  • Further Evidence for the Role of Felt Understanding in Intergroup Relations: Japanese and Chinese Relations in Japan 1

    Open Access•Tomohiro Ioku, Eiichiro Watamura•ARTICLE•Japanese Psychological Research•2025

    Felt understanding in intergroup context is the belief that members of an outgroup understand and accept ingroup members' perspectives. A series of studies in Europe recently conducted by Andrew Livingstone and colleagues showed the unique effect of felt understanding in intergroup relations. The effects were apparent even when controlling for outgroup beliefs and metabeliefs. The present article reports a cross‐cultural replication of those find…

Using a publicly available dataset with responses from approximately 300 individuals in each society, this study explores how punitive attitudes vary across r…

    As artificial intelligence (AI) becomes more integrated into society, concerns have arisen about unintended biases in AI-driven decision-making and the environmental impact of AI technology development. AI assistants such as Siri and Alexa, while helpful, can obscure decision-making and contribute to increased energy use and CO2 emissions. The present study explores whether consumers prioritize transparency and environmental sustainability over p…
