Brain Scans Show Why Psychopaths Don’t Feel Your Pain

psychopathsAmong other traits, psychopaths feel a lack of empathy when other people are in pain, and brain scans now reveal why that is.

Psychopathy is a personality disorder marked by callousness, manipulation, sensation seeking and antisocial behaviors. About 23 percent of people in prison are psychopaths, compared with about 1 percent of people in the general population.

In this study, researchers used functional MRI to observe brain activity in 121 inmates at a medium-security prison in the United States who were divided into three groups based on the levels of their psychopathy: high, moderate or low.

The participants were shown pictures of physical pain, such as a finger caught in a door or a toe trapped under a heavy object. They were first asked to imagine that these accidents happened to themselves and then to imagine that they happened to others.

When highly psychopathic inmates imagined themselves in these painful situations, they showed higher-than-normal activity in certain brain regions involved in empathy for pain. But these regions failed to become active when they imagined others in pain.

Moreover, when imagining other people in pain, highly psychopathic inmates showed increased activity in a brain area known to be involved in pleasure, according to the study, which was published Sept. 24 in the journalFrontiers in Human Neuroscience.

The findings may help lead to new treatment approaches for psychopaths, the researchers said in a journal news release.

Passing the “not a psychopath” test should be mandatory for employment in any position where a worker has significant influence over the lives of others. How many politicians would fail this test? Dentists? Jailers? Police? Soldiers? Well, not to insult people who join the military to protect others, combat soldiering may be one of the best jobs for someone with a psychopath brain. In fact I would not be surprised if the training and/or drugs soldiers are given encourages a lack of empathy. Would dehumanization of the enemy, learning to think of them as dirty barbaric animals, for instance, change a person to be more psychopathic?

    so we keep spending billions to have psychopaths
    help other country’s in the name of freedom, justice
    and democracy
    somehow that doesn’t make a lot of sense to me
