Equally Weighted Vote: Difference between revisions

One generalization of the Equally Weighted Vote for the multi-winner or proportional context is [[Vote unitarity|vote unitarity]]. The basic idea is that the vote should stay equally weighted throughout the election tabulation. A voters influence on electing subsequent winners should directly depend on the amount of support they gave for prior winners. This means that the vote weight is conserved throughout the process.

There is an important nuance to this with regards to [[Surplus Handling]]; if, say, every voter gives one of the winners a perfect score, then instead of everyone's vote having no influence on the other winners, vote unitarity tries to ensure some kind of proportional decrease in voting power such that every voter still has a the correct amount of influence on the remaining winners. The simplest implementation of this is with [[Sequentially Spent Score]].

In summary, there is a proportional relationship between how much support the voters give to the winners and the amount of influence that is removed from the voters, to ensure that every voter has a chance to fairly elect someone they prefer. The prominent [[Reweighted Range Voting]] method fails vote unitarity.
