In Western culture, particularly North America, a lot of rules are descriptors for sociopathy: a general acceptance of lying as long as you win, an attitude of "me first," an attitude that what it looks like is more important than what it is. This makes it much easier for a sociopath to be camouflaged in our culture.

Sociopathy is the inability to process emotional experience, including love and caring, except when such experience can be calculated as a coldly intellectual task.

Sociopaths differ fairly dramatically in how their brains react to emotional words. An emotional word is love, hate, anger, mom, death, anything that we associate with an emotional reaction. We are wired to process those words more readily than neutral, nonemotional words. We are very emotional creatures. But sociopaths listen as evenly to emotional words as they do to lamp or book - there's no neurological difference.

The central trait of sociopathy is a complete lack of conscience, which is very difficult for most people to get their heads around, because those of us who do have a conscience can't really imagine what it would be like if we didn't. Most people think that deep down everybody has a conscience, and it turns out that's just not true.

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.

The bottom line for most people who are normal is their need for other people. Even the greedy ones have this need - as long as they're not sociopathic. They may be very misguided and unhappy and do bad things and so forth, but in general if you look down deep, you find that these people are mainly concerned with other people and what other people think of them.

We are all a little crazy.
