From New York Times bestselling author of Presence, renowned social psychologist, and one of the most popular TED speakers of all time Dr. Amy Cuddy, a groundbreaking exploration of how bullying hijacked our culture—and how social bravery can change it.

When social psychologist Dr. Amy Cuddy became the target of a years-long campaign of bullying that unfolded both publicly and within her profession, she found herself asking a question her research had never fully answered: How do ordinary people become part of extraordinary cruelty?

The search for that answer became an investigation into one of the defining social problems of our time. In Bullied, Dr. Cuddy draws on her own experience and decades of research to offer a powerful new understanding of how bullying doesn’t simply harm individuals—it reshapes groups, organizations, and communities into cultures of cruelty. Bringing together psychology, sociology, history, ethology, and real-world cases, she uncovers the surprisingly predictable patterns that allow bullying to spread, reveals why institutions so often fail to stop it, and explains how ordinary people can become part of sustaining it without ever intending to.

But this is not just a story of harm—it’s a story of hope. Introducing the concept of social bravery, Dr. Cuddy shows how small but courageous acts can interrupt bullying before it hardens into culture, restoring trust and altering the course of what everyone else does next.

In Bullied, you’ll discover:

Why bullying is never one person's doing—and how every response, including no response, shapes the outcome.

How a campaign of cruelty unfolds—from the first small test to the target's disappearance.

Why we struggle to believe what we're seeing—and what that delay hands the bully.

The surprising science showing how a small minority can change an entire culture.

How social bravery becomes something practiced together—not risked alone.

Part memoir, part scientific investigation, and part argument for repair, Bullied changes the way we think about bullying, courage, and the role each of us plays in shaping the cultures around us—and offers a hopeful vision of how ordinary courage can become as contagious as cruelty.
