Degrees
Famous people don't come from the Famous People Machine. They come from wombs of mostly not famous people and they grow up with mostly not famous people. We are surprised when someone we know knows someone famous.
Famous people are famous for differnet reasons, but we like famous people for one reason. Becuase they are familiar and shiny.
New is so we can tell what's old. Probably not, but it almost works. Different tells you that it's new. It's not new though, it's just different. Differently the same by most measures. 10 t-shirts mostly the same, different color and logo. Difference = very small.
