Supermajority rules can avoid Arrow's theorem at the cost of being poorly-decisive (i.e. frequently failing to return a result). In this case, a threshold that requires a 2 / 3 {\displaystyle 2/3} majority for ordering 3 outcomes, 3 / 4 {\displaystyle 3/4} for 4, etc. does not produce voting paradoxes .
