In the new edition of this highly acclaimed bestseller, Robert Cialdini—New York Times bestselling author of Pre-Suasion and the seminal expert in the fields of influence and persuasion—explains the psychology of why people say yes and how to apply these insights ethically in business and everyday settings. You'll learn Cialdini's Universal Principles of Influence, including new research and new uses so you can become an even more skilled persuader—and just as importantly, you'll learn how to defend yourself against unethical influence attempts.

In this revelatory book, Stephen Martin and Joseph Marks explain how in our uncertain and ambiguous world, the messenger is the message. We frequently fail to separate the idea being communicated from the person conveying it, they argue: the status or connectedness of the messenger become more important than the message itself.
