In northwest Alaska, kunlangeta "might be applied to a man who, for example, repeatedly lies and cheats and steals things and does not go hunting, and, when the other men are out of the village, takes sexual advantage of many women." The Inuits tacitly assume that kunlangeta is irremediable. And so, according to Murphy, the traditional Inuit approach to such a man was to insist he go hunting, and then, in the absence of witnesses, push him off the edge of the ice.

The physical basis for sociopathy is approximately 50 percent inheritable, which sounds more dramatic than it probably is, because most personality characteristics that psychologists test for and study the genetics of are about 50 percent inheritable. Introversion, extroversion, it turns out that they're about 50 percent inheritable, which means that somehow sociopathy is physical, it's organic.

A part of a healthy conscience is being able to confront consciencelessness. When you teach your daughter, explicitly or by passive rejection, that she must ignore her outrage, that she must be kind and accepting to the point of not defending herself or other people, that she must not rock the boat for any reason, you are NOT strengthening her posocial sense, you are damaging it-and the first person she will stop protecting is herself.

I was once doing a book signing and a man came up to me and said that he gave classes to people who'd been convicted of drunken driving twice. He said he felt that nearly all of those people were what I was describing as sociopathic. Which makes a great deal of sense to me. We always talk about how could you possibly, knowing that you're drunk, get behind the wheel of a car again and do that? Well, you could if you didn't give a half a damn what happened.

I am always impressed by the fact that even the tiniest amount of being listened to, the barest suggestion of the possibility of kind treatment, can bring such an immediate rush of emotion. I think this is because we are almost never really listened to. In my work as a psychologist, I am reminded every day of how infrequently we are heard, any of us, or our actions even marginally understood. And one of the ironies of my "listening profession" is its lesson that, in many ways, each of us ultimately remains a mystery to everyone else.

To learn to be charming is fairly easy - you can teach somebody to be charming and to learn human emotions - or to learn the behaviors that go with human emotions. A sociopath, a smart one, will study the way we emote, and will learn how to do that quite effectively.

Sociopaths love power. They love winning. If you take loving kindness out of the human brain, there's not much left except the will to win.
