Contagious: Why Things Catch On

Contagious: Why Things Catch On examines the science behind why certain products, ideas, and behaviors spread rapidly through populations while others fail to gain traction. Author Jonah Berger distills years of research into six key principles that drive things to become viral or contagious in both the online and offline worlds. Through case studies and research examples, Berger analyzes successful marketing campaigns, urban legends, and social movements to uncover patterns in how information spreads. The book presents a framework called STEPPS (Social currency, Triggers, Emotion, Public, Practical value, and Stories) to explain the core elements that make content shareable. Each chapter focuses on one principle and provides actionable insights for businesses, marketers, and individuals who want their messages to reach wider audiences. The concepts are supported by data from behavioral experiments and real-world examples ranging from luxury goods to workplace rumors. At its core, the book reveals fundamental truths about human psychology and social behavior, demonstrating how understanding these principles can help anyone craft messages that people will eagerly share with others. The framework presents a systematic approach to what was previously considered an unpredictable phenomenon.

Readers describe the book as a practical framework for understanding why content spreads, though many note it covers familiar territory. The STEPPS model (Social currency, Triggers, Emotion, Public, Practical value, Stories) gives clear structure to the concepts.
