What do we mean by the words "normal" and "abnormal" as they apply to the mental and emotional states and behaviors of human beings? Can those words be sensibly used at all, given their tremendous baggage, their built-in biases and the general confusion they create?

Mr. Ronson's talk was not all shivers. He comforted me when he described a man that wanted to plead insanity for a crime, so he started acting like a psychopath.

By the way, psychopaths in the U.S. rarely use the NGRI (Not Guilty By Reason of Insanity) defense because they know it will deliver more time inside than going to prison. Are our psychopaths smarter?

We are spending tens of billions of dollars plying the worried well with unnecessary and expensive drugs; while at the very same time ignoring the desperate needs of those who really could benefit from psychiatric diagnosis and treatment.

Whether or not psychopathy is a valid category of mental illness doesn't have much of a bearing on how fascinating our desire to categorize psychopaths is as a cultural tendency.
