Margaret Heffernan draws on psychological studies, social statistics, interviews with relevant protagonists, and her own experience to throw light on willful blindness and why whistleblowers and Cassandras are so rare. Ranging freely through history and from business to science, government to the family, this engaging and anecdotal book will explain why willful blindness is so dangerous in a globalized, interconnected world, before suggesting ways in which institutions and individuals can start to combat it. Margaret Heffernan's thought-provoking book will force us to open our eyes.
