(Please Don't) Say It to My Face! The Interaction of Feedback and Distance: Experiments with Vulgar Language
在实验室和在线最后通牒博弈中引入接收者的单向无限制反馈（粗俗语言），发现负面反馈针对低出价、正面反馈针对高出价，且实验室中反馈显著提高了提议者的出价金额，但在线实验中无此效果，表明社会距离或物理距离增加会削弱非货币惩罚的有效性。
Summary I extend current understanding of non‐monetary punishments by introducing one‐way unrestricted feedback (vulgar language) from responders in laboratory and online ultimatum games. Feedback changes in the expected direction. Negative feedback is returned in the event of low offers while higher offers receive positive feedback. Additionally, the possibility of unrestricted feedback significantly increases amounts sent by proposers, but only in the lab. This effect is statistically significant and large in magnitude but is not present in the online experiments. These results illustrate that increases in social distance and/or physical proximity can weaken the effectiveness of non‐monetary punishments.
