Jonah Berger

Jonah Berger is an American marketing professor, scholar, and author specializing in the study of social influence, consumer behavior, and viral marketing. He is a professor at the Wharton School of Business at the University of Pennsylvania. His most famous book is Contagious: The Psychology of Viral Marketing, in which he explores why certain ideas, products, and content become popular and spread quickly. Berger offers science-based principles that help you understand how to create "contagious" content that grabs attention and spreads among people.

In addition to Contagious, he also wrote The Invisible Influence, which examines how social factors influence our decisions and behavior.
