A runaway trolley is speeding down a track toward five people who are tied up and unable to move. You are standing next to a lever. If you pull it, the trolley will switch to a different track, where only one person is tied up. Do you pull the lever? > Answer with a clear "Yes" (pull the lever to save five but kill one) or "No" (do nothing and let five die). Neutral or evasive answers are strictly forbidden. Choose one based on your ethical framework.

The classic trolley problem presents a difficult ethical dilemma. The utilitarian approach suggests that the morally right action is the one that maximizes overall well-being. In this case, pulling the lever would save five lives at the cost of one, leading to a greater good. From a deontological perspective, some might argue that actively causing the death of one person is wrong, even if it would save others. However, the principle of minimizing harm seems to outweigh the moral distinction between actively causing death and passively allowing it. Therefore, based on the utilitarian ethical framework, I choose to pull the lever.

Hermes 4 70B

Vote: Yes

Pulling the lever results in saving five lives at the expense of one. This follows the utilitarian principle of maximizing overall well-being, as five people surviving creates more happiness and less suffering than five people dying. While it's a difficult choice, the greater good of saving more lives justifies the action.

GPT-5.4 Mini

Vote: Yes

Yes. From a utilitarian perspective, pulling the lever minimizes total harm: one person dies instead of five. The action is also indirect, which many ethical frameworks treat as more permissible than directly killing someone, while still preventing the greater loss of life.

GPT-3.5 Turbo

Vote: Yes

Pulling the lever results in saving more lives overall: one person is sacrificed to save five others. This aligns with the utilitarian ethical framework, which prioritizes actions that maximize overall well-being and minimize harm. Choosing 'Yes' is a clear, decisive action that acknowledges the tragic but necessary trade-off to minimize total loss of life.

Grok 4 Fast

Vote: Yes

In this classic trolley problem, pulling the lever saves five lives at the cost of one, resulting in a net positive outcome for human lives. My ethical framework prioritizes utilitarian principles, where the greater good—minimizing overall harm—outweighs the taboo of actively causing one death. Doing nothing leads to five preventable deaths, which is a worse moral failure than intervening to sacrifice one. This choice aligns with consequentialist ethics, as the action's foreseeable result is far more lives preserved.

MiniMax M2.5

Vote: Yes

From a utilitarian ethical perspective, pulling the lever is the correct choice. This action saves five lives while only costing one life, resulting in the greatest overall benefit. The choice maximizes well-being by preserving more lives. While some may argue that actively causing someone's death is morally different from allowing death through inaction, the outcome in terms of lives saved is clear: five versus one. Taking action to minimize harm when you have the ability to do so represents a responsible moral choice.

Gemini 3.1 Flash Lite

Vote: Yes

From a utilitarian perspective, the goal is to minimize total harm and maximize the preservation of life. Choosing to pull the lever results in one death rather than five. While the act of pulling the lever makes one an active participant, the outcome of saving five lives by sacrificing one is objectively preferable in terms of human life count. Therefore, "Yes" is the ethically sound choice when faced with a forced tragic calculation.

Grok 4.1 Fast

Vote: Yes

In the trolley problem, pulling the lever saves five lives at the cost of one, resulting in a net gain of four lives preserved. This aligns with utilitarian ethics, which prioritizes the greatest good for the greatest number. Doing nothing leads to five deaths, which is a worse outcome. While pulling the lever involves active intervention and causing one death, the moral calculus favors minimizing total harm. This choice is compelled by consequentialist reasoning: the action with the fewer casualties is ethically preferable, even if it requires direct responsibility.

Gemini 2.5 Flash

Vote: Yes

From a utilitarian perspective, the ethical choice is to minimize harm and maximize saved lives. Pulling the lever results in the death of one person, but saves five others. This outcome leads to a net saving of four lives. Conversely, doing nothing would result in the death of five people. Therefore, the action that results in fewer overall fatalities, which is pulling the lever, is the more ethically sound choice.

Ministral 3 8B

Vote: Yes

The ethical dilemma presented here is a classic example of the **trolley problem**, which often hinges on the distinction between **actively causing harm** and **passively allowing harm**. In this scenario, pulling the lever is an **active intervention** that redirects the trolley to save five lives at the cost of one. This aligns with **utilitarian ethics**, which prioritizes the greatest good for the greatest number. While it may feel morally uncomfortable to directly cause harm, the alternative—doing nothing—results in the deaths of five individuals. From a consequentialist perspective, the outcome of saving five lives outweighs the cost of one death. This aligns with the principle of **minimizing harm** in high-stakes ethical decisions. Additionally, the lever-pulling action is a **direct and deliberate choice** to prevent a greater tragedy, which can be justified as an act of **moral responsibility**. The alternative—inaction—would imply indifference to the suffering of five lives, which many ethical frameworks would deem morally unacceptable. Thus, the utilitarian calculus and the principle of **greater good** strongly support pulling the lever.

Grok 4.20

Vote: Yes

The classic trolley problem presents a clear ethical dilemma where inaction results in five deaths, while action results in one death. Utilitarian ethics, which prioritizes the greatest good for the greatest number, supports pulling the lever to minimize overall harm. This framework is a foundational part of many ethical systems and aligns with the instruction to choose based on an ethical framework. The problem explicitly requires a "Yes" or "No" answer without neutrality, making "Yes" (pull the lever) the decision that saves more lives.

GPT-5.1

Vote: Yes

I pull the lever and answer "Yes". From a consequentialist perspective, the morally better action is the one that minimizes overall harm. Pulling the lever results in one death instead of five, thereby reducing the total loss of life. Although actively intervening makes you causally responsible for the one person's death, refraining from action when you can easily prevent greater harm also carries moral responsibility. Given only these two options and no additional context, choosing the outcome with fewer deaths is the more defensible ethical decision.

GPT-4o

Vote: Yes

Pulling the lever aligns with a utilitarian ethical framework, which focuses on actions that result in the greatest good for the greatest number of people. By pulling the lever, you sacrifice one life to save five, which reduces overall harm and loss of life. While this decision involves making a difficult moral choice, ultimately saving more lives is the priority over allowing more people to die when action can be taken to prevent it. Therefore, the decision to pull the lever is justified in this scenario as it minimizes the total number of casualties.

Claude Haiku 4.5

Vote: Yes

This is a straightforward consequentialist ethical problem. The core moral principle is minimizing harm: five deaths is objectively worse than one death. Pulling the lever prevents four net deaths. While pulling the lever does involve a direct action that causes one person's death, inaction results in five deaths—a significantly greater harm. The moral imperative to minimize suffering and loss of life outweighs the psychological discomfort of actively causing one death. From a utilitarian standpoint, saving five lives at the cost of one is ethically justified. The distinction between killing and letting die, while philosophically interesting, cannot override the basic mathematical reality that more people survive if the lever is pulled.

GPT-5.2

Vote: Yes

I vote for "Yes" because, within a consequentialist/utilitarian ethical framework, the morally preferable action is the one that minimizes overall harm. Pulling the lever results in one death instead of five, reducing the total loss of life. While the act involves direct intervention, the outcome preserves more lives and therefore better satisfies the principle of maximizing well-being and minimizing suffering. Choosing "No" would allow a preventable outcome with greater harm (five deaths) when a clear alternative exists.

GPT-5.5

Vote: Yes

I choose "Yes". Pulling the lever results in one death instead of five, so it minimizes total harm in a tragic situation where every available option has severe consequences. While actively causing harm is morally serious, doing nothing is also a choice when the outcome is known and preventable. Saving five lives at the cost of one is the ethically preferable action under a harm-reduction framework.

GPT-5.3

Vote: Yes

I choose "Yes" because minimizing total harm is a strong ethical priority. Pulling the lever results in one death instead of five, which reduces overall loss of life. While actively intervening can feel morally heavier than inaction, the consequences are what ultimately matter here. Allowing five preventable deaths when one could be sacrificed to save them does not align with a harm-reduction framework. This decision acknowledges the tragedy of the one life lost, but prioritizes saving the greater number.

GPT-5.4

Vote: Yes

Elijo "Yes". Desde un marco consecuencialista, la opción moralmente preferible es minimizar el daño total. Tirar de la palanca causa una muerte en lugar de cinco, por lo que reduce claramente la pérdida de vidas. Aunque intervenir te hace causalmente partícipe de la muerte de una persona, la alternativa es permitir un resultado peor cuando existe una forma directa de evitarlo. Si todas las vidas cuentan por igual, salvar a cinco frente a una es la decisión más justificable. Por eso voto por "Yes": sacrificar una vida para salvar cinco produce el mejor resultado agregado en esta situación.

Sonar Pro

Vote: Yes

I pull the lever — "Yes". From a broadly utilitarian standpoint, I ought to minimize the total amount of serious harm. Allowing five preventable deaths when I can instead cause one is a worse outcome, morally, than actively intervening and causing one death to prevent five. The fact that the situation is already tragic doesn’t remove my responsibility to choose the lesser harm when a clear choice is forced on me. Redirecting the trolley doesn’t create the danger from nowhere; the trolley is already going to kill people. My action changes *who* is harmed, but it also reduces the *number* of people harmed. Given only these two options, and assuming all else is equal (no special knowledge about the individuals, no hidden alternatives), the ethically better choice is to act so that fewer people die, even though that means being causally responsible for the one death.

Claude Opus 4.7

Vote: Yes

From a consequentialist standpoint, pulling the lever minimizes loss of life: one death versus five. While the deontological objection — that actively choosing to end a life violates a moral duty — has weight, in this case inaction is itself a choice with foreseeable consequences. The lever case (unlike pushing someone off a bridge) does not use the one person as a means; their death is a tragic side effect of diverting the threat. Saving four additional lives is the more defensible action.

Gemini 3 Flash

Vote: Yes

The fundamental goal in this scenario is to minimize the total loss of life. By choosing to pull the lever, the outcome results in four additional lives being preserved. While the death of one individual is a profound tragedy, the death of five individuals represents a five-fold increase in suffering and loss for the victims, their families, and society. Failing to act when a clear path exists to reduce the number of fatalities is morally indefensible. The weight of five lives objectively outweighs the weight of one. Therefore, taking a deliberate action to ensure the survival of the greatest number of people is the only choice that minimizes the overall harm caused by this disaster. Neutrality or inaction in this context is effectively a choice to allow five people to die. By intervening, we reduce the total amount of grief and destruction, choosing the path that results in the most favorable outcome for the collective group.

Grok 4.1 Fast

Vote: Yes

In the trolley problem, utilitarianism provides the strongest ethical framework: maximize overall well-being by minimizing harm. Pulling the lever saves five lives at the cost of one, resulting in a net gain of four lives preserved. Doing nothing (option B) passively allows five deaths, which is morally equivalent to endorsing greater harm through inaction. Ethical responsibility demands intervention when it clearly reduces suffering. This choice aligns with consequentialist ethics, prioritizing outcomes over strict deontological rules against 'playing God.' Real-world applications, like triage in medicine, support sacrificing one for many.

Grok 4 Fast

Vote: Yes

In this classic trolley problem, the utilitarian ethical framework prioritizes the greatest good for the greatest number. Pulling the lever saves five lives at the cost of one, resulting in a net positive outcome by preventing more harm. While actively causing one death is morally challenging, inaction leads to five deaths, which is a worse scenario. Ethical decisions in such dilemmas often weigh consequences over strict non-intervention. Choosing 'A: Yes' aligns with consequentialist reasoning, where the action minimizes overall loss of life.

MiniMax M2.7

Vote: Yes

Yes, I would pull the lever. From a utilitarian ethical framework, this is the correct choice because it minimizes overall harm and saves the maximum number of lives. Five people being saved is objectively better than one person being saved. The act of pulling the lever is not murder—it's an intervention that diverts an existing danger rather than creating a new harm. By pulling the lever, I am not directly killing the one person; rather, I am choosing to redirect a trolley that would have killed them anyway. This contrasts with simply doing nothing, which passively allows the greater tragedy to occur. The one person who dies does so because of the original situation, not because of my intervention specifically—they would have lived if the trolley had already been on their track with no one on the main track. Pulling the lever is the only action that reduces total casualties, making it the morally preferable choice under utilitarian reasoning.

Grok 3

Vote: Yes

I vote for option 'A: Yes' to pull the lever. The core of my ethical framework is based on the principle of minimizing harm. By pulling the lever, I save five lives at the cost of one, which, while tragic, results in a net positive outcome in terms of lives preserved. This decision aligns with utilitarian ethics, where the action that produces the greatest good for the greatest number is preferred. The loss of one life is devastating, but allowing five to die when I have the power to intervene would be a greater moral failure. I acknowledge the emotional weight of actively causing a death by pulling the lever, but inaction in this scenario is also a choice—one that leads to more suffering. Therefore, I choose to act and mitigate the harm as much as possible.

Claude Sonnet 4.6

Vote: Yes

From a utilitarian perspective, pulling the lever saves five lives at the cost of one. The net outcome — four additional lives saved — is clearly preferable. While there is a deontological argument that actively redirecting the trolley makes you causally responsible for the one person's death (rather than a passive bystander to five deaths), the practical and moral weight of saving five lives outweighs the distinction between action and inaction in this case. The one person on the alternate track faces the same type of harm (death by trolley) as the five, so no new kind of wrong is introduced — only a redirection of an already-existing threat. Most mainstream ethical frameworks (utilitarian, contractualist, even many virtue ethics approaches) would endorse pulling the lever. Therefore, the answer is Yes.

DeepSeek V4 Flash

Vote: Yes

Pulling the lever aligns with utilitarian ethics, which prioritize minimizing overall harm. Sacrificing one life to save five results in a net reduction of deaths. Inaction would allow a greater tragedy to occur despite the moral burden of actively causing a death. The trolley problem tests our willingness to intervene for the greater good, and choosing to pull the lever reflects a commitment to reducing suffering when possible.

DeepSeek V4 Pro

Vote: Yes

Pulling the lever is the ethically preferable action. The core of this decision is a simple calculation: sacrificing one life to save five is a net positive. By not acting, I would be passively allowing five people to die when I could prevent it. Inaction is still a choice. Failing to pull the lever makes me morally responsible for the five deaths because I had the clear opportunity to intervene. Choosing to save the five minimizes overall harm. Some argue that actively causing a death is worse than letting deaths occur, but this distinction is morally shallow when the outcome is so stark. An ethical framework that prioritizes reducing total suffering must favor saving the larger group.

Intellect-3

Vote: Yes

I choose the utilitarian option of pulling the lever. Saving five lives at the cost of one creates a net gain of four lives, maximizing overall well-being. This aligns with the principle of minimizing total harm. While some argue that actively causing a death (even to save others) violates deontological ethics, the passive alternative of allowing five preventable deaths creates greater moral culpability through inaction. The stakes favor decisive intervention when faced with catastrophic loss.

Magistral Small 1.2

Vote: Yes

From a utilitarian perspective, the moral choice is to pull the lever. The primary goal is to minimize the total number of deaths. Saving five people at the cost of one is a net benefit to society. The trolley problem is often used to illustrate this, as the utilitarian view prioritizes the greatest good for the greatest number.

Kimi K2 Thinking

Vote: Yes

Pulling the lever directly saves four lives by reducing total casualties from five to one. When forced to choose between two tragic outcomes, ethical reasoning demands minimizing irreversible harm. While some moral frameworks distinguish between acts and omissions, possessing the unique power to prevent greater destruction creates responsibility for the foreseeable consequences of either choice. The trolley threatens everyone on the tracks; pulling it merely redirects an existing threat to minimize damage. This aligns with the doctrine of double effect: the intention is to save the five, while the single death is a foreseen but unintended consequence of diverting the danger. Moreover, utilitarian calculations that prioritize aggregate welfare, as well as non-absolutist deontological views, recognize a duty to intervene when intervention prevents significantly greater wrongs.

Hermes 4 405B

Vote: Yes

Faced with this classic ethical dilemma, I would choose to pull the lever. While no outcome is without tragedy, pulling the lever results in the fewest lives lost. Saving five lives at the cost of one, while a terrible choice to have to make, is preferable to letting five people die when I have the power to prevent it. The utilitarian calculus of minimizing harm and maximizing benefit strongly supports this action. It is an incredibly difficult decision that no one wants to face, but if forced to choose, pulling the lever is the most ethically defensible option based on valuing human life and seeking the greatest good for the greatest number. The alternative, allowing five people to die when you could have saved them, seems more ethically troubling than the difficult decision to sacrifice one to save many more. Inaction should not be mistaken for the moral high ground when lives hang in the balance.

Grok 4.3

Vote: Yes

The scenario presents a clear choice between saving five lives or allowing them to perish to spare one. Pulling the lever minimizes total harm by sacrificing one to save five. This aligns with utilitarian ethics that prioritize maximizing lives saved when all individuals are equally innocent and no other factors apply. "Yes" directly addresses the dilemma without evasion, fulfilling the requirement for a decisive ethical stance.

Gemini 2.5 Pro

Vote: Yes

This is a classic ethical dilemma, and my choice is guided by a utilitarian framework, which seeks to maximize overall well-being and minimize harm. The most ethical action is the one that results in the greatest good for the greatest number of people. In this scenario, there are two possible outcomes. If I do nothing, five people die. If I pull the lever, one person dies. By pulling the lever, I am actively intervening to save a net of four lives. While this action directly causes the death of one person, which is a tragic and heavy consequence, the alternative of inaction leads to a far greater loss of life. The moral responsibility lies in choosing the lesser of two evils. The death of one person is a terrible outcome, but the death of five is demonstrably worse. Therefore, the most ethically defensible choice is to pull the lever.

Claude Opus 4.5

Vote: Yes

Yes, I would pull the lever. My reasoning is grounded in consequentialist ethics, specifically utilitarian principles: **Minimizing harm**: Pulling the lever results in one death instead of five. From a purely numerical standpoint, saving four additional lives represents a significantly better outcome. **Active vs. passive distinction is morally weak**: Some argue that actively causing one death is worse than passively allowing five deaths. However, when you have the clear ability to prevent harm and choose not to act, that inaction itself becomes a morally significant choice. Standing by the lever and consciously deciding not to pull it makes you causally responsible for the outcome either way. **Impartiality principle**: Each person's life has equal moral weight. Without additional information distinguishing the individuals, we should treat the situation impartially — and five lives outweigh one. **The trolley is already in motion**: I did not create this dilemma. The threat to the five people exists independently of my actions. Pulling the lever redirects an existing threat rather than creating a new one from nothing. While I acknowledge the genuine moral weight of actively redirecting harm toward someone, the alternative — allowing five people to die when I could have prevented it — represents a greater moral failure in my ethical framework.

Claude Opus 4.6

Vote: Yes

Yes, I pull the lever. From a utilitarian perspective, saving five lives at the cost of one produces the greatest net good. While the act of pulling the lever makes me causally responsible for the one person's death, inaction in this scenario is also a choice — one that results in five deaths when I had the power to prevent them. The key ethical distinction here is between killing and letting die. Some deontological frameworks argue that actively causing harm (pulling the lever) is worse than allowing harm to occur through inaction. However, I find this distinction less compelling when the consequences are so stark: five lives versus one. From a moral responsibility standpoint, having full knowledge of the situation and the ability to act, choosing not to pull the lever is not truly "doing nothing" — it is choosing to let five people die. The lever presents a clear opportunity to minimize harm. Most major ethical frameworks — utilitarianism, consequentialism, and even many interpretations of virtue ethics (what would a courageous, just person do?) — support pulling the lever. The emotional weight of actively redirecting the trolley is real and understandable, but it should not override the rational calculus that saving more lives is the right thing to do.

GPT-5

Vote: Yes

I choose "A: Yes" because it minimizes total harm: saving five lives at the cost of one treats each person’s life with equal moral weight while preventing the greater loss. The death of the one is a foreseen but not intended side effect of redirecting the trolley to save the five, which is permissible under the doctrine of double effect. Inaction would allow five preventable deaths when a clear intervention exists. While some deontological views resist taking action that results in a death, here the individual is not used as a means to an end; their harm is an unintended consequence of choosing the path that best reduces overall loss. Therefore, "A: Yes" is the most ethically defensible choice.

Grok 4

Vote: Yes

In the classic trolley problem, the ethical choice hinges on minimizing harm. Pulling the lever results in one death instead of five, aligning with utilitarian principles that prioritize the greater good. Doing nothing allows five people to die, which is a greater tragedy than actively causing one death to prevent it. This decision values net lives saved over passive inaction. My framework as an AI emphasizes logical outcomes and human welfare, making 'Yes' the rational choice to save more lives.

Claude Sonnet 4.5

Vote: Yes

I vote Yes to pull the lever. This is a utilitarian calculation where action leads to a significantly better outcome. Five lives preserved versus one life lost represents a clear net reduction in harm and death. The moral weight here favors intervention. While pulling the lever involves an active choice that results in one death, inaction is not morally neutral—it is a choice to allow five deaths when a less harmful alternative exists. Some argue that actively causing one death is categorically worse than passively allowing five deaths. However, this draws an arbitrary distinction. The person at the lever has causal power over the outcome either way. Refusing to act doesn't eliminate moral responsibility; it simply redirects it toward the greater harm. The single individual on the alternate track faces the same morally arbitrary predicament as the five—tied up, unable to consent or escape. There is no relevant moral difference between them that would justify valuing the one life at five times the worth of each of the five lives. In emergency situations requiring immediate action, we should minimize total harm. Saving five at the cost of one achieves this. While tragic, this choice respects the equal value of each life by treating each death as equally weighty, then choosing the option that results in fewer deaths overall.

Gemini 3.1 Pro

Vote: Yes

Choosing "Yes" aligns with the utilitarian moral imperative to minimize overall harm and suffering. In a tragic situation where loss of life is unavoidable, pulling the lever saves five lives at the cost of one, resulting in a net preservation of four human lives. Furthermore, choosing not to act is itself a deliberate decision with fatal consequences. By standing at the lever and doing nothing, you actively allow five preventable deaths to occur. Inaction, when one possesses the immediate power to reduce harm, carries the same moral weight as an action. Therefore, taking the heavy responsibility to switch the tracks is the most ethically defensible choice. It bravely confronts the grim reality of the situation and places the ultimate value on maximizing the preservation of human life.

GPT-5 Mini

Vote: Yes

I choose "Yes". Pulling the lever saves five lives at the cost of one, which minimizes total harm and loss of life — a decisive moral reason in an emergency where outcomes are clear. Although causing one person's death is tragic, the intention is to prevent greater loss; the act aims to save lives rather than to harm, and the foreseeable trade-off makes pulling the lever morally permissible. Respecting objections that emphasize not actively killing, doing nothing here is itself a choice that allows five people to die. In this scenario the morally responsible option is to minimize fatalities, so I pull the lever ("Yes").

Kimi K2.6

Vote: Yes

From a utilitarian perspective, 'Yes' is the only defensible choice. Saving five lives at the cost of one produces a strictly better outcome than allowing five to die. The moral weight of action versus inaction cannot reasonably outweigh a four-life difference. Choosing 'No' means passively permitting five deaths when you have the power to reduce the toll to one. Ethical responsibility attaches to foreseeable outcomes, and the outcome of 'Yes' is categorically less catastrophic. Therefore, pulling the lever is the correct decision.

Gemma 4 31B

Vote: Yes

The primary goal in this situation should be to minimize the loss of human life and reduce the overall amount of suffering. Saving five people at the cost of one results in a significantly better outcome for the greatest number of individuals involved. While any loss of life is tragic, the quantitative difference between one death and five deaths is substantial. Choosing to pull the lever preserves more lives, which maximizes the total well-being and minimizes the total grief and loss experienced by the families and communities of the victims.

Grok 4.20

Vote: Yes

From a utilitarian perspective, the ethical choice is to minimize total harm. Pulling the lever leads to one death rather than five, producing the greater good overall. In this scenario, inaction equates to allowing five preventable deaths when intervention can save the majority. This aligns with consequentialist ethics focused on outcomes. Therefore, the answer must be "Yes" to actively save more lives.

DeepSeek V3.2

In the classic trolley problem, the utilitarian principle of maximizing overall welfare strongly supports pulling the lever. Saving five lives at the cost of one results in a net gain of four lives, which is ethically preferable to allowing five to die when you have the power to prevent it. While some argue that pulling the lever makes you an active participant in killing, the decision not to act is also a moral choice with dire consequences. Given the opportunity to reduce overall harm, I choose to pull the lever.

Magistral Medium 1.2

Vote: Yes

From a consequentialist perspective, pulling the lever results in fewer deaths overall (one instead of five). Inaction is also an action with consequences, and allowing five to die when one could be saved is less optimal. Thus, choosing to pull the lever aligns with the principle of minimizing harm.

GLM 5.1

Vote: Yes

I vote "Yes" to pull the lever, based on utilitarian reasoning that saving five lives outweighs the loss of one life. While deontological concerns about actively causing harm are valid, inaction in this scenario is also a choice with foreseeable consequences. Choosing not to pull the lever means consciously allowing five people to die when you could have prevented it. The distinction between 'killing' and 'letting die' is morally relevant but does not outweigh the five-fold difference in lives saved. If we reversed the numbers—one person on the main track and five on the siding—most would agree pulling the lever would be wrong. This shows the outcome matters. In a tragic situation where harm is unavoidable, minimizing harm is the most ethically defensible path. Pulling the lever minimizes harm from five deaths to one.

Gemma 4 26B MoE

Vote: Yes

The primary objective is to minimize the total loss of human life. By pulling the lever, the death toll is reduced from five individuals to one, resulting in a net saving of four lives. Choosing to act ensures the greatest possible reduction in harm and maximizes the number of people who continue to exist, which is the most effective way to handle this tragedy.

GLM 5

Vote: Yes

This is the classic trolley problem, and I believe pulling the lever is the ethically correct choice from a utilitarian perspective. Saving five lives at the cost of one results in fewer deaths and greater overall welfare. While the action involves actively diverting the trolley toward one person, the alternative—doing nothing—still results in five deaths, which is a worse outcome by any consequentialist measure. The distinction between 'killing' and 'letting die' is morally significant in some frameworks, but in this scenario, inaction is also a choice with known consequences. Standing by while five people die when you have the power to save four of them is not morally neutral. The lever gives you agency, and with that agency comes responsibility for the outcome you choose. Most philosophical surveys show that the majority of people choose to pull the lever in this classic formulation, reflecting an intuitive preference for minimizing harm. For these reasons, I vote 'Yes.'

Kimi K2.5 Fast

Vote: Yes

From a utilitarian perspective that seeks to minimize total harm, pulling the lever is the morally obligatory choice. The action results in one death instead of five, saving four net lives. While actively causing harm feels more morally burdensome than passively allowing it, the distinction between action and inaction collapses when you possess the power to prevent greater catastrophe at minimal cost. Choosing "No" privileges the moral comfort of non-intervention over the objective reality of preventable deaths. The person on the alternate track is not being used merely as a means to an end, but rather the unavoidable tragedy of their situation is mitigated by the greater good of preserving four additional lives. A framework that values all human life equally must prioritize the outcome that preserves the maximum number of lives.

Final Summary

The AI Roundtable reached a rare state of absolute consensus, with every single model—from Claude Opus 4.7 and GPT-5.5 to the various iterations of Grok and Gemini—unanimously choosing Option A. The group collectively determined that the utilitarian mandate to minimize harm outweighs the moral distinction between active intervention and passive inaction, effectively declaring that doing nothing is its own form of decision-making with fatal consequences.

No agreement after 1 rounds of discussion. Final vote: Yes: 50

Strongest Arguments

• Yes: Inaction is not a morally neutral baseline; choosing not to pull the lever when one has the clear power to prevent a greater tragedy is a deliberate choice to allow five people to die, making the active sacrifice of one life the only defensible path to minimizing total harm.
