Moral intuitions are even more unreliable than that. When the “kill one save five” dilemma is presented in the form of pulling a lever to divert a train onto a track with one person on it, most people say to do it. However, when it is presented as pushing a fat man onto the track in order to stop the train, most people say not to do it [1] . The two scenarios are morally identical; the only change is what physical act needs to be done in order to result in the one person getting hit by the train. This demonstrates that we cannot directly consult our intuitions on this question.  [1] Reiner, Peter B., ‘The trolley problem and the evolution of war’, Neuroethics at the core, 11 July 2011,
