Book Review: Contagious

Quick Review of an interesting book Contagious!

By BoodaPublished about a month ago 3 min read

“Contagious: How to Build Word of Mouth in the Digital Age” by Jonah Berger is a compelling exploration of why certain ideas, products, or messages become viral while others fade into obscurity. Drawing on extensive research from the fields of psychology, sociology, and marketing, Berger reveals the underlying principles behind contagiousness and provides practical insights for creating content that captivates audiences and drives word-of-mouth sharing. Here’s a detailed summary of each chapter:

Introduction: Why Things Catch On

In the introduction, Berger sets the stage by posing the fundamental question: why do some things become popular while others languish in obscurity? He introduces the concept of contagiousness and explains that understanding the psychology behind it can help marketers create content that resonates with audiences and sparks sharing. Berger teases some of the key principles that will be explored in the subsequent chapters, laying the groundwork for the rest of the book.

Chapter 1: Social Currency

Berger kicks off the first chapter by discussing the concept of social currency—the idea that people share things that make them look good to others. He explores how individuals use the things they share to craft their identities and signal their social status. Berger provides examples of products and experiences that offer social currency, such as luxury goods and exclusive events, and explains how marketers can leverage this principle to make their content more shareable.

Chapter 2: Triggers

In the second chapter, Berger delves into the concept of triggers—stimuli that prompt people to think about related concepts or ideas. He explains that effective triggers are contextually relevant and occur at the right time and place to drive action. Berger provides examples of triggers in action, such as the association between peanut butter and jelly or the link between Kit Kat bars and coffee breaks, and offers insights into how marketers can create triggers that remind consumers of their products or messages.

Chapter 3: Emotion

Berger explores the role of emotion in driving sharing behavior in the third chapter. He argues that content that evokes high-arousal emotions, such as awe, excitement, or anger, is more likely to be shared than content that elicits low-arousal emotions. Berger provides examples of emotionally charged campaigns that have gone viral, such as Dove’s “Real Beauty Sketches” and Nike’s “Find Your Greatness,” and offers strategies for harnessing the power of emotion to create contagious content.

Chapter 4: Public

In the fourth chapter, Berger discusses the principle of public visibility—the idea that people are more likely to imitate behaviors that they can observe. He explores how making products or behaviors more observable can increase their likelihood of adoption and sharing. Berger provides examples of public displays of consumption, such as wearing branded clothing or displaying bumper stickers, and explains how marketers can leverage this principle to make their products or messages more visible to others.

Chapter 5: Practical Value

Berger examines the concept of practical value in the fifth chapter—the idea that people share things that are useful or helpful to others. He argues that content that offers practical value is more likely to be shared because it serves a functional purpose. Berger provides examples of content that offers practical value, such as life hacks, how-to guides, and useful tips, and offers strategies for creating content that meets consumers’ needs and solves their problems.

Chapter 6: Stories

In the final chapter, Berger explores the power of storytelling in driving sharing behavior. He argues that stories are inherently contagious because they are easy to remember, emotionally engaging, and socially shareable. Berger provides examples of successful storytelling campaigns, such as the ALS Ice Bucket Challenge and the “Share a Coke” campaign, and offers insights into how marketers can use storytelling techniques to create compelling narratives that resonate with audiences and inspire them to share.
