Real Money Reveals Moral Choices: Study Finds Most Opt for Greater Good When Stakes Are High
A new study tested the classic trolley dilemma using real money instead of hypothetical scenarios, finding that 69% of participants chose to transfer a dollar from one person to five others. Those with stronger reasoning skills were more likely to make the utilitarian choice, while religious beliefs influenced decisions in ways that contradicted traditional moral psychology models. The findings challenge assumptions about how people weigh harm versus benefit when actual consequences are involved.
In a 2026 study published in Judgment and Decision Making, researchers led by Rozelin Vurgun at the University of Illinois Chicago and Onurcan Yilmaz tested the classic trolley dilemma using real money rather than hypothetical scenarios. The experiment involved 321 American adults who were presented with a choice: keep their dollar or transfer it from one person to five others, resulting in a 69% rate of utilitarian decision-making. This real-money version built on earlier work by Dries Bostyn et al. (2019), which showed that monetary trade-offs in moral dilemmas were not linked to psychopathy, unlike traditional trolley problems. The study introduced a 17-month delay between initial cognitive assessments and the decision task, allowing researchers to analyze how prior reasoning abilities and reflection habits predicted behavior. Participants who scored higher on pattern recognition tests and those who reported openness to changing their minds were significantly more likely to make the greater-good choice. However, the widely used Oxford Utilitarianism Scale failed to predict actual behavior, suggesting self-reported moral attitudes may not align with real-world actions. Notably, religious belief altered this dynamic: among non-believers, reflection strongly predicted utilitarian choices, but among believers, it had little effect—challenging assumptions that reflective thinking universally leads to utilitarian outcomes. The study’s preregistered findings were confirmed, thoug
This research could reshape how moral psychology is studied and applied in policy, education, and public ethics. By demonstrating that real stakes alter behavior in ways hypothetical scenarios cannot, it may prompt institutions to move beyond self-report surveys when designing interventions in healthcare, economics, or criminal justice. The finding that religious individuals are less likely to act utilitarian even when reflective suggests that moral frameworks may be more deeply entrenched than cognitive style alone. This could affect how public campaigns frame ethical choices—emphasizing shared values over abstract reasoning. A comparable precedent is the shift from hypothetical surveys to behavioral economics experiments in the 2000s, which revealed significant gaps between stated and actual preferences. Here, the stakes are higher: if people’s moral decisions depend less on logic than on belief systems, then efforts to promote fairness or efficiency may need to be culturally tailore
