[EM] a question about apportionment

[Juho Laatu]

Luckily Condorcet can use both ranking and rating style ballots (because rankings can always be derived from the more complex rating information). If one uses ratings, voting in Condorcet is easier than in Range in the sense that the voter need not care what numeric scale one uses. The first guess is good enough. Ratings A=1 B=2 C=3, A=1 B=2 C=9 and A=1 B=6 C=9 are equal in Condorcet.

It is difficult to say how much a typical voter would spend time and effort to consider strategic aspects when voting. In Range the scale that one uses is important. Ballots A=1 B=2 C=9 and A=1 B=9 C=9 have a very different strategic impact. In Condorcet a typical voter need not care about strategies while in Range a typical voter should consider what the optimal strategy is (unless the Range voter wants to cast a "sincere" vote without any wish to cast a strong strategic vote, and unless strategies would become usable in some Condorcet election).

Sincere voting in Range may thus be easy. Sincere ratings in Condorcet should be as easy or easier. In competitive Range elections every voter should consider what strategy tho choose (and how to rig the vote accordingly) while in Condorcet one may assume that regular voters need not worry about strategies.

The evidence is pretty clear that it is easier for most people to rate candidates on an absolute scale - whether numeric or verbal - rather than ranking them relative to each other. That is true despite the fact that it is illogical, that in some sense it should be easier to give a ranked vote which contains less information. But the fact remains: people can usually vote faster, with less ballot spoilage, and with less self-reported difficulty, under Range as compared to Condorcet.
