[EM] Voter's Choice with various ballotings

[MIKE OSSIPOFF]

I've just tried to post this, but when I did, I received a reply from
eskimo.com, giving me instructions on subscribing & unsubscribing.
A message that I sent later posted, and this message didn't, and so
I'm assuming that it won't post, and so I'm re-sending it:


>I like Voter's Choice for situations where people don't agree on a
>voting system. Of course if they don't agree on a balloting system, then
>voters could be invited to fill whatever combination of ballots that they 
>want to: Ranking, Approval ballot, CR ballot, Dyadic Approval
>ballot, etc.
>
>But if a voter only makes out one kind of ballot, we can infer
>the other ballots from it. If it sounds undemocratic to interpret
>someone's ballot in that way, I emphasize that someone's (say) Approval
>ballot is only for the purpose of guiding the Plurality vote placement
>of people who want to place it according to Approval.
>
>Say someone only votes a ranking. With only that information, we
>assume he'd give Approval votes to his highest-ranked half of the
>alternatives. We assume that his CR vote is strategically consistent
>with that Approval vote, and that he gives maximum points to the
>alternatives he'd vote for in Approval, and minimum points to those
>alternatives that he wouldn't vote for in Approval.
>
>Say someone only votes CR ratings. We assume that he ranks the alternatives 
>in the order of his ratings of them. If his ratings
>are strategic, with some maximum and the rest minimum, then of course
>we give his Approval vote to the alternatives to which he gave
>maximum points. If his ratings are nonstrategic, with varying point
>assignments, then we consider it a sincere set of ratings, rather than
>a strategic one, and so we make out his Approval ballot in the
>especially sincere 0-info way: He votes for all the alternatives that
>he rates above the mean.
>
>Say someone votes only an Approval ballot. For CR, we have him give
>maximum points to the alternatives that he voted for in Approval, and
>minimum points to the others. For his ranking, we put all his Approved
>alternatives in a shared 1st place rank position.
>
>I re-emphasize that this isn't undemocratic, because these other ballots
>are only for the purpose of guiding the Plurality vote placement of
>people who want to do so using those kinds of ballots.
>
>So Voter's Choice is flexible when a voter doesn't make out each kind
>of ballot.
>
>Of course a sincere ranking is the easiest kind of ballot to make
>out, and it should be emphasized that that's perfectly sufficient,
>so that no one will be discouraged from voting by the belief that he/she
>has to make out a ballot of each kind.
