🗞️📣 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...

How to cooperate for a sustainable future? We don't know (yet), but I'm thrilled to share that our new perspective piece has just been published in @pnas.org. Bridging complexity science and multiagent reinforcement learning can lead to a much-needed science of collective, cooperative intelligence.

A little text about my journey with bipolar disorder. Seeing scientists speak openly about their experiences encouraged me to help break the stigma too. A part of me feels insecure about sharing this, but it also feels like the right thing to do.

In game theory, we often assume that people only interact in one game at a time. In a new paper, we explore theoretically and experimentally how people cooperate when they engage in two games concurrently, either with the same partner or with different partners, www.nature.com/articles/s41...
