Relating pattern deviancy aversion to stigma and prejudice

What predicts people’s powerful and universal dislike of social deviancy? Across six studies, aversion towards non-social pattern deviancy, for example, a row of triangles with one triangle out of line, predicted aversion towards stigmatized individuals, social norm breakers, statistically negative and positive deviants, and a racial minority group (Black individuals). The relationship between pattern deviancy and social deviancy aversion emerged across explicit and implicit measures, across cultures (United States and China), and was of a moderately large magnitude (meta-analytic effect size: d = 0.68). Studies 7 and 8 examined developmental differences. Older but not younger children’s pattern deviancy aversion related to their dislike of social norm breakers. Although non-social pattern deviancy and social deviancy judgements may seem distinct given their differing domains, people’s aversion towards non-social pattern deviancy and social deviancy consistently overlapped. These findings raise the possibility that pattern deviancy aversion plays an important role in stigmatization and prejudice. Across multiple studies, Gollwitzer and colleagues show that people's aversion towards non-social pattern deviancy and social deviancy overlap.
