Methods of Social Choice
This Demonstration illustrates the outcomes of various social choice procedures. These procedures are used to reach a decision when there are more than two alternatives and none of those alternatives is the first choice of a majority of the voters. Quite often, for the given preference lists of the voters, the different procedures choose different winners. In addition to plurality, the standard methods of the Borda count, sequential pairwise voting with a fixed agenda (abbreviated SPFVA in the Demonstration), and the Hare method are illustrated. The option to have a dictator is included, as is information on whether a given set of voter preferences has a Condorcet winner.
