This chapter compares majority judgment mechanism to other methods, including first-past-the-post and Borda’s method, among others, in the context of the game of voting. The concept of utilities, which depends on grade distribution of the electorate, is extended to election output. When the identity of the election winner is dependent on the utilities of voters, Condorcet-winner is elected by a large number of strong-equilibria strategy-profiles. The chapter explores best-response correspondence, according to which, if the number of possible equilibria is very small and sometimes unique, the Condorcet-winner emerges as the unique, possible equilibrium outcome and honest votes determine the election outcome.
