It’s easy to get bad results in ranked choice with some gamesmanship. This is how someone with 10% support wins an election… Happened a few times now in the US with ranked choice. Basically you want to hear your campaign as “second choice” as an unknown playing both sides. Seems to work at least once, but then you have people calling to remove the system.
It requires much more political knowledge to vote effectively, and we already have “egirl said to vote for Xi backed candidate” problems.
Voting theory has a vast literature. A sample result (due to Gil Kalai): If there are three candidates, we assume all of the above axioms except for voting system rationality, and all voters vote randomly, then a rational outcome can only be ob- tained at most 91.92...% of the time. (By comparison, simple majority vote yields a rational outcome 91.22..% of the time, when the number of voters approaches infinity; this seems to be due to Gulibaud). So it seems that voting paradoxes are not isolated to a pathological set of scenarios of infinitesimal probability, but are a genuine and non-trivial difficulty inherent in voting systems.
Of course people don't vote 'randomly', but still interesting.
