Some background: The literature on indirect reciprocity describes how people act when their reputation is at stake. It asks which social norms support cooperation, and which norms are stable (such that people have an incentive to follow them).

chilbe.bsky.social•97 days ago

Unfortunately, results in this literature often depend on subtle details. In particular, the stability of a norm typically depends on the precise structure of social interactions (how observable individual actions are, or to which extent people engage in gossip).

Even if a given social norm is successful in one scenario, it might be unstable in another. In our paper, we try to organize these different findings by looking at a key variable: the extent to which individual opinions about others turn out to be correlated (synchronized).

These correlations depend on the structure of social interactions, but also on the social norm in place. We find that a norm can only sustain cooperation if the resulting opinions of different community members become sufficiently correlated.

Opinions tend to become strongly correlated, for example, when social interactions are widely observable. Alternatively, they become correlated when individuals use gossip to synchronize their views. Here is an open version of the paper: https://arxiv.org/abs/2409.05551

It sounds similar to advanced Game theory of social probability? How fascinating! 🧐😃
