So here is the bottom line. If you focus in on a group like this -- this happens to be a USC game -- and you zoom in with one of those super satellite cameras and do magnification factors so you could see individual people, you would in fact see not a single crowd, just like there is not a single crowd here, but you would see these tribes that are then coming together. And from a distance it appears that it's a single group. And so people form tribes. They always have. They always will. Just as fish swim and birds fly, people form tribes. It's just what we do. But here's the rub. Not all tribes are the same, and what makes the difference is the culture.
