Criteria - FairVote and Equal.Vote
Both FairVote and Equal.Vote have proposed criteria for measuring the political viability and efficacy of proposed voting reforms. As we all discuss various reform options, it'd be really great to at least agree at the outset on how we measure the reform options going forward.
FairVote's 3 Criteria:
Does the method violate the most basic principle of majority rule? In an election with two candidates, we believe the candidate preferred by a majority should always win.
Does the method require the winner to have core support? We believe a winner should be at least one voter’s first choice, meaning they would receive more than 0% in current rules.
Does the method promote sincere voting? Voters should be likely to vote sincerely, according to the method’s rules, and not lose out to tactical voters who vote insincerely.
Equal.Vote's 5 Criteria:
Equality: Does the voting system provide an equal weight vote to every voter?
Accuracy: How accurately does the voting system reflect the will of the people?
Simplicity: How easy is the system for voters to understand and cast ballots, and how easy is it for elections officials to tabulate and hand-recount?
Expressiveness: Can the voter express a nuanced opinion on the outcome?
Honesty: Can the voter safely express her honest opinion on the ballot, and likewise, to what level does the system disincentivize voters from strategically voting insincerely in order to produce a better outcome?
What are the right criteria to use for measurement? Do these capture the essence? Are any unnecessary? What is missing?
