This set of two studies employed the integrated threat theory to examine attitudes toward affirmative action (AA). The first study found that opposition to the policy of AA was predicted by realistic threats, symbolic threats, and personal relevance; while attitudes toward the beneficiaries of AA were predicted by three of the four threat variables (symbolic threats, intergroup anxiety, and negative stereotypes), and in-group identity. The second study replicated and expanded on the first study and found that the effects of several individual-difference variables (racism, antiBlack affect, and political conservatism) on opposition to AA were mediated by three of the threats in the integrated threat theory (realistic threats, symbolic threats, and negative stereotypes). The implications of the results are discussed.For over 30 years, affirmative action has been one of the most controversial social policies of our times. Opponents question whether or not affirmative action is needed or necessary and whether it violates the norm of meritocracy (fairness) that is so dear to many Americans. Many opponents view affirmative action as offering preferential treatment to its beneficiaries while creating reverse discrimination for nonbeneficiaries of affirmative action. Proponents, on the other hand, suggest that affirmative action assists the achievement of women and minorities, and provides female and minority role models. Proponents also view affirmative action as helping to remedy past discriminatory practices, offsetting current discrimination, and increasing diversity in the workplace.Overall, Americans tend to support the idea of equal opportunity, yet there is widespread opposition to affirmative action (Kinder & Sanders, 1 The authors thank Cookie Stephan for her comments on an earlier version of this manuscript; Larry Gregory and Douglas Gillan for serving as statistical consultants; and the anonymous reviewers for their helpful comments.
