Where to Start with Jonah Berger

Jonah Berger is a marketing professor at the Wharton School at the University of Pennsylvania and one of the leading researchers on social influence, word of mouth, and consumer behavior. He has published over fifty papers in top academic journals and has been recognized with awards for both his research and his teaching. His first book, Contagious: Why Things Catch On (2013), became a New York Times bestseller and introduced his STEPPS framework for understanding why things go viral. He followed it with Invisible Influence (2016), about the hidden forces that shape our decisions, and The Catalyst (2020), about how to change anyone’s mind. Berger’s work bridges the gap between academic research and practical application, making complex behavioral science accessible to marketers, entrepreneurs, and anyone trying to understand why people do what they do.

Themes: word of mouth, viral marketing, consumer behavior, social influence, psychology

The science behind why some ideas spread and others do not. Jonah Berger, a marketing professor at Wharton, spent years studying what makes content go viral, products get recommended, and ideas stick in people’s minds. Contagious distills that research into six principles that explain why things catch on.

Why Start Here

Berger has written three books, each exploring a different aspect of social influence. Contagious came first and remains his most widely read and practically useful work. The STEPPS framework (Social Currency, Triggers, Emotion, Public, Practical Value, Stories) gives you a clear mental model for evaluating whether your product, idea, or content has the ingredients to spread organically.

What makes Contagious stand out among Berger’s books is its directness. Every chapter gives you a principle you can apply immediately. Invisible Influence and The Catalyst are both valuable, but they explore subtler aspects of human behavior. Contagious tackles the question most marketers and entrepreneurs ask first: how do I get people to talk about what I am building?

What to Expect

A fast, engaging read at 244 pages. Berger writes with the clarity of a great teacher, weaving academic research into stories that stick. Each chapter covers one STEPPS principle with examples ranging from viral videos to restaurant design to public health campaigns. The book is accessible to complete beginners while still offering insights for experienced marketers.
