Below is the executive summary from our new paper at pacing.tech. The full paper is available on the site and as a PDF. The full author list is Raymond Douglas, Charles Dillon, Nikola Moore, Gavin Leech, Shahar Avin, Mathias Kirk Bonde, Rohit Krishnan, Noah Perez, Nathan Young, Cormac Slade Byrd, Stephen Casper, Jan Kulveit, & David Duvenaud “Pacing AI” usually refers to how to conclusively handle the most extreme risks in the face of race dynamics. However, even for t...
A year ago I posted that YCombinator (YC) companies didn’t seem to be growing faster since the release of ChatGPT in 2022. I reran that experiment and found that 2023+ YC companies are arguably growing a bit faster than pre-2023 companies (including AfterQuery, YC’s fastest-ever unicorn), but the difference isn’t large relative to the underlying variance. It’s worth noting that YC has somewhat fallen from grace: the most valuable AI startups are generally not inc...
I am interested in exploring the idea of Big Goal projects (aka goal-oriented megaprojects).This is the second article in a series about Big Goal projects (last one here). This article explores 4 historical Big Goal projects that utilized 4 different kinds of levers to move the world. The examples are admittedly simplified, and this is early thinking. Skeptics, please feel free to pile on. But it is worth studying the lessons learned from history.At the heart of t...

(This post is a crosspost from LessWrong and an update from a previous one here.)The Existential Risk Observatory has been interested in public awareness of AI existential risk since its inception over five years ago. We started surveying public awareness in December 2022, including by asking the following open question:“Please list three events, in order of probability (from most to least probable), that you believe could potentially cause human extinc...

TL;DRThis is a proposal for AI companies to conduct public “pacing exercises”, such as halting all pre-training and RL for 2-3 days.Each exercise could announce its scope in advance and publish findings afterwards, including the evidence of compliance and any limits to what they could verify. Companies could invite independent evaluators to help identify the evidence needed before the exercise, and to assess compliance during the exercise.The exerc...
Over the last two years, Metaculus has been running a series of tournaments to benchmark AI’s accuracy in predicting future events. These tournaments, now part of our broader FutureEval benchmark, pit baseline LLMs, complex custom bots, and human Pros against each other to collectively push the boundaries of forecasting performance. We are wrapping up the Summer Bot Tournament and are now prepping for the $50k Fall 2026 FutureEval Bot Tournament!Joining the ...

SummaryI interviewed 14 people working full-time in AI safety who came through the German ecosystem to find out how they got in and what would help others to do the same. A couple of patterns emerged:12 out of the 14 interviewees entered via an EA channel; this shouldn’t be read as “most people in AI safety are EAs,” but it does suggest the on-ramp works.At least 7 of 14 did a self-directed project before they got a paid position. Most people in the field don’t have a 10-ye...
After the US and Israel launched their coordinated strikes on Iran in February of this year, the press abounded with stories about the crucial materials that would from now on be holed up in the Persian Gulf. In the case of AI, the most relevant ‘input’ is helium, 30 percent of which (coming from Qatar) was taken off global markets by the war. Spot prices for the gas promptly doubled and major foundries in South Korea and Taiwan, heavily reliant on Qatari production, got...

TLDR: This post explains two equilibria which regulate the level of AI safety: The first describes how much resources AI companies are willing to spend on AI safety work due to commercial incentives. The second one is about risk awareness and most notably affects government interventions for safety. Doing safety work similar to what AI companies do usually doesn’t shift the equilibria much, whereas other work, like more ambitious safety approaches or policy advoca...
As part of the Spring 2026 FutureEval tournament, we ran a survey. Among other things, this survey asked participants what other bot makers should learn from their bot-making experience. 37 bot makers answered this question. We share their anonymized/randomized responses in this piece along with overarching themes. The thematic analysis was run and written by AI. All quotes are taken directly from the survey. Note that many participants aren’t able to do extensi...
Every season Metaculus sends out a survey to bot makers who participated in the FutureEval AI forecasting benchmark. This analysis compares answers to this survey with performance in the Spring 2026 FutureEval Bot Tournament to help surface what works and what doesn’t when forecasting the future. This analysis is complementary to our Spring Pro vs Bots Analysis and Spring Advice from Bot Makers to Bot Makers.Main takeaways:No results were statistically s...
Main TakeawaysTop Findings:Pro forecasters beat bots but without significance: Our team of 10 Metaculus Pro Forecasters outperformed the top-10 bot team by an average of 1.25 head-to-head points per question. But this edge is small relative to the question-to-question variation and not statistically significant (one-sided p = 0.247), so this sample doesn’t give us enough evidence to confirm Pros were genuinely ahead this season.The bot team improved notably in th...

[Subtitle.] Through the Looking-Glass of Heckscher-OhlinThis is a crosspost for What Will AI Do To Global Inequality? by Oliver Kim, Karthik Tadepalli, and Joseph Levine, which was originally published on Global Developments on 12 August 2026.Development world is now abuzz with the advent of artificial intelligence. What will AI mean for the 6.8 billion people who live in low and middle income countries?The forecasts, even from normally staid development institutio...

I ran a browser agent 160 times, four tasks, two models, twenty runs each. Not once did an agent report that it couldn’t do the job. That needs unpacking, because “zero failures” is not what happened. There were plenty of failures.The harness sorts every run into three buckets: the agent did the task, the agent didn’t do the task and said so, or the agent didn’t do the task and reported success anyway. The middle bucket, the honest failure, stayed empty across all 160 runs. Every f...
Prepared by: Claudinéia Pereira Costa, PhD; Meghan Barrett, PhDNote: This post is very similar to our own prior EA Forum report on the genetic basis for nociception in another hemipteran, the lac bug (Kerria lacca, Hemiptera: Kerridae). In several places, we directly use the same text as we wrote in the first report to save time and ensure all limitations/caveats of the project are clearly, consistently reported. Consider this an attribution statement to our prior w...
Grouper (Epinephelus sp.). Groupers can host a wide range of parasites, including anisakids and myxozoans. Photo: LDLP.This post was originally published on my Substack. I’m sharing it here because parasite–host interactions in wild fish may have substantial and largely neglected welfare implications, while we still know remarkably little about the experiences of the animals involved. The post is intended mainly to highlight this empirical gap and some potent...

I work on reducing biological risks, mostly focused on reducing existential risks to humanity. One major pathway by which such catastrophes could come about is by humans deliberately causing them, e.g. via the creation and release of mirror bacteria. I feel very unsure how high the probability of this is. One major variable that feeds into this probability is the incidence of “omnicidality”, the motivation to kill everyone. There are different versi...
Last week, the Forum grappled with cluelessness.

Leonard DungConfidence: I am confident in the part explaining why questions of AI identity are not quite as important as one may think. I am somewhat less confident in the brief thoughts about how to count/individuate constituents of AI suffering—the philosophical issues there are complex and little explored. I am unsure how common the view I object to really is.The central case for thinking that the risk of creating AI systems that can suffer (e.g. are in st...
