Political plausible deniability: Political difference can divert attributions of socially unacceptable bias

While many social biases are considered taboo, bias against political outgroups is increasingly explicit, ubiquitous, and tolerated. We contend that expressing political bias can reduce third-party perceptions of socially unacceptable biases-a phenomenon we call political plausible deniability. By diverting attributions away from biases based on race, gender, or sexual orientation, individuals can express bias yet ostensibly align with social norms. Pretests indicate people intuitively understand the concept of a socially acceptable bias, with political bias rated most acceptable among 15 biases. Across 13 preregistered survey experiments, we find that third parties are less likely to perceive racism, sexism, and (sometimes) heterosexism when an actor expresses an antiliberal statement toward a Black, female, or gay target. These effects emerge across open-ended (Studies 1a-c) and Likert-type (Studies 2a-c, 3a-c, 4a-c) responses, which we replicate in a conjoint experiment (Study 5). Participants' political leanings did not moderate effects. Finally, in 12 exploratory studies, we further illuminate political plausible deniability, for example, by examining anticonservative biases, comparing political with other (nonpolitical) biases, and exploring the role of intersecting target identities. Our research exposes an inconspicuous way that political bias may shape social perception, with implications for understanding how prejudice operates in everyday life.
