Predicting Workplace Delinquency and Integrity with the HEXACO and Five-Factor Models of Personality Structure

Recent lexical studies of personality structure suggest that there are 6, not just 5, basic dimensions of human personality variation. The most distinguishing feature of this new 6-dimensional structure, known as the HEXACO model, is the addition of a new factor named Honesty-Humility. We demonstrate that this new dimension has important implications in personnel psychology. Specifically, the HEXACO model substantially outperformed the Five-factor model (FFM) in predicting workplace delinquency based on samples obtained in 3 different countries, namely, Australia, Canada, and the Netherlands. In addition, the HEXACO model substantially outperformed the FFM in predicting scores on an overt integrity test, due to the inclusion of the Honesty-Humility dimension.
