Influence: The Psychology of Persuasion | Robert Cialdini

The book that changed everything we know about persuasion—now revised and expanded with groundbreaking new insights.

For over four decades, Influence has been the definitive guide to understanding why people say "yes"—and how to apply these principles ethically in business, marketing, and everyday life. Written by Dr. Robert Cialdini, the world's most cited social psychologist and "Father of Persuasion," this revolutionary book reveals the hidden psychological triggers that shape human decision-making.

• Social Proof: The powerful pull of following the crowd
• Liking: Why we say "yes" to people we like—and how to build genuine rapport
