Intelligence, Personality, and Gains from Cooperation in Repeated Interactions
通过实验研究智力与人格特质如何影响重复博弈中的合作行为，发现智力对长期合作有显著正向作用，而尽责性和宜人性仅产生暂时性影响。
We study how intelligence and personality affect the outcomes of groups, focusing on repeated interactions that provide the opportunity for profitable cooperation. Our experimental method creates two groups of subjects who have different levels of certain traits, such as higher or lower levels of Intelligence, Conscientiousness, and Agreeableness, but who are very similar otherwise. Intelligence has a large and positive long-run effect on cooperative behavior. The effect is strong when at the equilibrium of the repeated game there is a trade-off between short-run gains and long-run losses. Conscientiousness and Agreeableness have a natural, significant but transitory effect on cooperation rates.
