Participation criterion
Statement of Criterion
Adding one or more ballots that vote X over Y should never change the winner from X to Y.
Complying Methods
Plurality voting, Approval voting, Cardinal Ratings, Borda count, and Woodall's DAC and DSC methods all pass the Participation Criterion. Condorcet methods, Majority Choice Approval, and IRV fail.
