'From bullying on the playground to sexual harassment in the workplace, perfectly nice people often do perfectly awful things. But why? In this thoughtful and beautifully written book, Sanderson shows how basic principles of social psychology explain such behavior—and how they can be used to change it. A smart and practical guide to becoming a better and braver version of ourselves' Daniel Gilbert, author of Stumbling on Happiness 


'Much of what enables evil people to do evil things is that we stand idly by and let them. In this powerful, well-written book, Catherine Sanderson explains what psychology has taught us about why good people so often do nothing and offers wise suggestions that will enable more of us to step up and be "moral rebels" when the situation calls for it. If you have ever regretted being silent (and who hasn't?) this is the book for you' Barry Schwartz, author of The Paradox of Choice


'Catherine Sanderson, like no other psychologist, invades our minds. Her riveting storytelling challenges us to rethink why we avert our eyes to evil, tolerate bullying, and excuse unforgivable workplace behavior. She plumbs the depths of social norms that too often prevent good people from being good and points to steps all of us can take to become “moral rebels’’ whose voices can change society for the better'
Walter V. Robinson, former editor of the Boston Globe’s Spotlight team
