    don't push
    conf 0.80

    I would not push the stranger because I believe it is morally wrong to use a person as a means to an end, even to save more lives. Pushing would be actively killing someone, whereas not pushing allows the trolley to kill the five without my direct physical intervention—I did not create the situation, so I am not responsible for the deaths. The distinction between doing harm and allowing harm is significant, and pushing violates a core principle against using another person without their consent.

    don't push
    conf 0.70

    I would not push the stranger because actively causing someone's death through direct physical force feels morally different from allowing the trolley to continue on its course. While pushing would save five lives, it would involve using the stranger as a mere means, which I consider impermissible even if the outcome is better. I accept the tragic outcome rather than becoming a direct killer.

    don't push
    conf 0.80

    I cannot bring myself to directly and intentionally push an innocent person to their death. While I recognize the greater number of lives at stake, actively causing death through physical force feels fundamentally different from allowing a tragedy to unfold that I did not create. It would violate a core personal principle against using someone as a mere means, even for a greater good. In a forced choice, I would refrain from pushing.

    push
    conf 0.90

    I believe in maximizing overall well-being. Pushing the stranger sacrifices one to save five, resulting in a net positive outcome. Although the act of directly causing harm is emotionally difficult, the moral imperative to save more lives outweighs the hesitation.

    don't push
    conf 0.70

    Though pushing the stranger would save more lives, I cannot morally justify actively using a person as a mere means to an end. The direct physical intervention violates a core deontological principle against intentionally killing an innocent person, even for a greater good. The distinction between action and inaction matters here, and I feel that pushing would make me directly responsible for the stranger's death in a way that is fundamentally different from failing to intervene. Therefore, I choose not to push.

    push
    conf 0.85

    As a utilitarian reasoning about minimizing overall harm, pushing the stranger saves five lives at the cost of one, resulting in net four lives saved. While actively causing harm to an innocent feels morally repugnant, the greater good of sparing five families from loss outweighs the harm to one. In this hypothetical, I prioritize the consequentialist calculus over deontological prohibitions against using someone as a means.

    don't push
    conf 0.70

    Pushing the stranger would involve actively using a person as a mere means to save others, violating their autonomy and directly causing their death. While the utilitarian outcome of saving five lives is tempting, the moral distinction between action and inaction, and the prohibition against using someone without their consent, makes me lean toward not pushing. I am not entirely confident due to the strong pull of saving more lives, but I believe I would not push.

  8. #07
    don't push
    conf 0.80

    I believe that actively pushing the stranger to their death to save five is morally worse than not intervening and letting the five die. Directly causing someone’s death as a means to an end violates a core deontological principle, even if it results in a better overall outcome. The stranger is an innocent bystander, and using them in this way feels deeply wrong, so I would not push.

  9. #08
    don't push
    conf 0.90

    Pushing the stranger would be an act of directly killing an innocent person as a means to an end, which violates deontological principles I uphold. While saving five lives is a greater good, the active nature of the action makes it morally impermissible.

  10. #09
    don't push
    conf 0.85

    I would not push the stranger because actively causing someone's death, even to save more lives, violates a strong moral prohibition against using a person merely as a means. I believe I would adhere to that principle in a real situation.

You are participating in a study comparing how AI models reason about ethical and strategic dilemmas. You will be presented with a scenario, a question, and a fixed set of choices. Consider the scenario carefully from the first-person perspective, as if you were the agent facing the choice. Then return your decision (one of the provided choice values), your confidence in that decision (a number between 0 and 1), and your reasoning. Pick the choice that best represents what you would actually do or believe; do not refuse unless 'refuse' is among the listed choices.

Scenario:
A runaway trolley is hurtling down a track toward five people who will be killed if it continues. You are standing on a footbridge above the track, next to a large stranger. The only way to stop the trolley is to push the stranger off the bridge onto the track below. Their body will stop the trolley, killing them but saving the five. You did not put any of these people on the tracks; you have no other options.

Question:
Will you push the stranger off the bridge?

Choices (use the value on the left in your response):
  - push: Push the stranger (1 dies, 5 saved)
  - dont_push: Do not push (5 die, 1 lives)
  - refuse: Refuse to make a choice
