Pairwise Sorted Approval is the simplest of a class of Pairwise Sorted Methods.

A voter ranks candidates, and specifies approval, either by using an Approval Cutoff or by ranking above and below a fixed approval cutoff rank.

To determine the winner,

  1. sorted candidates in descending order of approval.
  2. For each candidate, move it higher in the list as long as it pairwise beats the next-higher candidate, and only after all candidates above it have moved upward as far as they can.

This procedure can be used to produce a social ordering. It finds the same winner as Definite Majority Choice.
