Instant runoff voting and single transferable voting (IRV/STV) are the only alternative voting methods that fail more of Arrow’s Fairness criteria than plurality voting does because increasing the number of votes for a candidate may cause that candidate to lose, whereas otherwise the candidate would have won!
1. IRV/STV remove the right cast a vote with a positive effect on a candidate’s chances of winning because it is non-monotonic (increasing the number of votes for a candidate may cause that candidate to lose, whereas the candidate otherwise would have won). See this video:

2. IRV/STV remove the right to participate in the final decision of who wins the election by eliminating voters’ ballots prior to the final counting round. The more candidates, the more voters are eliminated prior to the final counting round.
3. IRV/STV remove the right to have one’s votes counted equally and fairly with all other voters’ votes because only voters supporting the least popular candidates as their 1st choice are assured of having their 2nd choice candidate counted when their 1st choice candidate looses.
4. In comparison with top‐two runoff elections, IRV/STV remove the right to elect majority winners. San Francisco had to eliminate its legal right to elect majority winners when it adopted IRV/STV because STV routinely elects winners with far less than 50% of the votes.
5. IRV/STV remove the right to a transparent, verifiable election process with a decentralized, simple counting process that can be easily manually counted and audited.
6. IRV/STV removes the right to have an economical election process.
7. IRV/STV removes the right to change one’s mind between the primary and general election and to have time to get to know the candidates.
8. Violates civil rights of already disenfranchised groups. See Instant Runoff Voting – Voting Civil Rights
A well‐funded misnomered group called Fair Vote, led by Rob Richie, has ties to an Internet voting software company and funds misleading IRV/STV promotional ad campaigns in the United States. Because IRV/STV gives voters of the least popular candidates the most power to decide which candidates are eliminated, counting their 2nd choices first, IRV/STV tend to elect extreme right or extreme left candidates, eliminating centrist majority-favorites. Many other alternative, fair, proportional electoral methods are available that preserve voter rights, precinct count-ability, and election transparency including approval and party list methods. This “reform” threatens the integrity, accuracy, and fairness of US elections.
