Quoting from Wikipedia: 'Additionally, studies suggest inverse relationships between psychopathy and intelligence, including with regards to verbal IQ' (but later it's stated that such correlation is not unanimously accepted).
I think we mostly are in agreement; I think the impulsive and antisocial tendencies of the psychopath are often self defeating and only the very intelligent navigate life successfully. We end up having a selection bias because we are likely to cross paths only with the latter subtype, so we end up believing that all psychopaths are superintelligent and verbally dazzling, while probably the majority of them is badly dull.
