The Non-compulsory support criterion was devised in 2005 by Thomas Smith. A voting method satisfies the Non-compulsory Support criterion if it provides a means for the voter to exclude one or more candidates from supportive ranking or rating, and by doing so, not help the non-supported candidates. Methods that satisfy this criterion include Approval voting, Range voting, Bucklin voting, and voter truncated Borda count. Methods that do not satisfy this criterion include Condorcet methods, plurality voting, standard Borda count and Single Transferable Vote methods. For example, Approval and Range voting allow the voter to rate any candidate with a zero, which effectively does not give those candidates any advantage. Voter-truncated Borda count allows the voter to not rank any candidate, which gives them no points in the tallies.
