Creativity research has suggested that creative people are low in agreeableness. To explore this issue, we applied the HEXACO model of personality structure, which offers an expanded representation of interpersonal traits, particularly a distinction between Honesty–Humility and Agreeableness. A sample of 1304 adults completed the HEXACO-60 and several measures of creative achievement and activities. Latent variable models found that Agreeableness had no relationship with creativity, but Honesty–Humility did: people lower in Honesty–Humility had higher creativity scores, consistent with past work on arrogance and pretentiousness among creative people.Highlights► The HEXACO structure of creativity was examined. ► Young adults completed the HEXACO-60 and a broad range of self-report measures of creativity. ► Agreeableness was unrelated to creativity, and Honesty–Humility was negatively related to creativity. ► The HEXACO model offers a more refined view of interpersonal aspects of creativity.
