This chapter first reviews general conceptual and methodological issues in the study of the (in)accuracy of stereotypes. First, the authors define stereotype accuracy. Second, different types of accuracy are discussed and standards for considering a stereotype belief accurate or inaccurate are presented. Finally, the chapter reviews the empirical evidence produced thus far that bears on the (in)accuracy of stereotypes regarding personality. The strongest evidence regarding the (in)accuracy of stereotypes regarding personality have focused on gender, age, and national character stereotypes. Weaker evidence relying primarily on self-reports of individual differences with respect to racial stereotypes and miscellaneous stereotypes (e.g., jazz vs. ballet dancers) is also reviewed. The chapter concludes by developing hypotheses that could help explain the pattern of (in)accuracy in stereotypes regarding personality.
