Juan David

“The IAT is more than just an abstract measure of attitudes. It’s also a powerful predictor of how we act in certain kinds of spontaneous situations. If you have a strongly pro-white pattern of associations, for example, there is evidence that that will affect the way you behave in the presence of a black person. It’s not going to affect what you’ll choose to say or feel or do. In all likelihood, you won’t be aware that you’re behaving any differently than you would around a white person. But chances are you’ll lean forward a little less, turn away slightly from him or her, close your body a bit, be a bit less expressive, maintain less eye contact, stand a little farther away, smile a lot less, hesitate and stumble over your words a bit more, laugh at jokes a bit less. Does that matter? Of course it does. Suppose the conversation is a job interview. And suppose the applicant is a black man. He’s going to pick up on that uncertainty and distance, and that may well make him a little less certain of himself, a little less confident, and a little less friendly. And what will you think then? You may well get a gut feeling that the applicant doesn’t really have what it takes, or maybe that he is a bit standoffish, or maybe that he doesn’t really want the job.”
