Critics Review
Amazing … [saying no] is not just about freeing up the diary it’s about living freely and positively with who you are * Chris van Tulleken, ‘What’s Up Docs?’ *
A powerful book. If you’ve ever compromised your principles to please others, DEFY will give you the will-and skill-to stand up for yourself. * Adam Grant, #1 New York Times bestselling author of Hidden Potential *
In DEFY, Sunita Sah brilliantly reframes our understanding of defiance-from an act of mere rebellion to a vital tool for personal growth and social change. This book is a powerful, even transformative, read for anyone who’s ever felt the tension between doing what’s expected and doing what’s right. * Daniel H. Pink, #1 New York Times bestselling author of The Power of Regret, Drive, and When *
Dr. Sah is leading the charge on the science of compliance and defiance. DEFY changes our understanding about true consent and true dissent, a real yes and a real no… A must-read for all. * Dr. Robert Cialdini, New York Times bestselling author of Influence *
We all have to navigate the world by choosing what we will or will not accept for ourselves, but for the first time Dr. Sunita Sah is delivering the science behind those choices. What do you do when you’re faced with a big decision? What do you do when you feel pressured to make a particular choice? From how to give your best yes to your truest no, DEFY can help us handle those big decisions with integrity, compassion, and candor. * Annie Duke, professional poker play and author of Quit: The Power of Knowing When to Walk Away *
