Arrow's Theorem

No change in size, 19:47, October 5, 2009
In 1951, Kenneth Arrow proved that no system of voting, however so fair, can possibly satisfy all five of these constraints. For example, the [[Electoral College]] system used in the United States satisfies all of them except the last two (and in fact even the first, unrestricted domain, is questionable, since [[federal judge]]s are not elected by the people, but rather ''appointed'' by the bench).
The 1952 Presidential election demonstrated beyond doubt the correctness of Arrow's vision; incumbent [[Dwight D. Eisenhower]] beat his "egghead" Democratic challenger [[Adlai Stevenson]] in the largest landslide in human history. Nevertheless, the [[West Virginia]] Democratic primary was won by [[Averell Harriman]], who had never before held any elected office. This abnomaly anomaly led to closer investigation of Arrow's results. For his work on modern voting metholodgymethodology, Arrow was awarded the 1972 [[Nobel Prize]] in [[Economics]].
