Your reaction to PAIN could reveal if you're a psychopath, scientists say

Whether you shrug off bruises with ease or find that a stubbed toe knocks you out for a week, each of us has our own unique reaction to pain. But scientists now say that being able to grin and bear it could be a worrying sign of a dark personality. According to scientists from Radboud University, people who can handle greater levels of pain are more likely to be psychopaths. The study found that people with elevated levels of psychopathy are not only more resistant to pain but less able to learn from painful experiences. Researchers believe that this could be an important part of why people with these traits fail to learn from negative consequences.
