“Personality” refers to a multifaceted and enduring internal, or psychological, structure that influences patterns in a person’s actions and expressed attitudes. Researchers have associated personality with such attributes as temperament and values, but most scholarly attention has centered on individual differences in traits, or general behavioral and attitudinal tendencies. The focus on traits was reinvigorated with the rise of the Big Five personality framework in the 1980s and 1990s, when cross-cultural evidence pointed to the existence of the dimensions of openness to experience, conscientiousness, extraversion, agreeableness, and emotional stability. Studies have found these five trait dimensions to be highly heritable and stable over time, leading researchers to argue that the Big Five exert a causal impact on attitudes and behavior. The stability of traits also contrasts with more dynamic individual-level characteristics such as mood or with contextual factors in a person’s environment. Explanations of human decision-making, therefore, would be incomplete without attention to personality traits.

With these considerations in mind, political scientists have devoted an increasing amount of attention to the study of personality and citizen attitudes and behavior. The goal of this research program is not to claim that personality traits offer the only explanation for why some citizens fulfill the basic duties of citizenship, such as staying informed and turning out to vote, and others do not. Instead, scholars have studied personality in order to understand why individuals in the same economic and political environment differ in their political attitudes and actions. And accounting for the consistent influence of personality can illuminate the magnitude of environmental factors and other individual-level attributes that do shift over time.

Research on personality and political behavior has explored several substantive topics, including political information, attitudes, and participation. Major findings in this burgeoning literature include the following: (1) politically interested and knowledgeable citizens tend to exhibit high levels of openness to experience, (2) ideological liberalism is more prevalent among individuals high in openness and low in conscientiousness, and (3) citizens are more likely to participate in politics if they are high in openness and extraversion.

Although the personality and politics literature has shown tremendous progress in recent years, additional work remains to be done to produce comprehensive explanations of political behavior. Studies currently focus on the direct impact of traits on political attitudes and actions, but personality also could work through other individual-level attitudes and characteristics to influence behavior. In addition, trait effects may occur only in response to certain attitudes or contextual factors. Instead of assuming that personality operates in isolation from other predictors of political behavior, scholars can build on past studies by mapping out and testing interrelationships between psychological traits and the many other factors thought to influence how and how well citizens engage the world of politics.
