Jennifer Eberhardt, a Stanford psychologist who has spent her career studying unconscious racial bias, combines research findings with personal stories and practical recommendations in this accessible guide to understanding and addressing implicit prejudice. Eberhardt describes her own experiences as a Black woman in America alongside laboratory studies that reveal how bias operates even in people who consciously reject racism. She examines how implicit associations between blackness and criminality affect police officers, judges, and ordinary citizens, leading to disparate treatment in the criminal justice system. The book explores how bias affects education, housing, and employment, providing evidence of discrimination while also showing how changing contexts and practices can reduce biased behavior. Eberhardt discusses interventions she has developed with police departments, tech companies, and other organizations seeking to address bias in their operations. She maintains a tone that is urgent but not hopeless, critical but not accusatory, acknowledging that bias is a human problem that requires human solutions rather than simply identifying villains. Readers will find here both scientific understanding of how bias works and practical guidance for individuals and institutions seeking to overcome it. Essential reading for anyone concerned with racial justice who wants to move beyond good intentions to effective action.
