Lack of empathy for distress helps explain why psychopaths have no difficulty in engaging in premeditated hurtful and antisocial behaviour. But it does not fully explain the behavioural profile of individuals with psychopathy. Why do psychopaths often make foolish life choices that are likely to result in serious repercussions to them? Why don’t they worry about other people’s happiness and establish loving relationships? ‘Explaining impulsivity and failure to behave prosocially’ considers why individuals with psychopathy make poor, impulsive decisions, even if there is a strong likelihood of reprisal and why psychopaths are able to get excited about material rewards, but do not find social relationships rewarding and motivating in the same way as the rest of us do.
