Taking Stock of Solidarity between People of Color: A Mini Meta-Analysis of Five Experiments

Recent work suggests that solidarity between people of color (PoC) is triggered when a minoritized ingroup believes they are discriminated similarly to another outgroup based on their alleged foreignness or inferiority. Heightened solidarity then boosts support for policies that benefit minoritized outgroups who are not one’s own. Available experiments on this pathway vary by participants (e.g., Asian, Black, Middle Eastern, and Latino adults), manipulations (similar discrimination as foreign vs. inferior ), and pro-outgroup outcomes (support for undocumented immigrants, Black Lives Matter). We report a pre-registered mini meta-analysis of this solidarity mechanism. Across five experiments ( N = 3,252), similar discrimination as foreign or inferior reliably triggers solidarity between PoC, which then substantially increases support for pro-outgroup policies. This mediated pathway is robust to possible confounding and emerges across studies and planned contrasts of them. We discuss what the viability of this mechanism implies for further theoretic and empirical innovations in a racially diversifying polity.
