Influence
by Robert Cialdini
The foundational survey of compliance research. Cialdini identifies six (now seven, in the expanded edition) principles that explain why people say yes: reciprocity, commitment, social proof, authority, liking, scarcity, and unity. Every other book on this list either builds on these principles or argues with them.
Key takeaway
People do not make decisions rationally. They rely on mental shortcuts (heuristics) that can be understood and ethically leveraged. Learn to recognise these six patterns and you will see them everywhere.
