RationalWiki's 2020 Fundraiser

There is no RationalWiki without you. We are a small non-profit with no staff – we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.

If everyone who saw this today donated $5, we would meet our goal for 2021.

Fighting pseudoscience isn't free.
We are 100% user-supported! Help and donate $5, $20 or whatever you can today with PayPal Logo.png!

A psychopath is an individual conforming to the diagnostic criteria for psychopathy, a common[1] personality disorder.

Technical definitions[edit]

Psychopaths display a lack of conscience and a certain level of superficial charm. Because of these conditions as well as being self-serving and manipulative in nature, they often do very well in both business and politics.

The technical term for psychopathy — as listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM) — is antisocial personality disorder or ASPD. The term sociopath is also often applied to psychopaths. The media and the general public often use these three terms in the following contexts:

  • "Antisocial" applies to a person who actively opposes social norms. It is often is misapplied to people (especially teens) who are introverted or have a difficult time fitting in with society. Autistic people and people with schizoid personality disorder[2] were once considered to have ASPD because they may be loners who don't fit in. This is often folly because it either fails, or more disturbingly, neglects to differentiate betwixt antisocial behavior (actively opposing social norms) and asocial behavior (passively indifferent to social norms).
  • "Sociopath" is usually applied to those diagnosed with ASPD based on behavioral traits alone.
  • "Psychopath" is usually applied to those diagnosed with ASPD based on behavioral, affective, and personality traits.

However, it should be noted that to most professional psychologists and psychiatrists, the three terms are synonymous, though some have argued that psychopathy should be a separate disorder.[3] Psychopathy is generally regarded to be a neurobiological disorder whereas Antisocial personality disorder (sociopathy) is considered to be the result of abuse or trauma, like narcissistic personality disorder which is correlated with psychopathy in the Diagnostic and Statistical Manual of Mental disorders (DSM).

Capitalism and everyday psychopaths[edit]

Psychopathy isn't limited to only criminals and can in fact be beneficial to an individual in a capitalistic society. Several researchers, such as Swiss psychiatrist Guggenbühl-Craig in his book The Emptied Soul,[4] argue capitalism is an economy which encourages psychopathy and arrogant behavior to achieve great rewards. Slyness and deception, these characteristics would be detrimental in any other economy except in capitalism. In other words, it is a great advantage to not have a conscience because it allows psychopaths to not get distracted from the great satisfaction of self-indulgence, even if it means performing acts which disadvantage others.

In Paul Zak's TED talk, Zak explores the effects of oxytocin on human morality:[5]

So who are these people who manipulate our oxytocin systems? We found, testing thousands of individuals, that five percent of the population don't release oxytocin on stimulus. So if you trust them, their brains don't release oxytocin. If there's money on the table, they keep it all. So there's a technical word for these people in my lab. We call them bastards. (Laughter) These are not people you want to have a beer with. They have many of the attributes of psychopaths.

While five percent may seem like a small amount, keep in mind the statistic says 1 out of 20 people share qualities which can be considered psychopathic.

Hare psychopathy checklist[edit]

Canadian psychologist Robert D. Hare has developed a check list of personality traits that are common to most psychopaths. The Psychopathy Checklist-Revised (PCL-R) is as follows:

  • Factor 1 — Personality "Aggressive narcissism"
    • Glibness/superficial charm
    • Grandiose sense of self-worth
    • Pathological lying
    • Cunning/manipulative
    • Lack of remorse or guilt
    • Emotionally shallow
    • Callous/lack of empathy
    • Failure to accept responsibility for own actions
  • Factor 2 — Case History "Socially Deviant Lifestyle"
    • Need for stimulation/proneness to boredom
    • Parasitic lifestyle
    • Poor behavioral control
    • Promiscuous sexual behavior
    • Lack of realistic, long-term goals
    • Impulsiveness
    • Irresponsibility
    • Juvenile delinquency
    • Early behavioral problems
    • Revocation of conditional release
  • Traits not correlated with either factor
    • Many short-term marital relationships
    • Criminal versatility[6]

Surveyors assign number values to the above traits.

  • Does not apply = 0
  • Somewhat applies = 1
  • Fully applies = 2

If a person scores more than 20 points, then yes. It's quite likely they at least have some psychopathic tendencies.
