The frequency and severity of spoiler effects depends substantially on the voting method. Instant-runoff or ranked-choice voting (RCV), the two-round system (TRS), and especially first-past-the-post (FPP) without winnowing or primary elections[citation needed] are sensitive to spoilers.[4][5][6][7] Majority-rule (or Condorcet) methods are only rarely affected by spoilers, which are limited to rare[8][9] situations called cyclic ties.[8][9][10] Rated voting systems are not subject to Arrow's theorem, allowing them to be spoilerproof so long as voters' ratings are consistent across elections.[2][11][12][13]
