Totally derailing this, but it may be a trap, I just think it's fallacious in it's literal sense. I like to think of myself as a reasonably intelligent person, testing scores would reflect well above average, however I don't consider myself extremely knowledgeable. I have a colleague (friend, co-worker) who is extremely knowledgeable and doesn't even have a high school diploma. Intelligence in it's purest form is completely overrated. We regularly visit local company leaders of fortune 500 companies (GE, Bristol Myers, etc) and the guy is absolute money in front of them. He knows business, he knows people, I don't think he'd break 95 on an IQ test. I'd give anything for half the knowledge he possesses. On the flip side, we have an accountant with a masters in accounting and another degree in engineering. One of the most brilliant ladies I've ever met. Pure knowledge though...no. Nada. Nothing. You can make the argument that intelligent people seek out knowledge, but in the real world, I just don't always find that to be the case. I can almost see intelligence as handicapping knowledge. I'll get laughed out of a company if I bid a contract by saying "I scored a 170 on the LSAT, and have an IQ of 138". That's why we send the other guy. Maybe I'm just basing it on the scope of success in the business world, but I just can't imagine that people like people like Bloomberg or Branson or Larry Page are that much more intelligent than you and I, I do believe, however, that they are extremely knowledgeable. Maybe it's just a definition conflict on the word "intelligent". Maybe I'm just looking too literal in a measurable sense.
