Political orientation reflects beliefs, opinions, and values that are, at least in part, rooted in stable interindividual differences. Whereas evidence has accumulated with regard to the relevance of basic personality dimensions, especially concerning the sociocultural dimension of political ideology, less attention has been paid to the more specific dispositional tendency to assign a higher weight to one’s own utility above others’ (i.e., socially aversive personality), which is likely to play a pivotal role concerning the economic dimension of political ideology in particular. In three studies with over 66, 000 participants from 38 countries, we show that individuals with elevated levels in aversive personality tend to endorse more right-wing political orientations in terms of a single left–right dimension, hold relevant ideological beliefs tied to both sociocultural and economic conservatism, and report corresponding electoral voting behavior. We further provide support for the idea that this overlap between a dispositional tendency toward aversive behavior and a right-wing political orientation can be attributed to shared belief systems.
