Populist rhetoric frequently includes allegations about political corruption, these allegations are often vague and unverifiable. In this chapter we explore the meaning of “corruption” for populist politicians, and we explore the normative implications of populist corruption talk. We contend that social scientific analyses of corruption do not provide a sufficient response to populist corruption talk because they lack a normative element. We propose that linking corruption to the vice of sloth provides a more constructive means of countering populist allegations.
