Wikimedia and Wikipedia elections are held using a voting system equivalent to Explicit approval voting, 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 = S/(S+O).
Approval voting is generally equivalent to 2-level Score voting (where the levels are "0" and "1"). Wikimedia's variant is equivalent to 2-level Score voting where voters may explicitly abstain, and the default choice is to abstain. The levels in Wikimedia's system imply (−1, +1) rather than (0, 1), so they may be affected by the psychological consequences of disapproval voting.[1]
Results
The Wikimedia Foundation has used this method for Board of Trustees and Funds Dissemination Committee elections in 2013, 2015, and 2017, after previously using Approval voting and Schulze method.
Wikipedia uses this in a non-binding way for Administrator nominations,[2] etc.
If tallied using normal Score voting rules (where O=0, N=1, S=2), the 2015 Wikimedia Board election would have had a different winner, with the candidate in 4th place moving up to 2nd. The 2017 Board and 2015 FDC elections would have had a different top-3 order, but the same 3 candidates would have won.
In all 8 elections from 2013-2017, the most common vote was Neutral, which was cast about twice as often as Support, which in turn was cast about twice as often as Oppose. Winners typically receive 70–85% support.
