What are the principles of contagious why things catch on?

1. Social currency: People are more likely to talk about and share things that make them look good, knowledgeable, or connected. When something provides social currency, such as information or experiences that make people feel special or part of an exclusive group, it tends to catch on.
2. Triggers: Triggers are reminders or cues that prompt people to think about a particular product, idea, or content. When something is triggered frequently in people's everyday environments, they are more likely to remember and talk about it, leading to increased contagiousness.
3. Emotion: Emotion plays a significant role in driving people to share and engage with content. High-arousal emotions like awe, excitement, or anger can make things more contagious by evoking strong reactions and encouraging people to spread the word.
4. Public visibility: When something is more visible and easily observable, it becomes more likely that people will imitate or adopt it. Public visibility also makes it easier for people to talk about and share with others.
5. Practical value: People tend to share things that have practical or useful value. Providing valuable information or benefits that can help others saves them time or money, making it more likely that they will share it with their network.
6. Stories: Stories have a natural appeal and are more likely to be retold. By embedding ideas or information in a narrative format, it becomes easier for people to remember and share, increasing contagiousness.

Summary of Contagious book

"Contagious" by Jonah Berger is a book that explores the science behind why certain ideas, products, or behaviors become popular and others do not. The author presents six principles that contribute to the spread of contagious ideas: Social Currency, Triggers, Emotion, Public, Practical Value, and Storytelling.

Social Currency refers to the idea that people are more likely to share or talk about things that make them look good or enhance their social status. Triggers are triggers in our environment that remind us of a particular brand or idea and prompt us to talk or think about it. Emotion plays a significant role in making ideas or products memorable and shareable. Certain emotions like awe, anger, or amusement can greatly increase the chances of something going viral.

Publicizing an idea or product makes it more visible and increases the likelihood of others adopting it. Practical Value means that people are more likely to share things that have practical tips or useful information. Lastly, storytelling is a powerful tool in creating contagious ideas because narratives are more engaging and easier to remember than facts or statistics.

Berger supports each principle with real-world examples and case studies, drawing insights from marketing campaigns, successful products, and cultural phenomena. He also provides practical advice and strategies for applying these principles to make one's own ideas or products more contagious.

In conclusion, "Contagious" explores the underlying factors that make ideas or products go viral. It provides readers with a framework to understand and apply these principles, ultimately helping them create and spread contagious ideas in their own personal or professional lives.
