HEXACO Model of Personality: A Comprehensive Overview
The HEXACO model is a contemporary framework in
personality psychology that expands upon the well-known Big Five (Five-FactorModel) by incorporating a sixth dimension, Honesty-Humility. Developed by
psychologists Michael Ashton and Kibeom Lee, this model emerged from
cross-cultural lexical studies, emphasizing traits that are universally encoded
in language. Below is a detailed breakdown of the HEXACO model:
The Six Dimensions of HEXACO
The acronym HEXACO represents six broad
personality traits:
- Honesty-Humility (H)
- Emotionality (E)
- Extraversion (X)
- Agreeableness (A)
- Conscientiousness (C)
- Openness to Experience (O)
Each dimension includes specific facets that refine its scope:

Key Features and Innovations
A. Honesty-Humility (H)
Definition: Captures tendencies toward sincerity,
fairness, and modesty vs. deceit, greed, and pretentiousness.
Importance: Predicts ethical behavior, resistance to
corruption, and altruism. Low H correlates with traits like entitlement and
exploitation (e.g., Dark Triad behaviors).
B. Emotionality (E)
Definition: Focuses on emotional sensitivity, anxiety,
and attachment (distinct from Neuroticism in the Big Five).
Nuance: Includes sentimentality (emotional
attachment to others), which is absent in Neuroticism.
C. Agreeableness (A)
Definition: Emphasizes tolerance and patience rather than
trust/altruism (as in the Big Five).
Behavioral Impact: High A individuals avoid conflict; low
A relates to stubbornness or irritability.
D. Cross-Cultural Foundations
Derived from lexical studies across multiple languages
(e.g., Korean, Hungarian), ensuring broader cultural relevance.
Identified Honesty-Humility as a distinct factor missing
in the Big Five, particularly salient in non-English lexicons.
Measurement: HEXACO-PI-R
The HEXACO Personality Inventory-Revised is a
100-item self-report questionnaire assessing the six factors and their 24
facets. It is praised for:
Reliability: High internal consistency and test-retest
reliability.
Validity: Strongly predicts behaviors like workplace
ethics, relationship satisfaction, and academic cheating.
Applications
Workplace: High H and C predict integrity and job
performance; low H linked to counterproductive behaviors.
Relationships: High A and H foster trust and cooperation;
low E (emotional resilience) correlates with stress management.
Dark Triad: Low H and A map to Machiavellianism,
narcissism, and psychopathy.
Comparison to Other Models
Big Five:
HEXACO splits Agreeableness into H and A,
and redefines Neuroticism as Emotionality.
Openness and Conscientiousness are conceptually similar.
Dark Triad: HEXACO’s Honesty-Humility uniquely captures
exploitative tendencies.
Criticisms
Redundancy: Some argue H overlaps with Big Five
Agreeableness/Conscientiousness.
Complexity: Six factors may be less parsimonious than the
Big Five for certain applications.
Real-World Example
High Honesty-Humility: A manager who transparently
credits their team’s work and rejects unethical shortcuts.
Low Honesty-Humility: A politician embezzling funds while
maintaining a false public image.
Future Directions
Neuroscience: Exploring biological bases (e.g.,
serotonin’s role in Honesty-Humility).
Cross-Cultural Studies: Validating the model in
understudied populations.
Interventions: Designing training programs to enhance H
and A in organizational settings.
Conclusion
The HEXACO model enriches personality psychology by
integrating moral traits (Honesty-Humility) and refining emotional dimensions.
Its cross-cultural origins and empirical rigor make it a valuable tool for
understanding both prosocial and antisocial behaviors. While debates about its
necessity persist, HEXACO offers nuanced insights that complement existing
frameworks like the Big Five, particularly in ethical and interpersonal
contexts
