Revealing Your Unconscious: Part 1

Would you consider yourself to be prejudiced against people who are different from you? Most of us would say no. But in the late 1990s, researchers created a test to measure biases that may be hidden from our conscious minds. Millions of people have taken it since, and not everyone likes what they've discovered. This week, we launch a two-part look at implicit bias with psychologist Mahzarin Banaji. We ask how is it that we can hold negative stereotypes — without being aware of them.
