At the beginning of the test, you are asked what your attitudes toward blacks and whites are. I answered, as I am sure most of you would, that I think of the races as equal. Then comes the test. You’re encouraged to complete it quickly. First comes the warm-up. A series of pictures of faces flash on the screen. When you see a black face, you press e and put it in the left-hand category. When you see a white face, you press i and put it in the right-hand category. It’s blink, blink, blink: I didn’t have to think at all.
