I believe that we are only as intelligent as the ideas that we are able to articulate clearly. Mr. Adams seems to have a similar idea.

“I have a theory that the rational side of your brain is only as strong as your language skills. You assume that a person who is logical can, as a result of that       logical facility, write a clear and persuasive sentence. But I think causation works the other way. I think language creates logic. The stronger your language     skills are, the better your logic becomes. You can never be more rational than your vocabulary allows.” -Scott Adams

The kid you knew 20 years ago that would calculate increasingly more digits of pi during holidays probably has a higher IQ than you.  You thought he was weird because he couldn’t communicate well, though.
