Paranoia is associated with variation in social behaviour, such as lower inclination to trust others or to behave generously in economic game settings. Such variation may stem, in part, from a reduced tendency to socially identify with others, although previous studies have reported mixed results. We tested whether paranoia involves altered social identification in a pre-registered online study investigating the relationship between a measure of social identification, paranoia, and social behaviours in economic games. We successfully manipulated social identification, but paranoia was associated with slightly increased social identification overall. Neither paranoia nor social identification predicted behaviour in the economic games, and there was no interaction between paranoia and social identification regarding trusting and cooperative behaviours. Our results converge with recent work suggesting that more paranoid individuals may harbour a higher tendency to perceive themselves as having similar beliefs to others. We discuss some key areas for future research to progress understanding in this area.
偏执狂与社会行为的变化有关，比如在经济博弈情境中信任他人的倾向较低或行为不够慷慨。这种变化可能部分源于与他人进行社会认同的倾向降低，尽管此前的研究报告结果不一。我们在一项预先注册的在线研究中测试了偏执狂是否涉及社会认同的改变，该研究调查了社会认同度量、偏执狂与经济博弈中的社会行为之间的关系。我们成功操纵了社会认同，但总体而言，偏执狂与社会认同的略微增加有关。偏执狂和社会认同都无法预测经济博弈中的行为，并且在信任和合作行为方面，偏执狂与社会认同之间没有相互作用。我们的结果与最近的研究一致，表明偏执倾向较高的个体可能更倾向于认为自己与他人有相似的信念。我们讨论了一些未来研究的关键领域，以推动对该领域的理解。
