UNITED NEWS INTERNATIONAL (UNI) — A new study published Tuesday, June 12 on the Social Science Research Network ranks psychopathy by each U.S. State.

Ryan Murphy, a professor at Southern Methodist University, wrote the study using existing research that calculates the levels of five personality traits.

The traits include extraversion, agreeableness, conscientiousness, neuroticism and openness to experience.

Murphy explained the five personality traits can be linked to psychopathic traits such as boldness, disinhibition and meanness.

He stated in his paper, which is currently awaiting peer review, that “Boldness corresponds to low neuroticism and high extraversion, meanness corresponds to low agreeableness, and disinhibition corresponds to low conscientiousness.”

Connecticut won the award for the most psychopathic state in the United States, followed by California and New Jersey to round out the top three.

West Virginia, Vermont and Tennessee are among the least psychopathic states in the country.
