康德道德與社會偏好在類聚效應下對合作行為的影響

Abstract

我們透過線上實驗探討了康德道德與合作行為在以下三種不同賽局情境下的關係：非同步囚徒困境、信任賽局和最後通牒賽局。我們旨在探討以下問題：與具有相似背景的參與者配對會如何影響人們合作行為、親社會行為、信念和康德道德。在我們的實驗中，參與者會被隨機分配到對照組和實驗組。在對照組中，參與者會隨機與其他參與者配對；而在實驗組中，參與者只會與具有相似特徵背景的其他參與者進行配對。我們使用的分類特徵為年級、學院、感到親近的城市和讀書習慣。結果表明，與對照組相比，實驗組組更加合作，並且親社會受試者的比例更高。我們發現這些差異多來自於兩組對於報酬領先的厭惡。這項研究為我們揭示了推動合作行為的潛在機制，並增進了我們對人類社會行為的理解。

This online experiment investigates the relationship between Kantian morality and cooperation behavior in the context of three different games: sequential prisoner’s dilemma, trust game, and ultimatum game. We aim to answer the question of how pairing participants with similar backgrounds affects cooperation behavior, pro-social behavior, beliefs, and moral values. Participants were randomly assigned to a control or treatment group. In the control group, participants were paired randomly, while in the treatment group, participants were paired with individuals who shared similar background characteristics, such as grades, college, homely city, and study habits. Our findings reveal that assortative matching groups exhibit higher levels of cooperation and a greater proportion of pro-social individuals compared to random matching groups. Notably, most of these differences can be attributed to the two groups' aversion to leading payoffs. This study provides valuable insights into the underlying mechanisms that drive cooperative behavior and informs our understanding of human social behavior.
