Talk:Instant-runoff voting: Difference between revisions

: The former example looks like a later-no-harm failure. I don't think your variation 1 of the latter example shows later-no-help failure (as the voters change their ballots from A to C), but the second does.

: You can fix [[Left, Center, Right|LCR-type]] center squeeze by passing Condorcet, but this will automatically fail all three of later-no-help, later-no-harm, and favorite betrayal. Some such methods could possibly be called IRV - e.g. [[Benham's method]] or [[BTR-IRV]]. But it's pretty difficult to say at what point a fixed IRV method is no longer IRV.

: I don't know if it's possible to pass later-no-harm, later-no-help, and do the right thing in a center squeeze situation. While Condorcet rules out the two LNHs, it could be the case that a weaker criterion still fixes center squeeze; and this criterion could possibly be compatible with the LNHs. But nobody on the election-methods list has come up with such a method. [[User:Kristomun|Kristomun]] ([[User talk:Kristomun|talk]]) 19:06, 4 January 2024 (UTC)
