Difference between HEXACO and big five?
Quick answer: The main difference between HEXACO and the Big Five is that HEXACO has six factors instead of five, adding Honesty-Humility — sincerity, fairness, and modesty. HEXACO also reframes Big Five neuroticism as "Emotionality" and redistributes some agreeableness content. Both are validated trait models, but HEXACO better predicts integrity and manipulative behavior.
The headline difference: a sixth factor
Both models come from the same scientific tradition — lexical research analyzing how people describe personality across languages. The Big Five settled on five factors (OCEAN). Later cross-cultural studies by Kibeom Lee and Michael Ashton found a reliable sixth factor kept emerging, giving rise to HEXACO.
That sixth factor is Honesty-Humility: sincerity, fairness, modesty, and freedom from greed. The Big Five doesn't isolate it — pieces of it get absorbed into agreeableness. Pulling it out into its own dimension is HEXACO's defining move, and it's why HEXACO predicts ethical behavior and the "dark triad" traits (manipulation, narcissism, exploitation) more sharply.
Beyond the sixth factor: quieter differences
The two models don't just differ by one trait. HEXACO also rearranges some content:
- Emotionality vs. Neuroticism: HEXACO's Emotionality drops the anger/hostility component (which moves toward low Agreeableness) and emphasizes sentimentality and need for support.
- Agreeableness: In HEXACO, Agreeableness absorbs the calm-versus-tempered dimension, so it's about patience and forgiveness more than the Big Five version.
- The other four — Extraversion, Conscientiousness, Openness — line up closely between the models.
| Aspect | Big Five (OCEAN) | HEXACO |
|---|---|---|
| Number of factors | 5 | 6 |
| Honesty-Humility | Not isolated | Its own factor |
| Neuroticism / Emotionality | Includes anger | Anger shifts to low Agreeableness |
| Best at predicting integrity | Moderate | Stronger |
| Overlapping factors | E, C, O, and part of A | Same four align closely |
Which should you use?
Neither is simply "better"; they suit different aims.
- Choose the Big Five if you want the most widely used, heavily researched framework — the standard reference for most psychology and workplace applications.
- Choose HEXACO if you care specifically about honesty, fairness, ethics, or predicting exploitative behavior. Its Honesty-Humility factor gives it an edge there.
Many modern assessments, including the one behind Helel, draw on both so you get the breadth of OCEAN plus the ethical precision of Honesty-Humility.
Neither is a diagnosis
Both models describe normal personality variation, not mental-health conditions. Scores map tendencies and trade-offs, not good-versus-bad character in any clinical sense, and shouldn't guide medical decisions. If you're facing distress, a licensed professional is the right resource; personality tools are for self-understanding.
Get both frameworks in one profile
Helel offers a free, clinically grounded personality test built on the Big Five, HEXACO, and NEO PI-R traditions — roughly 300 data points, including Honesty-Humility. Once you approve your profile, you can explore it in live-video conversation with an AI companion that adapts to your measured personality, turning two rigorous frameworks into one clear picture of how you're wired. It's for growth and self-understanding, and a complement to, not a substitute for, professional care.

Frequently asked questions
Is HEXACO better than the Big Five?
Not universally. HEXACO better predicts honesty, fairness, and manipulative behavior thanks to its Honesty-Humility factor. The Big Five is more widely used and researched. The best choice depends on what you want to understand.
What is the extra factor in HEXACO?
It's Honesty-Humility, capturing sincerity, fairness, modesty, and low greed. The Big Five spreads these qualities across other traits, while HEXACO measures them as a distinct sixth dimension.
Do HEXACO and the Big Five give the same result for me?
Largely overlapping but not identical. Four factors align closely, but HEXACO adds Honesty-Humility and reframes emotionality and agreeableness, so your profile can look slightly different across the two models.
