Pairwise preference: Difference between revisions

Another criticism is that it can be harder to do [[pairwise counting]] than it is to count the vote in other methods, such as [[Approval voting]]. The [[Rated pairwise preference ballot#Rated or ranked preference]] implementation can potentially mitigate this criticism, because for every voter who indicates a rated preference, at most only one piece of information need be collected from their ballot for every candidate they marked (their score for the candidate), rather than several pairwise preferences.

 

The nature of pairwise preferences prevents direct comparisons of candidates from two separate elections, unlike with [[rated method]]<nowiki/>s or other methods. For example, it is possible to compare Reagan's [[approval rating]] in polls from the 1980s to Obama's in the 2010s without having to ask voters about both in the same election/poll, but their pairwise matchup against each other can't be evaluated like that.
