A study by a Texas university looked at which states in the United States are the most psychopathic.

The study by Southern Methodist University professor Ryan Murphy found that Connecticut ranks No. 1 in the U.S. as the most psychopathic state.

Murphy says that the study "constructs a cross-section of the 'Big Five' personality traits and demonstrates their relationship with outcomes variables for the continental United States… When these two findings are combined, a state-level estimate of psychopathy is produced."

California ranks No. 2, followed by New Jersey.

The lease psychopathic states were Tennessee, Vermont and West Virginia, according to the study.
