voting example

[mindstalk]

Poll on an imaginary election:

34 A > S > B > C
32 B > S > C > A
33 C > S > A > B
1 S > A > B > C

Of the four candidates, which do you think should win?

Keep in mind Arrow's impossibility theorem: There is *no* voting system that satisfies a short list of plausible-looking, indeed weak-looking, requirements.

No ranked system anyway. There seems debate about score voting.

But that doesn't mean all the systems are equally bad, else we wouldn't bother trying to replace plurality. And I think the proof is less about system flaws than the nature of collective preference. There may not be a Condorcet winner and then the right choice isn't obvious. But IRV doesn't even pick a Condorcet winner when one clearly exists.
