Here are the U.S. states with the highest prevalence of psychopaths
A recent study used data from the Big Five personality to estimate psychopathy prevalence in the 48 contiguous states and Washington, D.C.
- The study estimated psychopathy prevalence by looking at the prevalence of certain traits in the Big Five model of personality.
- The District of Columbia had the highest prevalence of psychopathy, compared to other areas.
- The authors cautioned that their measurements were indirect, and that psychopathy in general is difficult to define precisely.
A new study estimated the prevalence of psychopathy in the 48 contiguous states and the District of Columbia.
How can you identify psychopaths? It's difficult, but research provides a few clues, such as that psychopathic tendencies are more common in:
- Younger people
- Professions such as CEOs, lawyers and politicians
Psychologists have used different diagnostic tools to measure psychopathy over the decades. Today, the leading tool is the Hare Psychopathy Checklist-Revised (PCL-R), which measures traits such as pathological lying, impulsivity, parasitic lifestyle and lack of remorse or guilt. But psychopathy can be measured in other, more indirect ways, too.
One example is the triarchic model of psychopathy, which says the disorder stems from a combination of the personality traits disinhibition, boldness and meanness. In the recent study, the researchers used that triarchic definition of psychopathy, but mapped it onto the Big Five model of personality, which includes the traits conscientiousness, openness, neuroticism, extraversion and agreeableness.
To measure psychopathy across the 48 contiguous states and Washington, D.C., the researchers used state-level Big Five data from a previous study. The results consistently showed that people in rural areas tended to be less psychopathic, while urban areas were more psychopathic. Scoring highest in psychopathy, perhaps unsurprisingly, was the District of Columbia.
"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," the researchers wrote.
Regionally, psychopathy was clustered in the Northeast, with Maine as the most psychopathic state. Some psychologists have described the Northeast as "Temperamental and Uninhibited." In terms of the Big Five personality traits, the researchers wrote that this translates to "low extraversion, very low agreeableness and conscientiousness, very high neuroticism, and moderately high openness."
The researchers 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. Only the share of residents living in an urban area had a significant relationship with the personality data.
Ultimately, the researchers cautioned that their methodology was indirect, and that "some amount of noise will inevitably be captured in the results."
"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," they wrote. "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."
What's more, psychopathy lies on a spectrum. The researchers note that "a very small percentage of individuals in any given state may actually be true psychopaths." According to the Hare checklist, about 1 percent of the general population qualifies as psychopathic.
Here's how the recent study ranked the 48 contiguous states:
3. New York
8. New Jersey
12. Rhode Island
22. South Dakota
26. New Hampshire
27. North Dakota
40. New Mexico
41. West Virginia
44. South Carolina
48. North Carolina

Construction of the $500 billion dollar tech city-state of the future is moving ahead.
- The futuristic megacity Neom is being built in Saudi Arabia.
- The city will be fully automated, leading in health, education and quality of life.
- It will feature an artificial moon, cloud seeding, robotic gladiators and flying taxis.

Are we genetically inclined for superstition or just fearful of the truth?
- From secret societies to faked moon landings, one thing that humanity seems to have an endless supply of is conspiracy theories. In this compilation, physicist Michio Kaku, science communicator Bill Nye, psychologist Sarah Rose Cavanagh, skeptic Michael Shermer, and actor and playwright John Cameron Mitchell consider the nature of truth and why some groups believe the things they do.
- "I think there's a gene for superstition, a gene for hearsay, a gene for magic, a gene for magical thinking," argues Kaku. The theoretical physicist says that science goes against "natural thinking," and that the superstition gene persists because, one out of ten times, it actually worked and saved us.
- Other theories shared include the idea of cognitive dissonance, the dangerous power of fear to inhibit critical thinking, and Hollywood's romanticization of conspiracies. Because conspiracy theories are so diverse and multifaceted, combating them has not been an easy task for science.
A growing body of research suggests COVID-19 can cause serious neurological problems.
- The new study seeks to track the health of 50,000 people who have tested positive for COVID-19.
- The study aims to explore whether the disease causes cognitive impairment and other conditions.
- Recent research suggests that COVID-19 can, directly or indirectly, cause brain dysfunction, strokes, nerve damage and other neurological problems.
