Are you racist and don't know it?

I heard about this Harvard study that created an online test you can take to determine your biases. Are you racist? I think most people would say "of course not." But are you really? Do you have a bias against handicapped people? or old people? or fat people? or men? Try these tests to find out. I would love to hear feedback from people about their results. If you don't want to admit your bias just tell me if you feel like these tests are accurate or if you agreed with your results or anything about bias against these minority groups.
