Are humans the only rational animals? For thousands of years, we’ve thought so. Our new paper, out today in Science, suggests otherwise! We present evidence that chimpanzees possess several core capacities for rational thought. Check out Emily's thread: bsky.app/profile/emil...

Why do we derogate effective altruists, activists, & other radically prosocial individuals? In new work, we discuss how doing good that deviates from social norms gets stigmatized. New preprint w/ @dcameron.bsky.social @tlau.bsky.social @desmond-ong.bsky.social: osf.io/preprints/ps...

Never seen science conducted so thoroughly.

This is Thanos. He has figured out how to rest and babysit at the same time. Very impressive, very Montessori. 13/10 (TT: thanosthesaint)

Children build math skills on a “cognitive bridge” between space & number. But where does it come from? Our new study finds monkeys transfer learning and abstractions across geometry & numerosity, revealing the evolutionary roots of basic math development. 🧪🧠 www.pnas.org/doi/10.1073/...

“When people viewed virtual avatars with coughs or rashes, their brains triggered an immune response.” It would be fascinating to extend this research to people who don’t believe the diseases portrayed are communicable, and to animals that presumably don’t grasp germ theory.

Life would be so different if only my brain understood the difference between being chased by a large predator and completing a small task that shouldn’t take much time at all

Our new paper is out. We point out that large brained (and often smart) mammals and birds have evolved very different distribution of neurons numbers in the brain. This means that similar cognitive abilities have evolved in very different brains. www.sciencedirect.com/science/arti...

Two heroic stray dogs rescued an injured dog from the middle of the road by dragging him to safety. The dog had been hit by a car and was stranded. Many cars passed by, but it was two stray dogs who pulled him off the road. The injured dog survived, and the stray dogs were rescued. 15/10 for both
