Unconscious bias: persistent, unintentional prejudiced behavior that clashes with our consciously held beliefs. We know that it exists, to corrosive and even lethal effect. We see it in medicine, the workplace, education, policing, and beyond. But when it comes to uprooting our prejudices, we still have far to go. With nuance, compassion, and ten years' immersion in the topic, Jessica Nordell weaves gripping stories with scientific research to reveal how minds, hearts, and behaviors change. She scrutinizes diversity training, deployed across the land as a corrective but with inconsistent results. She explores what works and why: the diagnostic checklist used by doctors at Johns Hopkins Hospital that eliminated disparate treatment of men and women; the preschool in Sweden where teachers found ingenious ways to uproot gender stereotyping; the police unit in Oregon where the practice of mindfulness and specialized training has coincided with a startling drop in the use of force. Captivating, direct, and transformative, brings good news. Biased behavior can change; the approaches outlined here show how we can begin to remake ourselves and our world.
