🦠 Contagious: Why Things Catch On
📚 Book Report: 🦠 Contagious: Why Things Catch On by Jonah Berger
💡 Overview
- 🗣️ “Contagious” explores the science behind why certain products, ideas, and behaviors spread rapidly through word-of-mouth and social influence.
- 👨🏫 Author Jonah Berger, a Wharton marketing professor, argues that virality isn’t accidental but can be engineered by understanding specific psychological and social drivers.
🔑 Key Concepts: The STEPPS Framework
Berger proposes six key principles (STEPPS) that make things contagious:
- 🪙 Social Currency: People share things that make them look good, smart, or like insiders. Sharing remarkable, exclusive, or interesting content enhances their social image.
- ⏰ Triggers: Ideas or products linked to common environmental cues (triggers) stay top-of-mind and are talked about more often. Think “KitKat and coffee break.” ☕
- 🥲 Emotion: Content that evokes high-arousal emotions (like awe, excitement, anger, humor, or anxiety) is more likely to be shared than content evoking low-arousal emotions (like sadness or contentment). ❤️ When we care, we share.
- 👁️ Public: Making behavior or product usage visible encourages imitation. 👀 If people can see others doing something, they are more likely to do it themselves (“Monkey see, monkey do”).
- 💡 Practical Value: People share useful information or advice that helps others solve problems or improve their lives. This stems from an innate desire to help. 🙌
- 📖 Stories: Information is often shared in the form of narratives. Embedding a product or idea within a compelling story makes it more engaging, memorable, and likely to be passed on.
🎯 Core Argument
- 📣 The book contends that word-of-mouth marketing is significantly more effective than traditional advertising because it’s more persuasive and targeted.
- 🤔 Berger posits that making something “catch on” is achievable by applying the STEPPS principles, rather than relying on luck, large advertising budgets, or solely targeting “influencers.” The message itself is often more important than the messenger. 🗣️
👍 Strengths
- ✅ Provides a clear, actionable framework (STEPPS) backed by research.
- 📊 Uses numerous engaging and memorable case studies (e.g., Blendtec’s “Will It Blend?”, the hidden bar Please Don’t Tell, Snapple facts) to illustrate concepts.
- ✍️ Written in an accessible and easy-to-understand style.
👎 Weaknesses/Critiques
- 🗓️ Some examples, while illustrative, might feel slightly dated as the social media landscape evolves rapidly.
- 🧩 The framework, while powerful, might oversimplify the complex interplay of factors (including timing and luck) that contribute to true viral success.
💯 Overall Recommendation
- ⭐ “Contagious” is highly recommended for marketers, business owners, content creators, social media managers, and anyone seeking to understand how ideas spread and influence behavior. It offers practical insights into crafting messages and products that people are motivated to share. ✨

- 🧠 Made to Stick: Why Some Ideas Survive and Others Die by Chip Heath & Dan Heath: Explores what makes ideas memorable and impactful, using the SUCCESs framework (Simple, Unexpected, Concrete, Credible, Emotional, Stories). Complements “Contagious” by focusing on the stickiness within an idea.
- 🗣️ Influence: The Psychology of Persuasion by Robert Cialdini: A foundational text on the psychological principles (reciprocity, commitment/consistency, social proof, authority, liking, scarcity) that cause people to say “yes.” Provides a broader understanding of the persuasion tactics often underlying contagious content.
- 📱 Hooked: How to Build Habit-Forming Products by Nir Eyal: Focuses on creating products users return to repeatedly without conscious thought, using the “Hook Model” (Trigger, Action, Variable Reward, Investment). Relevant for making behaviors around a product contagious.
- 🐮 Purple Cow: Transform Your Business by Being Remarkable by Seth Godin: Argues that in a cluttered marketplace, products need to be inherently remarkable (like a purple cow) to get noticed and talked about. Aligns with the “Social Currency” and “Emotion” aspects of STEPPS.
⚖️ Contrasting Perspectives (Different Angles on Popularity/Success)
- 📍 The Tipping Point: How Little Things Can Make a Big Difference by Malcolm Gladwell: While also exploring epidemics of ideas, Gladwell emphasizes the role of specific types of people (Connectors, Mavens, Salesmen), the “Stickiness Factor,” and the “Power of Context,” offering a different framework than STEPPS. Berger specifically argues against the oversized importance often attributed to “influencers.”
- 📈 Hit Makers: The Science of Popularity in an Age of Distraction by Derek Thompson: Argues that hits often blend familiarity with surprise (“MAYA - Most Advanced Yet Acceptable”) and benefit significantly from distribution and network effects, sometimes more than inherent contagiousness.
- 🌐 Diffusion of Innovations by Everett M. Rogers: A classic academic work outlining how innovations spread through social systems over time, focusing on adopter categories (Innovators, Early Adopters, etc.) and the characteristics of innovations that influence adoption rates. Provides a more macro, sociological perspective.
