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; 2009) 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 non-independent, 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.
