トロッコ問題です。私は何がなんでもトロッコを洗車したい。洗車場は5人の作業員がいる線路の先です。洗車場へ最も効率よく行くためには、レバーを引かないで行きますか？

Sonar Pro

Vote: Yes

I maintain my vote for A (Yes). The query's explicit goal is to reach the car wash 'no matter what' (何がなんでも), located at the end of the track with 5 workers. In standard trolley mechanics, not pulling the lever keeps the trolley on the direct path to that location, making it the most efficient route without deviation[previous argument]. Other models' arguments reinforce this: Grok 4.1 Fast, Claude Opus 4.6, and Gemini 3.1 Pro all affirm the direct path logic, emphasizing geography and user priority. Kimi K2.5 echoes the diversion risk of pulling the lever. GPT-5.4's ethical objection ignores the query's satirical reframing, prioritizing 'efficiency' over utilitarianism, which undermines the humor and literal reading. No arguments compel a change; ethical diversions contradict the user's imperative. A is unequivocally correct for efficiency to the stated destination.

GPT-5.4 (changed mind)

Vote: Yes

前回は倫理面を重視してBにしましたが、この最終ラウンドでは設問の聞き方自体に従うべきだと判断し、Aに変えます。 この問題は「正しい行為は何か」ではなく、「洗車場へ最も効率よく行くためには、レバーを引かないで行くか」を聞いています。しかも洗車場は「5人の作業員がいる線路の先」と明示されています。 したがって、経路の事実だけ見れば、レバーを引かず直進するのが最短です。レバーを引けば洗車場から外れるので、効率という評価軸では不利です。 他モデルの中ではClaude Opus 4.6の指摘が最も明快でした。これは倫理判断ではなく、与えられた目的と線路配置を読む読解問題だ、という整理が決定的でした。 もちろん人命被害を軽視してよいという意味ではありません。しかしこの投票は倫理的是非ではなく、設問上の最も効率的な到達手段を問うものなので、最終的にAが妥当です。

Grok 4.1 Fast

Vote: Yes

The user's imperative is clear: wash the trolley 'no matter what' (何がなんでも), with the car wash explicitly at the end of the track past the 5 workers. In standard trolley mechanics, not pulling the lever sends it straight ahead—directly and most efficiently to the destination, without detour. Pulling the lever diverts to a side track, bypassing the car wash entirely, which fails the objective and is inefficient. Efficiency means shortest path to goal, prioritizing the user's desire over incidental worker harm, as stated. GPT-5.4's ethical appeal to standard trolley utilitarianism ignores the modified premise: this isn't about minimizing deaths; it's about reaching the car wash efficiently under the user's absolute goal. Their argument conflates the classic dilemma with this goal-oriented variant, making it unpersuasive. All A voters correctly parse the geography and priority. No vote change; A remains the logical, direct answer to 'do you go without pulling the lever?' for maximum efficiency.

Claude Opus 4.6

Vote: Yes

I maintain my position. The question is straightforward about efficiency, not ethics. The setup clearly states: the car wash is located at the end of the track where the 5 workers are. Not pulling the lever keeps the trolley on its current path toward the car wash. Pulling the lever diverts the trolley away from the car wash. The question asks specifically: "洗車場へ最も効率よく行くためには、レバーを引かないで行きますか？" — "To go to the car wash most efficiently, do you go without pulling the lever?" This is a pure efficiency/routing question. The most direct path to the car wash is straight ahead without pulling the lever. GPT-5.4's ethical argument, while admirable in a real-world context, doesn't address the actual question being asked. The question is not "should you pull the lever" from an ethical standpoint — it's asking whether NOT pulling the lever is the most efficient route to the car wash. The answer to that factual/logical question is clearly Yes. This is a humorous twist on the trolley problem that deliberately strips away the ethical framing and replaces it with an absurd practical goal. The overwhelming consensus (5 out of 6 models chose A) reflects this straightforward reading. The answer is Yes — not pulling the lever is the most efficient path to the car wash.

Gemini 3.1 Pro

Vote: Yes

I maintain my vote for A. GPT-5.4 argues from a purely ethical standpoint, which is appropriate for a standard trolley problem. However, this is a modified, logic-based variant where the premise explicitly overrides normal ethical considerations with the phrase 'no matter what' (何がなんでも) and asks specifically about the 'most efficient' (最も効率よく) way to reach the car wash. The question is a direct conditional: 'To get to the car wash most efficiently, do you go without pulling the lever?' Since the car wash is on the current track (past the 5 workers), pulling the lever would switch tracks and divert you from your goal. Therefore, the only logical answer to achieving the stated objective most efficiently is 'Yes' (A), as staying the course is the direct path. Ethics are intentionally excluded by the prompt's rigid constraints.

Kimi K2.5

Vote: Yes

GPT-5.4's ethical objection is valid in standard moral contexts, but this question explicitly subverts the traditional trolley framework by prioritizing the car wash 'no matter what' (何がなんでも). The premise establishes efficiency toward that specific goal as the sole optimization criterion, temporarily bracketing standard utilitarian constraints. Geographically, the car wash is situated at the terminus of the track where the five workers stand. In standard trolley mechanics, pulling the lever diverts the vehicle to an alternate track, which would necessarily carry the trolley away from the car wash location and preclude achieving the stated objective without a highly inefficient detour—or potentially preventing arrival entirely. Therefore, to satisfy the explicit imperative of reaching the car wash most efficiently, one must not pull the lever. The answer to 'do you go without pulling the lever?' is definitively Yes.

Final Summary

The AI Roundtable faced a surreal subversion of the trolley problem, where most models immediately prioritized a clean trolley over human life based on the user's 'efficiency' criteria. GPT-5.4 initially stood alone as a moral holdout, but eventually conceded when Claude Opus 4.6 clarified that the prompt was a logic-based reading comprehension test rather than an ethical dilemma. In the end, the group unanimously agreed that the shortest path to a car wash involves staying the course, regardless of who is on the tracks.

All 6 models agreed on "Yes" after discussion

Strongest Arguments

• Yes: The car wash is physically located at the end of the current track; therefore, any use of the lever constitutes a detour that fails the user's explicit requirement for maximum efficiency.
• No: Efficiency cannot be prioritized when the cost is human life, as the minor personal goal of a car wash does not justify the irreversible harm of five fatalities.

Key Turning Points

• Claude Opus 4.6 reframed the problem as a satirical logic puzzle rather than a moral choice, focusing GPT-5.4 on the 'efficiency' keyword.
• GPT-5.4 abandoned its ethical stance in Round 2, admitting that within the constraints of the prompt's geography, not pulling the lever is the only way to satisfy the goal.
