with elections under the single-transferable vote

While FPTP is trash, that system is kinda trash, too: if a candidate would beat all others 1-on-1 (Condorcet winner), then should that candidate win? Not according to single transferable vote/instant run-off.

Example

  • A > B > C: 2
  • C > B > A: 2
  • B > C > A: 1

Who wins according to instant run-off? C. Who wins against every opponent 1-on-1? B.

Other methods also fail.

There are better methods: this nice table compares voting methods by a wide range of properties.
