Majority loser criterion

The majority loser criterion is a criterion to evaluate single-winner voting systems. The criterion states that if a majority of voters prefers every other candidate over a given candidate, then that candidate must not win.

Either of the Condorcet loser criterion or the mutual majority criterion imply the majority loser criterion. However, the Condorcet criterion does not imply the majority loser criterion. Neither does the majority criterion imply the majority loser criterion.

Methods that comply with this criterion include Schulze, Ranked Pairs, Kemeny-Young, Nanson, Baldwin, Coombs, Borda, Bucklin, instant-runoff voting, contingent voting, and anti-plurality voting.

Methods that do not comply with this criterion include plurality, MiniMax, Sri Lankan contingent voting, supplementary voting, approval voting, and range voting.
