This looks interesting:
Quote:
Dr. Hare has published numerous articles and book chapters on psychopathy,
as well as two books: Psychopathy: Theory and Research (1970) and Without
Conscience: The Disturbing World of the Psychopaths Among Us (1993,
reissued 1999). He addresses international audiences on every facet of
psychopathy, from personality assessment to risk factors to psychopaths
among us. While they may appear to be normal members of society, they're
anything but. In fact, Hare believes, they are society's most destructive
and dangerous type of person. If it's true that psychopaths make up one
percent of the population, as he estimates, then we need to pay attention.
