The NY times had an article about psychopaths, including a reference to a "psychopathy checklist"
Here's the article:

Wonder if this test will be added as part of school curricula??
Here's some excerpts from the NY Times article referenced above
Researchers have found that some people who commit violent crimes are much more likely than others to kill or maim again, and one way they measure this potential is with a structured examination called the psychopathy checklist.
As part of an extensive, in-depth interview, a trained examiner rates the offender on a 20-item personality test. The items include glibness and superficial charm, grandiose self-worth, pathological lying, proneness to boredom and emotional vacuity. The subjects earn zero points if the description is not applicable, two points if it is highly applicable, and one if it is somewhat or sometimes true.
The psychologist who devised the checklist, Dr. Robert Hare, a professor emeritus at the University of British Columbia in Vancouver, said that average total scores varied from below five in the general population to the low 20's in prison populations, to a range of 30 to 40 - highly psychopathic - in predatory killers. In a series of studies, criminologists have found that people who score in the high range are two to four times as likely as other prisoners to commit another crime when released. More than 90 percent of the men and a few women at the top of Dr. Stone's hierarchy qualify as psychopaths.
In recent years, neuroscientists have found evidence that psychopathy scores reflect physical differences in brain function. Last April, Canadian and American researchers reported in a brain-imaging study that psychopaths processed certain abstract words - grace, future, power, for example - differently from nonpsychopaths.
No one knows how significant these differences are, or whether they are a result of genetic or social factors. Broken homes and childhood trauma are common among brutal killers; so is malignant narcissism, a personality type characterized not only by grandiosity but by fantasies of unlimited power and success, a deep sense of entitlement, and a need for excessive admiration.
Checklists, scales, and other psychological exams are not blood tests, however, and their use in support of a concept as loaded as evil could backfire, many psychiatrists say. Not all violent predators are psychopaths, for one thing, nor are most psychopaths violent criminals. And to suggest that psychopathy or some other profile is a reliable measure of evil, they say, would be irresponsible and ultimately jeopardize the credibility of the profession
The doctors who argue that evil has a place in forensics are well aware of these risks, but say that in some cases they are worth taking. They say it is possible - necessary, in fact, to understand many predatory killers - to hold inside one's head many disparate dimensions: that the person in question may be narcissistic, perhaps abused by a parent, or even charming, affectionate and intelligent, but also in some sense evil. While the term may not be appropriate for use in a courtroom or a clinical diagnosis, they say, it is an element of human nature that should not be ignored.
