Is there a populist personality? Populist attitudes, personality, and voter preference in Australian public opinion

Abstract

ABSTRACT This paper investigates whether personality affects support for populist parties either directly or indirectly through “populist attitudes.” It theorizes that populist attitudes should be disambiguated into their component facets and that the attitudinal components of populism are best understood as loosely related characteristic adaptations, which mediate the relationship between personality and vote choice. Using data from a nationally representative survey of 2200 Australians fielded prior to the general election in 2019, the paper demonstrates that the three attitudinal components of populism (People-centrism, Anti-elitism, and a Manichean outlook) are weakly associated with one another and distinctively connected with underlying personality traits. Our results indicate that populist attitudes are better conceptualized as a cluster of weakly related psychological tendencies rather than as a coherent worldview or personality. Mediation analysis indicates that personality traits affect support for populist parties both directly and indirectly through the attitudinal components of populism.
