“Define success for yourself, given Arrow’s Impossibility Theorem” explains different voting methods, including plurality voting, run-off voting, sequential run-off, Borda count, and dictatorship, and explains how Kenneth Arrow’s Impossibility Theorem proves that, in an election with three or more candidates, the only fair voting system is a dictatorship. That is, every voting method other than a dictatorship has a known problem with fairness. Mathematics students and enthusiasts are encouraged to consider the many “candidates” for defining “success” in mathematical and life pursuits before letting their vote be the only vote in electing a personal definition of success. This way, Arrow’s Impossibility Theorem assures a fair outcome. At the chapter’s end, readers may check their understanding by working on a problem. A solution is provided.
