Our results suggest that social structure—especially higher-order and overlapping interactions—is central to sustaining cooperation. This extends the evolutionary game theory toolkit for studying real group dynamics. 6/7

The outcome?. Higher cooperation levels across the board. More structural overlap → more cooperation. Coupled dynamics allow feedback across scales, enhancing coordination. 5/7

Our new model introduces:. ✅ Group-size dependent strategies. ✅ Tunable structural overlap between hyperedges. ✅ Dynamical coupling between different interaction orders. It’s a more faithful representation of real collective dynamics. 4/7

But that model had key limitations:. 🧠 Same strategy used across all group sizes. 🔗 No structural overlap between different hyperedges. Both are unrealistic for many social and biological systems. 3/7.

Group interactions—not just pairwise ones—shape how cooperation emerges in real-world social dilemmas. In earlier work, we showed higher-order games on hypergraphs can boost cooperation under the right conditions. 📄 2/7.

Understanding how cooperative behaviors can emerge from competitive interactions is an open problem in biology and social sciences. While interactions are usually modeled as pairwise networks, the...
