According to KELO, the website Truit has pegged South Dakota as the most neurotic of the all the states. It also believes we are the 3rd most introverted, and the most focused, life-organizationally speaking, whatever the hell that means. Finally, along with North Dakota (aka "Dakota"), the Rushmore State is considered to be the land of the "Friendly Conservative." So, according to one source, we are known as "open, warm, and straightforward," as well as the most likely to go postal on your ass.
Illinois is claimed to be the most competitive state, along with the most flexible in that life-organization category, and that it's citizens are most likely to think in concrete terms rather than in the abstract.
I'm sure there's a lot more, but I couldn't find the original source at Truity.com. So, anybody agree or disagree with what we see here?
