Looking for a place to live is one case where the difference between group rationality and individual rationality is really important. I would not want to live among otherwise nearly perfect intellectuals who nonetheless had a weak grasp of game theory, a strong distrust of markets, and misanthropic attitudes. No one would ever get anything done.
It's probably not as simple as looking up a demographic stat.
Are certain areas of the world, specifically within the United States, more or less rational than others? If so, which ones and why? I am trying to determine what parts of the country would be ideal for me to live in the future and any help would be greatly appreciated.
