Explicit approval voting: Difference between revisions

Line 1:

Wikimedia and Wikipedia elections are held using a [[Ratings ballot|rated voting system]] in which voters must choose ''Support'', ''Oppose'', or ''Neutral'', for every candidate. The winner is the candidate with the highest support percentage: the highest proportion of ''Support'' votes out of combined ''Support'' and ''Oppose'' votes = <math>S \over S+O</math>.

This is ~~mathematically~~ ~~equivalent~~ to 2-level [[Score voting]] with averaging, though the abstain votes are explicit rather than implicit, ~~and~~ ~~the~~ levels ~~are essentially~~ (−1, +1) rather than (0, 1), so they ~~are~~ affected by the psychological consequences of [[disapproval voting]].

This is somewhat similar to 2-level [[Score voting]] with averaging, though the abstain votes are explicit rather than implicit. The levels imply (−1, +1) rather than (0, 1), so they may be affected by the psychological consequences of [[disapproval voting]].<ref>See also [[W:Combined approval voting#Properties|Wikipedia:Combined approval voting#Properties]], in particular [[W:Combined approval voting#cite%20ref-7|the Baujard citation]]</ref>

The Wikimedia Foundation has used this method for Board of Trustees and Funds Dissemination Committee elections in [https://meta.wikimedia.org/wiki/Wikimedia_Foundation_elections_2013/Results 2013], [https://meta.wikimedia.org/wiki/Wikimedia_Foundation_elections_2015/Results 2015], and [https://meta.wikimedia.org/wiki/Wikimedia_Foundation_elections/2017/Results 2017], after previously using [[Approval voting]] and [[Schulze method]]. Wikipedia uses this in a non-binding way for Administrator nominations,<ref>[[W:Wikipedia:Requests for adminship#Decision%20process|w:Wikipedia:Requests for adminship#Decision process]]</ref> etc.
