What they think of us: Meta-beliefs and solidarity-based collective action among the advantaged

Collective action researchers have recently started investigating solidarity-based collective action by advantaged groups. This literature, however, has overlooked intergroup meta-beliefs (MBs, i.e., beliefs about the outgroup's beliefs), which we argue are crucial, since solidarity inherently involves protesting for the outgroup. In the context of racial inequality in the U.S., we focused on three MBs White Americans could hold: responsibility, inactivity, and allyship. In two studies (Ntotal = 648), we found that inactive and responsible MBs predicted higher collective action tendencies among low White identifiers via guilt and obligation to act. Conversely, we found that both predicted lower collective action tendencies among high White identifiers, via perceived unfairness. Finally, we found that ally MB was positively associated with collective action tendencies, regardless of identification. We highlight the importance of the meta-perspective in understanding solidarity-based collective action, and discuss conceptual and practical implications of these findings.
