This study investigated the effects of participants’ sex and the facial trustworthiness of proposers on third‐party decision‐making. Sixty‐three participants participated in this study. The participant's task was to act as an interest‐free third party who observed a dictator game in which proposers with either trustworthy or untrustworthy faces made offers to recipients, to evaluate the reasonableness of the offers, and to express their intentions to punish the proposers. The results showed that offers from trustworthy proposers were rated as more reasonable than offers from untrustworthy proposers. Similarly, the participants were more likely to punish untrustworthy proposers than trustworthy proposers. In addition, there was a trend that male participants punished proposers more severely than female participants when proposers made unfair offers. These results demonstrate that an individual's facial trustworthiness affects other people's judgment and decisions.

参与者的性别和提议者的面部信任度对独裁者游戏中第三方决策的影响。

这项研究调查了参与者的性别和提议者的面部信任度对第三方决策的影响。六十三名参与者参加了这项研究。参与者的任务是扮演无利益的第三方，观察独裁者游戏，在该游戏中，具有可信赖或不可信面孔的提议者向接收者提出要约，评估要约的合理性，并表达其惩罚提议者的意图。结果表明，值得信赖的提议者的报价比不值得信赖的提议者的报价更为合理。同样，与可信赖的提议者相比，参与者更可能惩罚不可信赖的提议者。此外，当提议者提出不公平的要约时，男性参与者对提议者的惩罚比女性参与者要严厉。这些结果表明，一个人的面部信任度会影响其他人的判断和决定。
