The Psychology of Persuasion

Six universal principles quietly drive people to say yes.

by Robert B. Cialdini

Cialdini distills years of research into six principles of persuasion: reciprocity, commitment and consistency, social proof, liking, authority, and scarcity. He shows how compliance professionals use these levers and how to recognize when they are being used on you. The book blends rigorous psychology with vivid real-world stories.

Founders persuade constantly, with investors, customers, and recruits, and these six principles are the deepest framework for doing it ethically and effectively. It also helps you design pricing, landing pages, and sales motions grounded in how people actually decide.
