Empirical Evidence Reveals the Motivation of Subjects Who Switch Tracks in the Trolley Loop Case

Abstract

This paper investigates the moral intuitions associated with the loop variant of the Trolley Problem, initially proposed by Judith Jarvis Thomson in 1985. Thomson challenged the Doctrine of Double Effect (DDE), which differentiates between intended outcomes and foreseen but unintended consequences. Through an empirical study involving 134 participants from the United States and China, the research explores whether intuitions about the loop variant are influenced by the positioning of track workers and cultural context. The results indicate that a significant number of participants, particularly from China, perceive the permissibility of redirecting the trolley not merely as a means to kill one to save five but as a way to delay the trolley's impact. This suggests that cultural factors and the design of the loop scenario significantly influence moral judgments. The study supports the idea that the loop variant does not serve as a counter-example to DDE, offering insights into the motivations behind moral decisions and highlighting the importance of cultural context in ethical reasoning
