Anti-Social Personality Disorder is just a checklist for criminality. It's a joke of a condition and should be stripped from all medical and psychological journals.
The Factor-1 criteria for Hare's Psychopathy Checklist stand up much better in terms of a "Psychopathic personality":
http://en.wikipedia.org/wiki/Hare_Psychopathy_Checklist:
Factor 1: PersonalityGlibness/superficial charm
Grandiose sense of self-worth
Pathological lying
Cunning/manipulative
Lack of remorse or guilt
Shallow affect (genuine emotion is short-lived and egocentric)
Callousness; lack of empathy
Failure to accept responsibility for own actions
Whilst it's said a psychopath will score high in factor 1 and factor 2, I'd still say that's trying to conflate criminality with personality and really criminality and personality (psychopathy vs criminality) should be considered two separate concepts entirely with merely some correlation.
I'll admit I still dislike some aspects of Factor 1. "superficial charm" is different from regular charm how exactly? Is it superficial because they aren't expressing their real feelings? But isn't that just more signs of pathological lying? And if it's superficial because it's "the tendency to be smooth, engaging, charming, slick, and verbally facile"...isn't that just called, ya know: Charm?
If someone likes you, they'll say you're charming. If they don't, they'll say you're glib. It's too subjective to take seriously as a criteria.
So yeah, some of these concepts seem stupid to me but still...it's like how is a lack of guilt any different to a lack of fear? Guilt is often just a fear you'll be caught and suffer punishment, is it not? Can anybody define a real difference between the two? A lot of the things I read, it seems like people are trying to describe something when they don't understand what they are trying to say it's different from.
The research is faulty, the concepts are broken and as such any understanding or meaning is found wanting.
