Most extraverted and introverted U.S. states
According to Barry Smith, director of the Laboratories of Human Psychophysiology at the University of Maryland, ambiverts make up 68% of the population.
That may seem astonishing for some since Americans are thought to be very extroverted compared to Europeans, but the truth is that the culture really values extroversion over introversion. However, the value of extroversion over introversion doesn’t make extroversion more dominant. It just pressures people who find themselves on the introversion side of the spectrum to behave more extroverted, while true extroverts get positive reinforcement from the American culture that their temperament is the default.
The results from two randomized samples reveal that half of the U.S. population is introverted, or at least falls along the introvert side of the spectrum (50.2% of the U.S. population is slightly more introverted). The map below shows extraversion and introversion in the United States according to the NERIS Analytics data.
