Contagious
Jonah Berger · 2013
Contagious (2013) is a book by Jonah Berger on business & strategy. Wharton marketing professor Jonah Berger dissects why some ideas, products, and stories spread while others die, distilling the science of word of mouth into six shareability principles he calls STEPPS.
Turns "going viral" from luck into engineering, giving you six repeatable levers that make ideas, products, and messages spread by word of mouth.
Two of the ideas you’ll keep
The Clif summary of Contagious pulls out 7 insights. Here are the first two.
- Virality is engineered, not lucky, and it lives in the message, not the messenger. Berger's research shows only about 7% of word of mouth happens online and that ordinary people, not a rare class of 'influentials,' drive most sharing, so the question isn't who to reach but what makes content contagious. His answer is the STEPPS framework: Social Currency, Triggers, Emotion, Public, Practical Value, and Stories.
- Social Currency: people share things that make them look good. Just as we buy cars and clothes that signal status, we pass along remarkable, insider, or scarce information to seem sharp and in-the-know, which is why a secret bar hidden behind a phone booth (Please Don't Tell) generates more buzz than one that advertises, and why game mechanics like airline status tiers make people want to show off their standing.
