Perfect for you if...

You work in sales, marketing, or negotiations and want to understand the mechanics behind what actually moves people to decide.
You're curious about your own decision-making and want to spot when you're being influenced (and how to do it ethically yourself).
You've noticed certain tactics work everywhere from restaurants to politics and want to know the underlying science instead of just the tricks.

Maybe not for you if...

You're looking for manipulative shortcuts to trick people into doing what you want without earning their trust.
You prefer narrative-driven storytelling over research-backed analysis and case studies.
You want a quick read. This is thorough and dense, not a breezy 100-page summary.

About this book

An examination of the psychological principles that guide human behavior and decision-making. The work explores six key principles of influence: reciprocity, commitment and consistency, social proof, authority, liking, and scarcity. Through research and real-world examples, Cialdini demonstrates how these principles operate in sales, marketing, and everyday interactions. The expanded edition includes additional material on ethical applications and modern contexts.
