Benjamin Hilbig and Ingo Zettler (2009) provide a nice experimental demonstration of this relationship. Participants completed the HEXACO-PI and played a dictator game and an ultimatum game with an initial allocation of 100 points for each game. As expected, those who were higher in honesty-humility gave fewer points to themselves in both games (518). More interesting was the consistency in allocations between the two games. Those lowest in honesty-humility allocated an almost equal amount of points to themselves and the other person in the ultimatum game. But in the dictator game, where there was no threat of rejection by the other person, the average allocation for participants to keep was almost 80 points. By way of contrast, those highest in honesty-humility showed no significant difference in their allocations in the two games. In other words, they were consistently fair, whereas the other group of participants was only being fair when it was to their advantage (518–519).
