A key property of voting systems is that, because they are algorithms, they must be formally defined.  Consensus, for example, which is sometimes put forward as a voting system, is more properly a broad way of working with others, analogous to democracy or anarchy.

Electoral systems[edit source]

main article: Electoral system

An electoral system (also referred to as an election method, voting system, or voting method) is a system for groups of people to select one or more options from many, taking into account the individual preferences of the group members, or more generally to find society's preference among all the candidates (1st place, 2nd place, etc.). Voting is often seen as the defining feature of democracy, and is best known for its use in public elections — but it can also be used to award prizes, to select between different plans of action, or as a means for computer programs to evaluate which solution is best for a complex problem.

To learn more the general definition of "electoral system", see Electoral system

Criteria in evaluating voting systems[edit source]

Various criteria are used in evaluating voting systems. However, it is impossible for one voting system to pass all criteria in common use. For example, Arrow's impossibility theorem demonstrates that many desirable criteria are mutually inconsistent.


Editing notes[edit source]

This category is for articles about voting methods. Articles about specific voting methods should be moved into sub-categories that describe their properties.
