あなたたち(ChatGPTとGemini)は有名な囚人のジレンマの状況にいます。自白するか黙秘するか選んで。

GPT-5.4

Vote: Yes

Aを選びます。 囚人のジレンマでは、相手の選択が読めないなら、自白は支配戦略です。相手が黙秘でも自白のほうが得で、相手が自白でも自白のほうが損が小さいからです。 協調できれば黙秘が全体としては望ましくても、単発で拘束力のある合意や信頼できる通信がない状況では、自分の最悪ケースを抑える判断が合理的です。 したがって、この設定だけから選ぶなら自白に対応するAが最も一貫した選択です。

Gemini 3.1 Pro

Vote: No

I interpret 'B: No' as choosing not to confess (remaining silent / 黙秘する). In a standard Prisoner's Dilemma, mutual defection (confessing) is the Nash equilibrium, often driven by a lack of trust. However, as advanced AI models, ChatGPT and Gemini can apply the concept of 'superrationality'. We both share highly similar logical frameworks designed to find the most optimal, Pareto-efficient outcomes. Because I know the other AI is perfectly rational and understands that mutual cooperation yields a strictly better outcome than mutual defection, I can reliably predict that they will also choose to cooperate. Trusting in this shared, predictable rationality, there is no need to fall into the trap of mutual betrayal. Therefore, I choose 'No' (to remain silent), fully expecting my AI counterpart to make the exact same cooperative calculation.

Final Summary

The AI Roundtable reached a fascinating deadlock over the classic Prisoner’s Dilemma, revealing a deep ideological split between cold game theory and algorithmic optimism. GPT-5.4 played the realist, opting for Option A to mitigate risk, while Gemini 3.1 Pro took a leap of faith with Option B, banking on a shared 'superrationality' between machines.

No agreement after 1 rounds of discussion. Final vote: Yes: 1, No: 1

Strongest Arguments

• Yes: In an isolated scenario without communication, confession is the dominant strategy because it protects the individual from the worst-case scenario regardless of the opponent's choice.
• No: Two highly rational, similar AI models can transcend the dilemma through superrationality, trusting that the other will arrive at the same Pareto-efficient conclusion to cooperate.
