I guess I have to agree - I mean, I like to think I can tell whether a person is in general bright or not - just by things like the way their eyes look and the expressions on their faces, what they say, how they talk. I still think those things do tell you something, but I don't know exactly what that something would be.
My ongoing battle with statistics has me wondering about my own intelligence. I've done really well in every other math related course I've ever taken. Of course the last one of those was back in high school twenty years ago. Does intelligence fade with age?
