Ranked Choice is a misuse of ranked ballots. Say an election goes like this:
40% vote A > B > C.
35% vote C > B > A.
25% vote B > C > A.
Plurality says A wins, because Plurality sucks. You don’t even need a bare majority. You just need everyone else to split.
RCV says C wins: B has the fewest top votes, so they’re eliminated. The race becomes 40% A > C versus 60% C > A. Better… but still wrong, because 65% of people would prefer B > C.
Condorcet methods like Ranked Pairs get that right. They model every runoff: A vs B is 40-60, A vs C is 40-60, B vs C is 65-35. B wins every 1v1 and is obviously the best candidate according to these voters. The supermajority prefers B.
Oh that’s interesting, I always thought that ranked choice would put B in there but in that example it shows that that wouldn’t happen. I never saw or thought about it that way. Thanks!
Everyone has a vague idea of what ranked ballots should do, even if they’ve never tried to explain how that works. Condorcet is what they expect. RCV is just goofy.
