Here’s A List Of The Most, And Least, Psychopathic States In America, According To Science

Have you ever wondered which state has the highest (and lowest) prevalence of psychopaths? A group of researchers led by economist Ryan Murphy at Southern Methodist University did and so they gathered data from a previous state-level study on the Big Five personality traits – which was based on personality samples of almost 1.6 million people – to estimate psychopathy prevalence in each of the 48 contiguous states and the District of Columbia (Washington, D.C.). The study got its countdown by looking at the prevalence of certain traits in the Big Five model of personality.

First off, how can you identify a psychopath? Well, psychopathy, in general, is difficult to define precisely. The authors cautioned that their measurements were indirect but research does point out that psychopathic tendencies have been found to be more common in:

  • Men
  • Younger people
  • Professions such as a CEO, lawyer, media worker, salesperson, surgeon, journalist, police officer, clergy person, chef, and civil servant.

With that being said, it makes sense that the highest prevalence of psychopathy, compared to other areas, ended up being the District of Columbia.

Washington D.C. The capital of the psychopathsThe researchers wrote:

The presence of psychopaths in [the] District of Columbia is consistent with the conjecture … that psychopaths are likely to be effective in the political sphere. The District of Columbia is measured to be far more psychopathic than any individual state in the country, a fact that can be readily explained either by its very high population density or by the type of person who may be drawn to a literal seat of power.

Psychopathic traits are found most in Washington DC among politicians, lawyers and civil servantsToday, the leading diagnostic tool used by psychologists to measure psychopathy is the Hare Psychopathy Checklist-Revised (PCL-R), which measures traits such as pathological lying, impulsivity, parasitic lifestyle and lack of remorse or guilt. Another more indirect way to measure psychopathy is the triarchic model of psychopathy, which says the disorder stems from a combination of the personality traits disinhibition, boldness, and meanness. The latter is what the researchers used in this study. They used that triarchic definition of psychopathy but mapped it onto the Big Five model of personality, which includes the traits conscientiousness, openness to experience, neuroticism, extraversion, and agreeableness.

These traits are used by researchers to help explain the psychological motivations behind people’s behavior as they may also correspond to what makes people psychopaths. “Boldness corresponds to low neuroticism and high extraversion, meanness corresponds to low agreeableness, and disinhibition corresponds to low conscientiousness,” the researchers wrote. They also compared the Big Five data to four variables that relate to psychopathy: homicide rate, violent crime rate, property crime rate and percentage of residents living in an urban area.

Overall, psychopathy was primarily clustered in the Northeast, with Maine as the most psychopathic state, and in urban areas. On the other hand, people in rural areas showed to be less psychopathic. In general, psychopathy lies on a spectrum. The reality is that a very small percentage of individuals in any given state may actually be true psychopaths, according to the study. Furthermore, according to the Hare checklist, about 1% of the general population qualifies as psychopathic.

The researchers wrote:

The meaningfulness of the results found here is contingent on both the translation of Big Five personality traits into psychopathy and that psychopathy is something that can be conceptualized as a statistical aggregate across people. And if the estimates are conceptually meaningful, the question remains of whether the size of the differences across regions is practically significant. The weak relationships found in the data can themselves be interpreted as support for skepticism, but whether that interpretation is correct requires further research beyond the scope of the presentation of this methodology and results.

  2. Connecticut
