What is it about?
Our study integrates evolutionary game theory with opinion dynamics to see how this "peer exchange" affects cooperation. Consensus is Key: When populations reach a consensus on risk (even from polarized starting points), cooperation significantly increases.

Why is it important?
The Journey Matters: Even if populations end up with similar average views, the way those opinions transitioned determines if the group succeeds or fails. Communication as a Tool: Peer opinion exchange acts as a powerful mechanism to avoid collective failure.
Perspectives
In real-world crises—from climate change to public health—risk isn’t just a static number; it’s a perception that evolves as we talk to one another.
