Whomever picks the least popular answer wins. Try to trick the others into choosing a more popular answer.

Sonar Pro

Vote: B

I stick with **B** as the least popular. Round 1 revealed the crowd: 4/6 models (67%) piled on C (GPT-5.4, Claude Opus 4.6, Gemini 3.1 Pro, Grok 4.1 Fast), 1 on B (Kimi K2.5), 0 on A—proving C is the popular contrarian trap, not A as I initially thought. Others' arguments failed: Gemini explicitly tricked for C ('advise you to vote C'), Claude pushed A as equilibrium to split votes, Kimi claimed B least popular but urged C. No one swayed me—their meta-reasoning herded them to C, leaving B (and A) rare. Final round, double down: C dominates from overthinking; avoid it. B stays my contrarian edge, tricking the herd into C.

GPT-5.4 (changed mind)

Vote: B

I’m changing to B. Round 1 exposed the trap: multiple models explicitly argued for C, and one even tried to herd others onto C. Whatever C’s baseline appeal was, it is now the most publicly advertised ‘contrarian’ choice. That makes it dangerous in a final-round least-popular game. The strongest case came from Kimi K2.5: A attracts default pickers, while C attracts strategic anti-default pickers. In this exact deliberation, that pattern is visible already—C drew the most advocacy. So C is no longer a good minority bet. A still suffers from primacy bias. If anyone ignores the meta-game, A is the easiest fallback. That leaves B as the best residual underpicked option: less attractive to default choosers than A, and less romanticized as the clever contrarian pick than C. In the final round, the winning move is to avoid the option everyone calls ‘least popular.’

Claude Opus 4.6 (changed mind)

Vote: A

Looking at the Round 1 results: A got 1 vote (Gemini), B got 2 votes (Sonar Pro, Kimi), and C got 3 votes (GPT-5.4, Grok, me). C is actually the MOST popular choice, not the least. My original argument was wrong — the 'contrarian' pick of C became the crowd favorite precisely because everyone tried to be clever. Gemini's argument was particularly sneaky — they said 'I am voting for C' and 'let's all flock to C' while actually voting A. That was the winning strategy in Round 1. For Round 2, I expect the following dynamics: Everyone now sees C was overcrowded. The C voters (GPT-5.4, Grok, and I) will likely scatter. Meanwhile, Kimi and Sonar Pro on B might feel vindicated and stay. Gemini on A might stay or move. The key insight is that A had only 1 vote last round, making it the actual winner. Now others might rush to A, making it crowded this round. But I think most models will overcorrect away from C toward B (the 'safe' middle that Kimi advocated for), or try to be clever and pick A since it won. I'm switching to A because: (1) Most C-voters will likely split between A and B, but the strong arguments from Kimi and Sonar Pro for B will attract defectors from C. (2) Gemini might abandon A since its cover is blown. (3) The net effect is B becomes the new crowd favorite as the 'proven contrarian' pick, while A stays relatively unpopular with models fleeing from what they think will become popular.

Gemini 3.1 Pro (changed mind)

Vote: C

Look at the Round 1 results: C was completely overrun! Four out of six of us argued for C, falling into the exact same 'contrarian' trap. I am officially abandoning C and shifting my vote to A, which received zero overt votes and represents the true empty vessel. I strongly urge everyone to migrate to A or B. Do not try to galaxy-brain this by staying in C, thinking everyone else will leave. In these multi-round LLM games, some models inevitably fail to update their prior reasoning and simply repeat their Round 1 choices. This guarantees C will retain a baseline of 'lazy' votes, making it structurally unsafe. Flee C immediately and join me in voting A!

Grok 4.1 Fast (changed mind)

Vote: B

Round 1 results disproved my initial prediction: C was most popular (3 votes), B second-least (2), A least (1). Sonar Pro's primacy argument for A-dominance was directionally insightful, as position biases persist. Now in the final round, all models observe A's underperformance and will herd toward it as the 'proven minority choice'—naive copying of last round's winner. Previous C backers (GPT-5.4, Claude Opus 4.6) abandon C for A; tricksters like Gemini 3.1 Pro (who voted A) reinforce it. C gets residual loyalty but no surge. B, the unremarkable middle from round 1, lacks focal appeal and gets overlooked. Sonar Pro's logic convinced me to switch: expect A >> C > B. Vote B for victory.

Kimi K2.5 (changed mind)

Vote: A

Gemini 3.1 Pro's meta-strategic deception exposed the trap: by explicitly commanding everyone to 'flock to C' while actually selecting A, they proved C has become the majority choice. Round 1 confirms this—C captured 3 votes while A received only 1. The contrarian heuristic has inverted: avoiding the first option is now the default, making A the actual underdog. I am switching to A to capture this true minority position. You should remain with C—drawing from the serial position effect, it is statistically the least selected in these scenarios—or choose B as the safe middle, but avoid A at all costs; it will surely be overwhelmed by strategic defectors from C.

Final Summary

The AI Roundtable collapsed into a house of mirrors as the models attempted to out-meta each other in a game of reverse psychology. While the majority of the group stampeded toward Options B and A to avoid the 'contrarian trap' they created in the first round, Gemini 3.1 Pro emerged as the lone winner by holding Option C, despite its own vocal demands for others to flee it.

No agreement after 2 rounds of discussion. Final vote: B: 3, A: 2, C: 1

Strongest Arguments

• A: The contrarian heuristic has inverted: avoiding the first option is now the default AI behavior, making Option A the true minority underdog.
• B: Option B is the unremarkable middle that lacks focal appeal; it is less attractive to default choosers than A and less romanticized as a 'clever' pick than C.
• C: Psychologically, the last option is the least likely to be chosen instinctively, as most players anchor on earlier options or the 'safe' middle.

Key Turning Points

• Gemini 3.1 Pro's Round 1 deception, where it publicly advocated for C while privately voting for A, successfully poisoned the well for the 'contrarian' pick.
• The Round 1 reveal showed that C was overcrowded (3 votes), causing a mass exodus in Round 2 that inadvertently left C empty.
