# Psychopathy
**Psychopathy** is a personality construct — not a DSM diagnosis — defined by a cluster of traits: superficial charm, grandiosity, pathological lying, manipulativeness, lack of remorse and empathy, shallow affect, impulsivity, and a parasitic, irresponsible lifestyle. It was described clinically by [[Hervey Cleckley]] in *The Mask of Sanity* (1941), whose title is the thesis: the psychopath presents an intact, often charming surface over an absent inner life. [[Robert Hare]] operationalized it in the **Psychopathy Checklist–Revised** (PCL-R, 1991; revised 2003): twenty items scored 0–2 by a trained rater from interview and file, with a cutoff of 30 for "psychopathy" in North American forensic use, and two factors — *interpersonal/affective* (the charm, the lying, the callousness) and *lifestyle/antisocial* (the impulsivity, the criminal versatility). About 1% of the general population scores at that level; in North American prisons the mean score is around 22 and roughly a fifth of inmates cross 30.
## Psychopathy versus ASPD
The DSM's Antisocial Personality Disorder is a *behavioral* diagnosis — a record of rule-breaking since adolescence — and most prisoners qualify. Psychopathy is narrower and *affective*: it requires the emotional deficit, not just the conduct, and most people with ASPD are not psychopaths. The distinction matters for this vault because the interesting cases are the ones the behavioral criteria miss — people whose antisocial traits express through "covert avenues" such as manipulation and white-collar crime rather than through arrest records.
## Successful psychopathy
That is the "successful" or "corporate" psychopathy literature. Babiak and Hare's *Snakes in Suits* (2006) argued that the interpersonal factor — charm, confidence, fearlessness, the ability to read and use people — is selected *for* in organizations that reward those things, and a 2010 study of corporate professionals found PCL-R-defined psychopathy at several times the general-population rate among executives. The finding is contested and the samples small; the vault treats it as a hypothesis with a mechanism, not a settled fact. As one leg of the [[Dark Triad]] (Paulhus and Williams, 2002 — with narcissism and [[Machiavellianism]]), psychopathy is the component that supplies the callousness the other two lack.
## Why the vault cares
Psychopathy is the vault's word for the *absence of the internal brake*. [[Narcissistic Personality Disorder]] describes a person who needs the audience; psychopathy describes one who does not need anyone. The [[Authoritarian Leaders]] and [[Coercive Control]] pages use the construct to distinguish leaders who are wounded from leaders who are simply unconstrained; [[Double Highs]] and [[Social Dominance Theory]] describe the followers and the ideology that reward the trait; Histrionic Personality Disorder and Borderline Personality Disorder are the Cluster B neighbors it is confused with. The [[Goldwater Rule]] caveat on the NPD page applies here with more force: the PCL-R is a forensic instrument requiring interview and records, and no public figure has been scored on it. What can be said from the record is *conduct consistent with the traits*, which is what the vault says.
