Compares three models positing differing roles for values in predicting fairness judgments and support of affirmative action: Tetlock's (1986) value pluralism models, Lind's (1992) fairness heuristic hypothesis, and Jackman's (1978) model involving no role for values. Results support the fairness heuristic hypothesis, indicating that values play a significant role in determining support for affirmative action. (GR)
