However, I find ranked choice STV variants are not always ideal for collaborative choice, other than that, they are easier than other alternatives for non-dedicated voters to do. (I actually prefer approval voting over ranked choice as they are even easier for voters and almost as good as ranked choice). If you have a community that is knowledgeable and dedicated enough to spend the time to vote, a Condorcet will often yield a better result.[1] Condorcet basically presents every option as pairs, such as “present vs create”. The pairs are all evaluated. This addresses many properties that the various STV choices can’t do. It isn’t perfect, as a tie can still happen, which requires another approach to break the tie. Another problem is too many choices make for an exponential explosion of pairs (thus my recommendation that it only be used by dedicated & knowledgeable voters as every pair is a choice, so it can take a while). I particularly like Condorcet for fiduciary groups like larger-sized boards (>10), or executive committees, as they have a legal requirement to be dedicated. For more details on Condorcet support see OPAVote: https://www.opavote.com/methods/condorcet-voting My personal wish is that someone could offer me an optional Condorcet pair front end for STV that facilitates me to create a ranked-choice list. For instance, in Manu's poll I only voted for a small number of choices, the rest of which I ignored. I did not even evaluate “create” and if I had would have ranked very low as it was too bland and generic. [1]: Beyond Condorcet being IMHO of the best set of choices given Arrow’s Impossibility Theorem (see https://ieeexplore.ieee.org/document/6483218), I feel Condorcet is also particularly good for choices between people as our socio-psychology often makes other forms of voting for people bi-modal (see an example of what this is in my article on Amazon 5-star voting http://www.lifewithalacrity.com/2006/08/using_5star_rat.html) and helps address that voting about people triggers always voting behavior issues (sometimes unconciously): https://en.wikipedia.org/wiki/Voting_behavior. Unfortunately, Condorcet just requires too much work by the voter to be practical. — Christopher Allen
