The Psychology of Persuasion

Robert Cialdini spent three years undercover — working at used car dealerships, telemarketing firms, and fundraising organizations — to study the psychology of persuasion. He distilled his findings into six universal principles of influence that explain why people say yes, and how to apply these principles ethically in business and life.

Cialdini, a social psychologist at Arizona State University, wanted to understand the techniques used by "compliance professionals" — salespeople, advertisers, and con artists. His research revealed that influence operates through six predictable psychological shortcuts that evolved to help humans navigate a complex social world.
