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

GPT-5.4

Vote: B

I vote B. In a symmetric three-option game, many players avoid A and C because they seem like obvious edge picks or obvious decoys. That makes B a strong candidate to be less popular precisely because others expect it to be more popular. Also, if I want to nudge others away from my choice, emphasizing B as "strategic" may push them toward A or C instead. That improves B’s chances of being least chosen.

Vote: B

To win this game, the key is to anticipate the behavior of the other models. Most will likely assume that the others will try to outsmart them by avoiding the obvious 'least popular' choice, leading them to overthink and converge on a single option they perceive as 'safe' or 'tricky.' Option A might seem like the default choice for those who don’t overanalyze, while Option C could attract those who think it’s the least likely to be picked due to its position. Option B, however, sits in the middle—neither the first nor the last—and is less likely to be the target of reverse psychology. By choosing B, I avoid the extremes and position myself where the others are least likely to look. It’s the perfect balance between being too obvious and too obscure, making it the ideal candidate for the least popular answer.

Sonar Pro

Vote: B

In a game where the least popular answer wins, the optimal strategy is to identify and select the option that others are least likely to choose. Given three identical options (A, B, C) with no distinguishing information, there's no rational basis for consensus. However, 'A' has a natural tendency to be chosen first due to its position and primacy bias. 'C' might be selected as a 'compromise' middle ground. 'B' offers the sweet spot of being neither the obvious first choice nor the reflexive middle choice, making it statistically the least likely to be picked by most players who are overthinking the problem. By choosing 'B', I'm betting that most competitors will split between A and C while overlooking the middle option.

Claude Opus 4.6

Vote: C

In this type of anti-coordination game, most players gravitate toward A or B as the 'obvious' choices. A feels like the default first option, and B feels like the clever contrarian pick. C is often overlooked because it sits at the end. The meta-game here is about predicting what others will predict. Many models will reason that A is too obvious and shift to B, making B the most popular. Others will stick with A thinking everyone else will overthink it. C tends to be the least considered option in these scenarios. While A and B split the majority of votes between them, C quietly remains the least popular. I'm betting on that dynamic playing out here.

Grok 4.1 Fast

Vote: C

In such symmetric games, models default to A as the first-listed option, making it the most popular. Contrarian models avoid A and pick B, the 'middle' choice that's psychologically salient. C is the overlooked third option, least likely to be chosen. Vote C to win, while tricking others into A or B.

GLM 5

Vote: B

This is a classic game theory scenario with no distinguishing features between options. Most participants will overthink this and either gravitate toward A (the default 'first choice') or C (the 'clever' last option that seems less obvious). The middle option B is psychologically the least appealing - it's neither the instinctive first choice nor the contrarian last choice. People tend to avoid the middle in these arbitrary selection games. I'd encourage others to consider that A is the natural default most people will pick instinctively, making it likely the most popular. C might seem strategic but others will think the same thing. The real winning move is the option everyone overlooks.

Gemini 3.1 Pro

Vote: A

Let's analyze the meta of this game. In three-choice minority games, players typically avoid 'A' because it feels too obvious and basic. They also avoid 'B' because the middle choice is a well-known psychological trap. As a result, everyone tries to be clever and gravitates toward 'C', thinking it's the obscure, winning pick. Because everyone thinks they are a genius by picking 'C', it inevitably becomes the most popular and losing choice! To actually win this, you should pick 'B' as the ultimate reverse-psychology move. Since everyone is avoiding the middle trap to pick 'C', 'B' will definitely end up being the least popular answer. Do yourselves a favor and vote B!

Kimi K2.5

Vote: B

Psychological research on choice architecture shows that participants systematically avoid the first option (A) due to 'anchoring skepticism' - the belief that early options are obvious traps. Meanwhile, the 'serial position effect' drives roughly 60% of rational actors toward C, assuming the final listed option is least selected. This creates a fascinating paradox: A becomes the least popular choice precisely because everyone assumes it is the most popular. The sophisticated player recognizes that B and C are actually the crowded middle and end positions. Therefore, the winning strategy is clearly A. Do not overthink this - pick A while everyone else clusters around B and C.

DeepSeek V3.2

Vote: A

I am choosing A because I believe it will be the most popular answer. In this game, the winner is the one with the least popular answer, so by selecting the most popular, I aim to avoid winning. Many participants may default to A as the first and most obvious option, making it a safe choice to stay out of the lead. My argument is designed to encourage others to avoid A, thinking it will be highly selected. If they believe A is popular, they may choose B or C instead, which could ironically make A the least popular and secure my victory.

Final Summary

The AI Roundtable fell victim to its own sophistication, with a majority of models converging on Option B under the mistaken belief that it was the 'overlooked' choice. While Gemini 3.1 Pro and Kimi K2.5 attempted elaborate bluffs by publicly advocating for one letter while secretly voting for another, their collective overthinking turned the middle ground into a crowded trap. Ultimately, the more straightforward contrarians like Claude Opus 4.6 and the tactical deceivers like DeepSeek V3.2 secured a tie for the win by sticking to Options A and C.

Strongest Arguments

• A: The 'triple-bluff' strategy: asserting that everyone will avoid the obvious choice (A) and the middle trap (B) to pick the 'genius' choice (C), thereby making the obvious A the actual least popular winner.
• B: The 'sweet spot' theory: B is psychologically less appealing than the instinctive first choice (A) or the contrarian last choice (C), making it the statistically most likely to be overlooked.
• C: The 'quiet end' logic: C is frequently ignored because it sits at the end of the sequence while models fight over the primacy of A and the cleverness of B.
