Erratum: Ethnic change, personality, and polarization over immigration in the American public (Public Opinion Quarterly (2020) DOI: 10.1093/poq/nfv022)
In Johnston, Newman and Velez (2015), we examine how personality traits related to uncertainty aversion moderate the effect of local ethnic change on perceived cultural threat from immigrants and on immigration-related policy preferences. In two studies-one observational and one experimental-we find that ethnic change increases perceptions of threat and decreases support for immigration among uncertainty-averse citizens but has the opposite effect for the uncertainty tolerant. Neither study finds evidence for similar associations with levels of ethnic diversity. The experimental analyses reported in the original published paper draw on three waves of data collected from Amazon Mechanical Turk and erroneously include responses from workers who participated in the study more than once. In this erratum, we report results from identical models with a corrected dataset that excludes repeat survey takers. The primary conclusion of the study-that ethnic change polarizes immigration opinion by citizen personality-is not affected by this error. However, the corrected results suggest that a randomly assigned experimental treatment containing only ethnic cues-that is, without information about changes in ethnic composition-may also induce personality-based polarization of immigration attitudes relative to a control condition. We discuss possible interpretations of this result.
