Influence, New and Expanded: The Essential Guide to the Psychology of Influence and Persuasion

The foundational and wildly popular go-to resource for the science of influence and persuasion―a renowned international bestseller, with over 5 million copies sold―now revised adding: new research, new insights, new examples, and online applications.

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 on human behavior ethically in business and everyday settings. Using memorable stories and relatable examples, Cialdini makes this crucial aspect of behavioral science surprisingly easy to understand. With Cialdini as a guide, you don’t have to be a scientist to learn how to use this science in your own decision-making.

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. You may think you know these principles of social psychology, but without understanding their intricacies, you may be ceding their power to someone else.

Cialdini’s Principles of Persuasion:

Reciprocation
Commitment and Consistency
Social Proof
Liking
Authority
Scarcity
Unity, the newest principle for this edition
Understanding and applying the principles ethically is cost-free and deceptively easy. Backed by Dr. Cialdini’s 35 years of evidence-based, peer-reviewed scientific research―including a three-year field study on what leads people to change―Influence, New and Expanded EPB is a comprehensive guide to using these principles to move others in your direction.
