So how many psychopaths are in your life? Writing for the Telegraph, Tom Chivers says, “We think of psychopaths as killers, alien, outside society. But, says the scientist who has spent his life studying them, you could have one for a colleague, a friend – or a spouse”:
There are a few things we take for granted in social interactions with people. We presume that we see the world in roughly the same way, that we all know certain basic facts, that words mean the same things to you as they do to me. And we assume that we have pretty similar ideas of right and wrong.
But for a small – but not that small – subset of the population, things are very different. These people lack remorse and empathy and feel emotion only shallowly. In extreme cases, they might not care whether you live or die. These people are called psychopaths. Some of them are violent criminals, murderers. But by no means all.
Professor Robert Hare is a criminal psychologist, and the creator of the PCL-R, a psychological assessment used to determine whether someone is a psychopath. For decades, he has studied people with psychopathy, and worked with them, in prisons and elsewhere. “It stuns me, as much as it did when I started 40 years ago, that it is possible to have people who are so emotionally disconnected that they can function as if other people are objects to be manipulated and destroyed without any concern,” he says.
Our understanding of the brain is still in its infancy, and it’s not so many decades since psychological disorders were seen as character failings. Slowly we are learning to think of mental illnesses as illnesses, like kidney disease or liver failure, and developmental disorders, such as autism, in a similar way. Psychopathy challenges this view. “A high-scoring psychopath views the world in a very different way,” says Hare. “It’s like colour-blind people trying to understand the colour red, but in this case ‘red’ is other people’s emotions.”
At heart, Hare’s test is simple: a list of 20 criteria, each given a score of 0 (if it doesn’t apply to the person), 1 (if it partially applies) or 2 (if it fully applies). The list in full is: glibness and superficial charm, grandiose sense of self-worth, pathological lying, cunning/manipulative, lack of remorse, emotional shallowness, callousness and lack of empathy, unwillingness to accept responsibility for actions, a tendency to boredom, a parasitic lifestyle, a lack of realistic long-term goals, impulsivity, irresponsibility, lack of behavioural control, behavioural problems in early life, juvenile delinquency, criminal versatility, a history of “revocation of conditional release” (ie broken parole), multiple marriages, and promiscuous sexual behaviour. A pure, prototypical psychopath would score 40…
