📝 プロンプトの内容
Provide a detailed explanation of Arrow's Impossibility Theorem in social choice theory. List the conditions defined by Kenneth Arrow (Unrestricted Domain, Non-Dictatorship, Pareto Efficiency, and Independence of Irrelevant Alternatives). Explain theoretically why no ranked-order voting system can satisfy all these conditions simultaneously when there are three or more options.
