To ask such questions, you must first define a scalar measure of "rationality" that can be compared between people. I don't find the choice of this measure at all obvious, or even that it can be meaningfully defined.

Not necessarily; there just has to be an ordering. Clearly people's rationality can be compared, as extreme cases illustrate: Eliezer Yudkowsky is more rational than Kent Hovind, for example.
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.
