@brightflashes Psychopathy is a field of study and a condition which happens on a continuum, i.e. a spectrum. Psychopathy is split into two factors:
Factor 1 Psychopathy (Classic Psychopathy) which is mainly Interpersonal and includes symptoms like: Cold Heartedness, Low emotionality such as fearlessness, shallow emotions, Callousness, Superficial Charm, Grandiosity and Pathological Lying.
Factor 2 Psychopathy (AKA Sociopathy) is mainly Affective and Behavioral. Symptoms are: Antisocial tendencies, Impulsivity, unstable emotions, Parasytic lifestyle, irresponsibility, lack of empathy.
EDIT: A lot of INTJs including myself score high on Factor 1 Psychopathy on that test, but what it is measuring is Sub-clinical Psychopathy, not Clinical Psychopathy, I believe the test itself stated that a score of 97% or above would indicate Clinical Psychopathy. Scoring high on Factor 1 Psychopathy has a lot less meaning than scoring high on factor 2 psychopathy because Factor 1 Psychopathy is something an individual is born with via genetics. Factor 1 Psychopathy is essentially just lack of brain Structure which renders subjects incapable of experiencing many emotions. So yeah, INTJs may have "Psychopathic tendencies" like many other Thinking types, but that doesn't mean anything.
EDIT 2: This is the test I spoke of
