HEXACO Personality Test: The Big Five's Smarter Sibling

The Big Five has dominated personality psychology for decades. Five factors — openness, conscientiousness, extraversion, agreeableness, neuroticism — replicated across cultures, languages, and methodologies. Case closed, right?

Not quite. In the early 2000s, researchers Kibeom Lee and Michael Ashton found something the Big Five missed. When they ran factor analyses across multiple languages — not just English — a sixth factor kept emerging: Honesty-Humility. The HEXACO model was born.

What HEXACO Stands For

Six factors, six letters:

  • H — Honesty-Humility
  • E — Emotionality
  • X — eXtraversion
  • A — Agreeableness
  • C — Conscientiousness
  • O — Openness to Experience

Four of these overlap substantially with Big Five traits. Two diverge in important ways. And that sixth factor — the H — changes the entire picture of human personality.

The Sixth Factor: Honesty-Humility

This is what makes HEXACO worth knowing about.

Honesty-Humility measures your tendency toward sincerity, fairness, greed avoidance, and modesty. High scorers are straightforward, uninterested in manipulating others, and don't feel entitled to special treatment. Low scorers are more willing to bend rules for personal gain, flatter strategically, and feel they deserve more than others.

Why did the Big Five miss this? Partly because early Big Five research relied heavily on English-language lexical studies. The Honesty-Humility factor showed up more clearly in analyses of other languages — Korean, French, Italian, Dutch, German, Filipino, and others. Cross-linguistic analysis revealed that sincerity and humility cluster together as a distinct factor separate from agreeableness.

This matters practically. Honesty-Humility is the single strongest personality predictor of workplace counterproductive behavior — theft, fraud, rule-breaking, bullying. It predicts unethical decision-making better than any Big Five trait. It's the factor that separates the colleague who returns excess change from the one who pockets it.

How HEXACO Differs From the Big Five

The differences are more than just adding a sixth factor. HEXACO reorganizes personality space:

Emotionality vs. Neuroticism

Big Five neuroticism captures anxiety, depression, anger, and vulnerability all in one trait. HEXACO splits these up. Emotionality covers anxiety, fearfulness, dependence, and sentimentality. The anger component moves to low agreeableness instead.

This split makes psychological sense. Being anxious and being irritable aren't the same thing, and grouping them together muddies the picture. Someone can be emotionally sensitive (high emotionality) without being hostile, or easily angered (low agreeableness) without being anxious.

Agreeableness Reshuffled

Big Five agreeableness mixes warmth, trust, compliance, and lack of hostility. HEXACO agreeableness is narrower: patience, tolerance, flexibility, and forgiveness — essentially your capacity to get along with people who annoy you. The warmth and sentimentality components move to emotionality.

The result is a cleaner separation. HEXACO agreeableness is specifically about interpersonal friction management. How much provocation can you absorb before you snap?

The Other Four

Extraversion, conscientiousness, and openness work largely the same as in the Big Five. Slight differences in which facets load where, but the core meaning is preserved.

Taking the HEXACO Test

The official HEXACO personality inventory comes in several versions:

HEXACO-PI-R (200 items) — The full version. Measures all six factors with four facets each, totaling 24 facets. Takes about 25-30 minutes. Best for research or serious self-assessment.

HEXACO-60 — A 60-item version that's quick and still reasonably reliable. Good enough for most people who want to understand their profile without a half-hour commitment.

HEXACO-100 — The sweet spot between brevity and comprehensiveness. Often used in research when the full 200 items aren't practical.

All versions are freely available from Lee and Ashton's research site. No sign-up required, no paid "premium report" upsell. This is an academic instrument made available for public use — refreshingly different from most personality tests online.

What Your HEXACO Profile Reveals

Each factor tells you something specific:

High Honesty-Humility — You play fair without needing surveillance. You don't exaggerate accomplishments, don't manipulate for advantage, and feel genuinely uncomfortable with deception. Others might see you as "too nice" or naive, but you're not — you just don't see the point in playing games.

Low Honesty-Humility — You're pragmatic about ethics. Rules are guidelines, social norms are tools, and getting ahead sometimes means bending things. This isn't inherently pathological — plenty of successful people operate here — but it does predict higher risk for dark personality traits.

High Emotionality — Stress hits you harder. You experience fear and anxiety more intensely, form stronger emotional attachments, and empathize deeply with others' suffering. You probably have a smaller but tighter social circle.

Low Emotionality — Tough-minded. You don't scare easily, recover from setbacks quickly, and can handle disturbing situations without falling apart. Useful in emergency medicine or combat. Less useful if your partner needs emotional validation.

High Extraversion — Social energy is your default. You seek out people, enjoy being the center of attention, and feel restless when alone too long.

Low Extraversion — Solitude recharges you. Social situations drain energy rather than generate it. See introvert personality type for more on this.

High Agreeableness — Conflict makes your skin crawl. You forgive easily, give people the benefit of the doubt, and accommodate others even at your own expense.

Low Agreeableness — You hold grudges, call people out, and don't pretend disagreements don't exist. Sometimes abrasive, but also the person who says what everyone is thinking.

High Conscientiousness — Organized, disciplined, thorough. You finish what you start and your workspace isn't a disaster zone.

Low Conscientiousness — Flexible, spontaneous, unbothered by mess. You work in bursts of inspiration rather than steady routines. Deadlines are suggestions.

High Openness — Intellectually curious, creative, drawn to novelty. You read widely, think abstractly, and get bored by convention.

Low Openness — Practical, concrete, traditional. You prefer proven methods over experimental ones and don't see the point of art for art's sake.

HEXACO and the Dark Side of Personality

Here's where HEXACO really shines. The dark triad — narcissism, Machiavellianism, and psychopathy — has fascinated researchers for years. Within the Big Five, these traits scatter across multiple factors without clean mapping.

HEXACO solves this. Low Honesty-Humility is the common core of all three dark triad traits. Narcissists feel entitled to special treatment (low modesty, low greed avoidance). Machiavellians manipulate strategically (low sincerity, low fairness). Psychopaths exploit without remorse (low across the board).

This doesn't mean low H automatically makes you a psychopath. It means the tendency toward self-serving behavior — the willingness to exploit situations for personal gain — exists on a continuum, and HEXACO measures it directly while the Big Five doesn't.

Research by Lee and Ashton showed that Honesty-Humility accounts for variance in dark personality traits that the Big Five simply can't capture. If you want to understand the full range of human personality — including the uncomfortable parts — HEXACO gives you a more complete picture.

Is HEXACO Better Than the Big Five?

Depends what "better" means.

For prediction: HEXACO predicts workplace behavior (especially counterproductive behavior) better than the Big Five. It also predicts political attitudes, religious beliefs, and moral reasoning more precisely.

For comprehensiveness: Six factors capture more personality variance than five. The added Honesty-Humility dimension fills a genuine gap.

For adoption: The Big Five still dominates. Most existing research, most organizational assessments, most clinical tools use Big Five frameworks. HEXACO is gaining ground but isn't the standard yet.

For practical self-insight: Both work well. If you've already taken a Big Five test and found it helpful, HEXACO adds the Honesty-Humility dimension and reorganizes emotionality and agreeableness for cleaner interpretation.

The honest take: HEXACO is a genuine improvement over the Big Five, backed by solid cross-cultural research. It hasn't replaced the Big Five because scientific paradigms shift slowly, not because the evidence is weak.

HEXACO vs. Other Personality Frameworks

How does HEXACO compare to popular personality test alternatives?

Compared to MBTI, HEXACO is in a completely different league psychometrically. MBTI measures preferences with dichotomous categories. HEXACO measures traits on continuous dimensions with demonstrated reliability and validity. There's no serious debate here — HEXACO is more scientifically sound.

Compared to the Enneagram, HEXACO is empirically derived rather than tradition-based. The Enneagram offers richer narrative and motivational depth. HEXACO offers better measurement precision.

Compared to DISC, HEXACO measures broader and deeper. DISC covers behavioral style in workplace contexts. HEXACO covers the full personality landscape.

Taking a Personality Assessment

HEXACO represents one of the best empirically-grounded personality models available. If you want to understand yourself through rigorous science, it's an excellent starting point.

Want a different approach? Take our free personality assessment — it uses adaptive questioning and Bayesian inference to map your psychological drives across five dimensions, producing a nuanced probability distribution rather than a fixed category. It captures personality through the lens of motivation and archetypes, giving you both precision and narrative depth.
