<Li> Conscientiousness (C): Organization, Diligence, Perfectionism, Prudence </Li> <Li> Openness to Experience (O): Aesthetic Appreciation, Inquisitiveness, Creativity, Unconventionality </Li> <P> Currently, the most widely used model of personality structure is also based on analyses of personality - descriptive adjectives . This model consists of the five personality factors collectively known as the "Big Five". Three of the Big Five factors are similar to the Extraversion, Conscientiousness, and Openness to Experience factors of the HEXACO model . The two remaining Big Five factors, called Agreeableness and Neuroticism (with the opposite pole of the latter factor being Emotional Stability), are similar to the Agreeableness and Emotionality factors of the HEXACO model--but with some differences in the content of the factors . Agreeableness and Emotionality from the HEXACO model represent rotated variants of their Big Five counterparts, for example, characteristics related to a quick temper are associated with Neuroticism or low Emotional Stability in the Big Five framework, but with low Agreeableness in the HEXACO framework . Therefore, the Big Five's Agreeableness and HEXACO's Agreeableness are not identical . The Big Five factors do not include an Honesty - Humility factor, but some of the characteristics belonging to Honesty - Humility are incorporated into the Big Five's Agreeableness factor . Although earlier investigations found only the Big Five factors, more recent studies conducted in various languages (including English) with larger sets of adjectives recovered six factors, as summarized above . The names of four of the HEXACO factors (all except Honesty - Humility and Emotionality) were adopted from existing labels for the Big Five factors . Factor names were selected on the basis of the common meaning of the characteristics within each factor . </P> <P> The HEXACO model is often used in research studies when behaviours or traits found on the Agreeableness, Honesty - Humility and Emotionality dimensions are of specific interest . The factors of Agreeableness, Honesty - Humility and Emotionality are distinctly different from their counterparts on the Five Factor Model (FFM). Honesty - Humility, Emotionality and Agreeableness are proposed to be measures of Altruistic versus Antagonistic behaviour . Honesty - Humility and Agreeableness both measure two different aspects of Reciprocal altruism, high levels of which indicate a propensity for helping behaviour and cooperation as opposed to the exploitation of others . The Honesty - Humility factor represents a person's tendency for pro-social altruistic behaviours, while Agreeableness indicates an individual's tendency to forgive and to show tolerance . Emotionality is a measure of kin altruism, that is, the tendency to show empathy and attachment to one's kin . </P>
