What HEXACO is
HEXACO is a model of personality structure that describes individual differences along six broad dimensions: Honesty-Humility, Emotionality, Extraversion, Agreeableness, Conscientiousness, and Openness to Experience. It was developed by Kibeom Lee and Michael Ashton from lexical studies, which examine the trait adjectives that natural languages encode, on the assumption that the characteristics people find important tend to become words. The framework resembles the Big Five but adds a sixth factor, Honesty-Humility, covering sincerity, fairness, modesty, and a lack of greed. Two factors are also defined slightly differently: Emotionality takes in empathy and emotional attachment, while tendencies toward anger fall under (low) Agreeableness rather than under emotional instability.
What it isn't
HEXACO is not a clinical or diagnostic instrument; it measures normal-range personality, not disorders or mental health. It is not a typology that sorts people into named categories or boxes, since each dimension is a continuum on which a score simply falls higher or lower. It is not a fixed verdict or destiny, as the traits describe broad tendencies rather than dictate what someone will do in any given moment. And no dimension, or either end of one, is inherently good or bad; every level carries its own characteristic strengths and trade-offs.
Why it's useful
A practical strength of HEXACO is its cross-cultural grounding: the six-factor structure has emerged from lexical research across many different languages, suggesting the dimensions are not specific to any single culture. Its most distinctive contribution is the Honesty-Humility factor, which captures variation that the Big Five tends to miss. Honesty-Humility relates to behaviors such as fairness, exploitation of others, materialism, and rule-following, making the model especially informative for research on integrity, ethics, and cooperation, areas where the five-factor approach offers less coverage.
Where it came from
HEXACO grew out of the lexical hypothesis and a series of lexical studies conducted in multiple languages during the 1990s and 2000s. Analyses of trait terms in languages including Korean, French, German, Italian, Dutch, and others repeatedly recovered six factors rather than five. This prompted Kibeom Lee and Michael Ashton to formalize the model and develop the HEXACO Personality Inventory-Revised (HEXACO-PI-R) to measure it. The official inventory, along with scoring keys and supporting materials, is made freely available at hexaco.org.

Honesty-Humility measures the tendency to be fair, genuine, and modest in dealings with others, even when one could gain by behaving otherwise. People high in this factor avoid manipulating others for personal gain, feel little temptation to break rules, are uninterested in lavish wealth and luxuries, and feel no special entitlement to elevated social status. People low in this factor are more inclined to flatter or scheme to get what they want, to bend rules for personal benefit, to value money and status highly, and to see themselves as deserving of privilege.
Sincerity measures the tendency to be genuine in relationships rather than manipulative. People high in Sincerity are unwilling to use flattery, charm, or pretense to influence others or win favors, dealing instead in a straightforward way. People low in Sincerity are comfortable telling people what they want to hear and using social tactics to get what they want.
Fairness measures the tendency to avoid fraud and corruption. People high in Fairness are reluctant to take advantage of other people or of society, and resist cheating or stealing even when they could get away with it. People low in Fairness are more willing to bend rules, cut corners, or gain at others' expense for personal benefit.
Greed Avoidance measures the tendency to be uninterested in possessing wealth, luxury goods, and signs of high social status. People high in Greed Avoidance feel little desire for money or lavish things for their own sake. People low in Greed Avoidance are motivated by financial gain and are drawn to expensive possessions and the prestige they signal.
Modesty measures the tendency to be unassuming and to see oneself as ordinary rather than special. People high in Modesty are humble, regard themselves as no better than others, and feel no entitlement to special treatment. People low in Modesty consider themselves superior in some way and feel entitled to privileges and deference that others do not receive.
Emotionality reflects the tendency to experience fear, anxiety, and emotional vulnerability, to feel a need for emotional support, and to form deep sentimental bonds with others. People high in this trait tend to worry about physical and other dangers, feel stressed by hardship, seek closeness and reassurance, and feel strong empathy and attachment toward loved ones. People low in this trait tend to stay calm under threat, feel less swayed by stress, rely on themselves rather than others for support, and feel more emotionally independent from those around them.
Fearfulness measures the tendency to feel fear, to be deterred by physical danger and pain, and to avoid situations that could lead to harm. People high in Fearfulness tend to be cautious, dislike risk, and feel afraid in dangerous or painful circumstances. People low in Fearfulness tend to feel little fear, tolerate pain and danger well, and are willing to take physical risks.
Anxiety measures the tendency to worry, to feel tense and stressed, and to become preoccupied with problems and difficulties. People high in Anxiety tend to worry about many things, feel easily stressed, and find it hard to stop ruminating. People low in Anxiety tend to feel relaxed even under pressure and are not easily troubled by problems.
Dependence measures the need for emotional support from others and the tendency to share one's problems and seek encouragement and reassurance. People high in Dependence tend to want others' comfort and advice when troubled and feel a strong need to be supported. People low in Dependence tend to feel self-sufficient and rarely seek emotional support, handling difficulties on their own.
Sentimentality measures the tendency to feel strong emotional bonds with others, to be moved by others' feelings, and to feel attached and empathetic. People high in Sentimentality tend to form deep emotional connections, feel others' emotions strongly, and are easily touched. People low in Sentimentality tend to feel less emotionally attached and are less affected by others' feelings or by emotional partings.
Extraversion captures engagement with the social world and a person's general sense of energy and positive feeling. It spans how worthy and accepted one feels among others, how confident one is in speaking up and taking the lead, how much one enjoys company and conversation, and how much enthusiasm and cheerfulness one brings to daily life. High scorers feel socially confident, seek out interaction, and tend toward optimism and high spirits. Low scorers feel more reserved and self-conscious in groups, prefer solitude or small circles, and carry a calmer, more subdued mood.
Social Self-Esteem measures a person's sense of worth and acceptance in social settings. High scorers generally feel liked, valued, and at ease in their dealings with others, holding a positive view of themselves as social beings. Low scorers are more likely to feel awkward, unpopular, or of little social value, and may doubt that others regard them favorably.
Social Boldness measures comfort and confidence in social situations that require assertiveness or visibility, such as speaking to a group, leading, or approaching unfamiliar people. High scorers feel at ease taking charge, voicing opinions, and being the center of attention. Low scorers tend toward shyness and reluctance in such roles, feeling more comfortable when others take the lead.
Sociability measures the enjoyment of company, conversation, and social interaction. High scorers actively seek out other people, enjoy talking and socializing, and find solitude less appealing. Low scorers feel little need for frequent interaction, are comfortable on their own, and may find extended socializing tiring rather than refreshing.
Liveliness measures characteristic enthusiasm, energy, and positive feeling. High scorers tend to feel cheerful, optimistic, and high-spirited, bringing visible energy to their activities. Low scorers are typically less exuberant and more subdued in mood, showing calmer, flatter affect rather than open enthusiasm.
Agreeableness reflects how a person tends to respond to others, especially after being wronged or in conflict. It spans willingness to forgive, mildness in judging others, readiness to compromise, and control over temper. Those high in this trait are typically forgiving, lenient, cooperative, and slow to anger; those low in it are more critical, stubborn, quick to feel resentment, and ready to stand their ground. Unlike Big Five agreeableness, the HEXACO version centres on patience and tolerance rather than sentimentality.
Forgiveness reflects how readily a person regains trust and goodwill toward people who have caused them harm. High scorers tend to let go of grudges and grant a second chance, while low scorers are more likely to hold onto resentment and feel that a wrong should not be forgotten.
Gentleness reflects how mild and lenient a person is in dealing with and judging others. High scorers tend to be soft in their criticism and reluctant to judge harshly, while low scorers are more willing to be critical, blunt, and demanding in evaluating the people around them.
Flexibility reflects a person's willingness to compromise and cooperate rather than insist on their own way. High scorers tend to accommodate others and avoid needless argument, while low scorers are more likely to be stubborn, to argue their position, and to resist bending to others.
Patience reflects how readily a person stays calm rather than becoming angry. High scorers tend to keep their composure and are slow to lose their temper, while low scorers are more easily provoked and more likely to react with anger when things go wrong.
Conscientiousness measures how organized, disciplined, careful, and goal-directed a person tends to be. High scorers keep their surroundings and tasks ordered, work hard toward goals, aim for accuracy and quality, and deliberate carefully before acting. Low scorers stay more relaxed about structure and details, feel comfortable with spontaneity and 'good enough,' and act on impulse more readily than they plan everything out.
Organization concerns the tendency to keep things tidy and to approach tasks in a methodical, structured way. High scorers keep their belongings and surroundings in order and like to work to a plan or system. Low scorers feel more comfortable with clutter and tend to tackle things in a more haphazard, as-it-comes manner.
Diligence concerns the drive to work hard and pursue goals with discipline and effort. High scorers push themselves toward their aims, persist through difficulty, and hold a strong work ethic. Low scorers feel less drive to push hard, prefer to take things easy, and stay content to put in only as much effort as feels necessary.
Perfectionism concerns thoroughness and concern for accuracy, detail, and high-quality results. High scorers check their work carefully, attend to small details, and want things done flawlessly. Low scorers stay more tolerant of errors and rough edges, attend less to fine detail, and feel content with results that are simply good enough.
Prudence concerns the tendency to deliberate carefully and control impulses rather than act on the spur of the moment. High scorers think things through, consider consequences, and resist acting rashly. Low scorers act more spontaneously and on impulse, and feel more drawn to immediate rewards than to careful deliberation.
Openness reflects curiosity about ideas, art, and the wider world, along with receptivity to the novel and unconventional. People high in Openness are intellectually inquisitive, drawn to beauty in art and nature, imaginative, and comfortable with the unusual or eccentric. People low in Openness prefer the familiar and practical, feel little pull toward abstract or artistic pursuits, and are content with conventional ideas and routines.
Aesthetic Appreciation reflects how strongly a person is drawn to beauty in art and nature and how absorbed they become in it. High scorers are deeply moved by art, music, and natural scenery and seek out such experiences. Low scorers feel little engagement with the arts or with natural beauty and rarely lose themselves in it.
Inquisitiveness reflects a desire to seek out information about the natural and human world and to learn for its own sake. High scorers are curious about how things work and eager to explore, read, and ask questions across many subjects. Low scorers feel little drive to investigate beyond what their daily life requires.
Creativity reflects a preference for innovation and experimentation and an inclination to generate novel ideas and original work. High scorers enjoy inventing, improvising, and finding unconventional solutions. Low scorers prefer established methods and feel little drive to produce or experiment with original ideas.
Unconventionality reflects a tendency to accept the unusual and an openness to ideas, people, and ways of life that differ from the mainstream. High scorers are receptive to eccentricity and nonconformity and willing to consider strange or radical viewpoints. Low scorers prefer the conventional and feel more comfortable with what is familiar and widely accepted.
Altruism is an interstitial facet that sits between Honesty-Humility, Emotionality, and Agreeableness, loading partly on each rather than on any single factor. It measures a sympathetic, soft-hearted concern for the welfare of others and a reluctance to cause harm. People high in Altruism feel genuine compassion, are moved by others' suffering, and readily help even at some cost to themselves. People low in Altruism are more hard-headed and detached, weighing situations by practical merit and feeling less pulled to step in when others are in need.
Altruism sits between Honesty-Humility, Emotionality, and Agreeableness and isn’t counted toward any single factor.
