Abstract: Roughly speaking, Arrow's theorem states that in an election with more than two candidates, there is no "reasonable" voting rule that gives a rational outcome. I will discuss this and related theorems, as well as giving a Fourier-theoretic proof of Arrow's theorem which sheds light on how likely rational outcomes are for any voting rule.
