Chapter 1 Whats Contagious

"Contagious: How to Build Word of Mouth in the Digital Age" is a bestselling book written by Jonah Berger, a professor of marketing at the Wharton School at the University of Pennsylvania. The book explores why certain ideas, products, or messages become viral and spread rapidly through word of mouth, while others don't.


In "Contagious," Berger presents a framework consisting of six principles that can make something more likely to be shared and talked about. These principles are referred to by the acronym STEPPS:


  1. Social Currency: People share things that make them look smart, cool, or exclusive. By understanding how to make your idea or product enhance someone's social status, you can increase its shareability.


  1. Triggers: Certain triggers prompt people to think about and talk about specific topics or brands. By associating your idea or product with relevant triggers, you can increase the likelihood of it being top of mind and spoken about.


  1. Emotion: Content that evokes strong emotions, whether positive or negative, tends to be more contagious. Understanding how to tap into the right emotions can help increase sharing.


  1. Public: Making things more observable or public can lead to increased sharing. When people see others engaging with an idea or product, they are more likely to follow suit and share it themselves.


  1. Practical Value: Offering practical value to others encourages sharing. If people find your idea or product useful, they will want to spread the word to help their friends and colleagues.


  1. Stories: Narratives have been a powerful tool for communication throughout human history. Crafting compelling stories around your idea or product makes it easier for others to remember and share it.


Berger combines academic research, real-world examples, and practical advice to illustrate each principle and provide actionable strategies for building contagious content in the digital age.
