Research on commercial computer games has demonstrated that in-game behavior is related to the players' personality profiles. However, this potential has not yet been fully utilized for personality assessments. Hence, we developed an applied (i.e., serious) assessment game to assess the Honesty-Humility personality trait. In two studies, we demonstrate that this game adequately assesses Honesty-Humility. In Study 1 (N = 116), we demonstrate convergent validity of the assessment game with self-reported Honesty-Humility and divergent validity with the other HEXACO traits and cognitive ability. In Study 2 (N = 287), we replicate the findings from Study 1, and also demonstrate that the assessment game shows incremental validity-beyond self-reported personality-in the prediction of cheating for financial gain, but not of counterproductive work and unethical behaviors. The findings demonstrate that assessment games are promising tools for personality measurement in applied contexts.
