Ordinance influences individuals' perceptions towards prospects of social circumstance but not the status quo: An experimental field study on sexual minorities issues in Japan. 条例は社会状況の見通しに対する個人の知覚に影響を与えるが、現状には影響を与えない：日本における性的マイノリティ問題に関する実験的フィールドスタディ Asian Journal of Social Psychology. https://doi.org/10.1111/ajsp.12568
Scientific evidence shows that institutional decisions can change individuals’ private attitudes towards relevant issues. However, little is known about their effect on individuals’ perceptions of social norms. This intriguing question has gained the attention of scholars. Nonetheless, the findings are primarily observed only in samples of the Western, Educated, Industrialised, Rich, and Democratic countries, leading to doubts about their generalisability. This study experimentally tested residents’ (N = 411) reactions to the new Tokyo ordinance prohibiting discrimination against sexual minorities enacted on October 5, 2018, and tested whether it dispelled self–other discrepancies regarding tolerance towards sexual minorities (i.e., pluralistic ignorance). The results showed that exposure to information about enactment increased future perceptions of support and understanding of sexual minorities. By contrast, private attitudes, perceptions of current social norms, and willingness to speak out did not change. Willingness to speak out was indirectly enhanced through increased perceptions of gaining future support. Furthermore, Tokyo residents overestimated other residents’ negative attitudes towards sexual minorities. However, even when informed of the new ordinance, this self–other discrepancy in intolerance towards sexual minorities was not corrected. These findings suggest that institutional decisions can shape the perception of social norm change in the future beyond Western countries.
