title = "Political Extremism",
abstract = "While the field of political psychology has overwhelmingly focused on political orientation (i.e., ideological content), this chapter proposes that political extremism (i.e., ideological strength) at the left and right also matters for a range of important variables. The main argument is that feelings of distress prompt a desire for epistemic clarity, which increases the appeal of the clear-cut answers that politically extreme movements provide for pressing societal problems. The chapter subsequently proposes that political extremism in most cases is a problem for societies. We review evidence that politically extreme beliefs are associated with overconfidence in the correctness of one{\textquoteright}s beliefs and knowledge about the world, an increased susceptibility to beliefs that are not supported by science or reason, and intolerance of competing belief systems or groups perceived as ideologically different. We conclude by articulating a few limitations and research directions in this research domain.",
