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.
