Another myth busted by science.
“Just about every claim made about psychopathy follows the same path. It begins with one or two studies that find tentative evidence to support some common claim. But a few years later, there is a torrent of studies that either fail to corroborate earlier results or straightforwardly falsify them. This trajectory has held for other claims, such as that psychopathic persons are extraordinarily dangerous, that they have impaired impulse control, that they are unresponsive to cognitive behavioural therapy, that the construct may have genetic biomarkers, or that psychopathy is associated with structural and functional brain abnormalities. Name something you’ve heard about psychopaths, and researchers will show you that it’s little more than a dubious speculation. Why has it proven so difficult for experimental psychologists to corroborate the idea of the psychopath?”
