The current study aims to explore the influence of social comparison on risk decision-making for self and for groups in intergroup contexts.
Two experiments with the within-subjects design of 2 (social comparison: upward comparison, downward comparison) × 3 (decision-maker role: for "me", for "us", for "them") were conducted in this study. Experiment 1 focused on the ingroup contexts, and experiment 2 focused on the outgroup contexts.
(1) in outgroup contexts, individuals are more risk-seeking in upward comparison conditions than in downward comparison conditions. However, the difference disappears in ingroup contexts. (2) Making decisions for "them" is riskier than making decisions for "me" and for "us" with no significant differences between the latter two and consistent across intergroup contexts. (3) The difference in risk decisions made amid upward and downward comparisons is amplified for decisions made for groups.
The findings may support the selective accessibility model and provide an interpretation with responsibility alleviation for self-group differences in risk decision-making.
本研究旨在探讨社会比较对群体间情境下自我和群体风险决策的影响。
本研究进行了两项实验，采用2（社会比较：向上比较、向下比较）×3（决策者角色：为“我”、为“我们”、为“他们”）的被试内设计。实验1聚焦于内群体情境，实验2聚焦于外群体情境。
（1）在外群体情境中，个体在向上比较条件下比在向下比较条件下更倾向于冒险。然而，在内群体情境中这种差异消失。（2）为“他们”做决策比为“我”和“我们”做决策风险更大，后两者之间无显著差异且在群体间情境中一致。（3）向上和向下比较中风险决策的差异在为群体做决策时被放大。
研究结果可能支持选择性通达模型，并为群体间风险决策中的自我群体差异提供责任减轻的解释。
