Demagoguery is a political phenomenon and a key concept studied across political science, rhetoric, and communication studies. This academic concept investigates the strategic use of manipulative rhetorical techniques that appeal to the prejudices, emotions, fears, and popular desires of a populace, rather than relying on rational argument or evidence, typically employed to gain or consolidate political power. Research in this area examines the characteristics of such appeals, the social and psychological mechanisms that facilitate their effectiveness, historical examples of their deployment, and their significant impact on political discourse, democratic institutions, and social cohesion.
