A fun new preprint with the 🌟 team. We discuss 7 questions on mind perception we have been thinking and working on in the last years and it also features a picture of a dog! I mean what's more to like?

New preprint with @fabioladiana.bsky.social and Mariska Kret and collaborators reporting on two studies that explore the question if AI can trust us. How do patterns of dishonesty fluctuate across agents and pupil size in Japanese and European samples? Amazing work by @fabioladiana.bsky.social!

Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.

So normally I go to gigs at TivoliVredenburg, but yesterday I was standing on stage at the sold out Social Animal event at TivoliVredenburg organised by KLI and ASPO. I really felt like a rockstar. 🤟🤟🤟 Great evening with super cool talks and people. If you can, do visit it next year!

During 2023, Bitcoin's proof-of-useless-work mechanism consumed almost as much electricity as the entire traditional financial sector combined.
