Much of the current psychological literature investigates single category dimensions (i.e., race or social class), with little focus on the intersection of multiple social category dimensions. Yet some evidence suggests that the intersection of race and social class information influences (a) stereotype expression, (b) categorization, (c) impressions, (d) prejudice, and (e) discrimination, revealing common links between Blackness and low social class and Whiteness and high social class in at least the United States. The present article reviews evidence for considering both target race and social class as intersecting social categories that simultaneously influence intergroup processes. This analysis suggests that a more comprehensive understanding of intergroup processes can be achieved when considering the intersection of race and social class information. This review also provides a series of future directions to advance intergroup processes research.
