HEXACO is a personality model that expands on the traditional Big Five personality traits. It includes six dimensions: Honesty-Humility, Emotionality, eXtraversion, Agreeableness, Conscientiousness, and Openness to Experience. This model aims to provide a more comprehensive understanding of human personality by incorporating traits related to ethical behavior and interpersonal relationships. The HEXACO model was developed through research that highlighted the importance of Honesty-Humility in predicting behaviors such as altruism and integrity. Each dimension is measured on a continuum, allowing for a nuanced view of personality that can be applied in various fields, including psychology, business, and education.
