Confederate monuments have long been common in the U.S. but recent events have brought the debate over whether they represent Southern pride or racial animosity into the mainstream. In two experiments, we show that presenting information about changing racial demographics in the United States affects perceived group status threat in White Americans, and that group status threat relates to support for Confederate monuments. Specifically, we find evidence of moderation of threat by political orientation, such that more conservative participants showed an increase in group status threat when exposed to information about shifting demographics, while more liberal participants showed a decrease. Regardless of political identification, greater perceived group status threat was associated with more support for keeping current Confederate monuments on display in public areas and less support for adding contextual information or comparable monuments of abolitionists. These results suggest that support for these types of symbols is related to anxiety about changing racial demographics, but that White liberals and conservatives may be interpreting these demographic changes differently.
