Explain Arrow's Impossibility Theorem. Arrow's Impossibility Theorem states that majority rules is an impossible goal to achieve in a fair election. Arrow's Impossibility Theorem states that having an electoral vote satisfies the four fairness criteria better than a plurality vote. Arrow's Impossibility Theorem states that no voting system can satisfy all four fairness criteria in all cases. Arrow's Impossibility Theorem states that it is imperative to find a voting system that satisfies all four criteria in a democracy
