The study looked at how psychopathic traits can influence prejudiced attitudes in a large European sample. They found that certain psychopathic traits, like being manipulative and lacking empathy, were linked to holding prejudiced views towards minorities and refugees. These traits also influenced beliefs in social dominance and right-wing authoritarianism, which are related to prejudice. Overall, the research suggests that there is a connection between psychopathic tendencies, social attitudes, and prejudiced attitudes in European populations.
