It only takes 7 seconds to put a label on a person based on his or her appearance.
In this video six strangers were sat in a dark room. They each talked about their interests, their hobbies. You can see that while one person is sharing something about himself, the others immediately jumped into conclusions, confining that person to a certain stereotype even without knowing what he looks like. But when the lights were turned on and they saw each other, everyone at the table gained an entirely new perspective on people. This video clip may be short, but the message is powerful. Watch!
