Members of disadvantaged groups sometimes support societal systems that enable the very inequalities that disadvantaged them. Is it possible to explain this puzzling system-justifying orientation in terms of rational group-interested motives, without recourse to a separate system motive? The social identity model of system attitudes (SIMSA) claims that it is. SIMSA proposes that the system justification shown by a disadvantaged group (e.g., African American women) can sometimes support identity needs that are tied to a more inclusive (superordinate) in-group (e.g., Americans). There is already some supportive evidence for this proposition, but it is not yet clear whether: (1) such trends are visible in a wider range of disadvantaged contexts, and (2) this explanation also applies to those who are strongly invested in their subgroup (e.g., feminists). In two waves of a large nationally representative survey from 21 to 23 European states (Ntotal = 84,572) and two controlled experiments (Ntotal = 290 women), we found that: (a) system justification was positively associated with superordinate ingroup identification across multiple cases of disadvantage (Studies 1-3), (b) system justification increased when this inclusive identity was made more salient (Studies 2 & 3), and (c) system justification was visible even amongst feminists when they activated their superordinate (Italian) identity (Study 3).
