Facet
What is Sincerity? The Honesty-Humility facet, explained
Sincerity is being genuine with people rather than flattering them or putting on a performance to get what you want. It is one of the four facets of Honesty-Humility, the sixth broad factor in the HEXACO model of personality (Lee & Ashton, 2004). A low score describes someone skilled at pleasing people, not someone who lies.

What does sincerity mean?
How genuine you are with people, instead of buttering them up or pretending to get what you want. What you show is what you are: no flattery for advantage, no mask worn to win favour.
In ordinary English, sincerity is the absence of pretence: a sincere apology is one the person means. As a personality facet the word is narrower. It asks one question: do you use a performed version of yourself as a tool to get what you want? The statements on the scale are about flattery, impression management and telling people what they want to hear. That is the whole construct, and it is not a measure of how deeply you feel things or how blunt you are in an argument.
A person low on sincerity might praise an idea they think is weak because the person who proposed it controls the budget. A person high on sincerity asks directly, and is the same person in every room.
Which personality dimension is sincerity part of?
It sits beneath Honesty-Humility, the sixth broad factor in the HEXACO model, alongside fairness, greed avoidance and modesty. The four were grouped together because the words describing them clustered when the trait vocabularies of seven languages were analysed, producing six factors rather than five (Ashton et al., 2004). The full picture is on the HEXACO model page.
Wellington measures it with the HEXACO facet scale for sincerity (HEXACO-PI-R Honesty-Humility: Sincerity facet). Because that is a HEXACO scale, a Big Five test gives you no sincerity score, only a near neighbour: the NEO inventories call it Straightforwardness under Agreeableness, and the public-domain item pool behind most free reports calls the same content Morality (Costa & McCrae, 1992; Goldberg et al., 2006). HEXACO moves it out of Agreeableness, which it leaves as patience and forgiveness under provocation (Ashton et al., 2014). The two are close cousins read differently: Morality is one facet of how you handle people, while sincerity is one quarter of a dimension about whether you take advantage.
How is sincerity different from the other Honesty-Humility facets?
The four look interchangeable in a summary and come apart in a person. Someone can be straight in conversation and still love an expensive watch. Each facet answers its own question.
| Facet | The question it answers | What it looks like in practice |
|---|---|---|
| Sincerity | Do I charm people or go straight at them? | You ask for the pay rise plainly, without the compliments. |
| Fairness | Would I take an advantage that is not mine? | You hand back an overpayment nobody noticed. |
| Greed Avoidance | How much pull do money and status have? | You take the worse-paid job with the better work. |
| Modesty | Do I think I am owed special treatment? | You wait your turn after a very good year. |
The nearest neighbour is fairness, and the line is who bears the cost. Sincerity is the route you take to a person: whether you go straight at them or steer them. Fairness is the thing itself: whether you take what is not yours when nobody would know. You can be scrupulous about money and still flatter your way through a meeting, and modesty asks a third question again, whether you think you are owed more than the people around you.
What does high sincerity look like?
High scorers are the same person with the chief executive and with the person on the front desk. They say what they want rather than engineering the conditions in which someone offers it, decline to praise work they think is poor, and mention the drawback in their own proposal. Over years that builds a reputation: people believe them, including when the news is bad.
- Where it helps. Advisory and teaching roles, long partnerships, and any work where being believed is the main asset.
- What it costs. Networking and self-presentation are real skills, and high scorers often decline to use them. They can seem stiff where charm is the currency, and lose out to someone who asked more artfully.
What does low sincerity look like?
Low scorers are socially fluent in a way that gets results. They notice what a person wants to hear and say it, adjust their manner to the room, and are comfortable presenting a version of themselves that fits the occasion. Much of this is ordinary competence, rewarded in hosting, sales, diplomacy and fundraising.
- Where it helps. Persuasion, negotiation, and any setting where saying exactly what you think would do more harm than good.
- What it costs. The technique gets noticed eventually and is expensive to recover from. Relationships that depend on being believed wear thin, and the habit is hard to switch off in the ones that matter most.
A low score is not an accusation. It is a self-report about style, describing a tendency rather than a verdict. People who score low can be entirely fair in what they do, and people who score high can cause real damage with tactlessness.
What does the research say?
The HEXACO Personality Inventory measures each of its six factors through four narrow scales, sincerity among them. In a validation sample of over 400 people the scales were internally consistent, fitted the hypothesised six-factor structure and showed adequate convergent validity with external variables (Lee & Ashton, 2004). The four facets are grouped because each describes a willingness not to exploit other people when exploiting them would pay, which its authors argue the five-factor model does not capture as a dimension of its own (Ashton & Lee, 2007).
- What the parent dimension covers. A review of the research and theory on Honesty-Humility sets out its lexical origins, how it is measured in the HEXACO-PI-R, and why it is theoretically distinct from HEXACO Agreeableness. It also reports that Five-Factor Model instruments capture only part of the variance in Honesty-Humility, which is the case for measuring it separately (Ashton et al., 2014).
- Why it needed its own factor. A similar six-factor solution emerged from psycholexical studies in seven languages, with Honesty-Humility as a separate factor (Ashton et al., 2004), and five-factor instruments capture only part of that content, folding what remains into Agreeableness (Ashton et al., 2014). Facets are reported alongside the domain because they add bandwidth and predictive power beyond it (Soto & John, 2017).
One honest limit: no study follows the sincerity facet alone across decades, so anyone who tells you what sincerity predicts by itself is extrapolating from the dimension above it.
How does Wellington measure sincerity?
Wellington is a science-based personality assessment from Therabot Labs LLC. It measures personality as continuous traits, built on the Big Five and HEXACO models, and writes the results back as a personal report rather than a type.
The free Snapshot asks 60 questions, takes about 7 minutes and scores six dimensions, the Big Five and Honesty-Humility, so it gives you the sixth factor as a whole rather than this facet alone. The first ten questions are answered before anything is asked of you; after question ten you sign in with an email address so answers are saved and results can be shown. There is no card.
Sincerity arrives with the Wellington Membership, $4.99 a month, which adds the Portrait, 336 questions in 4 chapters and about 36 minutes, to reach 90 traits including all four Honesty-Humility facets and every Big Five facet. 5 statements measure it, each rated on a five-point accuracy scale. They are averaged and placed against a reference sample as a percentile, then reported in one of three bands: Quiet below the 30th percentile, Balanced to the 70th, High above it. Those norms are provisional until the norming sample is complete, so read a result as a direction rather than an exact position. The bands and the Portrait names exist to make the result easier to talk about; the percentile is the measurement, and it is always shown alongside.
Each band has its own written page, prepared in advance by the writing and psychology team, and your answers choose which one you read. The three are The Skilled Host for the Quiet band (You know how to make a room feel good.), The Honest Diplomat for the Balanced band (Genuine by default, gracious when it counts.), and The Clear Glass for the High band (People know exactly where they stand with you.). None is the good one, and the Quiet page describes a social skill with its own costs.
The Wellington Membership, $4.99 a month, reaches 90 traits including every Big Five facet and all 24 character strengths, then adds a short weekly module across 104 weeks toward all 255 traits. See the methodology. Wellington is a wellness tool for reflection, not a medical or psychological diagnosis, and it does not replace care from a qualified professional. It is not built for hiring or selection, and you can export or delete your data at any time.
Questions people ask
- Does a low sincerity score mean I am dishonest?
- No. The scale asks whether you use flattery and impression management to get what you want, not whether you tell the truth. Someone can be completely truthful about facts and still manage every conversation carefully. The question about taking what is not yours is the separate fairness facet.
- What is the difference between sincerity and the Morality facet?
- They cover overlapping ground under different models. Morality, also called Straightforwardness, is a facet of Big Five Agreeableness (Costa & McCrae, 1992). HEXACO moves that content into a sixth factor, leaving Agreeableness as patience and forgiveness (Ashton et al., 2014). Read the two together rather than as duplicates.
- Can sincerity change?
- Somewhat, and slowly. A meta-analysis of 207 intervention studies found trait measures moved by about a third of a standard deviation over an average of 24 weeks, with Emotional Stability moving most, and the changes held at follow-up (Roberts et al., 2017). People who set a goal to change a trait showed measured change over 16 weeks, helped by planning specific actions (Hudson & Fraley, 2015). Both studied Big Five traits, so applying them here is reasonable rather than proven.
- Is being sincere the same as saying everything you think?
- No, and the confusion causes real harm. Sincerity is about not wearing a mask for advantage. It says nothing about timing, tact or how much of your inner life you share. You can keep a confidence and soften bad news without pretending to be someone you are not.
