Objectives: This study investigates how racial identity and phenotypicality (i.e., racial ambiguity) shape the perception of biracial individuals in both White and Black perceivers. We investigated complex racial categorization and its downstream consequences, such as perceptions of discrimination. Method: We manipulated racial phenotypicality (Black or racially ambiguous) and racial identity (Black or biracial) to test these cues' influence on Black and White race categorizations in a sample of both White (n = 145) and Black (n = 152) identified individuals. Results: Though racial identity and phenotypicality information influenced deliberate racial categorization, White and Black participants used the cues in different ways. For White perceivers, racial identity and phenotypicality additively influenced Black categorization. For Black perceivers, however, racial identity was only used in Black categorization when racial ambiguity was high. Perceived discrimination was related to White (but not Black) perceivers' distribution of minority resources to targets, however Black categorization related to perceived discrimination for Black perceivers only. Conclusion: By demonstrating how Black and White individuals use identity and phenotype information in race perceptions, we provide a more complete view of the complexities of racial categorization and its downstream consequences.
