Contagious: Why Things Catch On

Introduction to 'Contagious: Why Things Catch On'

In a world brimming with products, ideas, and messages constantly competing for attention, understanding why certain things become popular while others do not is both an art and a science. In 'Contagious: Why Things Catch On', Jonah Berger, a renowned professor of marketing at the Wharton School, delves into the secrets of viral success. Through compelling narratives and rigorous research, Berger unveils the mechanisms that propel ideas, products, and behaviors to catch on and become contagious.

Detailed Summary of the Book

'Contagious: Why Things Catch On' is an exploration into the magic behind viral marketing. Berger presents a clear and accessible framework that helps readers understand what makes things spread. The book is grounded in the author’s years of academic research combined with real-world examples. Berger identifies six key principles, encapsulated in the acronym STEPPS: Social Currency, Triggers, Emotion, Public, Practical Value, and Stories. Each chapter of the book explores one of these principles and how it contributes to word-of-mouth and social transmission.

For instance, Social Currency describes how people share things that make them look good, while Triggers are reminders embedded in our environment, prompting us to think about associated ideas or products. The book is filled with examples ranging from the popularity of the $100 cheesesteak to the viral spread of a quirky advertisement for a blender. This approach not only makes the book engaging but also illustrates how these principles can be applied across different contexts.

Key Takeaways

• Virality is not random; it can be engineered using the STEPPS framework.
• Creating content that has social currency increases the likelihood of it being shared.
• Simple triggers can have a profound impact on making ideas top-of-mind.
• Emotional arousal, especially high arousal emotions such as awe and excitement, boosts sharing.
• Observability matters: Making behavior public elevates visibility and spread.
• Offering practical value ensures that content is both useful and shareable.
• Stories are powerful vessels for information and provide mental shortcuts for better recall and sharing.
