The socialized psychopath can appear extremely charming. You have to know them really well and have a fair amount of insight yourself to spot that they always and only ever do what suits them. As long as they are getting their own way, they can be as charming as you could wish, and the most delightful company. But they will lie at the drop of a hat, without the slightest twinge of anxiety or guilt (so the old ‘lie detector’ polygraph test wouldn’t be likely to catch them out). They will use other people for their own ends without the smallest concern – treating them as no more than chess pieces in their ‘game’. They have no sense of guilt or remorse and will always be able to come up with plausible rationalizations for their behavior which allow them to lay the blame for any subsequent disaster on other people. And, of course, once chess pieces have served their purpose, there is no reason why they should not be discarded.
Is it surprising that politics and show business are thought to have more than their fair share of socialized psychopaths?
