Are You a Psychopath?

The Hare Psychopathy Checklist-Revised (PCL-R), published by Multi-Health Systems, is used worldwide and provides clinicians and researchers with a way of distinguishing psychopathic people from those who merely break the rules.

What follows is a summary of key traits and behaviours of psychopathy. The list is adapted from my book Without Conscience (published by Guilford Press). Do not use these features to diagnose yourself or others. A formal assessment requires professional qualifications, access to the PCL-R scoring manual, and the integration of a considerable amount of information from different sources, contexts, and areas of a person’s life. That is, the features are part of the person’s personality and typical interactions with others, and not descriptive of functioning in only one or two domains, such as family or business.

Each feature can vary from absent to extreme. Some people may have a few features (e.g., impulsive, or glib, or cold and unfeeling) but this does not make them psychopathic. Psychopathy is viewed as a dimensional clinical construct in which people differ in degree rather than in kind. Most people fall at the very low end of this dimension. Some people are higher up the dimension, and although they may be problematic or distressing in various ways to those around them, they would not be considered to be psychopathic. Researchers and clinicians define individuals as psychopathic if they fall at the upper end of the dimension; that is, they have the majority the defining features in an extreme form over much of the lifespan. Only about one percent of the general population meets these conditions.

If you suspect that someone you know conforms to the profile described here, and if it is important for you to have an expert opinion, you should obtain the services of a registered forensic psychologist or psychiatrist.

Glib and Superficial

Psychopaths are often voluble and verbally facile. They can be amusing and entertaining conversationalists, ready with a clever comeback, and are able to tell unlikely but convincing stories that cast themselves in a good light.

Egocentric and Grandiose

Psychopaths have a narcissistic and grossly inflated view of their own self-worth and importance, a truly astounding egocentricity and sense of entitlement, and see themselves as the centre of the universe, justified in living according to their own rules.

Lack of Remorse or Guilt

Psychopaths show a stunning lack of concern for the effects their actions have on others, no matter how devastating these might be. They may appear completely forthright about the matter, calmly stating that they have no sense of guilt, are not sorry for the ensuing pain, and that there is no reason now to be concerned.

Lack of Empathy

Many of the characteristics displayed by psychopaths are closely associated with a profound lack of empathy and inability to construct a mental and emotional “facsimile” of another person. They seem completely unable to “get into the skin” of others, except in a purely intellectual sense.


6 / 11

Shallow Emotions

Psychopaths seem to suffer a kind of emotional poverty that limits the range and depth of their feelings. At times they appear to be cold and unemotional while nevertheless being prone to dramatic, shallow, and short-lived displays of feeling. Careful observers are left with the impression they are playacting and little is going on below the surface.



7 / 11

Poor Behaviour Controls

Besides being impulsive, psychopaths are highly reactive to perceived insults or slights. Most of us have powerful inhibitory controls over our behaviour; even if we would like to respond aggressively we are usually able to “keep the lid on.” In psychopaths, these inhibitory controls are weak, and the slightest provocation is sufficient to overcome them. But, their actions have a “cold” and focused quality about them, and return to “normal” is quick.

A Need for Excitement

Psychopaths have an ongoing and excessive need for excitement-they long to live in the fast lane or “on the edge,” where the action is. In many cases the action involves the breaking of rules.

Lack of Responsibility

Obligations and commitments mean nothing to psychopaths. Their good intentions-“I’ll never cheat on you again”-are promises written on the wind. Their performance on the job is erratic, with frequent absences, misuse of company resources, violations of company policy, and general untrustworthiness. They do not honour formal or implied commitments to people, organizations, or principles.

Early Behaviour Problems

Most psychopaths begin to exhibit serious behavioural problems at an early age. These might include persistent lying, cheating, theft, arson, truancy, substance abuse, vandalism, and/or precocious sexuality. Because many children exhibit some of these behaviours at one time or another, it is important to emphasize that the psychopath’s history of such behaviours is more extensive and serious than most.


11 / 11

Adult Antisocial Behaviour

Psychopaths see the rules and expectations of society as inconvenient and unreasonable impediments to their own behavioural expression. They make their own rules. Antisocial behaviour may consist of phoney stock promotions, questionable business practices, partner or child abuse, and so forth. Others do things that are not necessarily illegal but are nevertheless unethical, immoral, or harmful to others: cheating on a partner, emotional abuse, bullying, to name but a few.
