What is it about?

The emergence of large-scale cooperation remains one of the great scientific puzzles across many disciplines. Previous research has shown large-scale cooperation can be maintained through the use of reputation. However, people belong to multiple social groups with differing reputations. We model how reputation at a lower scale of cooperation (smaller group) will undermine reputation at a higher scale of cooperation (larger group).

Why is it important?

Understanding how large-scale cooperation is maintained is important for tackling global issues, such as the climate crisis. Our model shows how small-scale social groups are prioritized over their large-scale counterparts. This explains why it is so difficult to cooperate on pressing issues that effect us all.
