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 conducted by Livingstone, Fernández Rodríguez, and Rothers (2019) 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 the findings in the relations of Japanese and Chinese residents in Japan. As expected, felt understanding uniquely predicted intergroup relational outcomes (e.g., outgroup belief, action tendencies, and evaluation of ingroup-outgroup relations) in the relations. The authors’ findings have important implications for helping us improve the relations of Japanese and Chinese residents in Japan.
