15 moral dilemmas that start classic and get increasingly unhinged. Choose wisely. See how the crowd voted. Discover your moral alignment.
The Trolley Problem is a free online interactive thought experiment that presents you with 15 increasingly absurd moral dilemmas. Based on philosopher Philippa Foot's famous 1967 ethical scenario, the game starts with the classic "pull the lever" question and escalates into bizarre, humorous, and genuinely thought-provoking variations. At the end, you see your moral alignment and how your choices compare to other players. In surveys, approximately 85-90% of people say they would pull the lever in the classic scenario.
Each round presents a moral dilemma with two choices. You select your response by clicking one of the two options. After choosing, you see what percentage of other players made the same choice. After all 15 scenarios, the game analyzes your pattern of responses and assigns you a moral alignment label. You can share your results and compare with friends.
The trolley problem is a famous thought experiment in ethics first introduced by philosopher Philippa Foot in 1967. It asks whether you would pull a lever to divert a runaway trolley from killing five people onto a track where it would kill one person. It explores the tension between utilitarian and deontological ethics.
In most studies, approximately 85-90% of respondents say they would pull the lever to save five people at the cost of one. However, in the "fat man" variant where you must push someone off a bridge, only 10-20% say they would act, despite the outcome being mathematically identical.
There is no universally agreed-upon right answer. Utilitarians argue pulling the lever is correct because it saves more lives. Deontologists argue that actively causing harm is always wrong. The trolley problem is valuable precisely because it reveals the tensions in our moral intuitions.
