Dark Triad Types

Narcissism, Machiavellianism and Psychopathy — origins, HEXACO drivers, examples and what they look like in the wild.

Take the HEXACO test

Overview

The "Dark Triad" groups three related personality tendencies that predict callousness, manipulation and risk-taking: Narcissism (grandiosity and entitlement), Machiavellianism (strategic manipulation and cold strategic planning), and Psychopathy (impulsivity, low fear and reduced empathy). They overlap but have different psychological drivers and real-world expressions.

Below we summarize which HEXACO dimensions tend to enable each trait, illustrative fictional and real-world examples, the types of antisocial or exploitative acts they're more likely to commit, and notable research-backed observations.

How HEXACO maps to the Dark Triad (quick guide)

  • Honesty–Humility (H): Low H is the single strongest HEXACO predictor of exploitative, manipulative, and self-interested behaviour across all three dark traits. People low in H are more willing to lie, cheat, and take unfair advantage.
  • Agreeableness (A): Low A (versus high A) is associated with callousness and vindictiveness. Low A amplifies the interpersonal coldness in Machiavellianism and Psychopathy.
  • Emotionality (E): Low Emotionality (i.e., lower anxiety, fear and attachment) is particularly aligned with psychopathic features — fearlessness, lack of distress, and low empathy-driven concern.
  • Extraversion (X): Higher Extraversion can support narcissistic displays (charisma, attention-seeking) but is not sufficient on its own.
  • Conscientiousness (C): Low C is common in impulsive psychopathy; by contrast, Machiavellianism often pairs low H with relatively intact or even higher C because strategic manipulation requires planning.
  • Openness (O): Openness shows weaker direct links, but can influence the style of antisocial behaviour (novelty-seeking vs. traditional exploitation).

Narcissism

Core features: grandiosity, strong need for admiration, entitlement, and sensitivity to status threats. Narcissism centers on an inflated self-image and a preference for attention and dominance.

HEXACO drivers

  • Low Honesty–Humility: enables exploitative tendencies and entitlement.
  • High Extraversion: social boldness and charisma that support attention-seeking.
  • Average or variable Conscientiousness: some narcissists are disciplined achievers, others are less organized.

Examples (fictional & non-fictional)

Fictional: a charismatic public figure who constantly seeks praise and expects special treatment (e.g., certain literary or screen antagonists who dominate scenes with charm and grandiosity).
Non-fictional: high-profile executives or celebrities who use their status to bend rules, or con artists who craft a larger-than-life persona to attract followers.

Behaviors & risks

Narcissistic individuals are more likely to engage in reputation-driven exploitation: confidence tricks, frauds based on charisma, workplace bullying, abuse of power, and public scapegoating. Narcissism can also fuel aggressive retaliation when status is threatened.

Interesting notes

  • Narcissism has both vulnerable and grandiose forms; vulnerable narcissists can be hypersensitive and anxious despite entitlement.
  • Because many narcissists are socially skilled, their exploitative acts can be subtle and hard to detect until harm accumulates.

Machiavellianism

Core features: strategic manipulation, cynicism about others, long-term planning to achieve self-interested goals, and emotional detachment used instrumentally.

HEXACO drivers

  • Low Honesty–Humility: willingness to deceive or exploit to reach goals.
  • Low Agreeableness: cold interpersonal stance and readiness to use others.
  • Relatively higher Conscientiousness compared with psychopathy: planning, patience and foresight that help strategy.

Examples (fictional & non-fictional)

Fictional: the classic courtly schemer who arranges events and people to their advantage (e.g., Petyr 'Littlefinger' Baelish from popular fiction).
Non-fictional: career manipulators who use social engineering and careful planning — from corporate white-collar fraudsters to political fixers who trade favors and information.

Behaviors & risks

Machiavellianism predicts calculated, often long-running exploitations: embezzlement, corporate fraud, large-scale scams, sophisticated social-engineering, and corruption. Because these acts are planned, they can cause systemic harm before detection.

Interesting notes

  • Machiavellian strategists are often patient and able to mask motives for long periods.
  • They may appear competent and trustworthy on the surface; scrutiny of incentives and oversight systems is essential to catch them.

Psychopathy

Core features: impulsivity, fearless dominance, shallow affect, low empathy, and blunted remorse. Psychopathy is closely associated with antisocial and risk-taking behaviour.

HEXACO drivers

  • Low Emotionality: reduced fear and anxiety, low attachment and low stress reactivity.
  • Low Honesty–Humility and Low Agreeableness: amplify exploitative and callous acts.
  • Low Conscientiousness: in many cases, impulsive tendencies and poor planning.

Examples (fictional & non-fictional)

Fictional: the remorseless antagonist who acts without conscience or fear (e.g., certain thriller or crime protagonists/antagonists).
Non-fictional: offenders whose actions are characterized by violent impulsivity, repeat offending, or callous exploitation of others.

Behaviors & risks

Psychopathy is most strongly linked to impulsive and sometimes violent crime, reckless endangerment, and a higher risk of recidivism. It also appears in non-violent contexts as severe workplace exploitation, high-risk financial crimes, or reckless corporate decisions that harm others.

Interesting notes

  • Not all people with psychopathic traits are criminals — some channel fearlessness and low distress into high-risk, high-reward careers (e.g., emergency services, certain business roles), though this can be adaptive or destructive depending on context.
  • Psychopathy is associated with poorer response to empathy-based interventions; behavioural controls and structural safeguards are often more effective than appeals to conscience.

Practical takeaways

  • Low Honesty–Humility and low Agreeableness are common across all three traits — those traits are the strongest HEXACO red flags for exploitative behaviour.
  • Look at the pattern: impulsive, fearless rule-breaking points toward psychopathy; long-term strategic exploitation points toward Machiavellianism; status-seeking, attention-demanding behaviour signals narcissism.
  • Prevention is structural: transparent incentives, checks on power, and monitoring reduce harm more reliably than individual "rehabilitation" for people with entrenched dark-triad traits.

Further reading & research notes

The Dark Triad is an active area of research in personality psychology. Researchers use combinations of self-report measures, behavioural tasks and longitudinal data to understand how these traits predict real-world outcomes. For applied settings, the focus is on risk mitigation and organizational safeguards rather than pathologizing individuals.
