The following were taken from an
article on Dr. Robert Hare, psychopathy expert.
History of the term psychopath:
The condition itself has been recognized for centuries, wearing evocative labels such as "madness without delirium" and "moral insanity" until the late 1800s, when "psychopath" was coined by a German clinician. But the term (and its 1930s synonym, sociopath) had always been a sort of catch-all, widely and loosely applied to criminals who seemed violent and unstable.
Why we should care about psychopaths:
Psychopathy may prove to be as important a construct in this century as IQ was in the last (and just as susceptible to abuse), because, thanks to Hare, we now understand that the great majority of psychopaths are not violent criminals and never will be. Hundreds of thousands of psychopaths live and work and prey among us.
On their inability to respond to punishment or learn from negative experiences:
For his first paper, now a classic, Hare had his subjects watch a countdown timer. When it reached zero, they got a "harmless but painful" electric shock while an electrode taped to their fingers measured perspiration. Normal people would start sweating as the countdown proceeded, nervously anticipating the shock. Psychopaths didn't sweat. They didn't fear punishment--which, presumably, also holds true outside the laboratory.
On the sociopaths' lack of familiarity with emotional language:
Hare made another intriguing discovery by observing the hand gestures (called beats) people make while speaking. Research has shown that such gestures do more than add visual emphasis to our words (many people gesture while they're on the telephone, for example); it seems they actually help our brains find words. That's why the frequency of beats increases when someone is having trouble finding words, or is speaking a second language instead of his or her mother tongue. In a 1991 paper, Hare and his colleagues reported that psychopaths, especially when talking about things they should find emotional, such as their families, produce a higher frequency of beats than normal people. It's as if emotional language is a second language--a foreign language, in effect--to the psychopath.
On the potential for abuse:
"We'll let people out [of prison] on the basis of scores on this, and we'll put them in. And we'll take children who do badly on some version of this and segregate them or something. It wasn't designed to do any of these things. The problems that politicians are trying to solve are fundamentally more complicated than the one that Bob has solved."
On using the diagnosis to argue in favor of the death penalty:
"A psychological instrument and diagnosis should not be a determinant of whether someone gets the death sentence. That's more of an ethical and political decision."
On the sociopath's level of humanity:
Are these people qualitatively different from us? "I would think yes," says Hare. "Do they form a discrete taxon or category? I would say probably--the evidence is suggesting that. But does this mean that's because they have a broken motor? I don't know. It could be a natural variation." True saints, completely selfless individuals, are rare and unnatural too, he points out, but we don't talk about their being diseased.
On the possibility of a cure:
Asked if he thinks there will ever be a cure for psychopathy--a drug, an operation--Hare steps back and examines the question. "The psychopath will say 'A cure for what?' I don't feel comfortable calling it a disease. Much of their behaviour, even the neurobiological patterns we observe, could be because they're using different strategies to get around the world. These strategies don't have to involve faulty wiring, just different wiring."
