Question
Larry, Curly and Moe all ran for Head Mucky-Muck at Band Camp. The campers voted by writing out their preference ballots on a piece of paper and then handing them to the camp counselor. The counselor counted the votes, performed the voting method and found that Larry would win. Just to make sure she counted the votes again. While doing this she found that she had missed two votes that had Larry in first place. So she performed the voting method again with Larry starting with two more 1st place votes. This time she found that Moe won. a) Explain which fairness criterion violation is illustrated in this example. b) Based on your answer to part a) which voting method or methods (plurality, Copeland's, Instant Runoff, Borda count) could the teacher have been using?Explanation / Answer
a)Larry got two additional first preference votes and still lost .This means that Monotonicity criterion is violated in this example.
b) Teacher could have been using Instant runoff method of voting. Adding two additional votes may have changed who Larry faces in the runoff . Hence he may have lost to Moe in the run off.
