Are humans really the only rational animals? Our NEW PAPER 🎉 out in @science.org suggests otherwise! In a large collaboration led with my joint first author @hanna-schleihauf.bsky.social, we show that “Chimpanzees rationally revise their beliefs” 🧵
Chimpanzees rationally revise their beliefs
The selective revision of beliefs in light of new evidence has been considered one of the hallmarks of human-level rationality. However, tests of this ability in other species are lacking. We examined...

Frontier AI could reach or surpass human level within just a few years. This could help solve global issues, but also carries major risks. To move forward safely, we must develop robust technical guardrails and make sure the public has a much stronger say. superintelligence-statement.org

Minds, Artificial Intelligence, and Ethics
October 14, 15, and 16, 2025 What is the potential of AI to alleviate suffering, advance equity, and support human and planetary flourishing—and what risks does it pose to health, work, education, politics, and climate action?

Excellent advice but also: sign your review. Whether you actually sign it (I have for the last decade) or not, just thinking about it will nudge your review towards a more generous consideration of the authors, working to help them improve the paper rather than offering scathing criticism.
For all the knucklehead reviewers out there.

in case you wanted at least a bit of good news today
Germany’s wind & solar surge in June 2025 is huge.

Share of generation: 57.5% — up from 47.7% in June 2024, and double the 28.8% in June 2021.

Output: 21.1 TWh, a 33% YoY jump from 16.6 TWh.

World’s 3rd-largest economy — a clear sign that high renewables penetration at scale is already happening.

So much of media is bad news. And I think it’s intended to break your will. I think it’s important to purposely spend time to expose yourself to good news and things that improve your spirits. In simpler terms, put yourself in your own happy place. It makes you a better fighter.

Apparently we’re just fancy thermostats (OK, that’s a bit of an exaggeration). At least that’s the analogy Herbert Harris uses to explain active inference as the underpinnings of our sense of free will.
