The self-perception that one is able to assess others in a fair and accurate way is challenged as the authors explore the hidden biases we all carry from a lifetime of exposure to cultural attitudes about age, gender, race ethnicity, religion, social class, sexuality, disability status, and nationality. This book questions the extent to which our perceptions of social groups -- without our awareness or conscious control -- shape our likes and dislikes and our judgments about people's character, abilities and potential. Biases based on experience are revealed with the Implicit Association Test.
