The two studies reported here show that mixed-race individuals in the United States who identify as biracial or multiracial can encounter difficulty in asserting their identities, and that such constraints can lead to negative psychological consequences. In Study 1 we found that when discussing instances in which their biracial or multiracial identity caused them to feel tension, mixed-race individuals spontaneously mentioned demographic questionnaires that forced them to select only one racial group. Using this real-world experience as a model, Study 2 found that compared with those who were able to choose multiple racial groups, those who were constrained to only one racial group showed lower performance self esteem and motivation. Additionally, this constraint, even after it was removed, influenced participants’ subsequent report of their racial identities. Those who had been forced to choose only one racial group were more likely to report a discrepancy between their chosen identity and their social experience.
