Influence
Robert Cialdini, a social psychologist who spent years inside car lots, charity call centers, and cult recruitment sessions, distills his findings into six levers of persuasion: reciprocity, commitment and consistency, social proof, liking, authority, and scarcity. Each chapter pairs field observations with laboratory studies to show how compliance professionals exploit the mental shortcuts we use when we cannot evaluate every decision in full. Written with dry humor and a steady stream of real-world examples, the book has become a foundational text in marketing, behavioral economics, and the study of undue influence.
