Personality test statistics, from real results: Across more than 8,500 completed test results on JobCannon, the most common MBTI result is ISTJ (21.9%) and the rarest is ENFJ (1.1%); the most common primary love language is Acts of Service (34.1%); and among Big Five takers, Openness (38.3%) is the most frequent dominant trait. Every figure below is first-party, computed from our own anonymized taker data, with the sample size shown for each test.
Most "personality statistics" you find online trace back to decades-old estimates or vendor marketing. The numbers on this page are different: they are computed directly from real, completed tests taken on JobCannon, aggregated with no personally identifiable information. You can take any of these free tests yourself, and the full open dataset lives at jobcannon.io/research/distributions.
How we compiled these personality test statistics
These figures come from JobCannon's own assessment_results data as of the June 2026 pull. For each test, we counted how often each result type appeared among people who finished it, then expressed each as a percentage of takers. We publish the sample size (n) next to every distribution so the weight of each number is transparent.
One honest caveat up front: everyone in this data chose to take a free personality test online. That makes it a self-selected sample, not a nationally representative survey. These numbers describe JobCannon takers, not the whole population. That is exactly why we show the sample size and never round it into a universal claim.
MBTI type distribution (n = 1,972)
The 16-type distribution is our largest personality dataset. Introverted, sensing types cluster at the top, and the four rarest results are all extraverted.
| Type | Share of takers |
|---|---|
| ISTJ | 21.9% |
| ISFJ | 11.4% |
| INFP | 9.1% |
| INTJ | 7.9% |
| ESTJ | 7.4% |
| ISTP | 7.0% |
| INTP | 6.7% |
| INFJ | 4.9% |
| ISFP | 4.9% |
| ESFJ | 4.2% |
| ENFP | 3.9% |
| ENTP | 3.1% |
| ESTP | 2.8% |
| ESFP | 2.0% |
| ENTJ | 1.9% |
| ENFJ | 1.1% |
- Most common type: ISTJ (21.9%) — more than one in five takers.
- Rarest type: ENFJ (1.1%), narrowly rarer than ENTJ (1.9%) and ESFP (2.0%).
- Introvert-heavy: the four most common results are all introverted, together making up just over half of all takers.

DISC style distribution (n = 969)
DISC primary styles are far more evenly spread than MBTI types. Conscientiousness and Steadiness edge out Dominance, with Influence the least common primary style.
- C (Conscientiousness): 28.1%
- S (Steadiness): 27.0%
- D (Dominance): 25.8%
- I (Influence): 19.1%
Enneagram type distribution (n = 745)
Among Enneagram takers, Type 1 leads, and Types 4 and 5 tie for second — a reflective, principled skew.
- Type 1 (Reformer): 23.0%
- Type 4 (Individualist): 20.0%
- Type 5 (Investigator): 20.0%
- Type 2 (Helper): 15.6%
- Type 3 (Achiever): 8.2%
- Type 6 (Loyalist): 4.8%
- Type 7 (Enthusiast): 3.8%
- Type 8 (Challenger): 2.7%
- Type 9 (Peacemaker): 2.0%
Big Five: which trait dominates (n = 976)
When we look at each person's single highest Big Five trait, Openness is the most common dominant factor and Extraversion the least. Population mean scores tell the same story: takers score highest on Openness and Agreeableness.
- Most common dominant trait: Openness (38.3%), then Agreeableness (25.5%), Conscientiousness (18.2%), Neuroticism (11.9%), Extraversion (6.0%).
- Highest average scores: Openness (71.5 / 100) and Agreeableness (69.3), then Conscientiousness (61.3), Neuroticism (52.2) and Extraversion (48.4).
The Big Five is the most scientifically validated of these frameworks — see our history of the OCEAN model, or take the free Big Five test.
Love languages distribution (n = 454)
Acts of Service is the runaway most common primary love language, while Quality Time is surprisingly rare as a top result.
- Acts of Service: 34.1%
- Words of Affirmation: 25.6%
- Receiving Gifts: 19.4%
- Physical Touch: 15.6%
- Quality Time: 5.3%
Moral alignment (D&D) distribution (n = 554)
Our nine-box alignment quiz produces a striking skew: the three "evil"-leaning and neutral boxes dominate, and Lawful and Chaotic Good are among the rarest.
- Chaotic Evil: 18.4%
- Neutral Evil: 18.4%
- True Neutral: 18.2%
- Neutral Good: 12.8%
- Chaotic Neutral: 9.4%
- Lawful Evil: 7.2%
- Lawful Neutral: 6.3%
- Lawful Good: 5.6%
- Chaotic Good: 3.6%
Read this one with the self-selection caveat firmly in mind — a playful quiz attracts playful, contrarian answers, and "picking evil for fun" is part of the format.
Spirit animal, temperament, EQ and more
The same first-party approach covers our lighter and shorter tests too.
- Spirit animal (n = 1,431): Eagle 20.3%, Owl 16.8%, Dolphin 15.4%, Wolf 13.1%, Lion 12.6%, Fox 10.8%, Deer 6.8%, Bear 4.2%.
- Four temperaments (n = 423): Sanguine 41.1%, Choleric 30.7%, Phlegmatic 17.0%, Melancholic 11.1%.
- Emotional intelligence — strongest domain (n = 296): Self-Awareness 45.9%, Empathy 26.4%, Self-Regulation 15.2%, Social Skills 12.5%.
- Multiple intelligences — top intelligence (n = 518): Interpersonal 21.2%, Intrapersonal 19.1%, Linguistic 12.9%, Logical 12.5%, Musical 11.6%, Bodily 10.4%, Spatial 7.1%, Naturalist 5.0%.
- Dark Triad — highest trait (n = 169): Machiavellianism 50.9%, Narcissism 46.2%, Psychopathy 3.0%.
What these personality statistics actually tell us
Three patterns hold up across our data. First, type frameworks are lopsided: MBTI and Enneagram concentrate most takers into a handful of results, while dimensional tools like DISC and Big Five spread people more evenly. Second, the "rare type" mystique is real but small — the rarest MBTI result (ENFJ) still shows up in more than 1 in 100 takers. Third, and most important, audience shapes the numbers: a free, online, self-selected sample leans reflective and introverted, which is why we never present these as universal human averages.
