Crucial Influence reveals the personal, social, and structural sources that shape human behavior and teaches a method for using these sources to change behavior.

Crucial Influence book


Fifteen years ago, Crucial Influence (formerly Influencer) introduced the business world to a bold idea: true leadership depends not on position or personality, but on an understanding of how the world works. Drawing on 50 years of social science research and the study of leaders around the world, Crucial Influence reveals a method for engaging personal, social, and structural forces to influence behavior. The Crucial Influence course expands on the now-famous model of leadership outlined in the book to assist leaders as they attempt to do that which defines leadership: influence others for lasting results.
