Replication Data for: Shared Discrimination’s Effect on Solidarity Between People of Color Is Uniform Across Major Racial, Political, and Social Differences

Solidarity between people of color (PoC) is key to understanding multiracial coalition-building in the U.S. However, limited statistical power has constrained research on whether shared discrimination’s effect on solidarity is reliably moderated by differences in race, political orientation, and social background, which structure the internal diversity of racially stigmatized subgroups within the mega-category, people of color. We report a pre-registered meta-analysis of eight published experiments (N = 5,813), which used a common design to test shared discrimination’s effects among Black Americans, Asian Americans, Latinos, and Middle Eastern and North African individuals. Despite known heterogeneity in these group’s social and political attitudes, we find that shared discrimination’s effect on solidarity is statistically uniform across race/ethnicity, partisanship, ideology, nativity, education, gender, and age. These results indicate that shared discrimination appeals broadly and reliably activate solidarity across diverse PoC subgroups, further affirming this psychological mechanism’s crucial role in fostering robust multiracial coalitions.
