Komiya, A.（小宮あすか）, & Mifune, N.（三船恒裕） (2015). An individual difference in betrayal aversion: Prosociality predicts more risky choices in social but not natural domains. 裏切り回避傾向の個人差：向社会性は社会的なリスク選択をしやすくさせる Letters on Evolutionary Behavioral Science, 6(1), 5-8. doi: 10.5178/lebs.2015.33
The present study investigated the relationship between betrayal aversion, i.e., the tendency to avoid specifically social risks (and not non-social, or “natural” risks), and social value orientation using economic games. Participants engaged in the Faith Game, which requires social trust, and a standard gambling game. Individuals denoted as “proself” were less likely to choose the risky option during the Faith Game as compared to individuals noted as “prosocial”; there was no difference between the groups during the gambling game. We discuss these results in terms of individual differences in betrayal aversion.
