Contemporary prejudice research focuses primarily on people who are motivated to respond without prejudice and the ways in which unintentional bias can cause these people to act inconsistent with this motivation. However, some real-world phenomena (e.g., hate speech, hate crimes) and experimental findings (e.g., Plant & Devine, 2001; suggest that some expressions of prejudice are intentional. These phenomena and findings are difficult to explain solely from the motivations to respond without prejudice. We argue that some people are motivated to express prejudice, and we develop the motivation to express prejudice (MP) scale to measure this motivation. In seven studies involving more than 6,000 participants, we demonstrate that, across scale versions targeted at Black people and gay men, the MP scale has good reliability and convergent, discriminant, and predictive validity. In normative climates that prohibit prejudice, the internal and external motivations to express prejudice are functionally nonindependent, but they become more independent when normative climates permit more prejudice toward a target group. People high in the motivation to express prejudice are relatively likely to resist pressure to support programs promoting intergroup contact and vote for political candidates who support oppressive policies. The motivation to express prejudice predicted these outcomes even when controlling for attitudes and the motivations to respond without prejudice. This work encourages contemporary prejudice researchers to broaden the range of samples, target groups, and phenomena that they study, and more generally to consider the intentional aspects of negative intergroup behavior.Over the past two decades, researchers interested in prejudice and stereotyping have focused intensely on people's motivations to respond without prejudice. This focus was spurred by the desire to understand a particular paradox: despite apparent nation-wide improvements in racial attitudes in the United States since the onset of the Civil Rights Movement (Schuman, Steeh, Bobo, & Krysan, 1997), pervasive disparities persist between White people and minority group members (e.g., Bertrand & Mullainathan, 2004;Bradford, Newkirk, & Holden, 2009;Steele, 1997). This societal paradox mirrors a personal paradox: even people whose beliefs are inconsistent with prejudice sometimes exhibit subtly biased behaviors towards outgroup members (e.g., McConnell & Leibold, 2001). Although these behaviors do not clearly reflect negative intentions, they nonetheless can have negative consequences for out-group members (Crosby, Bromley, & Saxe, 1980;Devine, 1989 Zuwerink, & Elliot, 1991). Thus, researchers have reasoned that one route to understanding the causes of lingering disparities is to understand how and why people act in ways that belie their intentions (e.g., Devine, Forscher, Austin, & Cox, 2012;Fiske, 1998).The prevailing focus on the motivation to respond without prejudice and its relationship to unintentional discrimination contrasts with th...
