The personalities of Danish MPs: Trait- and aspect-level differences.

Abstract

We study personality traits of Danish parliamentarians (MPs) and examine elite-voter congruence and elite differentiation. Whereas previous political elite studies have focused only on the Big Five level, we include aspect-level differences. In a highly representative survey of Danish MPs (N = 81; response rate = 46.3%) and a representative study of Danish voters (N = 3,612), we used the 60-item NEO-PI-R short version to examine personality differences on the Big Five level and, based on the NEO-BFAS, the aspect level. MPs were more extraverted, conscientious, and open than the average voter. On the elite level, liberal MPs were more agreeable and, on the aspect level, more compassionate but not more polite than conservative MPs. MPs in center parties had stronger power aspirations and were less agreeable and more extraverted than MPs in peripheral parties. On the aspect level, MPs in center parties were more assertive and enthusiastic and less polite. Conscientiousness and Agreeableness were associated with power aspiration, but Extraversion was not because the assertiveness effect was suppressed by a non-effect for enthusiasm. The inclusion of the aspect level explains null findings at the Big Five level and adds important nuances to the personality portrait of political elites.
