Chapter 4: Public: When Behavior Breeds Contagiousness

Humans are social creatures, and we instinctively mimic the actions of others. In this chapter, Berger unravels the concept of social proof, demonstrating how people are more likely to adopt behaviors when they see others doing the same. By making our ideas more observable and public, we can encourage widespread adoption and create a self-sustaining cycle of contagiousness.

Chapter 5: Practical Value: The Utility of Virality

Utility is the cornerstone of contagiousness. People actively seek out and share information that is helpful, useful, or even life-changing. Berger illustrates how we can design ideas that offer practical value, making them indispensable and, in turn, shareable by word of mouth.
