The trolley problem is a classic thought experiment that evokes an ethical dilemma. Thomson’s “bystander” and “footbridge” versions of the trolley problem induce different intuitive judgments about what to choose in the ethical dilemma. However, we can question how robust these intuitive judgments are. We thus conducted an online survey experiment of Thomson’s versions of the trolley problem which showed that more respondents tended to choose not pulling the lever in the bystander version and pushing a person off the bridge in the footbridge version when they believed they were not being watched. These results illustrate that people’s decisions deviate from the social norms in the absence of the public’s attention. To activate the practice of holding the manufacturers to a normative expectation based on the social norms, we suggest the law must be changed.

The issue of distributive justice receives substantial amount of attention in our society. On the one hand, we are sensitive to whether and the extent to which people are responsible for being worse off. On the other hand, we are mindful of society’s worst-off members. There has been a debate over luck egalitarianism, which relates to the former concern, and relational egalitarianism, which echoes the latter. By investigating the psychological processes of these two concerns, this paper examines the reliability of the argument that Elizabeth Anderson, a renowned relational egalitarian, presents against luck egalitarianism and for relational egalitarianism. It also considers whether it is possible to support luck egalitarianism and relational egalitarianism simultaneously, using an online experiment. The results of the experiment show that, first, for ordinary people, the luck consideration is as important as the basic capabilities consideration. Second, while real people consider the degree of compensation through the factors of causality and responsibility, the lack of basic capabilities directs them to determine how much victims of bad luck should be compensated. This suggests that pluralist egalitarianism is on the right track.
