How many times have you wanted to object, disagree, or opt out of something–but ended up swallowing your words, shaking your head, and just going along? Analyzing cases from corporate corruption to sexual abuse to everyday acquiescence at work, the doctor’s office, and in our personal lives, award-winning organizational psychologist Dr. Sunita Sah delves deep into why the pressure to comply is a corrosive and often invisible force in our society. With her own revelatory research, she radically transforms our idea of defiance from a misunderstood negative trait into a crucial, positive force for personal and societal change. Taking us through her five stages of defiance, Dr. Sah equips readers with simple tools to make decisions that align with their values. Defy is the essential playbook for how to speak up and act when it matters most.
