| Outline of Final Research Achievements |
A stigmatized (or discredited) person may "pass" as normal. This study explored the condition that passing is successful, by formulating an imperfect information game in which a stranger does not know whether the discreditable person is discredited or normal but knows the proportion of the stigmatized. It revealed that the "normal" type's strategy that leads to a hybrid equilibrium is important. It also examined the difference between "passing" in the game, "covering" in interactions with those who know the discreditable person's type, and "masquerading" in signaling games. In addition, it checked the validity of the theoretical findings by referring to case studies and autobiographical notes of stigmatized persons.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の主な学術的意義は、数理モデルの構築と解析によって差別・偏見の現状を理解することに貢献し、質的調査による既存の研究成果と数理モデルによる考察とを融合し、「合理性」や「均衡」などの社会科学的重要概念の再検討を行ったところにある。社会的意義としては、スティグマを付与されうる者が直面する現状の理解にもとづいて、周囲の他者の対応や制度変更等による状況改善の可能性に関して政策論的考察を行ったことが挙げられる。
