In professional contexts, employees often encounter challenging ethical and compliance dilemmas that may tempt them towards unethical or illegal behavior. Recognizing this, many organizations now provide employees with "contemplation questions" as decision-making aids (e.g., "Would the public approve of my decision?"). However, the effectiveness of such questions remains largely unexplored. In our project, we use incentivized vignettes to examine the effect of different contemplation questions on ethical decision-making. In Study 1, participants were given either no contemplation question or one of 15 different questions before making decisions in various scenarios. Only a few of the questions demonstrated a positive impact on ethical decision-making, with overall marginal effects. Additionally, no effect differences were found between different categories of contemplation questions or conflict types. In an ongoing follow-up study (Study 2), retaining the vignette structure from Study 1, participants initially make decisions without the aid of contemplation questions. Two weeks later, they are then presented with contemplation questions, where they are asked not only to read but also to respond in order to achieve deeper processing before making a final decision. Furthermore, we examine differences based on the wording of contemplation questions and the number of questions. Results for Study 2 are available in early 2024. The project's goal is to gain insights into the mechanisms underlying the effectiveness of contemplation questions and to develop recommendations for their application, selection, and wording.
