One point the article should have made, IMHO, is that for any kind of personality disorder, it is a continuum, not a discrete true-or-false distinction. A medical doctor can clearly and unambiguously diagnose whether or not you have, say, Type-1-diabetes or a broken leg, there is no wiggle-room, it is not open to interpretation. With personality disorders, the definition is usually a list of symptoms of which a person has to show at least a certain number (e.g. 5 out of 9) to "qualify". But a person that shows, say, 4 out of 9 symptoms of Antisocial Personality Disorder, would still be very unpleasant to be around, even if he or she is not a sociopath from a clinical point of view. (I am making the numbers up to make a point - the actual length of the list and the number of symptoms one has to show for APD is probably different, but not radically so.)
