Few Surprises on this List.

This kind of reminds me of the old debunked presidential IQ thing that was floating around the internet a few years ago. http://www.snopes.com/inboxer/hoaxes/presiq.asp

So I looked into what the scale they are using was and it's called the 'Flesch–Kincaid readability tests' which doesn't have anything at all to do with intelligence, but rather how difficult something is to read. Basically the only thing that it shows is that modern presidents are easier to read and understand than older ones. This probably has to do with the fact they need to appeal to a broader electorate than in the past and has very little to do with intelligence. In fact that you can make your ideas easier to disseminate could very well be a sign of intelligence.
