IRV occasionally is known as Ware's method just after its inventor, American William Robert Ware. When The one transferable vote (STV) strategy is applied to only one-winner election, it turns into IRV; the government of Ireland has known as IRV "proportional illustration" determined by the fact that the identical ballot variety is used to elect its president by IRV and parliamentary seats by STV, but IRV can be a winner-take-all election strategy.

Australia, a country by using a long history of employing IRV with the election of legislative bodies, has experienced representation in its parliament broadly comparable to that predicted by plurality approaches.

IRV just isn't a proportional voting system. Like all winner-get-all voting approaches, IRV has a tendency to exaggerate the number of seats won by the biggest functions; modest parties without the vast majority aid in any offered constituency are unlikely to get paid seats inside of a legislature, Despite the fact that their supporters is going to be extra more likely to be Component of the final choice amongst The 2 strongest candidates.
