I might've said the same 10+ years ago, but now? IRV (and any preferential voting system) is quite close to the voting system for any of the weekly elimination talent shows. You rank people in order, the last one gets knocked out, you try again - with the difference that this all happens at once. Are we really saying that people are too dim to rank their choices in order of preference, or understand the voting system behind some of the most popular TV formats worldwide for the past decade?
