If we are talking about intellectual capacity, what I have found in my own life is that the folks who have a reputation for brilliance, I find myself having to go slow with, because they don't understand, and are not lisening anyway. This happens far more often than not. And usually the folks who no has told me are bright, when I meet them and I find common ground and get to know them, they will have enormous capacity in some area. The point is that I just don't waste any time wondering if someone is dumb or not, because the stuff I hear is usually wrong.
This statement applied in general; is yet another very profound example of your awareness.
I'm sure you don't need me to bring this to your attention but sometimes you just blow me away:)
