AI Article Synopsis
- The study explores how ecological dynamics affect evolutionary games, specifically introducing death (both natural and unnatural) into the spatial prisoner's dilemma.
- This framework helps explain why cooperation is common in both animal and human societies.
- Findings indicate that people are more likely to cooperate in competitive settings and when the incentive to betray is low.
Article Abstract
By incorporating ecological dynamics into evolutionary games, we introduce natural and unnatural death to the spatial prisoner's dilemma game in which individuals can play mixed strategies. This introduction can give a simple explanation for the emergence and abundance of cooperation in animal and human societies. We found that individuals are more likely to cooperate in a highly competitive environment. In addition, our simulation results suggest that the individuals would tend to cooperate when the temptation to defect is small.
