[['''Approval Methods]]''' are [[voting methods]] that require each voter to separate alternatives in a given election into two complimentary sets, the "A set" and the "-A set".<ref name="A set">An "A set" consists of the alternatives that have the trait that is requested in the election. For example, in approval voting, voters are asked which alternatives they approve. Thus, the A set contains approved alternatives. In disapproval voting, voters are asked which alternatives they disapproved, thus the A set contains disapproved alternatives.</ref> Whichever alternative occurs the most (or least) in A sets of voters wins the election.* Such voting methods are called approval methods because they are all very similar to the most famous example of this type of voting, namely [[approval voting]]. Other examples of approval methods include [[acceptability voting]], [[consensus voting]], [[disapproval voting]], [[happiness voting]], and [[utilitarian voting]].
== Methods ==
Other examples of approval methods include:
* [[acceptability voting]]
* [[consensus voting]]
* [[disapproval voting]]
* [[happiness voting]]
* [[utilitarian voting]]
See [[:Category:Approval voting]] for a full list of approval-based methods documented on [[electowiki]].
== Goals ==
The goals of different approval methods vary. For example, [[consensus voting]] seeks to elect the alternative that the greatest number of voters express the desire to form a consensus around. [[Happiness voting]] seeks to maximize the number of voters who are happy with the result of the election.
Similarly, one might get different results in the same election depending on whether or not acceptability, or approval, or consensus, or disapproval, or any other approval method is used.
