Psychopathy (pronounced /saɪˈkɒpəθi/[1][2]) is a psychological construct that describes chronic disregard for ethical principles and antisocial behavior.[3][4] Psychopaths are characterized by their shallow affect, superficial charm, manipulativeness, lack of empathy, criminal versatility, impulsiveness, irresponsibility, poor behaviour controls, and juvenile delinquency.[5] Individuals with this disorder gain satisfaction through their antisocial behavior and lack remorse for their actions.[6][7][8]
Currently, there are no diagnostic criteria in the Diagnostic and Statistical Manual of Mental Disorders for psychopathy. Labeling a person as a psychopath involves forensic measurement, using a diagnostic tool such as the Hare Psychopathy Checklist (PCL-R). The PCL-R is widely considered the "gold standard" for assessing psychopathy. Psychopathy is most strongly correlated with DSM-IV antisocial personality disorder, and the ICD-10 antisocial personality disorder and dissocial personality disorder. However, the PCL-R criteria for identifying a psychopath are stricter than the diagnostic criteria for ASPD or DPD; psychopaths represent a subset of those with ASPD, and psychopaths' traits are more severe.[9]
Psychopathy is used as a definition in law; one example is psychopathic personality disorder as defined under the United Kingdom's Mental Health Act 1983. The term psychopathy is often confused with psychosis; for this reason, the term sociopathy is sometimes used interchangably with psychopathy.[10] It is estimated that approximately one percent of the general population are psychopaths.[11][12][13][14]

The origins of the concept of psychopathy go back to Theophrastus, a student of Aristotle, whose description of The Unscrupulous Man embodies the characteristics of psychopathy.[15][16]
In 1801, Philippe Pinel described patients who were mentally unimpaired but nonetheless engaged in impulsive and self-defeating acts. He saw them as la folie raisonnante ("insane without delirium") meaning they fully understood the irrationality of their behavior but continued with it anyway. By the turn of the century, Henry Maudsley had begun writing about the "moral imbecile", and was arguing such individuals could not be rehabilitated by the correctional system.[17]
Maudsley included the psychopath's immunity to the reformational effects of punishment, owing to their refusal to anticipate further failure, and punishment.[citation needed] In 1904, Emil Kraepelin described four types of personalities similar to antisocial personality disorder. By 1915 he had identified them as defective in either affect or volition, dividing the types further into different categories, only some of which correspond to the current descriptions of antisocial personality disorder.[18]
The Mask of Sanity by Hervey M. Cleckley, M.D., first published in 1941, is considered a seminal work and the most influential clinical description of psychopathy in the 20th century. The basic elements of psychopathy outlined by Cleckley are still relevant today.[19] The title refers to the "mask" of normality that conceals the mental disorder of the psychopathic person.[20]
Otto Kernberg believed psychopathy should fall under a spectrum of pathological narcissism, that ranged from narcissistic personality on the low end, malignant narcissism in the middle, and psychopathy at the high end.[21]
Lack of a conscience in conjunction with a weak ability to defer gratification and/or control aggressive desires, often leads to antisocial acts.
Psychopaths (and others on the pathological narcissism scale) low in social cognition are more prone to violence, occupational failure, and problems maintaining relationships. Psychopaths differ in their impulse control abilities and overall desires. Those high in the pathological narcissism scale are more equipped to succeed, but pathological narcissism does not in any way guarantee success.
In contemporary research, psychopathy has been most frequently operationalized by Dr. Robert D. Hare's Psychopathy Checklist-Revised (PCL-R). The checklist assesses both interpersonal and affective components as well as lifestyle and antisocial deficits. However, the research results cannot be easily extrapolated to the clinical diagnoses of dissocial personality disorder or antisocial personality disorder.
A sample research finding is that between 50 percent and 80 percent of prisoners in England and Wales meet the diagnostic criteria of dissocial personality disorder, but only 15 percent would be predicted to be psychopathic as measured by the PCL-R. Therefore, the findings drawn from psychopathy research have not yet been shown to be relevant as an aid to diagnosis and treatment of dissocial or antisocial personality disorders.[22]
The following findings are for research purposes only, and are not used in clinical diagnosis. These items cover the affective, interpersonal, and behavioral features. Each item is rated on a score from zero to two. The sum total determines the extent of a person's psychopathy.[9]
Factor 1: Aggressive narcissism
Factor 2: Socially deviant lifestyle
Traits not correlated with either factor
In practice, mental health professionals rarely treat psychopathic personality disorders as they are considered untreatable and no interventions have proved to be effective.[23] In England and Wales the diagnosis of dissocial personality disorder is grounds for detention in secure psychiatric hospitals under the Mental Health Act if they have committed serious crimes, but since such individuals are disruptive for other patients and not responsive to treatment this alternative to prison is not often used.[24]
Because an individual's scores may have important consequences for his or her future, the potential for harm if the test is used or administered incorrectly is considerable. The test can only be considered valid if administered by a suitably qualified and experienced clinician under controlled conditions. [25][26]
Hare wants the Diagnostic and Statistical Manual of Mental Disorders to list psychopathy as a unique disorder, saying psychopathy has no precise equivalent[25] in either the DSM-IV-TR, where it is most strongly correlated with the diagnosis of antisocial personality disorder, or the ICD-10, which has a partly similar condition called dissocial personality disorder. Both organizations view the terms as synonymous. But only a minority of what Hare and his followers would diagnose as psychopaths who are in institutions are violent offenders.[27][28]
The manipulative skills of some of the others are valued for providing audacious leadership.[29] It is argued psychopathy is adaptive in a highly competitive environment, because it gets results for both the individual and the corporations[30][31][32] or, often small political sects they represent.[33] However, these individuals will often cause long-term harm, both to their co-workers and the organization as a whole, due to their manipulative, deceitful, abusive, and often fraudulent behaviour.[34]
Hare describes people he calls psychopaths as "intraspecies predators[35][36] who use charm, manipulation, intimidation, sex and violence[37][38][39] to control others and to satisfy their own selfish needs. Lacking in conscience and empathy, they take what they want and do as they please, violating social norms and expectations without guilt or remorse".[26] "What is missing, in other words, are the very qualities that allow a human being to live in social harmony."[40]
Early factor analysis of the PCL-R indicated it consisted of two factors.[5] Factor 1 captures traits dealing with the interpersonal and affective deficits of psychopathy (e.g. shallow affect, superficial charm, manipulativeness, lack of empathy) whereas Factor 2 dealt with symptoms relating to antisocial behaviour (e.g. criminal versatility, impulsiveness, irresponsibility, poor behaviour controls, juvenile delinquency).[5]
The two factors have been found by those following this theory to display different correlates. Factor 1 has been correlated with narcissistic personality disorder,[5] low anxiety,[5] low empathy,[41] low stress reaction[42] and low suicide risk[42] but high scores on scales of achievement[42] and well-being.[42]
In contrast, Factor 2 was found to be related to antisocial personality disorder,[5] social deviance,[5] sensation seeking,[5] low socio-economic status[5] and high risk of suicide.[42] The two factors are nonetheless highly correlated[5] and there are strong indications they do result from a single underlying disorder.[43] However, research has failed to replicate the two-factor model in female samples.[44]
Recent statistical analysis using confirmatory factor analysis by Cooke and Michie[45] indicated a three-factor structure, with those items from factor 2 strictly relating to antisocial behaviour (criminal versatility, juvenile delinquency, revocation of conditional release, early behavioural problems and poor behavioural controls) removed from the final model. The remaining items are divided into three factors: Arrogant and Deceitful Interpersonal Style, Deficient Affective Experience and Impulsive and Irresponsible Behavioural Style.[45]
In the most recent edition of the PCL-R, Hare adds a fourth antisocial behaviour factor, consisting of those Factor 2 items excluded in the previous model.[46] Again, these models are presumed to be hierarchical with a single unified psychopathy disorder underlying the distinct but correlated factors.[47]
The Cooke & Michie hierarchical ‘three’-factor model has severe statistical problems—i.e., it actually contains ten factors and results in impossible parameters (negative variances)—as well as conceptual problems. Hare and colleagues have published detailed critiques of the Cooke & Michie model.[48] New evidence, across a range of samples and diverse measures, now supports a four-factor model of the psychopathy construct,[49]which represents the Interpersonal, Affective, Lifestyle, and overt Antisocial features of the personality disorder.
Psychopathy is most commonly assessed with the PCL-R, [50] which is a clinical rating scale with 20 items. Each of the items in the PCL-R is scored on a three-point (0, 1, 2) scale according to two factors. PCL-R Factor 2 is associated with reactive anger, anxiety, increased risk of suicide, criminality, and impulsive violence.
PCL-R Factor 1, in contrast, is associated with extroversion and positive affect. Factor 1, the so-called core personality traits of psychopathy, may even be beneficial for the psychopath (in terms of nondeviant social functioning). A psychopath will score high on both factors, whereas someone with APD will score high only on Factor 2.[51]
Both case history and a semi-structured interview are used in the analysis.
Psychopathy has quite separate legal and judicial definitions that should not be confused with the medical definition. The American Psychiatric Association is vigorously opposing any non-medical or legal definition of what purports to be a medical condition "without regard for scientific and clinical knowledge".[52] Various states and nations have at various times enacted laws specific to dealing with psychopaths.
In the United States approximately twenty states currently have provisions for the involuntary civil commitment for sex offenders or sexual predators, under Sexually violent predator acts, avoiding the use of the term "psychopath". These statutes and provisions are controversial and are being reviewed by the U.S. Supreme Court as a violation of a person's Fourteenth Amendment rights.[53] (See Foucha v. Louisiana for an example.[54])
Primary psychopathy was defined by those following this theory as the root disorder in patients diagnosed with it, whereas secondary psychopathy was defined as an aspect of another psychiatric disorder or social circumstances.[59] Today, primary psychopaths are considered to have mostly Factor 1 traits from the PCL-R (arrogance, callousness, manipulativeness, lying) whereas secondary psychopaths have a majority of Factor 2 traits (impulsivity, boredom proneness, irresponsibility, lack of long-term goals).[60]
Secondary psychopaths show normal to above-normal physiological responses to (perceived) potential threats. Their crimes tend to be unplanned and impulsive with little thought of the consequences.[61] According to those using this theory, this type have hot tempers and are prone to reactive aggression. They experience normal to above-normal levels of anxiety but are nevertheless highly stimulus-seeking and have trouble tolerating boredom. Their lifestyle may lead to depression and even suicide.
Mealey uses the term "primary psychopathy" to differentiate between psychopathy that is biological in origin and "secondary psychopathy" that results from a combination of genetic and environmental influences.[62] Lykken prefers sociopathy to describe the latter.
Sellbom and Ben-Porath (2005) describe the distinction:
Some people who engage in violent behavior possess psychopathic personality traits, such as callousness, grandiosity, and fearlessness, and presumably engage in such conduct because they care little about others. Others are impulsive and experience considerable anger, anxiety, and distress and may commit violent acts as a reaction to negative emotions, which are sometimes referred to as "crimes of passion." Indeed, the distinction between primary and secondary psychopathy (including so-called neurotic psychopathy) has long been noted in the psychopathy literature (Karpman, 1947; Lykken, 1995).[63]
This distinction closely resembles the distinction between instrumental and impulsive/reactive crime/violence in the field of criminology.
Joseph P. Newman et al., who use this concept of psychopathy, have validated David T. Lykken's conceptualization of psychopathy subtypes in relation to Gray's behavioral activation system and behavioral inhibition system.[64] Newman et al. found measures of primary psychopathy to be negatively correlated with Gray's behavioral inhibition system, a construct intended to measure behavioral inhibition from cues of punishment or nonreward.[64] In contrast, measures of secondary psychopathy to be positively correlated with Gray's behavioral activation system, a construct intended to measure sensitivity to cues of behavioral approach.[64]
The difference between sociopathy and psychopathy, according to Hare, may "reflect the user's views on the origins and determinates of the disorder."[65]
David T. Lykken proposes psychopathy and sociopathy are two distinct kinds of antisocial personality disorder. He believes psychopaths are born with temperamental differences such as impulsivity, cortical underarousal, and fearlessness that lead them to risk-seeking behavior and an inability to internalize social norms. On the other hand, he claims sociopaths have relatively normal temperaments; their personality disorder being more an effect of negative sociological factors like parental neglect, delinquent peers, poverty, and extremely low or extremely high intelligence. Both personality disorders are the result of an interaction between genetic predispositions and environmental factors, but psychopathy leans towards the hereditary whereas sociopathy tends towards the environmental.[60]
The criteria for Antisocial Personality Disorder were derived from the Research Diagnositic Criteria developed by Spitzer, Endicott and Robbins (1978). There was concern in the development of DSM-IV there was too much emphasis on research data and not enough on the more traditional psychopathic traits such as a lack of empathy, superficial charm, and inflated self appraisal. Field trial data indicated some of these traits of psychopathy derived from the Psychopathy Checklist developed by Hare et al., 1992, were difficult to assess reliably and thus were not included. Lack of remorse is an example. The antisocial person may express genuine or false guilt or remorse and/or offer excuses and rationalizations. However, a history of criminal acts in itself suggests little remorse or guilt.[66]
The American Psychiatric Association removed the word "psychopathy" or "psychopathic", and started using the term "Antisocial Personality" to cover the disorder in DSM-II.[67]
The World Health Organization's stance in its ICD-10 refers to psychopathy, sociopathy, antisocial personality, asocial personality, and amoral personality as synonyms for dissocial personality disorder. Further, the DSM was meant as a diagnostic guide, and the term psychopath best fit the criteria met for antisocial personality disorder.
No clinical definition of psychopathy indicates that psychopaths are especially prone to commit sexually-oriented murders, and scientific studies do not suggest that a large proportion of psychopaths have committed these crimes.[68] Although some claim a large proportion of such offenders have been classified as psychopathic, this evidence comes from a single, unrepeated research study using the Rorschach Inkblot Test, an invalid test for psychopathy and for sex offenders,[69] references not considering psychopathy, [70] and studies concerning sexual homicide, a somewhat different population than the general class of sex offenders and not from meta-studies combining repeatable results.
The prototypical psychopath has deficits or deviances in several areas: interpersonal relationships, emotion, and self-control. Psychopaths lack a sense of guilt or remorse for any harm they may have caused others, instead rationalizing the behavior, blaming someone else, or denying it outright.[71] Psychopaths also lack empathy towards others in general, resulting in tactlessness, insensitivity, and contemptuousness. All of this belies their tendency to make a good, likable first impression. Psychopaths have a superficial charm about them, enabled by a willingness to say anything without concern for accuracy or truth.
This extends into their pathological lying and willingness to con and manipulate others for personal gain or amusement. The prototypical psychopath's emotions are described as a shallow affect, meaning their overall way of relating is characterized by mere displays of friendliness and other emotion for personal gain; the displayed emotion need not correlate with felt emotion, in other words.
Shallow affect also describes the psychopath's tendency for genuine emotion to be short lived and egocentric with an overall cold demeanor. Their behavior is impulsive and irresponsible, often failing to keep a job or defaulting on debts.[71]
Most research studies of psychopaths have taken place among prison populations. This remains a limitation on its applicability to a general population. Findings indicate psychopathic convicts have a 2.5 time higher probability of being released from jail than undiagnosed ones even though they are more likely to recidivate.[72]
It has been shown that punishment and behavior modification techniques do not improve the behavior of what Hare, and other followers of this theory call a psychopath. Psychopathic individuals have been regularly observed to become more cunning and better able to hide their behaviour. It has been suggested by them traditional therapeutic approaches actually make psychopaths if not worse, then far more adept at manipulating others and concealing their behavior. They are generally considered to be not only incurable but also untreatable.[73]
Psychopaths also have a markedly distorted sense of the potential consequences of their actions, not only for others, but also for themselves. They do not, for example, deeply recognize the risk of being caught, disbelieved or injured as a result of their behaviour.[74]
Psychopaths may often be successful in the military, as they will more readily participate in combat than most soldiers.[75]
Psychopathy is not normally diagnosed in children or adolescents, and some jurisdictions explicitly forbid diagnosing psychopathy and similar personality disorders in minors. Psychopathic tendencies can sometimes be recognized in childhood or early adolescence and, if recognised, are diagnosed as conduct disorder. It must be stressed not all children diagnosed with conduct disorder grow up to be psychopaths, or even disordered at all, but these childhood signs are found in significantly higher proportions in psychopaths than in the general population. Conduct disorder, as well as a related disorder, Oppositional Defiant Disorder, can sometimes develop into adult psychopathy. However, conduct disorder "fails to capture the emotional, cognitive and interpersonality traits - egocentricity, lack of remorse, empathy or guilt - that are so important in the diagnosis of psychopathy."[76]
Children showing strong psychopathic precursors often appear immune to punishment; nothing seems to modify their undesirable behavior. Consequently parents usually give up, and the behavior worsens.[77]
The following childhood indicators are to be seen not as to the type of behavior, but as to its relentless and unvarying occurrence. Not all must be present concurrently, but at least a number of them need to be present over a period of years [78]
The three indicators—bedwetting, cruelty to animals and firestarting, known as the MacDonald triad—were first described by J.M. MacDonald as "red flag" indicators of psychopathy and future episodic aggressive behavior.[79]
The question of whether young children with early indicators of psychopathy respond poorly to intervention compared to conduct disordered children without these traits have only recently been examined in controlled clinical research. The empirical findings from this research have been consistent with broader anecdotal evidence, pointing to poor treatment outcomes.[80]
As part of the larger debate on whether personality disorders are distinct from normal personality or extremes on various dimensions of normal personality is the debate on whether psychopathy represents something "qualitatively different" from normal personality or a "continuous dimension" shading from normality into severely psychopathic. Early taxonometric analysis from Harris and colleagues[81] indicated a discrete category may underlie psychopathy, however this was only found for the behavioural Factor 2 items, indicating this analysis may be related to Anti-social Personality Disorder rather than psychopathy per se. Marcus, John, and Edens more recently performed a series of statistical analysis on previously attained PCL–R and PPI scores and concluded psychopathy may best be conceptualized as having a "dimensional latent structure" like depression.[82]
In contrast, the PCL–R sets a score of 30 out of 40 for North American male inmates as its cut-off point for a diagnosis of psychopathy. However, this is an arbitrary cut-off and should not be taken to reflect any sort of underlying structure for the disorder.
In a 2002 study, David Kosson and Yana Suchy, et al. asked psychopathic inmates to name the emotion expressed on each of 30 faces; compared to controls, psychopaths had a significantly lower rate of accuracy in recognizing disgusted facial affect but a higher rate of accuracy in recognizing anger. Additionally, when "conditions designed to minimize the involvement of left-hemispheric mechanisms" (i.e. sadness) were used, psychopaths had more difficulty accurately identifying emotions. This study did not replicate Blaire, et al. (1997)'s findings that psychopaths are specifically less sensitive to nonverbal cues of fear or distress.[83]
In a 2002 experiment, Blair, Mitchell, et al. used the Vocal Affect Recognition Test to measure psychopaths' recognition of the emotional intonation given to connotatively neutral words. Psychopaths tended to make more recognition errors than controls with a particularly high rate of error for sad and fearful vocal affect.[84]
A 2004 experiment tested the hypothesis of overselective attention in psychopaths using two forms of the Stroop color-word and picture-word tasks: with color/picture and word separated and with color/picture and word together. They found in the separated Stroop tasks, psychopaths performed significantly worse than controls; however, on standard Stroop tasks, psychopaths performed equally well as controls.
When split into low-anxious and high-anxious groups, low-anxious psychopaths and low-anxious controls showed less interference on the separated Stroop tasks than their high-anxious counterparts; for low-anxious psychopaths, interference was very nearly zero. They conclude the inability to integrate contextual cues depends on the cues' relationship to "the deliberately attended, goal-relevant information."[85]
Recent studies have triggered theories on determining whether there is a biological relationship between the brain and psychopathy. One theory suggests that psychopathy is associated with both the amygdala, which is associated with emotional reactions and emotion learning, and the prefrontal cortex, associated with impulse control, decision-making, emotional learning and behavior adaption .[86] Some studies have shown a decrease in "gray matter" in these areas in psychopaths than non-psychopaths. [86] There is new DT-MRI evidence of breakdowns in the white matter connections between these two important areas in a small British study of 9 criminal psychopaths. This evidence suggests that the degree of abnormality was significantly related to the degree of psychopathy and may explain the offending behaviors.[87]
Psychopaths may also have the following other conditions[88] although, in contrast to ASPD, comorbidity among psychopaths is generally found to be low[89][90].
It has been suggested that psychopathy may be comorbid with several other diagnoses than these[91], however limited work on comorbidity has been carried out. This may be because of difficulties in using inpatient groups from certain institutions to assess comorbidity, owing to the likelihood of some bias in sample selection[88]. Furthermore, comorbidity may be more reflective of poor discriminant validity of categories in the DSM-IV than reflective of underlying aetiologically separate conditions[89].
It has been shown that psychopathy is strongly genetic by means of a twin study. Children with anti-social behavior could be classified into two groups: those who were callous acquired their behavior by genetic influences and those who were not callous acquired it from their environment.[92]
