US Can Be Regionally Divided By Residents' Personality Types: People Of Similar Temperaments Live In Same Parts Of US

From "Divided we stand: US regions exhibit distinct personalities" on ScienceBlog:

Americans with similar temperaments are so likely to live in the same areas that a map of the country can be divided into regions with distinct personalities, according to new research published by the American Psychological Association.

People in the north-central Great Plains and the South tend to be conventional and friendly, those in the Western and Eastern seaboards lean toward being mostly relaxed and creative, while New Englanders and Mid-Atlantic residents are prone to being more temperamental and uninhibited, according to a study published online by APA’s Journal of Personality and Social Psychology.

"This analysis challenges the standard methods of dividing up the country on the basis of economic factors, voting patterns, cultural stereotypes or geography that appear to have become ingrained in the way people think about the United States," said lead author Peter J. Rentfrow, PhD, of the University of Cambridge. "At the same time, it reinforces some of the traditional beliefs that some areas of the country are friendlier than others, while some are more creative."
