Re: DIS: Score Voting

I don’t find a computer simulation of something as subjective as satisfaction 
to be very convincing, even given the relative soundness of the paper itself. 
I’d be against score voting _specifically because_ it appears to encourage - 
and indeed work best with - strategic rather than honest voting.

That said, I am extremely glad to have provoked more discussion about voting 
methods! Thank you for posting this, and I hope you make time to submit a 
proposal.

If everyone votes strategically, then it's still an okay voting system. The
source for proof that it's the best is this image:

What proof are you referring to?  Instant runoff certainly has its
downsides, but so does score voting.  For example, per Wikipedia [1],
the optimal strategy for score voting is usually to give each option
either the minimum or maximum score, which then disadvantages voters
who score the options based on their actual relative preferences.

Draft proposal:

Rule 2528 is amended as follows:
* In the first paragraph, "instant runoff," is replaced by "score voting,".
* Item 3 is replaced by: "For a score voting decision, any list of
score assignments that does not repeat an option; for this purpose, a
"score assignment" is a valid option and a score for that option,
which must be an integer in the range 0 through 10 inclusive."

Rule 955 is amended as follows:
* Item 2 is replaced by: "For a score voting decision, the outcome is
whichever option has the highest score, where the score of an option
is the sum of the scores assigned to that option by valid ballots. In
case of a tie, the vote collector CAN and must, in the announcement of
the decision's resolution, select one of the leaders as the outcome."

Rule 2127 is amended by deleting the paragraph that begins "For an
instant runoff decision,".

Rule 2154 is amended by replacing "instant runoff" with "score voting".

I like the simplicity. I think would support the switch.

it feels like there's a discussion going on involving what exactly single
transferable vote means, so I feel like I should bring up that Score Voting
has mathematically been proven to be better. Is there any reason not to
switch to it?
