The 10 professions with the most psychopaths

Psychopaths are difficult to spot most of the time. They're not the "Jack the Ripper" caricatures you see in films or read about in books. Often, psychopaths appear normal, which makes them hard to identify.

In the Diagnostic and Statistical Manual of Mental Disorders, or DSM-5, someone with a psychopathic personality type is defined as having an inflated, grandiose sense of themself, and a knack for manipulating other people. But a diagnosis is rarely simple.

One thing psychopaths tend to have in common is the careers they go for. For example, you're likely to find a lot of them in leadership positions because of their ruthlessness, charisma, and fearlessness. They're very good at making snap decisions, but not so good at the empathetic professions like nursing or therapy.

Kevin Dutton, a British psychologist and writer, specialises in the study of psychopathy. In his book "The Wisdom of Psychopaths: What Saints, Spies, and Serial Killers Can Teach Us About Success," he made a list of the types of jobs that attract the most psychopaths.
