Is IRV a proven and accepted voting method?
Yes. It is used by millions of voters in government elections in the U.S. and around the world, and is a voting procedure detailed in current editions of Robert’s Rules of Order, called “preferential voting.” It has also been adopted by the American Political Science Association (college professors), who know a thing or two about elections, to elect their national president. It was originally invented by a professor at the Massachusetts Institute of Technology around 1870, and has been used by millions of voters in governmental elections around the world for generations, especially in English-speaking countries, including Australia, England, and the Republic of Ireland.
