Accuracy was dropped from prejudice definitions in favor of pure negative attitude

Evidence

Although antipathy became an enduring (if problematic) fixture of definitions of prejudice subsequent to Allport’s book, many theorists dropped the requirement that the beliefs about target groups are necessarily inaccurate, paralleling the removal of inaccuracy from most definitions of stereotype (see Ashmore & Del Boca, 1981). The resulting minimalist definition of prejudice as an overall negative attitude toward a group then became widely accepted in social psychology (e.g., Esses, Haddock, & Zanna, 1993). Removal of the accuracy criterion from the definition of prejudice opened the way to a more sophisticated analysis of accuracy and inaccuracy in stereotyping and prejudice (Judd & Park, ch. 8 this volume). — John F.
