Racial conflict between African Americans and Whites has been observed
to occur most frequently at two critical points: when African America
ns make up approximately 30% of a given group or when African American
s make up approximately 50% of a given group. These two critical ratio
s are referred to as the J and (inverted) U patterns of racial conflic
t, 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 th
e individual reactions of members from either racial group to varying
percentages of group racial composition. This small-group experiment e
xamined 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 percenta
ges 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.
