Certain regional stereotypes have long since become cliches: The stressed-out New Yorker. The laid-back Californian. But the conscientious Floridian? The neurotic Kentuckian?
You bet -- at least, according to new research on the geography of personality. Based on more than 600,000 questionnaires and published in the journal Perspectives on Psychological Science, the study maps regional clusters of personality traits, then overlays state-by-state data on crime, health and economic development in search of correlations.
Even after controlling for variables such as race, income and education levels, a state's dominant personality turns out to be strongly linked to certain outcomes. Amiable states, like Minnesota, tend to be lower in crime. Dutiful states -- an eclectic bunch that includes New Mexico, North Carolina and Utah -- produce a disproportionate share of mathematicians. States that rank high in openness to new ideas are quite creative, as measured by per-capita patent production. But they're also high-crime and a bit aloof. Apparently, Californians don't much like socializing, the research suggests.
As for high-anxiety states, that group includes not just Type A New York and New Jersey, but also states stressed by poverty, such as West Virginia and Mississippi. As a group, these neurotic states tend to have higher rates of heart disease and lower life expectancy.
Lead researcher Peter Jason Rentfrow, lecturer at the University of Cambridge in England, said he was startled to find such correlations. "That just blew me away," he said.
Psychologists unaffiliated with the study say it's intriguing but limited. There's no way to unravel the chicken-and-egg question: Do states tend to nurture specific personalities because of their histories, cultures, even climates? Or do Americans, seeking kindred spirits, migrate to the states where they feel at home? Maybe both forces are at work -- but in what balance?
Another issue: The personality maps may reinforce stereotypes and tempt us to draw overly simplistic conclusions, said Toni Schmader, a psychologist at the University of Arizona. Knowing Arizona ranks low in neuroticism, Ms. Schmader said, she might conclude that sunny weather makes for sunny dispositions. But if the data had turned out the other way, the sun could just as easily be blamed for high neuroticism -- for driving Arizonans stir crazy by keeping them cooped up in air conditioning.
"We tend to reject information that doesn't agree with our stereotypes," Ms. Schmader said.
