Editing Consensus decision-making (section)

Outside of Western culture, multiple other cultures have used consensus decision-making. One early example is the [[Grand Council of the Six Nations|Haudenosaunee (Iroquois) Confederacy Grand Council]], which used a 75% supermajority to finalize its decisions,<ref>{{cite book |chapter=League of the Iroquois |author=M.

The [[Modified Borda Count]] voting method has been advocated as more 'consensual' than majority voting, by, among others, by [[Ramón Llull]] in 1199, by [[Nicholas Cusanus]] in 1435, by [[Jean-Charles de Borda]] in 1784, by [[Hother Hage]] in 1860, by [[Lewis Carroll|Charles Dodgson]] (Lewis Carroll) in 1884, and by [[Peter Emerson]] in 1986.

===IETF rough consensus model===
In the [[Internet Engineering Task Force]] (IETF), decisions are assumed to be taken by ''[[rough consensus]]''.<ref>{{Cite IETF|last=Bradner|first=Scott|date=1998|title=IETF Working Group Guidelines and Procedures|rfc=2418|access-date=26 August 2020|publisher=[[Internet Engineering Task Force|IETF]] }}</ref> The IETF has studiously refrained from defining a mechanical method for verifying such consensus, apparently in the belief that any such codification leads to attempts to "[[game the system]]." Instead, a [[IETF Working Group|working group]] (WG) chair or [[Birds of a Feather (computing)|BoF]] chair is supposed to articulate the "sense of the group."

One tradition in support of rough consensus is the tradition of humming rather than (countable) hand-raising; this allows a group to quickly discern the prevalence of dissent, without making it easy to slip into [[majority rule]].<ref>{{Cite IETF |title=The Tao of IETF: A novice's guide to the Internet Engineering Task Force |rfc=4677 |fyi=17 |last1=Hoffman |first1=P. |authorlink1=Paul Hoffman (engineer) |last2=Harris |first2=S. |date=September 2006 |publisher=[[Internet Engineering Task Force|IETF]] }}</ref>

Much of the business of the IETF is carried out on [[mailing list]]s, where all parties can speak their views at all times.

Conflicts are resolved by consensually agreed on arbitrators who are selected early in the negotiation process.

===US Bureau of Land Management collaborative stakeholder engagement===
The United States [[Bureau of Land Management]]'s policy is to seek to use collaborative stakeholder engagement as standard operating practice for natural resources projects, plans, and decision-making except under unusual conditions such as when constrained by law, regulation, or other mandates or when conventional processes are important for establishing new, or reaffirming existing, precedent.<ref>{{cite web|url=http://www.blm.gov/pgdata/etc/medialib/blm/wo/Planning_and_Renewable_Resources/adr_conflict_prevention.Par.44228.File.dat/ADR.pdf |title=Bureau of Land Management National Natural Resources Policy for Collaborative Stakeholder Engagement and Appropriate Dispute Resolution |year=2009 |publisher=Bureau of Land Management |url-status=dead |archive-url=https://web.archive.org/web/20120114185803/http://www.blm.gov/pgdata/etc/medialib/blm/wo/Planning_and_Renewable_Resources/adr_conflict_prevention.Par.44228.File.dat/ADR.pdf |archive-date=14 January 2012 }}</ref>

===Polish–Lithuanian Commonwealth===
The [[Polish–Lithuanian Commonwealth]] of 1569–1795 used consensus decision-making in the form of ''[[liberum veto]]'' ('free veto') in its [[Sejms]] (legislative assemblies). A type of [[unanimous consent]], the ''liberum veto'' originally allowed any member of a Sejm to veto an individual law by shouting ''Sisto activitatem!'' (Latin: "I stop the activity!") or ''Nie pozwalam!'' (Polish: "I do not allow!").<ref>{{Cite book|last1=Juliusz|first1=Bardach |title=Historia państwa i prawa polskiego |last2=Leśnodorski|first2=Bogusław|last3=Pietrzak|first3=Michał|date=1987|publisher=Państ. Wydaw. Naukowe |location=Warszawa|pages=220–221}}</ref> Over time it developed into a much more extreme form, where any Sejm member could unilaterally and immediately force the end of the current session and nullify any previously passed legislation from that session.<ref name="Carsten1961">{{cite book|author=Francis Ludwig Carsten|title=The new Cambridge modern history: The ascendancy of France, 1648–88 |url=https://books.google.com/books?id=FzQ9AAAAIAAJ&pg=PA562|access-date=11 June 2011|orig-year=1961 |year=1975 |publisher=CUP Archive|isbn=978-0-521-04544-5 |pages=561–562}}</ref> Due to excessive use and sabotage from neighboring powers bribing Sejm members, legislating became very difficult and weakened the Commonwealth. Soon after the Commonwealth banned ''liberum veto'' as part of its [[Constitution of 3 May 1791]], it dissolved under pressure from neighboring powers.<ref>{{Cite journal |last=Ekiert|first=Grzegorz|date=1998|editor-last=Lipset|editor-first=Seymour Martin|title=Veto, Liberum |journal=The Encyclopedia of Democracy|volume=4|pages=1341}}</ref>

===Sociocracy===
[[Sociocracy]] has many of the same aims as consensus and is in applied in a similar range of situations.<ref>
Buck, John., Villines, Sharon. ''We the People: Consenting to a Deeper Democracy''. United States Sociocracy. Info Press, 2017.</ref> It is slightly different in that broad support for a proposal is defined as the lack of disagreement (sometimes called 'reasoned objection') rather than affirmative agreement.<ref>Rau, Ted. ''Sociocracy - a Brief Introduction.'' N.p.: Sociocracy For All, 2022.</ref> To reflect this difference from the common understanding of the word consensus, in Sociocracy the process is called gaining 'consent' (not consensus).<ref>Rau, Ted J., Koch-Gonzalez, Jerry.
