The Effect of Group Identity on Perceptions of Bias and Willingness to Protest: Group Identity and LGBTQ+ Microaggression

With increasing social diversity, subtle forms of discrimination, referred to as microaggression, have pervaded. By conducting an experiment, the present research identifies the effect of group identity (common identity, emphasizing similarities between groups vs dual identity, emphasizing a distinct subgroup within a superordinate group) on heterosexuals’ perceptions of bias against sexual minorities and willingness to protest on their behalf. Specifically, the study focuses on gay men as a target of subtle discrimination. Participants (N = 49)—Korean heterosexuals in their 20s—were randomly allocated to the common identity, dual identity, and control condition. We found that group identity had a significant effect on perceptions of bias and a marginally significant effect on willingness to protest. Specifically, dual identity, compared to common identity, marginally heightened perceptions of bias and willingness to protest. Theoretical and practical implications are discussed regarding the effect of group identity representation on intergroup relationships in the Korean context.
