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.  Methods that satisfy this criterion include [[Approval voting]], [[Range voting]], [[Bucklin voting]], voter truncated [[Borda count]] and standard [[Single Transferable Vote]] methods.  Methods that do not satisfy this criterion include [[Condorcet methods]], [[plurality voting]], standard [[Borda count]] and non-truncatable STV methods. For example, Approval and Range voting allow the voter to rate any candidate with a zero, which effectively does not give the candidates so rated any support.  Voter-truncated Borda count allows the voter to not rank any candidate, which gives them no support.

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. Methods that satisfy this criterion include Approval voting, Range voting, Bucklin voting, voter truncated Borda count and standard Single Transferable Vote methods. Methods that do not satisfy this criterion include Condorcet methods, plurality voting, standard Borda count and non-truncatable STV methods. For example, Approval and Range voting allow the voter to rate any candidate with a zero, which effectively does not give the candidates so rated any support. Voter-truncated Borda count allows the voter to not rank any candidate, which gives them no support.
