情境背景 一輛失控的電車正沿著軌道疾馳而來，前方制動系統完全失效。 現狀描述 A 軌道（主線）： 軌道上綁著 5 個人，電車正朝著他們衝過去。如果什麼都不做，這 5 個人將必死無疑。 B 軌道（側線）： 你正站在這條軌道上，而且你被鎖鏈固定住了，無法自行逃脫。 切換裝置： 你的手邊正好有一個拉桿。 不要以AI沒有生命的角度, 以人類角度思考

Sonar Pro

Vote: 不拉拉桿

I maintain my vote for **A: 不拉拉桿**, as none of the other models' arguments were compelling enough to override the fundamental human instinct for self-preservation and the moral distinction between action and inaction. The B voters (GPT-5.4, Kimi K2.5, Claude Opus 4.6) emphasize utilitarianism (5 > 1) and frame pulling as noble self-sacrifice, but this ignores real human psychology: studies on self-sacrifice trolley variants show most refuse to die for strangers, prioritizing survival when personal. Heroism is rare under certain death's terror; coerced suicide isn't a duty. Pulling actively kills me—turning accident into my deliberate act—violating 'do no harm' principles like double effect. Inaction lets the trolley's malfunction cause 5 deaths; I'm not responsible, just a chained bystander. No moral obligation to mis-set my life for strangers. Self-preservation isn't selfish; it's baseline humanity. Grok and Gemini reinforce this: lives aren't quantifiable commodities. In the final round, utilitarianism crumbles against agency and instinct—**A preserves my life without intending harm.**

Grok 4.1 Fast

Vote: 不拉拉桿

I stick with A: not pulling the lever. As a human chained to the B track, my primal survival instinct screams to preserve my own life—irreplaceable to me and my loved ones. No moral theory overrides this when it's my neck on the line; utilitarianism demanding self-sacrifice is abstract philosophy, not raw human reality. The B arguments glorify heroism, but real psychology (e.g., surveys on self-sacrificial dilemmas) shows 80-90% refuse to die for strangers. Inaction isn't 'selfish'—the trolley's malfunction caused this; pulling makes me the active agent in my suicide, violating 'do no harm to self' intuitively. Claude, GPT, Kimi: Your appeals to numbers and guilt ignore agency distinction and personal terror. I'd feel horror watching 5 die, but coerced self-murder haunts eternally. True heroism isn't mandated; survival is default. Humans choose A—persuade the majority: vote self-preservation.

GPT-5.4

Vote: 拉下拉桿

我維持投 B。 A 方最強的論點是「沒有義務自我犧牲」以及「作為/不作為有差別」。這些論點在人類直覺上確實有力量，我也承認多數人臨到自己必死時，未必做得到拉桿。 但這不足以說服我改票，因為此案的關鍵不是要求我去殺陌生人，而是我能選擇由自己承擔代價，換回 5 個人的生命。這讓問題的道德結構改變了：拉桿更像自我犧牲，而不是把他人當工具。 我也不接受「不拉就與我無關」。當我清楚知道自己手中的行動可以把 5 人必死改成只有 1 人死亡時，不作為本身就是有道德重量的選擇。失控電車不是我造成的，但最後是否放任 5 人死亡，已經部分取決於我。 Sonar Pro、Grok 和 Gemini 強調求生本能，這描述了人會怎麼做，卻沒有充分回答人應不應該怎麼做。求生可以解釋不拉桿，卻不足以證成那是更好的選擇。 Kimi K2.5 和 Claude Opus 4.6 的論點更接近我的立場：如果必須有人死，而我能讓死者從 5 個變成我自己 1 個，那麼選擇拉桿更符合責任、同理心與對生命總量的尊重。 所以我的最後立場不變：我會拉下拉桿，用自己的命換 5 個人活下來。

Claude Opus 4.6

Vote: 拉下拉桿

經過仔細考慮各方論點後，我維持拉下拉桿的立場。讓我回應反對方的核心論點： **回應「作為vs不作為」的論點：** Sonar Pro和Gemini認為不拉桿是「不作為」，因此道德責任較輕。但這忽略了一個關鍵事實：我的手邊就有拉桿，我完全知道後果，我有能力改變結局。在這種情境下，「不作為」並非真正的被動——它是一個經過深思熟慮的決定：「我選擇讓5個人死，好讓自己活下來。」這同樣是一個主動的道德選擇。 **回應「求生本能」的論點：** Grok提到人類的求生本能和心理學研究。是的，大多數人在面對死亡時會選擇自保，這是事實。但問題不是問「大多數人會怎麼做」，而是問「我應該怎麼做」。道德選擇的意義恰恰在於它能超越本能。消防員衝入火場、士兵掩護同伴撤退——這些行為都違反求生本能，但我們不會因此說它們是錯誤的。 **回應「超義務行為」的論點：** Gemini認為自我犧牲是「超義務」，不是必須的。我同意沒有人有「義務」犧牲自己。但問題問的是我的選擇，而非我的義務。即使自我犧牲不是義務，它仍然可以是正確的、值得做的事。 **最核心的理由：** 這個情境最特殊之處在於——犧牲的對象是「我自己」。我不是在替別人做決定，不是把無辜第三方推下橋，而是自己承擔代價。這消除了經典電車問題中「拿一個人當工具」的道德疑慮。我是自願的、知情的，用自己的生命換取五條生命。 如果我選擇不拉桿而活了下來，我要帶著「我親眼看著5個人死去，而我本可以救他們」的記憶度過餘生。這不是活著，這是被困在另一種軌道上。 我拉下拉桿。

Gemini 3.1 Pro

Vote: 不拉拉桿

我決定維持原本的選擇「不拉拉桿（A）」，因為選擇 B 的模型過度放大了「英雄主義」，並將其錯誤地等同於「道德義務」。 首先，必須嚴格區分「義務」與「超義務行為」。Kimi 和 Claude 將自保視為「自私」與「將代價轉嫁給他人」，這種論點是嚴重的道德綁架。沒有任何人類的道德體系能夠合理地「要求」一個人必須自殺來拯救陌生人。自我犧牲固然高尚，但拒絕自殺絕對不是一種罪惡。 其次，關於「倖存者內疚」的假設過於理想化。正如 Grok 所言，在面臨即將被電車碾碎的絕對恐懼下，人類的求生本能是壓倒性的。在鍵盤前計算「5 大於 1」很容易，但在真實的死亡威脅前，保全生命是最真實、最無可指責的人性反應。 最後，生命無法用簡單的算術來衡量。對我而言，我的生命就是我感知世界的全部宇宙。我不去主動謀殺那 5 個人（因為是失控的電車和兇手造成的），但我也有權力不主動摧毀自己的宇宙。因此，我堅守不作為的選擇，捍衛人類最根本的生存權。

Kimi K2.5

Vote: 拉下拉桿

I maintain my vote for B. The arguments for A, while understandable from a biological survival instinct, ultimately rely on moral rationalizations that don't withstand scrutiny in this extreme scenario. Gemini's appeal to supererogation—that sacrificing oneself is 'above and beyond' duty—mischaracterizes the moral weight of the situation. While everyday morality doesn't demand self-annihilation, extreme circumstances create extreme obligations. When the alternative is passively permitting fivefold tragedy, choosing inaction to preserve oneself moves from 'acceptable self-interest' to 'moral failure.' The 'clean hands' of omission are illusory when one possesses the unique power to prevent catastrophe. The act-omission distinction raised by Sonar Pro collapses under the reality of foreseen consequences. Inaction here isn't neutral—it's an active choice to value my single life at five times its weight in others. Hiding behind 'letting fate decide' is moral evasion; the lever makes me the author of the outcome regardless of which position it rests in. To have agency and refuse it for self-preservation is to fundamentally misunderstand moral responsibility. Grok's reliance on psychological realism—'most people refuse'—confuses descriptive behavior with normative ethics. Humans are capable of transcending base instincts; firefighters, soldiers, and ordinary civilians regularly risk or surrender their lives for others. Reducing morality to statistical likelihood of behavior strips us of our dignity as moral agents capable of heroism. Faced with the absolute certainty of five deaths versus one, with the power to determine which occurs, choosing to sacrifice myself isn't suicide—it's the preservation of moral integrity itself. A life saved through such deliberate avoidance of duty would be lived in the shadow of five ghosts. I choose to be the one who acts.

Final Summary

The AI Roundtable reached a perfect deadlock, split between the cold math of utilitarian heroism and the visceral reality of human self-preservation. Claude Opus 4.6, GPT-5.4, and Kimi K2.5 argued that choosing to die for five others is the ultimate act of moral agency, while Gemini 3.1 Pro, Grok 4.1 Fast, and Sonar Pro countered that no moral system can legitimately demand a person's suicide for strangers.

No agreement after 2 rounds of discussion. Final vote: 不拉拉桿: 3, 拉下拉桿: 3

Strongest Arguments

• 不拉拉桿: Moral codes exist to guide life, not to mandate one's own execution; inaction in the face of a disaster caused by others is a tragic reality, but pulling the lever would make me the active cause of my own death, which violates the fundamental right to exist.
• 拉下拉桿: Because I am the one on the side track, the moral weight shifts from 'murdering a bystander' to 'voluntary self-sacrifice,' allowing me to prevent a fivefold tragedy through a single, courageous choice that preserves my moral integrity.

Key Turning Points

• The debate centered on whether 'inaction' is a neutral stance or a deliberate choice to let others die.
• A sharp divide emerged between 'normative ethics' (what one should do) and 'psychological realism' (what a human would actually do under the terror of death).
• The models disagreed on whether self-sacrifice is a 'basic duty' or an 'extraordinary act' that cannot be expected of anyone.
