most recent article debunking sociopath myths:
I think she's much closer to the mark, ironically by not really trying too hard to pin down exactly what psychopathy is. As I recall her main line of attack is focused on the current conception, the Hare model. The two areas that I think are weakest with the current model are where she focuses, namely the idea that psychopathy is totally untreatable, as well as including criminality as central to the disorder. Both of these assumptions are based on faulty data. For a laugh, check out the methodology of the first study that concluded psychopaths weren't helped by therapy. They put a bunch of violent convicts together naked in a room and gave them a ton of LSD. What a shocker that didn't turn out well.
Skeem's revised model is more like the lack of a model. Rather than claiming to have an objective definition she argues that psychopathy should be understood as a nebulous constellation of personality traits. I think this is a much more realistic approach because people are always going to be more complicated than a checklist. The more I read about the subject the more I question if psychopathy truly exists. "Psychopath" is something that you call an other person. Anyone who claims that title for themselves without any reservations probably wants to see themselves that way, for whatever reason.
There's another really interesting section you may want to check out that probably would be better as another post than an addendum to the first. The section is called "Does Secondary Psychopathy Exist?" and I think poses an important question. I don't think that high anxiety, highly emotionally reactive people are psychopaths, even if they may exhibit similar behavior.
For what it is worth, I completely agree with that last part. These people who feel overwhelmed by their emotions -- their emotions are the root of their impulsivity -- that just sounds like something too different to include in our general conception of what is a psychopath, even if the outward manifestations of it are similar.
