The Wall Street Journal has published the results of a study on personality traits across the nation. The article discusses the results and includes an interactive map (may not work in all browsers). Each state is ranked on five factors - (extraversion, agreeableness, conscientiousness, neuroticism, and openness). Since the results are aggregated by state, it fails to account for differences between city-dwellers and country-folk.

Anyway, the most interesting part of this is comparing the state of Washington to our old home state of Texas. Texas ranked close to the median for pretty much everything, while Washington was ranked as the 4th most introverted state, 5th least neurotic, and also ranked very high in openness to new ideas along with the rest of the west coast. So, for what it's worth, I guess we live in a more introverted, emotionally-stable, and open-minded state than before.
