election_title: "P3 manipulated — the mild version: three adjacent swaps, no burial, same result"
scenario_description: |-
  The manipulation that should worry us more than the book's. The complete reversal is a curiosity — no real voter submits their preferences backwards. But the SAME voter can achieve the SAME outcome with ordinary compromising: submit Dublin>Athens>Bergen>Cork>Edinburgh. That is three adjacent swaps. Nothing is buried, the sincere last choice Edinburgh stays last, and only the compromise candidate Dublin is lifted. Dublin goes 4-0 and wins outright. Exhaustively, 52 of the 119 alternative rankings available to this voter strictly improve their result (44 decided outright or by margin, 8 more only after the lot). Note this is COMPROMISING, not burial — Ranked Robin's documented resistance to burial is untouched and remains true, which makes this worse news rather than better, because compromising is the strategy ordinary voters actually reach for.
