The article explores how repeated interactions between people can lead to cooperation. By introducing ambiguity in decision-making, players can use silence as a powerful strategy. This means that in a repeated game, the specific rules for enforcing cooperation are not as important as the overall goal. Adding a small amount of uncertainty can actually encourage cooperation among players. The research shows that cooperation can emerge without changing the information available to players or assuming they always make rational choices. The study also provides a comprehensive understanding of the outcomes possible in repeated games.
