Iterated Bucklin (alternatively Bucklin-IRV, or BIRV) is a variant of [[Bucklin voting]] whereby the number of top preferences an individual ballot reveals at any point is a function of the winner of the count so far, as opposed to the standard [[Bucklin voting]] procedure by which all ballots reveal the same, progressively increasing number of top preferences until a quota of support is filled by at least one candidate.
Iterated Bucklin was [http://lists.electorama.com/pipermail/election-methods-electorama.com//2020-December/002649.html proposed] by Etjon Basha in December 2020 as an attempt to produce a count that exhibits few practical violations of voting criteria (elicits the greatest degree of sincerity for voters) and the least degree of count complexity, at the cost of not formally meeting many criteria. Iterated Bucklin [http://lists.electorama.com/pipermail/election-methods-electorama.com//2020-December/002649.html violates] [[Condorcet criterion|Condorcet]], [[Later no-harm criterion|Later-No-Harm]], [http://lists.electorama.com/pipermail/election-methods-electorama.com//2020-December/002650.html Later-No-Help] and is not precinct summable. A preliminary simulation of the count’s propensity to violate various criteria was [http://lists.electorama.com/pipermail/election-methods-electorama.com//2020-December/002650.html conducted] by Kevin Venzke.
