🗞️📣 New paper "Exact conditions for evolutionary stability in indirect reciprocity under noise" with @chilbe.bsky.social & @yohm.bsky.social
How can cooperation persist in large groups of unrelated individuals? Reputation 🗣️ But which social norms make this stable, even when mistakes happen?

Exact conditions for evolutionary stability in indirect reciprocity under noise
Author summary Understanding how cooperation can evolve and be sustained is a central question in evolutionary biology and social science. One prominent explanation is indirect reciprocity, where indi...

I updated the rb_call library, which allows you to call Ruby methods from Python code. It now works with the latest version of Python.
