Influence by Robert Cialdini

Description

If you only read one book on why people say yes, make it this one. Robert Cialdini distills decades of research into seven principles of persuasion — reciprocity, commitment and consistency, social proof, authority, liking, scarcity, and unity — with vivid stories that make each one stick. For referral and growth marketers it’s essential, because it explains the exact levers that make people share, refer, and buy (social proof and reciprocity underpin nearly every referral program). Honest caveat: it’s more foundational psychology than a step-by-step tactics manual, and a few examples show their age. But the mental models are permanent, and you’ll spot them everywhere once you’ve read it.
