|Voting patterns and effects|
Voting is a method for a group, such as a meeting or an electorate, in order to make a collective decision or express an opinion usually following discussions, debates or election campaigns. Democracies elect holders of high office by voting. Residents of a place represented by an elected official are called "constituents", and those constituents who cast a ballot for their chosen candidate are called "voters". There are different systems for collecting votes, but while many of the systems used in decision-making can also be used as electoral systems, any which cater for proportional representation can only be used in elections.
In smaller organizations, voting can occur in different ways. Formally via ballot to elect others for example within a workplace, to elect members of political associations or to choose roles for others. Informally voting could occur as a spoken agreement or as a verbal gesture like a raised hand or electronically.
In a democracy, a government is chosen by voting in an election: a way for an electorate to elect, i.e., choose, among several candidates for rule.In a representative democracy voting is the method by which the electorate appoints its representatives to government, and by which the elected representatives make decisions. In a direct democracy, voting is the method by which the electorate directly make decisions, turn bills into laws, etc.
A majority vote is a formal expression of an individual's choice for or against some motion (for example, a proposed resolution); for or against some ballot question; or for a certain candidate, selection of candidates, or political party. A preferential vote may allow the voter and/or elected representative to cast one, some or many preferences. In elections, many countries use a secret ballot, a practice to prevent voters from being intimidated and to protect their political privacy.
Voting often takes place at a polling station; it is voluntary in some countries, compulsory in others, such as Australia.
When making a decision, those concerned seek one outcome: a majority opinion for a single decision or a single prioritisation. There are several ways in which voters and/or elected representatives may seek to identify that majority opinion. There is the simple, weighted or consociational majority vote. There are other multi-option procedures as well; these include two-round voting, the alternative vote AV, (which is also known as instant run-off voting IRV, and the single transferable vote STV), approval voting, a Borda Count BC, the Modified Borda Count MBC, and the Condorcet rule, nearly all of which are also used as electoral systems.They are outlined below.
There are rather more electoral systems, because of proportional representation, PR. Those concerned might want to elect just one person, or maybe a committee, or maybe an entire parliament. In electing a president, there is usually just the one winner, although the original system in the USA also elected the runner-up as a vice-president. In electing a parliament, either each of many small constituencies can elect a single representative, as in Britain; or each of quite a few multi-member constituencies may elect a few representatives, as in Ireland; or the entire country can be treated as the one constituency, as in The Netherlands.
Different voting systems use different types of votes. Plurality voting does not require the winner to achieve a voting majority or more than fifty percent of the total votes cast. In a voting system that uses a single vote per race, when more than two candidates run, the winner may commonly have less than fifty percent of the vote.
A side effect of a single vote per race is vote splitting, which tends to elect candidates that do not support centrism, and tends to produce a two-party system. One of many other procedures to a single-vote system is approval voting.
To understand why a single vote per race tends to favor less centric candidates, consider a simple lab experiment where students in a class vote for their favorite marble. If five marbles are assigned names and are placed "up for election", and if three of them are green, one is red, and one is blue, then a green marble will rarely win the election. The reason is that the three green marbles will split the votes of those who prefer green. In fact, in this analogy, the only way that a green marble is likely to win is if more than sixty percent of the voters prefer green. If the same percentage of people prefer green as those who prefer red and blue, that is to say, if 33 percent of the voters prefer green, 33 percent prefer blue, and 33 percent prefer red, then each green marble will only get eleven percent of the vote, while the red and blue marbles will each get 33 percent, putting the green marbles at a serious disadvantage. If the experiment is repeated with other colors, the color that is in the majority will still rarely win. In other words, from a purely mathematical perspective, a single-vote system tends to favor a winner that is different from the majority.
With approval voting, voters are encouraged to vote for as many candidates as they approve of, so the winner is much more likely to be any one of the five marbles because people who prefer green will be able to vote for every one of the green marbles.
A development on the 'single vote' system is to have two-round elections, or repeat first-past-the-post. This system is most common around the world. In most cases, the winner must receive a majority, which is more than half.and if no candidate obtains a majority at the first round, then the two candidates with the largest plurality are selected for the second round. Variants exist on these two points: the requirement for being elected at the first round is sometimes less than 50%, and the rules for participation in the runoff may vary.
A third procedure is the single round instant-runoff voting system (Also referred to as Alternative vote or Single Transferable Vote or Preferential voting ) as used in some elections in Australia, the USA and, in its PR format, in Ireland. Voters rank each candidate in order of preference (1,2,3,4 etc.). Votes are distributed to each candidate according to the preferences allocated. If no single candidate has 50% of the vote, then the candidate with the fewest votes is excluded and their votes redistributed according to the voter's nominated order of preference. The process repeating itself until a candidate has 50% or more votes. The system is designed to produce the same result as an exhaustive ballot but using only a single round of voting.
In its PR format, PR-STV, in say a four-seater constituency, every candidate with a quota of 1st preferences will be elected. A quota in this instance is 20% + 1 of the valid vote. If a candidate has more than a quota, his/her surplus will be distributed to the other candidates, in proportion to all of that candidate's 2nd preferences. If there are still candidates to be elected, the least popular is eliminated, as above in AV or IRV, and the process continues until four candidates have reached a quota.
In the Quota Borda System, QBS, Emerson P (2012)the voters also cast their preferences, 1,2,3,4... as they wish. In the analysis, all 1st preferences are counted; all 2nd preferences are counted; and after these preferences have been translated into points as per the rules of an MBC, the candidates' points are also counted. Seats are awarded to any candidates with a quota of 1st preferences; to any pair of candidates with two quotas of 1st/2nd preferences; and if seats are still to be filled, to those candidates with the highest MBC scores.
In a voting system that uses a multiple votes, the voter can vote for any subset of the alternatives. So, a voter might vote for Alice, Bob, and Charlie, rejecting Daniel and Emily. Approval voting uses such multiple votes.
In a voting system that uses a ranked vote, the voter has to rank the alternatives in order of preference. For example, they might vote for Bob in the first place, then Emily, then Alice, then Daniel, and finally Charlie. Ranked voting systems, such as those used in Australia and Ireland, use a ranked vote.
In a voting system that uses a scored vote (or range vote), the voter gives each alternative a number between one and ten (the upper and lower bounds may vary). See cardinal voting systems.
Some "multiple-winner" systems such as the Single Non-Transferable Vote, SNTV, used in Afghanistan may have a single vote or one vote per elector per available position. In such a case the elector could vote for Bob and Charlie on a ballot with two votes. These types of systems can use ranked or unranked voting and are often used for at-large positions such as on some city councils.
Finally, the Condorcet rule, used (if at all) in decision-making. The voters or elected representatives cast their preferences on one, some or all options, 1,2,3,4... as in PR-STV or QBS. In the analysis, option A is compared to option B, and if A is more popular than B, then A wins this pairing. Next, A is compared with option C, then D, and so on. Likewise, B is compared with C, with D etc. The option which wins the most pairings, (if there is one), is the Condorcet winner.
Most of the time, when the citizens of a country are invited to vote, it is for an election. However, people can also vote in referendums and initiatives. Since the end of the eighteenth century, more than five hundred national referendums (including initiatives) were organized in the world; among them, more than three hundred were held in Switzerland.Australia ranked second with dozens of referendums.
Most referendums are binary. The first multi-option referendum was held in New Zealand in 1894, and most of them are conducted under a two-round system. New Zealand had a five-option referendum in 1992, while Guam had a six-option plebiscite in 1982, which also offered a blank option, in case some voters wanted to (campaign and) vote for a seventh option.

Results may lead at best to confusion, at worst to violence and even civil war, in the case of political rivals. Many alternatives may fall in the latitude of indifference—they are neither accepted nor rejected. Avoiding the choice that most people strongly reject may sometimes be at least as important as choosing the one that they most favor.
There are social choice theory definitions of seemingly reasonable criteria that are a measure of the fairness of certain aspects of voting, including non-dictatorship, unrestricted domain, non-imposition, Pareto efficiency, and independence of irrelevant alternatives but Arrow's impossibility theorem states that no voting system can meet all these standards.
To ensure fair voting and preventing the misuse of the microblogging platform, Twitter announced for adding a feature for users to report content that misleads voters. This announcement came when general elections are going to be held in India and some other countries.
Negative voting allows a vote that expresses disapproval of a candidate. For explanatory purposes, consider a hypothetical voting system that uses negative voting. In this system, one vote is allowed, with the choice of either for a candidate, or against a candidate. Each positive vote adds one to a candidate's overall total, while a negative vote subtracts one, arriving at a net favorability. The candidate with the highest net favorability is the winner. Note that not only is a negative total possible, but also, a candidate may even be elected with 0 votes if enough negative votes are cast against their opponents.
Under this implementation, negative voting is no different from a positive voting system, when only two candidates are on the ballot. However, in the case of three or more candidates, each negative vote for a candidate counts positively towards all of the other candidates.
Consider the following example:
Three candidates are running for the same seat. Two hypothetical election results are given, contrasting positive and negative voting. Both polling accuracy and voter turnout are assumed to be 100 percent.
|Candidates||A voters||B voters||C voters||Net total|
|Candidates||A voters||B voters||C voters||Net total|
Election results with positive voting:
A-voters, with the clear advantage of 40%, logically vote for Candidate A. B-voters, unconfident of their candidate's chances, split their votes exactly in half, giving both Candidates A and C 15% each. C-voters, also logically vote for their candidate. A is the winner with 55%, C at 45%, and B 0%.
Election results with negative voting:
A-voters again, with the clear advantage of 40%, logically vote for Candidate A. B-voters, split exactly in half. Each B-voter decides to vote negatively against their least favorite candidate, with the reasoning that this negative vote allows them to express approval for the two other candidates. C-voters also decide to vote negatively against Candidate A, reasoning along similar lines. Candidate B is the winner with 0 votes. Enough negative votes were cast against Candidate B's opponents, resulting in negative totals. Candidate A, despite having polled at 40%, winds up with -5%, offset due to the aggregate 45% of negative votes cast by B and C voters. Candidate C ends up with -15%.
Proxy voting is the type of voting where a registered citizen who can vote passes on his or her vote to a different voter or electorate legitimately.
In South Africa, there is a strong presence of anti-voting campaigns by poor citizens. They make the structural argument that no political party truly represents them. For instance, this resulted in the "No Land! No House! No Vote!" Campaign which becomes very prominent each time the country holds elections.The campaign is prominent among three of South Africa's largest social movements: the Western Cape Anti-Eviction Campaign, Abahlali baseMjondolo, and the Landless Peoples Movement.
Other social movements in other parts of the world also have similar campaigns or non-voting preferences. These include the Zapatista Army of National Liberation and various anarchist-oriented movements.
It is possible to make a blank vote, carrying out the act of voting, which may be compulsory, without selecting any candidate or option, often as an act of protest. In some jurisdictions, there is an official none of the above option and it is counted as a valid vote. Usually, blank and null votes are counted (together or separately) but are not considered valid.
Modern political science has questioned whether average citizens have sufficient political information to cast meaningful votes. A series of studies coming out of the University of Michigan in the 1950s and 1960s argued that voters lack a basic understanding of current issues, the liberal–conservative ideological dimension, and the relative ideological dilemma.
Studies from other institutions have suggested that the physical appearance of candidates is a criterion upon which voters base their decision.
Christadelphians, Jehovah's Witnesses, Old Order Amish, Rastafarians, the Assemblies of Yahweh, and some other religious groups, have a policy of not participating in politics through voting.Rabbis from all Jewish denominations encourage voting; some even consider it a religious obligation.
Whenever several people who do not all agree need to make some decision, voting is a very common way of reaching a decision peacefully. The right to vote is usually restricted to certain people. Members of a society or club, or shareholders of a company, but not outsiders, may elect its officers, or adopt or change its rules, in a similar way to the election of people to official positions. A panel of judges, either formal judicial authorities or, say, judges of the competition, may make decisions by voting. A group of friends or members of a family may decide which film to see by voting. The method of voting can range from formal submission of written votes, through show of hands, voice voting or audience response systems, to informally noting which outcome seems to be preferred by more people.
According to Robert's Rules of Order, a widely used guide to parliamentary procedure, the bases for determining the voting result consist of two elements: (1) the percentage of votes that are required for a proposal to be adopted or for a candidate to be elected (e.g. more than half, two-thirds, three-quarters, etc.); and (2) the set of members to which the proportion applies (e.g. the members present and voting, the members present, the entire membership of the organization, the entire electorate, etc.).An example is a majority vote of the members present and voting.
The voting result could also be determined using a plurality, or the most votes among the choices.
In addition, a decision could be made without a formal vote by using unanimous consent.

A voting method is the way in which people cast their votes in an election or referendum. There are several different methods in use around the world.
Deliberative assemblies—bodies that use parliamentary procedure to arrive at decisions—use several methods of voting on motions (formal proposal by a member or members of a deliberative assembly that the assembly takes 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. The assembly could decide on the voting method by adopting a motion on it. Different legislatures may have their voting methods.
The most common voting method uses paper ballots on which voters mark their preferences. This may involve marking their support for a candidate or party listed on the ballot, or a write-in, where they write out the name of their preferred candidate if it is not listed.
An alternative paper-based system known as ballot letters is used in Israel, where polling booths contain a tray with ballots for each party contesting the elections; the ballots are marked with the letter(s) assigned to that party. Voters are given an envelope into which they put the ballot of the party they wish to vote for, before placing the envelope in the ballot box. The same system is also implemented in Latvia.
Machine voting uses voting machines, which may be manual (e.g. lever machines) or [[Electronic voting|electronic] is displayed on screen.
In some countries people are allowed to vote online. Estonia was one of the first countries to use online voting: it was first used in the 2005 local elections.
Many countries allow postal voting, where voters are sent a ballot and return it by post.
In contrast to a secret ballot, an open ballot takes place in public and is commonly done by a show of hands. An example is the Landsgemeinde system in Switzerland, which is still in use in the cantons of Appenzell Innerrhoden, Glarus, Grisons, and Schwyz.
In The Gambia, voting is carried out using marbles, a method introduced in 1965 to deal with illiteracy.Polling stations contain metal drums painted in party colors and emblems with candidates' photos attached to them. Voters are given a marble to place in the drum of their chosen candidate; when dropped into the drum, a bell sounds to register the vote. To avoid confusion, bicycles are banned near polling booths on election day. If the marble is left on top of the drum rather than placed in it, the vote is deemed invalid.
A similar system used in social clubs sees voters given a white ball to indicate support and a black ball to indicate opposition. This led to the coining of the term blackballing.
Some votes are carried in person if all the people eligible to vote are present. This could be by a show of hands or keypad polling.
Approval voting is a single-winner electoral system where each voter may select ("approve") any number of candidates. The winner is the most-approved candidate. It is related to score voting in which voters give each option a score on a scale, and the option with the highest total of scores is selected. It is distinct from plurality voting in which a voter may choose only one option among several, whereby the option with the most votes is chosen—even absent a majority.
Plurality voting is an electoral system in which each voter is allowed to vote for only one candidate, and the candidate who polls more than any other counterpart is elected. In a system based on single-member districts, it may be called first-past-the-post (FPTP), single-choice voting, simple plurality or relative/simple majority. In a system based on multi-member districts, it may be referred to as winner-takes-all or bloc voting.
The two-round system is a voting method used to elect a single candidate, where voters cast a single vote for their preferred candidate. The election proceeds to a second round only if in the first round no candidate has received a simple majority of votes cast, or at least some other prescribed percentage. In the second round, usually only the two candidates who received the most votes in the first round, or those candidates who received above a prescribed proportion of the votes, would be candidates in the second round. Any remaining candidate is free to withdraw from the second round.
The single transferable vote (STV) is a voting system designed to achieve or closely approach proportional representation through the use of multiple-member constituencies and each voter casting a single ballot on which candidates are ranked. The preferential (ranked) balloting allows transfer of votes to produce proportionality, to form consensus behind select candidates and to avoid the waste of votes prevalent under other voting systems. Another name for STV is multi-winner ranked-choice voting.
In voting methods, tactical voting occurs in elections with more than two candidates, when a voter supports another candidate more strongly than their sincere preference in order to prevent an undesirable outcome.
A Condorcet method is an election method that elects the candidate who wins a majority of the vote in every head-to-head election against each of the other candidates, that is, a candidate preferred by more voters than any others, whenever there is such a candidate. A candidate with this property, the pairwise champion or beats-all winner, is formally called the Condorcet winner. The head-to-head elections need not be done separately; a voter's choice within any given pair can be determined from the ranking.
Cumulative voting is a multiple-winner cardinal voting method intended to promote more proportional representation than winner-take-all elections. Cumulative voting is used frequently in corporate governance, where it is mandated by some (7) U.S. states. (See e.g., Minn. Stat. Sec. 302A.111 subd. 2 .)
The independence of irrelevant alternatives (IIA), also known as binary independence or the independence axiom, is an axiom of decision theory and various social sciences. The term is used with different meanings in different contexts; although they all attempt to provide an account of rational individual behavior or aggregation of individual preferences, the exact formulations differ from context to context.
The Australian electoral system comprises the laws and processes used for the election of members of the Australian Parliament. The system presently has a number of distinctive features including compulsory enrolment, compulsory voting, majority-preferential instant-runoff voting in single-member seats to elect the lower house, the House of Representatives, and the use of the single transferable vote proportional representation system to elect the upper house, the Senate.
The random ballot, random dictator, single stochastic vote, or lottery voting is an electoral system in which an election is decided on the basis of a single randomly selected ballot. Whilst appearing superficially chaotic, the system has the potential to retain the most attractive characteristics of both first past the post and proportional representation systems in elections to multi-constituency bodies. It was first described in 1984 by Akhil Reed Amar.
Open list describes any variant of party-list proportional representation where voters have at least some influence on the order in which a party's candidates are elected. This is as opposed to closed list, which allows only active members, party officials, or consultants to determine the order of its candidates and gives the general voter no influence at all on the position of the candidates placed on the party list. Additionally, an open list system allows voters to select individuals rather than parties. Different systems give the voter different amounts of influence. The voter's choice is usually called preference vote; the voters are usually allowed one or more preference votes to the open list candidates.
The participation criterion is a voting system criterion. Voting systems that fail the participation criterion are said to exhibit the no show paradox and allow a particularly unusual strategy of tactical voting: abstaining from an election can help a voter's preferred choice win. The criterion has been defined as follows:
The majority criterion is a single-winner voting system criterion, used to compare such systems. The criterion states that "if one candidate is ranked first by a majority of voters, then that candidate must win".
BC-STV is the proposed voting system recommended by the Citizens' Assembly on Electoral Reform in October 2004 for use in British Columbia, and belongs to the single transferable vote family of voting systems. BC-STV was supported by a majority of the voters in a referendum held in 2005 but the government had legislated that it would not be bound by any vote lower than 60 percent in favour. Because of the strong majority support for BC-STV, the government elected to stage a second referendum in 2009, but with increased public funding for information campaigns to better inform the electorate about the differences between the existing and proposed systems. The leadership of both the "yes" side and the "no" side were assigned by the government. The proposal was rejected with 60.9 percent voting against, vs. 39.1 percent in favour, in the 2009 vote.
The single transferable vote (STV) is a voting system based on proportional representation and ranked voting. Under STV, an elector's vote is initially allocated to his or her most-preferred candidate. After candidates have been either elected (winners) by reaching quota or eliminated (losers), surplus votes are transferred from winners to remaining candidates (hopefuls) according to the surplus ballots' ordered preferences.
There are a number of complications and issues surrounding the application and use of single transferable vote proportional representation that form the basis of discussions between its advocates and detractors.
The Borda count is a family of single-winner election methods in which voters rank options or candidates in order of preference. The Borda count determines the outcome of a debate or the winner of an election by giving each candidate, for each ballot, a number of points corresponding to the number of candidates ranked lower. Once all votes have been counted, the option or candidate with the most points is the winner. The Borda count is intended to elect broadly acceptable options or candidates, rather than those preferred by a majority, and so is often described as a consensus-based voting system rather than a majoritarian one.
Instant-runoff voting (IRV), also sometimes referred to as the alternative vote (AV), preferential voting, or, in the United States, ranked-choice voting (RCV), though these names are also used for other systems, is a type of ranked preferential voting counting method used in single-seat elections with more than two candidates.
An electoral system or voting system is a set of rules that determine how elections and referendums are conducted and how their results are determined. Political electoral systems are organized by 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. Political electoral systems are defined by constitutions and electoral laws, are typically conducted by election commissions, and can use multiple types of elections for different offices.
Electoral systems are the rules for conducting elections. Comparisons between different systems can focus on different aspects: on suffrage or rules for voter eligibility; on candidate eligibility and the rules governing political parties; on the way elections are scheduled, sequenced, and combined; or on the rules for determining the winner within a given election.
