here are my own and don't reflect those of my employer. TL;DR: Building an EA-aligned career starting from an LMIC comes with specific challenges that shaped how I think about career planning, especially around constraints: Everyone has their own "passport"—some structural limitation that affect...

I am writing this to reflect on my experience interning with the Fish Welfare Initiative, and to provide my thoughts on why more students looking to build EA experience should do something similar. Back in October, I cold-emailed the Fish Welfare Initiative (FWI) with my resume and a short cover letter expressing interest in an unpaid in-person internship in the summer of 2025. I figured I had a b...

This is a link post. Tl;dr: In this post, I introduce a concept I call surface area for serendipity — the informal, behind-the-scenes work that makes it easier for others to notice, trust, and collaborate with you. In a job market where some EA and animal advocacy roles attract over 1,300 applicants, relying on traditional applications alone is unlikely to land you a role. This post offers a tacti...

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 whe...

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 complicat...

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 p...

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 re...

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 Y...

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...

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...

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 be...

Is Morality ObjectivePlace your vote or view results. disagreeagree There is dispute among EAs--and the general public more broadly--about whether morality is objective.

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...

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...
