Low honesty-humility: the core of the dark triad

At the Monday meeting a sentence lands: "I was still finishing it on Sunday, so hopefully it's worth something." Adam is the one presenting. The model the whole analysis rests on was built by Claire, who sent it to him on Thursday evening. She is sitting two chairs away, saying nothing, trying to work out at which second her work turned into his Sunday.

Nobody lied. Adam simply left out one single sentence that most people in his position would have said. Over a year he collects a few dozen such unspoken sentences and builds a career out of them, one to which not a single documented offence can be attached.

From the outside it looks like a trifle. Personality psychology has a surprisingly precise address for this kind of behaviour, and it leads to one trait rather than three separate diagnoses.

Three traits that were given one name

The term dark triad was introduced in 2002 by Delroy Paulhus and Kevin Williams in the Journal of Research in Personality. Until then the three traits had been studied separately, each in its own body of literature. Paulhus and Williams measured them in a single sample of ordinary undergraduates and showed that they hang together without collapsing into one thing.

• Machiavellianism: cold strategy, patience, and the ability to see a social situation as a game with rules that can be worked around.
• Anyone scoring high on narcissism needs admiration and feels entitled to treatment that other people do not get.
• Behind subclinical psychopathy sits emotional distance, low anxiety, and an appetite for acting immediately, with no regard for what follows.

The word psychopathy carries a different meaning here from the one films give it. We are talking about a position on a scale that every person occupies, not a clinical diagnosis and certainly not criminal behaviour. The same holds for the other two traits. There is no zero, and most of the population stays somewhere near the middle.

The shared core goes by the name honesty-humility

Paulhus and Williams looked for what links the three traits, and in the five-factor Big Five model that ruled at the time they found low agreeableness. It fitted only halfway. Agreeableness covers plenty of things that have nothing to do with manipulation, and the essential part slips right through it.

Take narcissism. In a Big Five profile a narcissistic person comes out as a pronounced extravert with healthy self-confidence and mildly reduced agreeableness, a combination any recruiter would happily invite back for a second interview. The dark part literally dissolves in the five factors. That is an uncomfortable finding for anyone who wanted to use a personality questionnaire as a filter.

The Canadian psychologists Kibeom Lee and Michael Ashton took a different route. They examined the words people in various languages had created to describe character, and analyses of adjectives in Korean, Hungarian, Italian, Polish and other languages kept yielding six factors instead of five. The sixth one, the one missing from the Big Five, they named honesty-humility, factor H for short. It covers sincerity, fairness, modesty, and a lack of interest in status won at someone else's expense.

In 2005 Lee and Ashton then measured the dark triad alongside both models at once. Machiavellianism, narcissism and subclinical psychopathy all pointed in the same direction: down the H scale. Factor H also explained their mutual overlap better than agreeableness from the five-factor model.

Three traits that had been studied for twenty years as three different things turned out to be, to a large extent, expressions of one dimension of personality. Both authors summed up their case in the 2012 book The H Factor of Personality, and since then the literature has routinely spoken of a dark core; the team around Morten Moshagen described it in 2018 as a single general factor standing behind the whole family of aversive traits.

What exactly hides under honesty-humility, and why it cannot be mistaken for good manners, is taken apart in a separate piece on how factor H works.

What low H looks like at work

The behaviour that grows out of low H is inconspicuous in an office. There are no outbursts and no loud conflicts, more a thin layer of small shifts that add up.

Credit slowly migrates. "We put this together" for someone else's work and "I put this together" for your own is neither an accident nor carelessness, it is a system. The same family includes the forwarded email with no mention of the original author, or the deck that loses one name from its sources on the way up.

Flattery points almost exclusively upwards. Someone with low H usually knows exactly whose opinion decides promotions and concentrates their attention there; a colleague at the same level gets a different version of the same person. That difference tends to be the first thing a team notices, even if it takes them a long time to name it.

Rules apply asymmetrically. Timesheets, the approval loop, the agreement about who covers on-call over the holidays: all of them can be worked around by someone who treats them as administrative obstacles rather than a shared commitment. And they need not feel like a fraud while doing it. In their inner world they are just solving a problem efficiently.

Now the unpleasant part. Low H has almost nothing to do with intelligence or with conscientiousness, which in HEXACO are entirely different dimensions. A person with low H and high conscientiousness is reliable, delivers on time, never forgets a deadline, and precisely for that reason nobody looks at them closely for a year. The hardest profile to spot is not the chaotic one but the hard-working one.

In relationships: the spell, and then the ledger

Emma describes the first three months with James as the best period of her life. Attention of a kind she had never met before, a trip planned down to the last detail, questions about her childhood. Somewhere in the fifth month it turns, almost imperceptibly. When she refuses to spend a weekend at his parents' place, she hears: "I rearranged an entire working week for you back in January."

This is the part people with low H rarely hide, because it does not strike them as odd. A relationship comes with bookkeeping. A kindness is an investment whose return is tracked, and a sentence beginning "after everything I..." is really an invoice. What is interesting is that in the first weeks such investment tends to be generous. That is exactly why the beginning is so convincing.

When did you last leave a conversation with the feeling that you had just promised something, unable to pin down the sentence in which it happened? It may mean nothing at all. But when that feeling keeps coming back with one particular person over months, it is worth watching which of the two of you it repeatedly works out for.

Lee and Ashton point out something that runs against intuition: people with low H often admit their attitudes in questionnaires quite openly. They do not consider them shameful. Agreeing with a statement like "if I knew I could get away with it, I would take advantage" is not a confession for them but a realistic view of the world. A manipulator who fills in a questionnaire honestly sounds like a contradiction, and yet it is an everyday case.

Why low H does not mean a bad person

Sorting people into the kind and the wicked is comfortable and completely useless for understanding this part of personality. Factor H is a continuous scale, and the vast majority of the population sits in the middle of it. A mildly below-average score makes nobody a predator, only someone who keeps a card up their sleeve while negotiating and does not go weak at the knees over a complaint.

There are situations where lower H pays off. A buyer who never haggles costs the company a fortune over a year. A lawyer who feels obliged to tell the other side everything he knows harms his own client. A salary negotiator whose first offer is also his last walks away with less money than an equally good colleague who has no trouble staying quiet for a few days.

High H, on the other hand, has its own price, and it is paid by the people who have a lot of it. They are easier to needle, they ask less often for what is theirs, and they tend to be the first target of anyone looking for whoever on the team will not make a fuss. A quality we admire in others can be a disadvantage in a concrete situation.

Degree and context are what decide. Cold calculation while negotiating the price of a house is a craft; the same calculation aimed at your own child is something else entirely. The trait by itself does not determine where a person switches it on.

When there is no avoiding such a person

Sometimes it is a manager, sometimes a co-owner of the business or a father-in-law. Leaving is off the table, and what remains is work on what you actually control. A few things tend to help:

• A written trail. After a verbal agreement, send a summary by email, one sentence is enough. It is not a trap, it removes the space in which something else can later be claimed.
• Do not compete in charm or in manipulation. In that discipline you have a negligible chance against decades of practice, and you lose the one advantage you do have: a reputation as someone whose word holds.
• Who owes what to whom? Say it out loud and say it straight away: "Yes, you helped me in January, and I took two of your shifts in February." An account settled in real time cannot be used as leverage later.
• Behaviour over time decides, not the explanation of it. The explanation will always be elegant and will always fit, whereas a pattern of behaviour over six months cannot be explained away.
• Public accusation without evidence turns against whoever makes it. If you decide to escalate, go in with specific data and documents, not with an impression.
• Give up the idea that you will change this person through understanding. Personality traits shift slowly in adulthood, and mainly when the person carrying them has a reason of their own.

Most of those recommendations share one premise: stop asking whether the other person means well. That question has no answer you could ever verify. The question of how the last three situations turned out, the ones where your interests stood against theirs, does have one.

What a questionnaire can do and where it stops

Factor H is measured by self-report, and that has its limits. The result describes your own view of yourself at this moment, not a verdict on your character, and definitely not on anyone else's. No outsider can fill the questionnaire in for you, and estimating a colleague's score from two unpleasant meetings is only ever an estimate.

It is also worth saying that this is not a clinical instrument. It does not diagnose a personality disorder, it does not belong in a consulting room, nor as the sole criterion in a hiring process, and the comparison with other people is approximate. Traits describe tendencies, not destiny, and a person with low H can act fairly for a whole lifetime because that is what they decided to do.

In our HEXACO test you will see honesty-humility next to five other dimensions, which is the only way to read it correctly: low H alongside high conscientiousness looks different in real life from low H alongside high extraversion. If you would rather see the three dark triad traits separately, reach for the Dark Triad test.

Whether you measure the result or not, try one observation for a single month. With every larger piece of work, notice whose name ended up attached to it, and compare that with who spent the most hours on it. In a healthy team those two names usually overlap. When they diverge for the fourth week in a row, and every time in the same direction, you do not have an impression, you have a record.
