Does sociability predict civic involvement and political participation?

In contemporary history as well as in political science, a strong associational life known as sociability is thought to explain the roots of modern democracy by establishing a link between the increasing availability of free time to the middle classes, increasing willingness to gather with others in circles or associations, and increasing social capital. In personality psychology, sociability is related to prosocial behavior (i.e., the need for affiliation, agreeableness, openness, and extraversion), whose importance in different political behaviors is increasingly recognized. In the present article, we carried out 5 studies (N = 1,429) that showed that political and associative sociability (a) can be reliably assessed, can have cross-cultural validity, and are properly associated with general social interest measures and personality domains and facets in the five-factor model; (b) do not overlap with similar concepts used in political psychology to account for political participation (political expertise, political interest, political self-efficacy); and (c) predicted political and nonpolitical group membership as well as observable choices in decision-making tasks with political and nonpolitical outcomes. The results are discussed, taking into consideration the extent to which specific facets of sociability can mediate between general personality traits and measures of civic involvement and political participation in a holistic model of political behavior.
