What are some ways to evaluate someone's intelligence?

Are You Creative?
Intelligence is impossible without creativity. A man without creativity is like a machine that can efficiently execute the functions for which it is designed or programmed, but can't do a single thing more. An intelligent person is highly creative, and he never repeats the same mistake twice. When Thomas A. Edison said, "I have not failed. I've just found 10,000 ways that won't work," he was not talking about perseverance as most people would like to imagine, but exhibiting his creativity of finding 10,000 new ways to do the same thing. An intelligent person always discovers another method if the present method does not work.
