This research examined the extent to which certainty can strengthen the relationship between individual differences and cheating behavior. In the first two studies, participants completed the Honesty-Humility or the Dark Triad scales. Then, they rated the certainty they had in their responses to each of those two inventories. In the third study, participants completed both scales within the same experimental design and were randomly assigned to a certainty vs. doubt condition. As the dependent variables, we used different cheating outcomes across studies. As predicted, the link between these two traits and cheating behavior was greater for participants with higher levels of certainty in their responses to the inventories (Studies 1 and 2) or for those assigned to the certainty (vs. doubt) condition (Study 3). Incorporating the certainty with which individuals hold their traits contributes to enhancing the predictive validity of personality measures relevant to cheating.

确定性提高了 Honesty-Humility 和 Dark Triad 特征对作弊行为的预测效度


这项研究考察了确定性在多大程度上可以加强个体差异与作弊行为之间的关系。在前两项研究中，参与者完成了诚实-谦逊或黑暗三联征量表。然后，他们对这两个清单的回答中的确定性进行了评级。在第三项研究中，参与者在同一实验设计中完成了两个量表，并被随机分配到确定与怀疑条件。作为因变量，我们在研究中使用了不同的作弊结果。正如预测的那样，对于对清单的反应具有较高确定性的参与者（研究 1 和 2）或被分配到确定性（相对于怀疑）条件的参与者（研究 3），这两个特征与作弊行为之间的联系更大。结合个体保持其特征的确定性有助于提高与作弊相关的人格测量的预测有效性。
