Ranked choice voting is not good enough, it has far too many flaws like not amounting to majority rule. In fact it only encourages fringe candidates who have more to gain and end up getting disproportionately represented in when voting ends
- matthewmacleod 10y agoThis system is used for many elections globally, and my understanding is that it's widely considered to be quite fair. I'm struggling to understand your specific objections.
- mojuba 10y agoI think the problem (at least theoretically) is that second-choice votes are not weighted. It could've been e.g. 1 for first choice, 0.5 for second and so on. Because obviously your second choice candidate is not as good to you as the first one, but some not-so-good candidates can get more votes. In fact I can even see some potential patterns for manipulation here.
- matthewmacleod 10y agoThat isn't a problem; the impact of your vote is inherent in the ranking, so lower preferences are automatically "worth less" than higher ones. I don't see a particular pattern that would allow for manipulation. AFAIK it's fairly resistant to tactical voting and manipulation by withdrawal.
- mojuba 10y agoIs it so in case of Maine though?
- ClayShentrup 10y agoLudicrous. http://scorevoting.net/TarrIrv.html http://scorevoting.net/TarrIrv.html And irrelevant, since IRV performs worse with 100% honest voters than Score or Approval with 100% strategic.

- jimhefferon 10y agoBut there are many results showing that manipulation is NP complete. So Arrow's work is only a first take on the entire story.

- matthewmacleod 10y agoApproval voting is fabulous. Why have I never seen this discussed before?
- sp332 10y agoThis is less of a problem if there are more than two established parties that can expect to get the vast majority of the votes. With multiple real choices, smaller parties don't have to be "fringe".

- dublinben 10y agoIt may not be perfect, but it's better than the current process.
