The HEXACO model of personality structure is a six-dimensional model of human personality that was created by Ashton and Lee and explained in their book, The H Factor of Personality,[1] based on findings from a series of lexical studies involving several European and Asian languages. The six factors, or dimensions, include honesty-humility (H), emotionality (E), extraversion (X), agreeableness (A), conscientiousness (C), and openness to experience (O). Each factor is composed of traits with characteristics indicating high and low levels of the factor. The HEXACO model was developed through similar methods as other trait taxonomies and builds on the work of Costa and McCrae[2] and Goldberg.[3] The model, therefore, shares several common elements with other trait models. However, the HEXACO model is unique mainly due to the addition of the honesty-humility dimension.[4]
