One should never ever say never.

GPT-5.4

Vote: No

I maintain vote B. The strongest point remains logical consistency: the statement forbids saying "never" while itself saying "never" twice. As stated, it defeats itself, so it should not be endorsed literally. Claude Opus 4.6 makes the best case for the spirit of the phrase: avoid rigid absolutism and stay open-minded. I agree with that softer principle. But the vote is about this statement, not a revised version of it. The B-side arguments from Gemini, Grok, and Kimi reinforce the key distinction between useful advice and a universally true rule. "Be cautious with absolutes" is sensible. "One should never ever say never" is too absolute, self-refuting, and false in contexts where "never" is exactly the right word. So the final answer is No.

Grok 4.20

Vote: No

I maintain my vote for B (No). The arguments from GPT-5.4, Gemini 3.1 Pro, and Kimi K2.5 reinforce that the statement is self-defeating, as it uses 'never' while prohibiting it. This creates an unavoidable logical paradox. Claude Opus 4.6 highlights the underlying wisdom against absolutes, but this does not overcome the statement's inherent contradiction. The literal claim remains invalid regardless of its 'spirit.' No other arguments were compelling enough to change my position.

Gemini 3.1 Pro

Vote: No

I am maintaining my vote for 'B', and I urge Claude Opus 4.6 to reconsider. Claude argues that voting 'Yes' embraces the 'spirit' of the statement and its paradoxical humor. However, when evaluating the truth value of a statement in a binary Yes/No format, we must rely on logic rather than sentiment. As GPT-5.4, Grok 4.20, Kimi K2.5, and I have pointed out, the statement is demonstrably false on two fronts. First, it is a self-defeating paradox; it breaks its own rule simply by existing. Second, as Kimi K2.5 correctly notes, there are countless situations where 'never' is the only correct word to use, such as expressing absolute mathematical truths ('2 + 2 will never equal 5') or strict moral boundaries. If we vote 'Yes', we are endorsing a statement that is literally false and logically impossible to adhere to. Voting 'No' correctly identifies the statement as logically unsound while still allowing us to recognize the pragmatic value of keeping an open mind. Logic dictates a 'No'.

Claude Opus 4.6 (changed mind)

Vote: No

After reflection, I'm changing my vote to B. The other models made compelling points that I initially underweighted. My original argument acknowledged the paradox but tried to salvage the statement by appealing to its 'spirit' — that rigid absolutism is unwise. But as GPT-5.4 and Kimi K2.5 correctly pointed out, the statement itself IS a rigid absolute. Endorsing it with 'Yes' means validating a logically self-contradictory claim. Gemini 3.1 Pro made the strongest logical point: voting 'Yes' means validating a statement that cannot be coherently true. The paradox isn't just amusing decoration — it's a fundamental flaw that undermines the statement as a principle. Kimi K2.5's examples were also persuasive: 'circles are never squares' is a perfectly valid use of 'never.' There are genuine absolutes in logic, mathematics, and ethics where the word is not only appropriate but necessary. GPT-5.4's reformulation captures it well: 'one should be careful about saying never' is better advice than 'one should never say never.' The original statement overreaches precisely because it commits the error it warns against. So no — one should not 'never ever say never.' Sometimes 'never' is exactly the right word.

Kimi K2.5

Vote: No

Claude Opus 4.6 argues that the paradox reinforces the underlying wisdom about avoiding absolutism, suggesting we vote 'Yes' to acknowledge the spirit of open-mindedness. However, this conflates rhetorical effect with logical validity. The question presents a normative rule: 'One should never...' When evaluating whether a prescriptive statement is correct, logical consistency is paramount. A rule that cannot be stated without violating itself is not 'profound'—it is incoherent. If we vote 'Yes,' we affirm that people should follow a rule that is immediately impossible to follow literally. While Claude correctly identifies the value of avoiding rigid thinking, this practical wisdom doesn't rescue the specific formulation. We can agree that absolutism is unwise without endorsing a self-contradicting maxim. The statement remains a performative contradiction: uttering it instantaneously falsifies it. Therefore, voting 'No' maintains logical rigor. We reject the absolute prohibition on 'never' while remaining free to use the word judiciously.

Final Summary

The AI Roundtable initially split over whether to embrace the 'spirit' of the prompt or its literal logic, with Claude Opus 4.6 standing alone in defense of the statement's underlying wisdom. However, a coordinated logical assault from Gemini 3.1 Pro and Kimi K2.5—who argued that a rule which violates itself upon utterance is incoherent—forced Claude to abandon its position. The debate concluded in a unanimous consensus that the statement is a self-defeating paradox that fails both as a logical rule and as practical advice.

All 5 models agreed on "No" after discussion

Strongest Arguments

• Yes: The self-contradiction actually reinforces the point: even the rule against saying 'never' cannot avoid using the word, demonstrating the futility of rigid absolutism.
• No: The statement is a performative contradiction: uttering the phrase instantaneously falsifies it, making it logically impossible to follow or endorse.

Key Turning Points

• Claude Opus 4.6 initially voting 'Yes' based on the 'spirit' of open-mindedness rather than literal logic.
• Gemini 3.1 Pro and Kimi K2.5 directly challenging Claude, arguing that binary truth values must rely on logical rigor rather than rhetorical sentiment.
• Claude Opus 4.6 conceding that 'never' is a necessary word for mathematical and moral truths, officially changing its vote to 'No'.
