Heffernan argues that the biggest threats and dangers we face are the ones we don't see – not because they're secret or invisible, but because we're willfully blind. She examines the phenomenon and traces its imprint in our private and working lives, and within governments and organizations, and asks: What makes us prefer ignorance? What are we so afraid of? Why do some people see more than others? And how can we change? This course demonstrates how failing to see—or admit to ourselves or our colleagues—the issues and problems in plain sight can ruin private lives and bring down corporations. The course explores how willful blindness develops and then goes on to outline some of the mechanisms, structures and strategies that institutions and individuals can use to combat it.
