Theory on word of mouth
Berger's theory of what spreads with word of mouth is based on six key principles: social currency, triggers, emotion, public, practical value, stories.
Six key principles
- Social Currency – People talk about what makes them look good.
- Triggers – People talk about items associated with ideas and activities in people's lives because they're reminded of it.
- Emotion – People share what gives them high-arousal emotions.
- Public – People will do what other people are doing.
- Practical value – People will share what has practical value.
- Stories – People will share stories.
His 2013 book, Contagious: Why Things Catch On, was based on research and real-world examples.
