Arrow's Impossibility Theorem Explained
This video explains Arrow's Impossibility Theorem, which proves mathematically that there is no perfect voting system. The video defines "voting system" and goes over the four properties that are part of the theorem: Independence of Irrelevant Alternatives, Pareto Efficiency, Unrestricted Domain, and Non-Dictatorship.
