Understanding the social dynamics that cause cooperation to thrive, or fail

Many examples of cooperation exist in nature, but it’s far from a universal characteristic of human or animal groups. Using a mathematical model, Erol Akçay showed that less randomly connected social networks make cooperation more likely, but those dynamics may ultimately lead to cooperation’s collapse.
