DESCRIPTION:Abstract: Arrow’s theorem states that the only voting scheme 
 satisfying a few natural axioms is a dictatorship.\nKalai’s quantitative
  Arrow theorem shows that even relaxing some of these assumptions doesn’
 t help.\nWe show that this is not an isolated phenomenon, by proving a soc
 ial choice “duck test”:\n<< Every approximate polymorphism is a
 pproximately a polymorphism. >>\nThe techniques combine Jones’ reg
 ularity lemma with the colorfully named “It Ain’t Over Till It’s Ove
 r”.\n\nJoint work with Yaroslav Alekseev.
