How to make one vote count for 10
?I have an article over at BPro that discusses how the IBA results would have changed with a first-past-the-post system, and I use the IBA votes in an instant-runoff method.
To get a bit more technical on the various voting impacts: in this case, it was a clear two-man race, Trout v Donaldson. The vast majority of the voters had these two players somewhere at 1-2. The rest of the players on the ballot were simply noise. And in "ranked" voting (whatever the official term is), you give 10 points for whoever you ranked 1st and 9 points for second, and so on (though in BBWAA MVP, it's 14, then 9). If your ballot shows Trout-Donaldson, you are giving 10 to Trout and 9 to Donaldson. Accepting the rest of the players as noise, this is EXACTLY the same thing as giving 1 to Trout and 0 to Donaldson. Indeed, listing Trout 10th on your ballot, and leaving Donaldson off altogether is IDENTICAL in impact to listing these players 1-2. Therefore, you give 1 more point to Trout than Donaldson.
If you want to give Trout TWO more points than Donaldson, you list them 1-3 or 2-4 or 3-5... or 8-10 or 9 and leave the other guy off the ballot. If you want to give Trout THREE more points than Donaldson, you place Trout 8th and leave Donaldson off the ballot. Four more points for Trout? List Trout 7th and leave Donaldson off. And on and on we go. List Trout 1st, leave Donaldson off the ballot altogether, and you are giving Trout 10 points. And your vote now counts for ten times as much as an honest vote.
Indeed, one guy placing Trout 1st and leaving Donaldson off altogether will exactly cancel out the ten voters placing Donaldson first and Trout 2nd.
I'll come back later in the morning to show the breakdown as to how the BPro readers voted on this.
