Racial conflict between African Americans and Whites has been observed to occur most frequently at two critical points: when African Americans make up approximately 30% of a given group or when African Americans make up approximately 50% of a given group. These two critical ratios are referred to as the J and (inverted) U patterns of racial conflict, respectively. To date, most of the data supporting either the J or U models have been derived from large demographic studies that do not directly assess individual perceptions. Thus, little is known about the individual reactions of members from either racial group to varying percentages of group racial composition. This small-group experiment examined the responses of African-American and White subjects to their inclusion in four-person groups of varying racial compositions. Three racial configurations were created and included the following percentages of African Americans: 25%, 50%, and 75%. The results support the U model of racial conflict. Moreover, the U model fit the data equally well for African Americans and Whites.
