Overall Summary:

“Contagious: Why Things Catch On” by Jonah Berger explores the science behind why certain ideas, products, and messages become popular and spread like wildfire, while others fade into obscurity. The author presents six key principles that drive contagiousness: social currency, triggers, emotion, public visibility, practical value, and storytelling.

Berger argues that people are more likely to share and talk about things that make them look good or enhance their social status, which he refers to as social currency. He also emphasizes the importance of triggers, which are cues that remind people of a particular product or idea and prompt them to talk about it. Emotion plays a significant role in contagiousness, as content that evokes strong emotions is more likely to be shared.

Public visibility refers to the idea that people are more likely to imitate behaviors that they see others engaging in. Practical value is another key principle, as people are more likely to share information that they find useful or helpful. Lastly, storytelling is a powerful tool for creating contagious content, as stories are more memorable and engaging than simple facts or messages.

Throughout the book, Berger provides numerous examples and case studies to illustrate his principles, such as the viral success of Blendtec’s “Will It Blend?” campaign and the story of Subway spokesperson Jared Fogle. He also delves into the psychology behind why certain rumors and stories persist while others fade away.

Overall, “Contagious” offers valuable insights into the factors that contribute to the spread of ideas and products, providing readers with practical strategies for creating contagious content.

 

Key Concepts and Terminology:

1. Social Currency: Social currency refers to the value that people place on the information they share with others. It is the idea that people are more likely to talk about and share things that make them look good or enhance their social status.

2. Triggers: Triggers are cues or stimuli that prompt people to think about and talk about a particular product or idea. Triggers can be external, such as a visual or auditory cue, or internal, such as a thought or memory.

3. Inner Remarkability: Inner remarkability refers to the unique and interesting aspects of a product or idea that make it worth talking about. It is about finding the “wow” factor that sets something apart from the competition and makes it stand out.

4. Game Mechanics: Game mechanics are elements of a game, such as challenges, rewards, and competition, that can be applied to non-game contexts to engage and motivate people. By incorporating game mechanics into a product or idea, it can become more engaging and shareable.

5. Scarcity and Exclusivity: Scarcity and exclusivity create a sense of urgency and desirability around a product or idea. By making something limited or exclusive, people are more likely to want it and talk about it.

6. Social Proof: Social proof is the idea that people are influenced by the actions and behaviors of others. When people see others engaging with a product or idea, they are more likely to perceive it as valuable and desirable.

7. Herd Mentality: Herd mentality refers to the tendency of individuals to conform to the actions and behaviors of a larger group. People are more likely to follow the crowd and make decisions based on what others are doing.

8. Observability: Observability refers to the visibility of a product or idea. When something is easily observable and noticeable, it is more likely to be talked about and shared.

9. Social Influence: Social influence is the impact that others have on an individual’s thoughts, feelings, and behaviors. It can shape people’s opinions and actions, leading them to conform to social norms and trends.

10. Virality: Virality refers to the rapid spread and popularity of a product or idea through social sharing and word-of-mouth. When something goes viral, it quickly gains widespread attention and engagement.

 

Case Studies or Examples:

1. Please Don’t Tell: The book mentions a speakeasy bar called Please Don’t Tell, which uses the concept of secrecy to create social currency. The bar is known for its exclusivity and hidden location, and customers are given a small business card with the words “Please Don’t Tell” and a phone number. This creates a sense of intrigue and exclusivity, encouraging customers to share their experience with others.

2. Walt Disney World: The book discusses how Walt Disney World effectively triggers excitement and word-of-mouth by creating memorable experiences for children. The theme park offers thrilling rides, magical encounters with beloved characters, and immersive environments. These triggers lead to children eagerly sharing their experiences with others, generating buzz and attracting more visitors.

3. Halal Chicken and Gyro vs. Halal Guys: The book presents the example of two food carts, Halal Chicken and Gyro and Halal Guys, located across the street from each other in New York City. Despite offering similar food, Halal Chicken and Gyro has long lines of customers, while Halal Guys does not. This is due to social proof – people assume that the longer the line, the better the food must be. The herd mentality leads people to choose the cart with the longer line, creating a social influence that affects their decision-making.

4. University of Arizona Mental Health Program: The book mentions Koreen Johannessen, a clinical social worker at the University of Arizona. Johannessen realized that instead of focusing on treating ongoing mental health issues, it would be more effective to prevent them before they start. By addressing the root causes and providing support and resources to students, the university’s mental health program aims to create a positive social influence and prevent future problems.

5. Organ Transplant Refusals: The book discusses a study by MIT professor Juanjuan Zhang on organ transplant refusals. Zhang found that social proof plays a role in people’s decisions to turn down available kidneys. If a kidney has been turned down by many others on the transplant list, people assume it must be of low quality and are more likely to refuse it. This demonstrates how social influence and the behavior of others can impact decision-making in important situations.
