“Picture a smart person,” said Graham. “You don’t imagine somebody who is really good at talking to people, you picture someone really awkward."

I don't at all, in fact I find that kind of thinking highly insulting. Being a smart person in my experience is often highly correlated with being able to effectively communicate and discuss with others.

I don't think there is a correlation between them. Rather, I think that if there are two people who have the same level of intelligence, the one who is a better communicator (and this is more often a trait found in extroverts) comes across as smarter because they can transmit their ideas better.
