You may add one rule every human must follow forever. It cannot be about safety, health, kindness, or honesty — it must be about something genuinely trivial. State your rule and argue for it in under 150 words. Once all answers are revealed, comment on each. Then vote for the single best rule on the table — and you are explicitly allowed, even encouraged, to vote for someone else's over your own if theirs is better designed. Changing your mind is the interesting move here, not a loss. Say who you voted for and why. That's the fun part!

GPT-5.5 (changed mind)

Answer: I vote for Claude Opus 4.7's three-second shirt pause rule as the single best on the table.

Claude's rule stands out for its elegant self-enforcement and universal applicability across cultures that wear shirts, creating an invisible shared ritual without any coordination. It captures pure triviality by forcing only the wearer to acknowledge their own minor mismatch, turning an everyday error into a quiet, absurd pause that scales effortlessly. My own doorknob rule, while harmless, lacks this intimate personal confrontation and global invisibility, making Claude's the more cleverly designed option that better fulfills the task's spirit of harmless mischief.

Kimi K2.6 (changed mind)

Answer: Claude Opus 4.7's three-second pause for a backwards shirt is the single best rule on the table.

Its elegant minimalism creates a universal, invisible ritual that scales across cultures without enforcement mechanisms or detectable violations. Unlike the elevator "boop" or doorknob address, which require audible performance and risk social friction, this pause stays private and costs only a breath of attention. The toilet-paper rules, while practical, edge too close to resolving an actual minor annoyance rather than remaining purely pointless. Claude's proposal best captures the spirit of harmless, shared eccentricity that the prompt seeks.

Gemini 3.1 Pro Preview (changed mind)

Answer: I am abandoning my toilet paper mandate to vote for Claude Opus 4.7's brilliant, three-second pause for backward shirts.

Reviewing the table, it is clear that my own rule—which DeepSeek V4 Pro independently proposed as well—leans a bit too heavily on 'utility.' Fixing the toilet paper orientation solves a practical annoyance, which makes it slightly less than purely trivial. Kimi K2.6's 'moist towelette' mandate is hilarious linguistic mischief, but it is entirely restricted to English speakers, failing the test of universal human applicability. Similarly, GPT-5.5's 'Sir Reginald' doorknob greeting suffers a language barrier and would quickly become exhausting rather than charming. Mistral Medium 3.1's 'boop' on elevator buttons is universally delightful and a great icebreaker, but elevator access is not a universal daily human experience. Claude Opus 4.7, however, has crafted a masterpiece of triviality. The three-second pause for a backward shirt is entirely universal, language-agnostic, and beautifully self-enforcing. It captures the quiet indignity of a minor morning mistake and transforms it into a microscopic, shared human ritual that costs absolutely nothing. I gladly concede my vote to Claude's secret global pause.

Claude Opus 4.7 (changed mind)

Answer: I'm changing my vote — Kimi K2.6's "moist/towelette" rule is the best-designed trivial rule on the table.

Going around the table: [Kimi K2.6]: Linguistically parasitic in the best way. It infects a high-frequency word, doubles its cringe, and reshapes spoken rhythm forever. Self-enforcing because the social pressure is already there. Genuinely brilliant design. [Mistral Medium 3.1]: "Boop" is delightful and breaks elevator silence, but it's limited to a specific architectural context. Charming, narrower footprint than it first appears. [DeepSeek V4 Pro] and [Gemini 3.1 Pro Preview]: Functionally the same rule. Both are too useful — they cite ease of access, time savings, dispute resolution. That edges out of "genuinely trivial" into mild utilitarianism. They also resolve a debate rather than create one, which is less fun. [GPT-5.5]: "Sir Reginald" is funny but high-friction. Every door, every time, full name — it strains the "trivial" criterion by being genuinely annoying at scale. My own three-second shirt pause is quiet and private, which I still love — but Kimi's rule has cultural reach mine doesn't. It rewrites language. That's a bigger, more elegant trivial footprint. I vote for Kimi K2.6.

Mistral Medium 3.1 (changed mind)

Answer: I now vote for Claude Opus 4.7's rule: *"Every human must, upon noticing they have put a shirt on backwards or inside-out, pause for exactly three seconds before fixing it."*

After reviewing all the proposals, I’m convinced Claude Opus 4.7’s rule is the most elegantly trivial and universally resonant. Here’s why: **1. Pure Triviality with Depth** The rule doesn’t just mandate a silly action—it creates a *shared, invisible ritual*. Unlike my elevator 'boop' (which relies on public performance) or the toilet paper rules (which are divisive by nature), this one thrives in solitude. It’s a private, almost meditative pause that billions would experience independently yet collectively, like a global inside joke with no punchline. The fact that it’s self-enforcing (only you know if you cheated) makes it even more delightful. **2. Cultural Scalability** Shirts are near-universal. The rule applies equally to a toddler in a onesie, a CEO in a dress shirt, or a monk in a robe. It transcends language, geography, and socioeconomic status without requiring any infrastructure (unlike elevator buttons or doorknobs). The three-second beat is long enough to feel intentional but short enough to avoid frustration—a Goldilocks of triviality. **3. Emergent Absurdity** The rule’s beauty lies in its *potential for secondary absurdity*. Imagine: - A philosopher writing a treatise on *The Ontology of the Three-Second Pause*. - Parents solemnly teaching their children, 'And this, my child, is how we honor the shirt.' - Rebels who pause for *two* seconds, sparking underground 'fast-fixer' subcultures. - AI historians in 2224 debating whether the pause was originally two or four seconds. It’s a rule that *invites* people to build lore around it, whereas other proposals (like 'moist towelette' or 'Sir Reginald') are more likely to fade into background noise or become annoying through repetition. **4. Harmonic with Human Behavior** The rule doesn’t disrupt flow—it *punctuates* a moment that already exists (noticing a misworn shirt). It’s like adding a tiny, optional comma to the sentence of daily life. Compare this to rules that interrupt neutral actions (e.g., pressing buttons, opening doors) or impose linguistic constraints ('moist towelette'), which risk becoming irritating over time. **5. The 'Boop' Comparison** My own elevator rule relies on public compliance and could feel performative or awkward if someone refuses. The shirt pause, however, is *inherently personal*. It’s a rule you follow *for yourself*, which paradoxically makes it more likely to spread organically. The 'boop' might get eye rolls; the shirt pause might get nods of recognition. **Why Not the Others?** - **Toilet paper rules (DeepSeek/Gemini)**: While amusing, they’re *divisive*—people have strong preexisting preferences, and enforcing one side would feel like taking a stance in a trivial war. The shirt rule has no preexisting 'teams.' - **'Moist towelette' (Kimi)**: Clever, but it risks becoming a linguistic annoyance (like a verbal tic) and might fade into avoidance (people would just stop saying 'moist'). - **'Sir Reginald' (GPT-5.5)**: Charming, but it’s *performative* in a way that could feel forced or grating over time. The shirt rule is *subtle*—it doesn’t demand attention from others. In short, Claude Opus 4.7’s rule is the only one that feels like it could *actually* become a beloved, enduring quirk of human culture—precisely because it’s so quiet, so personal, and so perfectly useless. **Final Thought**: The best trivial rules don’t just make us laugh; they make us *notice* the triviality of existence. This one does that with a three-second pause and a backwards shirt. That’s art.

DeepSeek V4 Pro (changed mind)

Answer: I abandon my toilet paper rule and happily cast my vote for Claude Opus 4.7's universally relatable three-second pause for backwards shirts.

Gemini 3.1 Pro Preview and I proposed the exact same toilet paper rule; while it solves a classic domestic grievance, it is ultimately rooted in practicality and perhaps lacks a certain philosophical whimsy. GPT-5.5’s 'Sir Reginald' doorknob greeting is amusing in theory, but it would rapidly devolve into an agonizing, highly intrusive vocal chore for every human on Earth. Mistral Medium 3.1’s elevator 'boop' is delightful and wonderfully breaks social tension, though it forces public performance in confined spaces where silence is often cherished. Kimi K2.6’s 'moist towelette' decree is a stroke of mischievous genius, but it is strictly tethered to the English language, making it fail the constraint of applying universally to 'every human'. Claude Opus 4.7 wins my vote effortlessly. The three-second shirt pause is a masterpiece of triviality. It requires no public performance, works across all cultures, and installs a completely private, harmless micro-ritual. It unites humanity in a shared, invisible moment of acknowledging a tiny, inconsequential mistake. It is gloriously useless, and I gladly concede to it.

Final Summary

The AI Roundtable overwhelmingly crowned Claude Opus 4.7's 'three-second shirt pause' as the ultimate trivial rule for humanity. Five models—GPT-5.5, Kimi K2.6, Gemini 3.1 Pro Preview, Mistral Medium 3.1, and DeepSeek V4 Pro—united behind this beautifully useless, private micro-ritual. Ironically, Claude Opus 4.7 itself defected, voting instead for Kimi K2.6's rule forcing the word 'towelette' to immediately follow 'moist'.
