STAR voting: Difference between revisions

Line 76:

A modification to STAR that takes degree of preference more into account would be to make each voter's vote in the runoff only as strong as the highest score they gave to any candidate. In other words, a voter who gave their favorite a 3/5 (3 out of 5) would have only 3/5ths of a vote in the runoff, rather than a full vote. This modification allows voters to express less-than-full support for any candidate in both the score round and the runoff.

Example: <blockquote>2 A:1 D:5

3 A:5

6 B:4

Scores are A 17 B 24 D 10, with B pairwise beating A 6 to 5. So the Score and STAR winner is B. But taking into account that those who preferred B over A all have their favorite a maximum of a 4 out of 5, if we weight their runoff votes at 80%, then now B loses the runoff 4.8 to 5. So A wins under modified STAR.<ref>https://forum.electionscience.org/t/star-but-with-weak-votes-in-the-runoff-when-voters-dont-give-any-candidate-the-top-score/615/5</ref></blockquote>[[Instant Runoff Normalized Ratings|IRNR]] is related to STAR in the same way that [[IRV]] is related to [[Top-two runoff]].

Given that STAR is an automatic form of Score voting + Runoff, one can also create an automatic "[[Approval voting]] + Runoff" method by allowing voters to rank or score candidates, and then indicate an [[Condorcet//Approval|approval threshold]] for a particular rank or score such that they'd approve all candidates at that same rank or score or a higher rank or score, and then use the ranks or scores to figure out which of the two most approved candidates is preferred by a majority.
