Individuals often cannot address (objective) group injustices until they develop a (subjective) critical awareness of them. In three studies, we tested two potential psychological pathways toward critical awareness: Reflection (deductive, knowledge driven) and action (inductive, action driven) mindsets. Across studies, participants were exposed to an objectively unjust event, enacted by the experimenter. Based on a pilot study (N = 31) and first experiment (N = 28), we developed the hypothesis that action (vs. reflection) mindsets increase group entitativity (due to their reliance on expectancy effects), but not necessarily (subjective) critical awareness of (objective) group injustice. Study 2 (N = 121) confirmed this hypothesis. We discuss the difficulties of developing (subjective) critical awareness of (objective) group injustices.
