Psychopaths and the ‘like attracts like’ hypothesis
Some psychologists like Susan Krauss Whitbourne believes that the reputation psychopaths get from regular people could be a symptom of the “like causes like” phenomenon. Additionally this could be responsible for the inverse. She states:
People who themselves score high on measures of psychopathy should be far less likely, if at all, to stigmatize those who share their personality traits.
It’s generally thought that, in an ironic way, there is actually an empathetic relationship between two psychopaths.
