The outcomes of 2 experiments investigating the effectiveness of advertisements that use (non)traditional stereotypes of women (Experiment 1) or men (Experiment 2) are reported. Effectiveness of the ads was tested in relation to perceivers' attitudes toward female or male gender roles, respectively. The main finding was that for both male and female versions of the advertisements, the paternalistic ad strategies were more effective than were the envious ones, supporting the predictions of the stereotype content model over the classic prediction of negative effects of nontraditional gender portrayals for advertising effectiveness. Moreover, attitudes toward gender roles played only a limited role in determining ad effectiveness. Theoretical and practical implications are discussed.
