An electoral system which reduces the number of wasted votes can be considered desirable on grounds of fairness or on the more pragmatic basis that a voter who feels their vote has made no difference may feel detached from their government or lose confidence in the democratic process. The term "wasted vote" is especially used by advocates of systems like Evaluative Proportional Representation (EPR) in Section 5.5.5 in Proportional Representation, approval voting, the single transferable vote, two round systems or instant-runoff voting which purport to reduce the numbers of such votes.
