Outline of Final Research Achievements

First, we demonstrated that the finding from previous research -that people are more likely to judge racially ambiguous individuals as out-group members when they perceive resource scarcity- is not replicated (at least in contemporary Japan). Second, we showed that the model suggesting resource scarcity promotes out-group exclusion or un-inclusion via increased zero-sum beliefs receives variable support depending on the research method used, such as vignette experiments, priming experiments, and secondary analysis of large-scale social surveys.

Academic Significance and Societal Importance of the Research Achievements

上述した1つ目の成果は、資源不足による内集団の狭隘化が態度や行動より前の「知覚」という段階において「非意識的に」生じうるという、理論的・社会的インパクトのある知見に疑問を呈するものである。2つ目の成果は、資源不足が外集団成員排斥意図に及ぼす影響およびそのプロセスについての理解を深めるものであるとともに、今後、資源不足の影響を明らかにしようとする際に用いるべき研究方法についてのヒントとなるものである。
