COSMOS was such a great summer school! The perfect environment to learn about research on different aspects of collective life from social learning to decision-making- I had a lot of fun. Can only recommend COSMOS to any PhD student or postdoc interested in the computational modeling of collectives!

Had a great time meeting and learning from researchers in the fields of cultural evolution, collective intelligence and psychology in the COSMOS summer school held in the beautiful city of Tokyo. Thanks a lot to the amazing duo @watarutoyokawa.bsky.social & @thecharleywu.bsky.social for organizing!

Mayuko Nakamaru pointed what if gossips, a said-to-be key mechanism of human indirect reciprocity, have lies. Her evo. models seem to have many rooms to be addressed by cognitive models too! #cosmos2025

Intervening on a central node in a network likely does little given that its connected neighbors will "flip it back" immediately. Happy to see this position supported now.

"Change is most likely [..] if it spreads first among relatively poorly connected nodes."
