(Purpose) The purpose of this study is to analyze the impact of social dominance tendencies and stereotypes on multicultural acceptance, and to verify the mediating effect of stereotypes on the impact of social dominance tendencies on multicultural acceptance. In addition, the purpose of this study is to verify the moderating effects of immigrant contact experience, multicultural-related mass media experience, and multicultural education experience in the relationship between social dominance tendencies and stereotypes, and to suggest policy implications based on this. (Research methods) For this purpose, a survey was conducted on 248 adults living in Seoul in 2022, and the survey data was subjected to regression analysis, SPSS Macro, and boosttrapping using the SPSS 25.0 program. (Findings) The research results are as follows. First, age, social dominance, and stereotypes were found to affect multicultural acceptance. Second, stereotypes were found to mediate the relationship between social dominance tendency and multicultural acceptance. Second, only multicultural-related mass media experience moderated the relationship between social dominance tendencies and stereotypes, and appeared to have an effect on multicultural acceptance. In other words, social dominance tendency had a negative effect on multicultural acceptance through stereotypes, and multicultural contact experience through media appeared to regulate social dominance tendency and stereotypes. (Conclusion and recommendations) First, when producing multicultural content, it is necessary to check in advance for patronizing and hateful depictions of immigrants. Second, it is proposed that multicultural society experts be used to provide multicultural understanding and human rights-related education as statutory education.
