Chidi and Eleanor tackle a famous ethical dilemma, the trolley problem. The thought experiment is popular in philosophy and ethics courses, but the same experiment can be used in an economics context when discussing opportunity costs and costs. In a literal sense, whichever way the trolley goes will have a cost associated with it based on the people who will die. Depending on the structure of your course, you may also be able to look at the trolley problem from a game theory perspective.
