Personality psychology aims to classify and explain human traits, and one of the most comprehensive models for understanding personality is the HEXACO model. This framework expands upon the widely used Big Five personality traits, adding an essential dimension: Honesty-Humility.
Developed by Kibeom Lee and Michael Ashton, the HEXACO model is based on factor analysis of personality descriptors across multiple languages. It provides a detailed picture of human behavior, motivation, and interpersonal relationships.
This article explores the six personality dimensions of the HEXACO model, its differences from other theories, and its applications in psychology.
The HEXACO model is a personality framework that identifies six core dimensions of human personality, each represented by a broad trait with sub-traits (facets). The name HEXACO is an acronym formed from the six primary dimensions:
Honesty-Humility (H)
Emotionality (E)
eXtraversion (X)
Agreeableness (A)
Conscientiousness (C)
Openness to Experience (O)
This model differs from the Big Five Personality Traits by incorporating Honesty-Humility, which assesses sincerity, fairness, and modesty, making it particularly relevant in understanding moral and ethical behavior.
HEXACO personality model
The first thing that draws “attention” about the HEXACO personality model is that it has 6 basic factors, one for each letter of your name, which refer to the different traits or factors that are included in it. In this way, it proposes: honesty-humility (H), emotionality (E), extraversion (X), cordiality (A), conscientiousness (C) and openness to experience (O); forming the acronym by which it has been popularized and outlining a series of dimensions in which any human being can be located. It is, therefore, about a spectrum of intensity that includes “normal” and “pathological” personality (which predisposes to mental health problems).
As can be seen, this theoretical model represents an increase in the number of factors compared to Eysenck’s classic three-dimensional postulate (neuroticism, extraversion and psychoticism) and Costa and McCrae’s five-dimensional, which became known as the Big Five (neuroticism, extraversion, openness to experience, agreeableness and responsibility). The latter became, without a doubt, the most used by the entire scientific community; although in recent years it has been receiving numerous criticisms for its inability to explain the complete variance of human diversity.
The HEXACO model, like the “Big Five”, was built from an analysis of the lexicon with which people described the forms that personality could take. That is, a sample of multiple languages was used, and from its analysis the words that served to define the behavior of human beings were extracted, observing a consensus between cultures that could be summarized in the 6 factors finally included in HEXACO. Of all of them, the most relevant were neuroticism and extraversion, which also emerged as those with the greatest predictive power regarding emotional difficulties.
And one of the great purposes of personality models is to find, at least, protective and risk factors for the emergence of various psychopathologies. Underlying all of this would be the interest in knowing the way in which human beings act and think when relating to other people in their environment or with themselves, since from there it would be possible to predict and explain the nuances of their emotional and intimate life. All of this is very important when designing intervention programs that take into account individuality and adjust to the idiosyncrasy of the patient.
The most important contribution of HEXACO is the honesty-humility factor, for which there was no analogue until now in previous personality models. Furthermore, it renames neuroticism (labeling it as emotionality) and incorporates sentimentality as a facet of it (previously included in agreeableness). The redistribution of the facets of each factor also extends to anger control, which was traditionally part of neuroticism and with HEXACO is reassigned to agreeableness. The rest of the factors (both extraversion, openness to experience and conscientiousness) remain very similar in their formulation.
There is currently a questionnaire purposely designed to explore the factors outlined and called HEXACO-PI (whose review was carried out in 2006). It has three different versions, depending on the total number of items included; It may consist of 200, 100 or 60 reagents. The last two are the most widely used, since they have similar reliability (very good/excellent) and are less expensive to administer. In addition, they have an additional advantage: they can be answered by the person themselves or by a family member or friend who knows them well.
The 6 Components of the HEXACO Model
1. Honesty-Humility (H)
This dimension reflects a person’s tendency to be sincere, fair, and avoid manipulation for personal gain.
High Honesty-Humility
Avoids exploiting others
Sincere and fair-minded
Uninterested in material wealth or social status
Modest and unassuming
Low Honesty-Humility
Manipulative or deceptive
Greedy and materialistic
Prone to narcissism, psychopathy, and Machiavellianism
More likely to break ethical rules
🔹 Why It Matters: This trait is crucial in predicting moral and ethical behavior, influencing areas like leadership, criminality, and workplace integrity.
Similar to Neuroticism in the Big Five but with some differences, Emotionality refers to a person’s sensitivity to emotions, stress, and relationships.
High Emotionality
Strong attachment to loved ones
Prone to anxiety and fear
Sensitive and empathetic
Worries about safety and well-being
Low Emotionality
Less emotionally reactive
Independent and self-reliant
Less prone to anxiety or stress
Less sentimental
🔹 Why It Matters: Emotionality influences how people cope with stress, trauma, and social connections, impacting mental health and relationships.
3. eXtraversion (X)
Extraversion reflects how much a person enjoys social interaction, excitement, and assertiveness.
High Extraversion
Outgoing and sociable
Energetic and confident
Enjoys leadership roles
Thrives in stimulating environments
Low Extraversion (Introversion)
Reserved and quiet
Prefers solitary activities
Less dominant in social settings
Enjoys deep conversations over small talk
🔹 Why It Matters: This trait influences social behavior, leadership, and career success, helping determine if someone is energized by people or solitude.
4. Agreeableness (A)
Agreeableness refers to a person’s cooperativeness, patience, and tolerance in social interactions. However, HEXACO’s Agreeableness is different from the Big Five, as it focuses more on forgiveness, patience, and tolerance for conflict.
High Agreeableness
Forgiving and tolerant
Avoids unnecessary conflict
Patient and understanding
Cooperative in social settings
Low Agreeableness
Easily irritated or confrontational
Holds grudges
More competitive than cooperative
Less likely to back down from conflict
🔹 Why It Matters: Agreeableness affects relationship quality, teamwork, and conflict resolution, playing a major role in personal and professional interactions.
5. Conscientiousness (C)
Conscientiousness measures self-discipline, organization, and goal-directed behavior.
High Conscientiousness
Hardworking and disciplined
Organized and detail-oriented
Sets and achieves long-term goals
Avoids impulsive behavior
Low Conscientiousness
Disorganized and careless
Struggles with self-discipline
Impulsive and easily distracted
Less goal-driven
🔹 Why It Matters: Conscientiousness is linked to academic and career success, as well as physical health and longevity, due to its association with self-control.
6. Openness to Experience (O)
Openness reflects intellectual curiosity, creativity, and willingness to try new experiences.
High Openness
Curious and imaginative
Open to new ideas and cultures
Enjoys art, music, and literature
Loves abstract thinking and deep discussions
Low Openness
Prefers routine and familiarity
Less interested in abstract ideas
Practical rather than imaginative
Less likely to seek out new experiences
🔹 Why It Matters: Openness is linked to creativity, problem-solving, and adaptability, making it essential for artistic, scientific, and intellectual pursuits.
Lines of investigation
The HEXACO personality model currently enjoys a large volume of research; as it is considered very precise in describing patterns of behavior, thought and affect. In addition, the effect of the opposite poles is being studied for each of the factors that compose it, given that due to their dimensional nature they can be evaluated as spectra with their own dichotomous extremes.
In this way, the model allows you to explore the impact of arrogance, stability of emotions, introversion, irresponsibility, irritability, etc (specular factors of each of the large dimensions). Its use is extending to contexts as varied as health self-care, addictive behavior, general psychopathology and any other imaginable area in which personality may play a potentially relevant role. It is, therefore, a valuable contribution to psychological science whose fruits will allow progress towards a greater understanding of human beings.
How Is the HEXACO Model Different from the Big Five?
While the Big Five and HEXACO models share many similarities, the main difference is the addition of the Honesty-Humility factor in the HEXACO model.
Key Differences:
Honesty-Humility is absent in the Big Five but included in HEXACO.
HEXACO’s Agreeableness focuses more on patience and forgiveness than conflict avoidance.
HEXACO’s Emotionality differs from Neuroticism by emphasizing attachment and dependence.
🔹 Why It Matters: HEXACO provides a better explanation of ethical behavior, moral decision-making, and social cooperation, making it useful in personality assessment, job recruitment, and psychological research.
Applications of the HEXACO Model
