https://rangevoting.org/Burlington.html https://rangevoting.org/Burlington.html here's a real life election with a Condorcet winner in which IRV elected some other candidate.
The reason there are not more examples like this one is that most governments don't release enough information about ballots in IRV elections.
- SilasX 8y agoAs soon as I can find some time to work through that, I'll give my thoughts. But ... is there maybe a truncated explanation of the general dynamic there?
- Sohcahtoa82 8y agoBasically, imagine you have three candidates: A, B, and C, and there are 50 voters, and the votes come in like this: 100 - A > C > B 100 - B > C > A 40 - C > A > B 10 - C > B > A After round 1 of IRV, candidates A and B each have 100 votes, C has 50. C gets knocked out, 40 votes move to A, 10 votes move to B. A now has 140 votes, and B has 110, and A is declared the winner. The problem is that the B > C > A don't get their second choice considered. Why does this matter? Look at it when you put the votes into pairs. A vs B: 140 people think A > B. 110 think B > A. A vs C: 100 people think A > C. 150 think C > A. B vs C: 110 people think B > C. 140 think C > B. C is actually the more popular candidate, but C LOSES using IRV!
