HEXACO and RIASEC: the models behind Haliscope
For most of the last century, two fields worked in parallel without talking much. One got good at describing people. The other got good at describing work.
Haliscope takes the best-supported model from each — HEXACO and RIASEC — and reports eleven traits drawn from both. Neither one answers the career question alone.
Part one
HEXACO
Six personality factors. Describes the person.
Part two
RIASEC
Six interest types. Describes the work too.
Part three
Eleven Haliscope traits
Built from both, so your scores can be matched to real jobs.
Part one — personality
HEXACO: the sixth factor
In 2004, Michael Ashton and Kibeom Lee repeated the classic personality studies in more languages and found a sixth trait the Big Five had been quietly absorbing into another one.
It turns out to be the trait most closely tied to behaving badly at work — and almost nobody outside the field has heard of it. Five of the six below will look familiar. The first won’t.
- HHonesty-Humility
Sincerity, fairness, modesty, and the absence of entitlement. High scorers are reluctant to manipulate others for gain, uninterested in status for its own sake, and unwilling to break rules when nobody would notice. Low scorers will flatter to get ahead and carry a sense of self-importance.
This is the one the Big Five doesn’t have. Pulling it out from under agreeableness is what gives the model its edge.
- EEmotionality
Anxiety, sentimentality, and how much reassurance you need. Close to what the Big Five calls neuroticism, but framed as sensitivity to threat rather than instability.
Anger sits under agreeableness here instead, which is a tidier place for it.
- XeXtraversion
Boldness, sociability, and liveliness. How much you seek other people out, and how comfortable you are with attention on you.
The trait most people judge accurately about themselves.
- AAgreeableness
Forgiveness, patience, and flexibility. Specifically: how much you tolerate other people’s failings, and whether you let things go.
Narrower than the Big Five version, since honesty now has its own trait.
- CConscientiousness
Organization, diligence, and care. How you plan, how closely you check your work, and how long you think before acting.
The most reliable predictor of job performance across occupations.
- OOpenness to Experience
Curiosity, creativity, and appetite for the unfamiliar.
Much the same as its Big Five counterpart.
Why the sixth factor matters at work
Take two people who both score high on Big Five agreeableness. Both are pleasant, both avoid conflict, both get described as easy to work with. One of them also takes credit that isn’t theirs when nobody’s watching. The Big Five can’t tell them apart. HEXACO can.
That’s why it matters for career fit. Some jobs are built on trust nobody can check in the moment — clinical care, audit, safeguarding, anything fiduciary. Score high here and that work feels like an extension of how you already operate. Score low and it becomes a friction that’s hard to name.
Two of the eleven Haliscope traits come from here: Law-Abiding, for how you treat rules and obligations, and Harmonizing, for how you weigh other people’s interests against your own.
How HEXACO compares to the Big Five
| Dimension | Big Five | HEXACO |
|---|---|---|
| Number of factors | 5 | 6 |
| Integrity | Inside agreeableness | Its own factor (H) |
| Anger | In neuroticism | In agreeableness |
| Cross-language replication | Strong | Strong, across a wider language set |
| Research base | Very large — decades of accumulation | Smaller, growing since 2004 |
Neither model replaces the other. The Big Five has far more research behind it; for career questions we think HEXACO is the better starting point. Sources: Ashton, M. C. & Lee, K.

Part two — interest
RIASEC: describing the work too
In 1959 the psychologist John Holland had a simple idea: describe people and jobs using the same six words. Once both sides are in the same language, fit stops being an opinion and becomes something you can work out.
It’s the reason a career assessment can name actual jobs rather than adjectives.
- RRealistic
Working with tools, machines, materials, plants, animals, and physical systems. Practical, concrete problems with visible results.
Electricians, surveyors, veterinary technicians, aircraft mechanics.
- IInvestigative
Observing, reasoning, and working problems apart. Preference for questions that need evidence rather than persuasion.
Epidemiologists, actuaries, software developers, research scientists.
- AArtistic
Unstructured work where the form isn’t given in advance. Self-expression, originality, and tolerance for ambiguity in the brief.
Architects, editors, industrial designers, landscape architects, art directors.
- SSocial
Teaching, helping, caring for, and developing other people. Satisfaction that comes from someone else’s outcome.
Nurses, teachers, physical therapists, social workers.
- EEnterprising
Leading, persuading, selling, and taking on commercial risk. Comfort with influence as the main instrument of the work.
Sales managers, lawyers, founders, public administrators.
- CConventional
Ordering data, following defined procedure, and working to a standard. Precision valued over improvisation.
Accountants, paralegals, logisticians, medical records specialists.
Why the hexagon matters
The six types aren’t just a list. Holland put them in a hexagon because the distances mean something: neighbors are alike, opposites aren’t. Realistic sits across from Social, Investigative across from Enterprising, Artistic across from Conventional.
That’s more useful than it sounds. Leaning Investigative and Artistic is a coherent profile — they’re neighbors. Scoring high on both Realistic and Social means you’re pulled in two directions, which is worth designing a career around rather than ignoring.
Where the data comes from
O*NET, the U.S. Department of Labor’s jobs database, publishes RIASEC profiles for over 900 occupations alongside their tasks and working conditions. It’s free, it’s kept current, and it’s what turns a trait score into a list of jobs.
The evidence, briefly: the six types hold up well, though the neat hexagon fits some groups better than others. Interest tests have the best track record of any assessment type at predicting what work people choose, stay in, and enjoy. They’re much weaker at predicting how well someone will do it — which is exactly why the personality half is there.

Part three — the synthesis
How the two come together
Each model answers half the question. RIASEC tells you what work you’re drawn to and nothing about how you’ll handle it. HEXACO describes how you operate and knows nothing about jobs. Apart, they give you two reports that don’t talk to each other.
Interest without personality is unstable
Two people equally drawn to caring work will last very different lengths of time in it. Wanting the job isn’t the same as being able to sustain it.
Personality without interest names nothing
Six accurate scores can still leave you exactly where you started. No job is attached to a high openness score — personality models were never built to point at one.
Eleven traits spanning both
Instead of two separate score sets, Haliscope builds eleven traits that draw on both at once — so one score tells you something about what you want and how you work.
The eleven traits are Helping, Harmonizing, Analyzing, Law-Abiding, Influencing, Safety-Seeking, Creating, Operating, Organizing, Persevering, and Exploring. Their nine distinct initials spell the product name: Helping and Harmonizing share the H, Operating and Organizing the O.
They are Haliscope’s own set, built as an evolution of the two models rather than taken from either — and several deliberately draw on both at once. Analyzing comes from RIASEC’s Investigative and HEXACO’s openness; Organizing from Conventional and conscientiousness. Others lean almost entirely one way — Operating is Realistic, Persevering is conscientiousness. The overlap is the point. Forcing the two models apart would give us tidier traits that describe people worse.
Because the RIASEC half uses the same vocabulary O*NET uses for jobs, your scores can be compared directly against occupational data — and against the people already doing the work. Haliscope scores the roughly three hundred occupations for which O*NET publishes every input, out of a database of 900+. The scoring rules and limitations are on the methodology page.
Neither model is ours, and neither is finished. HEXACO is twenty years old and still gathering evidence; RIASEC is older than the internet and shows it in places. We use them because they’re the best-supported descriptions available of the person and of the work — and because you should be able to check the sources.
Questions
Can I take a free HEXACO test?
Yes — the HEXACO-PI-R is free for personal use at hexaco.org. You get the six scores and nothing else: no jobs, no interpretation.
Can I take a free RIASEC test?
Yes — the O*NET Interest Profiler is free and public domain. It gives you six interest scores and matching jobs, but measures no personality, so it can’t say how you’d fare in them.
Why not just use the Big Five and RIASEC?
You could, and it would work fine. HEXACO’s advantage is the sixth trait, which separates integrity from general agreeableness — and that matters for the many jobs built on unsupervised trust. Longer version on the Big Five comparison.
Does Haliscope report HEXACO or RIASEC scores directly?
Not as six-factor or six-type scores. The eleven traits are built across both so results can be matched to jobs. The methodology page shows where each one comes from.
Is either model used in hiring?
Some integrity tests draw on the honesty-humility research. Screening candidates with any personality test raises fairness and legal questions that vary by state, and Haliscope isn’t validated for it.
