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.
