It’s Personal: The Big Five Personality Traits and Negative Partisan Affect in Polarized U.S. Politics. Steven W. Webster. American Behavioral Scientist, http://journals.sagepub.com/doi/abs/10.1177/0002764218756925?journalCode=absb

Abstract: One of the most important developments within the American electorate in recent years has been the rise of affective polarization. Whether this is due to notions of group-based conflict or ideological disagreement, Americans increasingly dislike the opposing political party and its supporters. I contribute to this growing literature on affective polarization by showing how differences in individuals’ Big Five personality traits are predictive of both whether an individual dislikes the opposing party and the degree to which they express this hostility. Modeling negative affect toward the opposing party as a two-stage process, I find that Extraverted individuals are less likely to have negative affective evaluations of the opposing party. Additionally, conditional on disliking the opposing party, my results indicate that higher levels of Agreeableness lowers the degree to which individuals dislike the out-party. Moreover, these relationships are substantively stronger than common sociodemographic predictors such as age, race, and educational attainment.
