Cooperation under oath: A case for context-dependent preferences
研究宣誓如何影响囚徒困境中的行为，发现宣誓使后行动者从自私转向条件合作，支持偏好随宣誓情境变化的假说。
The oath has been shown to improve behavior toward social objectives. Existing research suggests that the oath promotes pro-social behavior without affecting an underlying preference for cooperation. We examine whether an oath impacts behavior in the simultaneous and sequential versions of the prisoners’ dilemma and explore whether that impact could be attributed to a change of preference for the cooperative outcome. We observe an overwhelming transfer of reported strategies by oath-takers moving second from selfish (always defect) to conditionally cooperative (cooperate against cooperation by first movers). Our results lend support to the hypothesis that preferences depend on the oath-taking context.
