—Daniel Gilbert, bestselling author of Stumbling on Happiness

—Robert Cialdini, bestselling author of Influence and Pre-Suasion

“Everyone should read this book! . . . It is rare that one overarching principle can explain so much, but Michele Gelfand nails it with her brilliant analysis of how tightly or loosely people adhere to social norms.
