The Book That Changed Everything

The Book That Changed Everything

Influence: The Psychology of Persuasion is published — a book so powerful that Warren Buffett personally recommended it. It would go on to sell over 7 million copies, be translated into 44 languages, and be named one of Fortune's "75 Smartest Business Books" ever written.

The Godfather of Influence

Dr. Robert Cialdini


Dr. Cialdini has spent his entire career on a single scientific question: what leads people to say yes? His books, including Influence and Pre-Suasion, have sold more than 7 million copies in 44 languages and are New York Times, Wall Street Journal, and USA Today bestsellers.

He has been elected to the American Academy of Arts & Sciences and the National Academy of Sciences. Through the Institute, he and his team teach, train, and coach organizations to put this science to work ethically, and reach their goals.
