Feeling correct is feeling prejudiced: The differential effects of attitude correctness and attitude clarity on evaluations of outgroups

Global attitude certainty consists of two subconstructs: attitude clarity—certainty that one is aware of one’s true attitudes—and attitude correctness, certainty that one’s attitudes are morally correct and valid. Attitude correctness is more often associated with group-related psychological and behavioral outcomes than attitude clarity. As such, we expected that attitude correctness, but not attitude clarity, would be associated with more negative attitudes toward outgroups when group boundaries are defined by attitudes. Across four studies, greater attitude correctness related to more negative attitudes toward attitudinal outgroups regardless of context (e.g., political, religious); attitude clarity’s relationship to prejudice was inconsistent (Studies 1a and 2: positive or no relationship; Study 3: negative; Studies 1b and 4: no relationship). In Studies 2 and 3, mediational analyses showed that greater attitude correctness was associated with stronger beliefs that group boundaries are sharp and distinct (i.e., discreteness beliefs), which in turn was associated with greater prejudice. Finally, Study 4 demonstrated that the attitude correctness–prejudice link was associated with greater intention to engage in competitive behaviors in a conflict resolution scenario with an outgroup member.
