Voting methods in deliberative assembliesDeliberative assemblies – bodies that use parliamentary procedure to arrive at decisions – use several methods of voting on motions (formal proposal by members of a deliberative assembly that the assembly take certain action). The regular methods of voting in such bodies are a voice vote, a rising vote, and a show of hands. Additional forms of voting include a recorded vote and balloting. Voice voteRobert's Rules of Order Newly Revised (RONR) states that a voice vote (viva voce) is the usual method of voting on any motion that does not require more than a majority vote for its adoption.
Electoral systemAn electoral system or voting system is a set of rules that determine how elections and referendums are conducted and how their results are determined. Electoral systems are used in politics to elect governments, while non-political elections may take place in business, non-profit organisations and informal organisations. These rules govern all aspects of the voting process: when elections occur, who is allowed to vote, who can stand as a candidate, how ballots are marked and cast, how the ballots are counted, how votes translate into the election outcome, limits on campaign spending, and other factors that can affect the result.
Compulsory votingCompulsory voting, also called universal civic duty voting or mandatory voting, is the requirement that registered voters participate in an election. In practice, one only needs to check-in at a polling place, submit a blank ballot, or provide an excused reason, such as disability, illness, age, travel, a natural disaster, or religious objections. 21 countries, including 11 in Latin America, had compulsory voting laws as of January 2023, with the countries enforcing their laws having much higher turnout (high 80's vs.
Strategic votingStrategic voting, also called tactical voting, sophisticated voting or insincere voting, occurs in voting systems when a voter votes for a candidate or party other than their sincere preference to prevent an undesirable outcome. For example, in a simple plurality election, a voter might gain a better outcome by voting for a less preferred but more generally popular candidate. Gibbard's theorem shows that all single-winner voting methods encourage strategic voting, unless there are only two options or dictatorial (i.
Cardinal votingCardinal voting refers to any electoral system which allows the voter to give each candidate an independent evaluation, typically a rating or grade. These are also referred to as "rated" (ratings ballot), "evaluative", "graded", or "absolute" voting systems. Cardinal methods (based on cardinal utility) and ordinal methods (based on ordinal utility) are two main categories of modern voting systems, along with plurality voting. There are several voting systems that allow independent ratings of each candidate.
Preferential votingPreferential voting or preference voting (PV) may refer to different election systems or groups of election systems: Ranked voting methods, all election methods that involve ranking candidates in order of preference (American literature) Optional preferential voting Instant-runoff voting, referred to as "preferential voting" in Australia and as "ranked choice voting" in United States, is one type of ranked voting method. Contingent vote (the top-two variant of IRV) Single transferable vote (referred to as "
Alternative vote plusThe alternative vote plus (AV+), or alternative vote top-up, is a semi-proportional voting system. AV+ was devised by the 1998 Jenkins Commission which first proposed the idea as a system that could be used for elections to the Parliament of the United Kingdom. As the name suggests, AV+ is an additional member system which works in two parts: the 'AV' part and the 'plus' part. As in the alternative vote system, candidates are ranked numerically in order of preference.
Multiwinner approval votingMultiwinner approval voting, also called approval-based committee voting, is a multi-winner electoral system that uses approval ballots. Each voter may select ("approve") any number of candidates, and multiple candidates are elected. The number of elected candidates is usually fixed in advance. For example, it can be the number of seats in a country's parliament, or the required number of members in a committee. Multiwinner approval voting is an adaptation of approval voting to multiwinner elections.
History and use of instant-runoff votingInstant-runoff voting (IRV) is a voting method used in single-seat elections with more than two candidates. Instead of voting only for a single candidate, voters in IRV elections can rank the candidates in order of preference. Ballots are initially counted for each elector's top choice, losing candidates are eliminated, and ballots for losing candidates are redistributed until one candidate is the top remaining choice of a majority of the voters.
Proxy votingProxy voting is a form of voting whereby a member of a decision-making body may delegate their voting power to a representative, to enable a vote in absence. The representative may be another member of the same body, or external. A person so designated is called a "proxy" and the person designating them is called a "principal". Proxy appointments can be used to form a voting bloc that can exercise greater influence in deliberations or negotiations.
