A Social Psychological Study of the Cognition of Opinion Distributions among In-Group and Out-Group Members -An Examination of the Processes Underpinning Intergroup Conflict.

1.本研究揭示了共识估计中的组内投射效应可以发生在非二分潜变量方面。本研究还发现，内群体投射效应受认知一致性动机和自我群体认同两个因素的影响。研究结果与社会认同理论的解释一致。4.一项研究还揭示了自我位置判断与一致性估计之间的因果关系。研究表明，对一致性的估计本身会增强对自我位置的意识，而自我位置是投射而不是注入的。5.关于外群体同质性效应的研究和关于刻板印象作为协变判断的实验研究表明，社会分配的研究为减少群体间冲突提供了重要的启示。

1.The present study revealed that the in-group projection effect in consensus estimation can take place with regard to non-dichotomous latent variables. Overestimation of the prevalence was observed for an opinion position consistent with one's own attitudes.2.The study also revealed that the in-group projection effect is mediated both by (1) the motivation for cognitive consistency and by (2) the self-group identification.3.Another series of studies demonstrated that the projection effect increases when the boundary between the in- and out-group is salient. The results were consistent with the interpretation based on Social identity Theory.4.One study also revealed a causal relationship between judgments of the self-position and consensus estimates. The study demonstrated that the estimation of consensus by itself enhances the awareness of the self-position which is in turn projected rather than injected.5.Investigations regarding the out-group homogeneity effect and an experimental study on stereotyping as covariational judgments indicated that the study of social distribution provides significant implications regarding the ways to reduce intergroup conflict.
