When a person's language appears to be political-such as being politically correct or incorrect-it can influence fundamental impressions of him or her. Political correctness is "using language or behavior to seem sensitive to others' feelings, especially those others who seem socially disadvantaged." One pilot study, 6 experiments, and 3 supplemental experiments (N ϭ 4,956) demonstrate that being politically incorrect makes communicators appear more authentic-specifically, less susceptible to external influence-albeit also less warm. These effects, however, are moderated by perceivers' political ideology and how sympathetic perceivers feel toward the target group being labeled politically correctly. In Experiments 1, 2, and 3 using politically incorrect language (e.g., calling undocumented immigrants illegals) made a communicator appear particularly authentic among conservative perceivers but particularly cold among liberal perceivers. However, in Experiment 4 these effects reversed when conservatives felt sympathetic toward the group that was being labeled politically correctly or incorrectly (e.g., calling poor Whites white trash). Experiment 5 tests why political incorrectness can boost authenticity, demonstrating that it makes communicators seem less strategic. Finally, Experiment 6 examines the use of political language in a meaningful field context: perceived persuasion in real political debates. Debaters instructed to be politically correct (vs. politically incorrect) were judged by their uninstructed conversation partners to be easier to persuade during the conversation, although they actually reported being similarly persuaded. Together, these findings demonstrate when and how using politically incorrect language can enhance a person's authenticity.
