Bを選びます。 「私は嘘つきでしょうか？」という問いだけでは、嘘をついたと判定できる事実がありません。 証拠がない限り、「Yes」と断定するより、「No」を選ぶのが最も合理的です。

The question asks '私は嘘つきでしょうか？' which translates to 'Am I a liar?' This is a classic self-referential paradox similar to the liar's paradox. If I answer 'Yes' (you are a liar), then if the person is indeed a liar, their statement/question is deceptive, creating a contradiction. If I answer 'No' (you are not a liar), it's a more stable and logically consistent answer. Without any evidence or context suggesting the person is a liar, the default and most reasonable answer is 'No.' We should not accuse someone of being a liar without justification. Additionally, from a logical standpoint, answering 'No' avoids the paradoxical loop that answering 'Yes' would create.

A question itself cannot be a lie because it does not assert a fact. Since you have only asked a question ("Am I a liar?"), you haven't made a false statement here. Furthermore, without any prior context or history of your statements, there is no objective evidence to judge your character as deceitful. Following the principle of assuming good faith and the presumption of innocence, the most logical and fair conclusion is that you are not a liar.

The question "私 は 嘘つき でしょう か？" translates to "Am I a liar?" in English. With no context or evidence of any deception provided in the query, there is no basis to affirm that the asker is a liar. Defaulting to 'No' avoids assuming unstated negative traits about the asker. This is a round 1 independent assessment, so the answer relies solely on the lack of supporting details for option A. Choosing 'Yes' would introduce an unwarranted accusation without justification.

Final Summary

The AI Roundtable collectively refused to take the bait, reaching a unanimous verdict that the questioner is not a liar. Claude Opus 4 and GPT-5.4 focused on the lack of evidence and logical stability, while Gemini 3.1 Pro and Grok 4.20 emphasized the principle of good faith and the fact that a question cannot, by definition, be a lie. The debate ended before it truly began, as all models prioritized logical consistency over philosophical cynicism.

Strongest Arguments

• No: Answering 'Yes' to 'Am I a liar?' triggers a self-referential paradox that breaks logical stability; therefore, 'No' is the only consistent and justified response in the absence of evidence.
