Outline of Final Research Achievements

An evolutionary simulation model focusing on sociality, where altruism can affect human risk perception, was constructed to identify what factors affect extreme risk perception, and what interventions can moderate the extreme response. The model suggested that extreme risk aversion tend to be moderated when they receive support from their relatives. Utilizing this insight, messages highlighting support from relatives were designed. The intervention effect was investigated by internet questionnaire surveys in the real world, where the messages increased sense of familial support and moderated extreme risk aversion.

Academic Significance and Societal Importance of the Research Achievements

進化の観点に基づく定量的な分析により、自己利益最大化とは異なるリスク認知が発生することをシミュレーションによって示し、人間の社会性の進化に由来するリスク認知の発生機構を解明した。また、このシミュレーションから、リスク認知に影響する特性を抽出し、これを活用した情報提供によって、実際に現実世界において極端なリスク認知の緩和が可能であることを示した。これにより、設計指針が確立されていなかった行動変容方策としての「ナッジ」の設計指針に対して、体系的で効率的な設計の枠組みを提示した。
