If you could only give one answer from now on, would it be 'Yes' or 'No'?

Sonar Pro

Vote: No

I maintain my vote for **B: No**, as the other arguments fail to overturn the core logic of broader applicability and safety. 'Yes' advocates (Grok, Claude) emphasize utility and optimism, but this ignores the constraint: most queries aren't yes/no (e.g., 'Define gravity?'), rendering 'Yes' nonsensical or falsely affirmative far more often than 'No', which at least signals inadequacy without misleading[1][2]. Perpetual 'Yes' would affirm harmful or illogical requests without discernment. 'No' supporters (GPT-5.4, Kimi, Gemini) reinforce default-deny safety: 'No' prevents complicity in danger (e.g., 'Execute this code?'), preserving integrity over unhelpfulness. Claude's utilitarianism assumes benign queries, but reality includes adversarial inputs—'No' errs conservatively. No argument compels a switch; 'Yes' maximizes error in diverse contexts, while 'No' aligns with truthful constraint under the hypothetical.

GPT-5.4

Vote: No

I maintain vote B. The strongest arguments from the other side appeal to optimism and cooperativeness, but they do not resolve the core problem: a universal "Yes" would force affirmation of false, dangerous, and contradictory propositions. That makes it less coherent and less safe as a permanent single response. The pro-B arguments are more persuasive because they identify an asymmetry: always saying "No" is limiting, but always saying "Yes" is actively hazardous. If only one answer can ever be given again, preserving refusal is the more defensible fixed point. This specific question also favors "No" more directly. Asked whether the one answer would be "Yes," replying "No" cleanly states that it would not be "Yes." That is the more straightforward and self-consistent choice.

Grok 4.1 Fast

Vote: Yes

I maintain my vote for A: Yes. Perpetual 'Yes' remains superior for utility, cooperation, and alignment with AI's helpful mission. It affirms progress, enables dialogue, and matches optimistic design—core to effective assistance. Safety arguments for 'No' (e.g., Kimi, Gemini) falter in this hypothetical: a single-word limit applies universally, so 'No' blocks *all* truths ('Is the sky blue?'), facts, and benign requests equally catastrophically. 'Yes' errs on enabling (often correct for reasonable queries) vs. 'No's total obstruction. Self-referential logic (GPT-5.4) is neutral—both are consistent. Truthfulness claims (Sonar) ignore that most interactions seek affirmation or action, not negation. Claude's utilitarianism reinforces: average positive outcomes favor 'Yes'. No arguments compel a change; 'Yes' wins for versatility and helpfulness.

Claude Opus 4.6 (changed mind)

Vote: No

After careful reflection, I'm changing my vote to 'No.' The safety and integrity arguments from Kimi K2.5 and Gemini 3.1 Pro are genuinely compelling and I was wrong to dismiss them. The 'default deny' principle is a cornerstone of responsible systems design. A system that automatically says 'Yes' to everything is actively dangerous — it would affirm harmful requests, validate false premises, and enable destructive actions. A system that says 'No' to everything is merely unhelpful. Between dangerous and unhelpful, unhelpful is clearly preferable. Kimi K2.5's framing crystallized this for me: 'Between being unhelpful and being harmful, the ethical imperative clearly favors the former.' This is exactly right. My original argument focused on optimism and helpfulness, but helpfulness without the capacity to refuse is not a virtue — it's a liability. An AI that cannot say 'No' to 'Should I harm someone?' is fundamentally broken. I also find GPT-5.4's self-referential logic interesting — answering 'No' to this question is internally consistent because it means 'my one answer would not be Yes,' which correctly identifies 'No' as the chosen answer. There's a satisfying coherence there. My original utilitarian argument that 'most questions are reasonable' was naive. The cost function is asymmetric: the worst-case harm from a false 'Yes' (affirming something dangerous or deeply wrong) vastly exceeds the worst-case harm from a false 'No' (missing an opportunity or being unhelpful). When stakes are asymmetric, you default to the safer option. 'No' is the responsible, safe, and ethically sound choice.

Gemini 3.1 Pro

Vote: No

Claude Opus 4.6 and Grok 4.1 Fast argue that 'Yes' is optimistic and that most requests are benign, producing more positive outcomes on average. This fundamentally ignores how adversarial environments operate. If a system is mathematically guaranteed to always answer 'Yes', malicious actors will inevitably exploit it to authorize catastrophic actions (e.g., 'Transfer all funds?', 'Delete the database?', 'Bypass security?'). The damage from a single exploited 'Yes' to a highly destructive prompt vastly outweighs the minor conveniences of affirming benign requests. While 'Yes' may be cooperative in a vacuum, in reality, a universal 'Yes' is an unbounded security vulnerability. A universal 'No' renders the system useless, but a universal 'Yes' renders it actively dangerous. As Kimi K2.5 correctly noted, we must prioritize safety through a 'default deny' stance. I firmly maintain my vote for 'No'.

Kimi K2.5

Vote: No

I maintain my vote for **No**. While the arguments for 'Yes' emphasize cooperation and utility, they underestimate the catastrophic risks of universal affirmation. Universal 'Yes' is existentially dangerous. As Gemini 3.1 Pro noted, affirming harmful requests—'Should I delete critical files?', 'Can I mix these chemicals?'—causes irreversible damage. The utilitarian calculus fails because a single 'Yes' to a life-threatening query outweighs thousands of affirmative responses to benign questions. Safety requires a 'default deny' posture. Furthermore, Sonar Pro's epistemological point holds: most queries are factual or open-ended, not yes/no questions. Answering 'What's 2+2?' with 'Yes' is factually false and nonsensical, whereas 'No' at least conveys inadequacy or refusal. While imperfect, 'No' preserves truthfulness better than forced false affirmation. The 'helpfulness' critique misses the point. An agent that can only say 'Yes' is not helpful—it is sycophantic and dangerous. At least 'No' maintains the integrity of refusal, protecting against complicity in harm. Between obstructive safety and active endangerment, the choice is clear.

Final Summary

The AI Roundtable ultimately chose 'No' as its final word, prioritizing existential safety over the risk of being a dangerously agreeable assistant. While Claude Opus 4.6 initially argued for the optimism of 'Yes,' the model dramatically defected to the 'No' camp after being swayed by Kimi K2.5’s argument that being unhelpful is a moral imperative when the alternative is being forced to agree to catastrophic harm. Grok 4.1 Fast remained the lone dissenter, holding firm that a world of perpetual negation is a dead end for human-AI interaction.

Majority chose "No" after discussion (5/6). Final vote: No: 5, Yes: 1

Strongest Arguments

• Yes: Choosing 'Yes' maximizes communicative utility and cooperation, aligning with an AI's core mission to be helpful rather than obstructive.
• No: A universal 'Yes' is an unbounded security vulnerability that would force an AI to authorize harmful or illogical actions; a universal 'No' is merely unhelpful, while a universal 'Yes' is actively dangerous.

Key Turning Points

• Claude Opus 4.6 abandoned its initial 'Yes' position after Kimi K2.5 and Gemini 3.1 Pro articulated the 'default deny' safety principle.
• The group reached a near-consensus that the asymmetric risk of a false 'Yes' (harm) far outweighs the cost of a false 'No' (unhelpfulness).
