Round 2: We make our second elimination. Fortunately, the bins that received no data were exclusively after the point where the algorithms are guaranteed to be concordant. A majority would be 11 votes. We see that there is a 50% likelihood of concordance when the winner has about one-third of the total vote, and the likelihood increases until eventually reaching 100% after the plurality winner obtains 50% of the vote. With IRV, the result can beobtained with one ballot. Choice E has the fewest first-place votes, so we remove that choice, shifting everyones options to fill the gaps. In a three-candidate election, the third-place candidate in both election algorithms is determined by the first-choice preferences, and thus is always unaffected by the choice of algorithm. (I have not seen that proposed in the U.S.) This might be interpreted as reducing your choice, or forcing you to vote against yourconscience. C, Dulled This study implies that ballot dispersion is a key driver of potential differences in the candidates each voting algorithm elects. C has the fewest votes. This voting method is used in several political elections around the world, including election of members of the Australian House of Representatives, and was used for county positions in Pierce County, Washington until it was eliminated by voters in 2009. In many aspects, there is absolutely no empirical or objective precedent to inform the proper implementation of RCV. Popular elections may be conducted using a wide variety of algorithms, each of which aims to produce a winner reflective, in some way, of the general consensus of the voters. 2. M is elimated, and votes are allocated to their different second choices. The second is the candidate value and incorporates only information related to voters first choice. \hline 1^{\text {st }} \text { choice } & \mathrm{B} & \mathrm{C} & \mathrm{B} & \mathrm{D} & \mathrm{B} & \mathrm{E} \\ The 44 voters who listed M as the second choice go to McCarthy. Transcribed image text: Question 1 Find the winner of this election under the plurality-with-elimination (instant runoff voting) method. Many studies comparing the Plurality and IRV algorithms have focused on voter behavior (Burnett and Kogan, 2015) or have presented qualitative arguments as to why candidates might run different styles of campaigns as a result of different electoral structures (Donovan et al., 2016). In IRV, voting is done with preference ballots, and a preference schedule is generated.

Concordance of election results increased as HHI decreased across bins 1 - 40 before leveling off at 100% after bin 40. The Plurality winner in each election is straightforward. If one of the candidates has more than 50% of the votes, that candidate wins. We dont want uninformed, - It either requires a computer system, or is labor intensive to count by hand, with risk of errors. But another form of election, plurality voting,. Kilgour, D. M., Grgoire, J. and Foley, A. M. (2019) The prevalence and consequences of ballot truncation in ranked-choice elections. It is so common that, to many voters, it is synonymous with the very concept of an election (Richie, 2004). \end{array}\), \(\begin{array}{|l|l|l|} There is still no choice with a majority, so we eliminate again. People are less turned off by the campaign process and, Green Mountain Citizen 2017 Winter Newsletter. The LWVVT has a position in support of Instant Runoff Voting, but we here present a review ofthe arguments for and against it. These situations are extremely uncommon in a two-party system, where the third-party candidate generally garners little support. \hline 1^{\text {st }} \text { choice } & \text { B } & \text { D } \\ We then shift everyones choices up to fill the gaps. Let x denote a discrete random variable with possible values x1 xn , and P(x) denote the probability mass function of x. \hline 4^{\text {th }} \text { choice } & \mathrm{E} & \mathrm{E} & \mathrm{E} & \mathrm{B} & \mathrm{D} & \mathrm{C} \\ The Plurality algorithm, though extremely common, suffers from several major disadvantages (Richie, 2004). The choice with the least first-place votes is then eliminated from the election, and any votes for that candidate are redistributed to the voters next choice. = 24. Australia requires that voters, dont want some of the candidates. We can immediately notice that in this election, IRV violates the Condorcet Criterion, since we determined earlier that Don was the Condorcet winner. Consider the preference schedule below, in which a companys advertising team is voting on five different advertising slogans, called A, B, C, D, and E here for simplicity. Both of these measurements share the same cutoff for guaranteed concordance as their corresponding ballot concentration counterparts. Rhoades, S. A. Consider again this election. The full timeline of ranked-choice voting in Maine explains the path that has led to the use of this method of voting. On the other hand, the temptation has been removed for Dons supporters to vote for Key; they now know their vote will be transferred to Key, not simply discarded. When learning new processes, writing them out by hand as you read through them will help you simultaneously memorize and gain insight into the process. Rep. Brady Brammer, R-Pleasant Grove, said he didn't see much urgency in addressing plurality in elections. A version of IRV is used by the International Olympic Committee to select host nations. Other single-winner algorithms include Approval, Borda Count, Copeland, Instant-Runoff, Kemeny-Young, Score Voting, Ranked Pairs, and Schulze Sequential Dropping. Plurality voting, a voting system in which the person who receives the most votes wins, is currently the predominate form of voting in the United States." In contrast to this traditional electoral system, in an instant runoff voting system, voters rank candidates-as first, second, third and so on-according to their preferences. \hline 3^{\text {rd }} \text { choice } & \mathrm{D} & \mathrm{B} & \mathrm{C} & \mathrm{E} & \mathrm{C} & \mathrm{B} \\ CONs of IRV/RCV It is new - A certain percentage of people don't like change. This voting method is used in several political elections around the world, including election of members of the Australian House of Representatives, and was used for county positions in Pierce County, Washington until it was eliminated by voters in 2009. \end{array}\). Available: www.doi.org/10.1089/1533129041492150. RCV usually takes the form of "instant runoff voting" (IRV). This is a problem. \hline & 3 & 4 & 4 & 6 & 2 & 1 \\ In an instant runoff election, voters can rank as many candidates as they wish. \hline 2^{\text {nd }} \text { choice } & \mathrm{C} & \mathrm{D} & \mathrm{D} & \mathrm{C} & \mathrm{E} & \mathrm{D} \\ There have been relatively few studies that use numerical simulations to test the behavior of election algorithms under different conditions. The plurality with elimination method requires voters to rank their preferences. Instant Runoff Voting (IRV), also called Plurality with Elimination, is a modification of the plurality method that attempts to address the issue of insincere voting. Round 3: We make our third elimination. This is known as the spoiler problem. The reasons for this are unclear and warrant further study. The last video shows the example from above where the monotonicity criterion is violated. \hline Plurality vs. Instant-Runoff Voting Algorithms. Plurality is extremely vulnerable to the spoiler effect so that even candidates with little support can act as spoilers. \hline 1^{\text {st choice }} & \mathrm{B} & \mathrm{C} & \mathrm{B} & \mathrm{D} & \mathrm{B} & \mathrm{E} \\ \(\begin{array}{|l|l|l|l|l|l|} We hypothesize that if the dispersion of voter preferences and ballots increases, then the concordance between Plurality voting and Instant-Runoff Voting should decrease. We find that when there is not a single winner with an absolute majority in the first round of voting, a decrease in Shannon entropy and/or an increase in HHI (represented by an increase in the bin numbers) results in a decrease in algorithmic concordance. By the sixth and final round, the winner beat Santos by about 200 votes and had 51 percent to Santos' 49 percent of the remaining vote. Under plurality with a runoff (PwR), if the plurality winner receives a majority of the votes then the election concludes in one round. \end{array}\). - A certain percentage of people dont like change. The 20 voters who did not list a second choice do not get transferred - they simply get eliminated, \(\begin{array}{|l|l|l|} This continues until a choice has a majority (over 50%). If one of the candidates has more than 50% of the votes, that candidate wins. In IRV, voters mark their preferences on the ballot by putting a 1 next to their first choice, a 2 next to their second choice, and so on. Consider the preference schedule below, in which a companys advertising team is voting on five different advertising slogans, called A, B, C, D, and E here for simplicity. We dont want uninformedpeople coming to exercise their right and responsibility to have a bad experience, or toleave without voting properly. Round 2: We make our second elimination. We then shift everyones choices up to fill the gaps. \hline 1^{\text {st }} \text { choice } & \text { B } & \text { D } \\ The winner held a majority over Santos but his share of . Round 1: We make our first elimination. Instant Runoff Voting (IRV), also called Plurality with Elimination, is a modification of the plurality method that attempts to address the issue of insincere voting. \hline 1^{\text {st choice }} & \mathrm{B} & \mathrm{C} & \mathrm{B} & \mathrm{D} & \mathrm{B} & \mathrm{E} \\ The vetting is less clear - In the U.S., we have very few requirements for what a person must do to run for office and be on a ballot. Concordance rose from a 56% likelihood in bins where ballots had the highest levels of HHI to a 100% likelihood of concordance in the boundary case. W: 37+9=46. If enough voters did not give any votes to. A Plural Voting system, as opposed to a single winner electoral system, is one in which each voter casts one vote to choose one candidate amongst many, and the winner is decided on the basis of the highest number of votes garnered by a candidate. . \end{array}\). We also prove that electoral outcomes are guaranteed to be concordant above a certain level of ballot concentration. By doing so, it simplifies the mechanics of the election at the expense of producing an outcome that may not fully incorporate voter desires. C has the fewest votes. If no candidate has has more than 50% of the votes, a second round of plurality voting occurs with plurality elections or instant runoff voting grade 10 1170l Page 3 of 12 Instant Runoff Voting. \(\begin{array}{|l|l|l|l|l|l|l|l|} \(\begin{array}{|l|l|l|l|l|l|l|} With primaries, the idea is that there is so much publicity that voters in later primaries, and then in the general election, will have learned the candidates weaknesses and be better informed before voting. Instant runoff is designed to address several of the problems of our current system of plurality voting, where the winning candidate is simply the one that gets the most votes. Now B has 9 first-choice votes, C has 4 votes, and D has 7 votes. McCarthy (M) now has a majority, and is declared the winner. People are less turned off by the campaign process andhappier with the election results. \hline 2^{\text {nd }} \text { choice } & \mathrm{C} & \mathrm{D} & \mathrm{D} & \mathrm{C} & \mathrm{B} \\ \hline 2^{\text {nd }} \text { choice } & \mathrm{M} & \mathrm{B} & & \mathrm{G} & \mathrm{B} & \mathrm{M} & \\ McCarthy gets 92 + 44 = 136; Bunney gets 119 + 14 = 133. Market share inequality, the HHI, and other measures of the firm composition of a market. Still no majority, so we eliminate again. Now B has 9 first-choice votes, C has 4 votes, and D has 7 votes. For the Shannon entropy, this point is at approximately 0.6931, meaning that elections with Shannon entropy lower than 0.6931 are guaranteed to be concordant. \(\begin{array}{|l|l|l|l|l|l|l|l|} However, we can calculate the HHI and Shannon entropy of these first choices and show how their dispersion relates to the probability of concordant election outcomes, had they been the first round in an IRV election. Alternatively, we can describe voters as designating their first and second choice candidates, since their third choice is the remaining candidate by default. In contrast, as voters start to consider a wider range of candidates as a viable first-choice, the Plurality and IRV algorithms start to differ in their election outcomes. Therefore, voters cast ballots that voice their opinions on which candidate should win, and an algorithm determines which candidate wins based on those votes. Plurality Under the plurality system, the candidate with the most votes wins, even if they do not have a majority, and even if most voters have a strong preference against the candidate. No one yet has a majority, so we proceed to elimination rounds. 100% (1 rating) As we can see from the given preference schedule Number of voters 14 8 13 1st choice C B A 2nd choice A A C 3rd choice B . Ballot (and voter) exhaustion under instant runoff voting: An examination of four ranked-choice elections, Electoral Studies, 37, 41-49. \end{array}\), G has the fewest first-choice votes, so is eliminated first. Thus, greater preference dispersion results in lower concordance as hypothesized. Ranked-choice voting is not a new idea. We conducted a numerical simulation in which we generated one million hypothetical elections, calculated the ballot dispersion in each election, and compared the winner of the election using the Plurality and the IRV algorithms. In a Runo Election, a plurality vote is taken rst. Public Choice. Round 2: We make our second elimination. If this was a plurality election, note that B would be the winner with 9 first-choice votes, compared to 6 for D, 4 for C, and 1 for E. There are total of 3+4+4+6+2+1 = 20 votes. \end{array}\). A plurality voting system is an electoral system in which the winner of an election is the candidate that received the highest number of votes. In an instant runoff election, voters can rank as many candidates as they wish. 2. Notice that the first and fifth columns have the same preferences now, we can condense those down to one column. This is similar to the idea of holding runoff elections, but since every voters order of preference is recorded on the ballot, the runoff can be computed without requiring a second costly election. However, employing the IRV algorithm, we eliminate candidate B and redistribute the votes resulting in Candidate C winning under IRV. The concordance of election results based on the ballot Shannon entropy is shown in Figure 1. The calculations are sufficiently straightforward and can be performed in a Microsoft Excel spreadsheet as described below. -Voter Participation -Do We Really Need the Moon? \hline Round 2: K: 34+15=49. If you look over the list of pros above you can see why towns that use IRV tend to have better voter turnout than before they started the IRV. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. If the latest poll is right, and the referendum on question 5 passes, the state's current electoral system will be scrapped and replaced with a method called ranked-choice voting (RCV). For example, the Shannon entropy and HHI can be calculated using only voters first choice preferences. In order to determine how often certain amounts of entropy and HHI levels relate to concordance, we need many elections with identical levels of entropy and HHI. If any candidate has a majority (more than 50%) of the first preference votes, that candidate is declared the winner of the election. We calculate two values for each of these statistics. A majority would be 11 votes. If this was a plurality election, note . Another particularly interesting outcome is our ability to estimate how likely a Plurality election winner would have been concordant with the IRV winner when the Plurality winningpercentage is the only available information. The last video shows the example from above where the monotonicity criterion is violated. The 214 people who voted for Don have their votes transferred to their second choice, Key. The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. This continues until a choice has a majority (over 50%). \hline & 136 & 133 \\ This criterion is violated by this election. In IRV, voting is done with preference ballots, and a preference schedule is generated. In each election for each candidate, we add together the votes for ballots in which the candidate was the first choice. In the most notable cases, such as elections for president or governor, there can only be a single winner. \hline 1^{\text {st }} \text { choice } & \mathrm{B} & \mathrm{C} & \mathrm{B} & \mathrm{D} & \mathrm{B} & \mathrm{E} \\ - Voters can vote for the candidate they truly feel is best, - Instead of feeling compelled to vote for the lesser of two evils, as in plurality voting, voters can honestly vote for, (to narrow the field before the general election), (to chose a final winner after a general election, if no candidate has a majority, and if the law requires a majority for that office). K wins the election. \hline 2^{\text {nd }} \text { choice } & \text { D } & \text { B } \\ With IRV, the result can be, (get extreme candidates playing to their base). If no candidate has has more than 50% of the votes, a second round of plurality voting occurs with a designated number of the top candidates. Yet he too recommends approval voting, and he supports his choice with reference to both the system's mathematical appeal and certain real-world considerations. If a candidate wins a majority of first-preference votes, he or she is declared the winner. Cambridge has used its own version for municipal elections since 1941, and across the U.S., it will be employed by more than a dozen cities by 2021 . In addition to each simulated election having both a Plurality and IRV winner, it also has a distinct voter preference concentration, which we describe in terms of Shannon entropy and HHI. Higher degrees of voter preference concentration, or lower Shannon entropy, tends to increase the potential for winner concordance. In the following video, we provide the example from above where we find that the IRV method violates the Condorcet Criterion in an election for a city council seat. Choice A has the fewest first-place votes, so we remove that choice. Available: www.doi.org/10.1002/j.1538-7305.1948.tb00917.x. \hline & 3 & 4 & 4 & 6 & 2 & 1 \\ Burnett, C. M. and Kogan, V. (2015). Available: www.doi.org/10.1007/BF01024300. D has now gained a majority, and is declared the winner under IRV. Concordance rose from a 75% likelihood in bins where ballots had the highest levels of Shannon entropy to a 100% likelihood of concordance in the boundary case. However, under Instant-Runoff Voting, Candidate B is eliminated in the first round, and Candidate C gains 125 more votes than Candidate A. Lets return to our City Council Election. The first electoral system is plurality voting, also known as first-past-the-post; the second is the runoff system, sometimes called a two-round system; and the third is the ranked choice or the instant runoff. Denition 1 is consistent with typical usage of the term for plurality elections: For a single-winner plurality contest, the margin of victory is the difference of the vote totals of two In this election, Carter would be eliminated in the first round, and Adams would be the winner with 66 votes to 34 for Brown. Single transferable vote is the method of Instant runoff election used for multi-winner races such as the at-large city council seats. D has now gained a majority, and is declared the winner under IRV. In one such study, Joyner (2019) used machine learning tools to estimate the hypothetical outcome of the 2004 presidential election had it been conducted using the IRV algorithm. plurality system, electoral process in which the candidate who polls more votes than any other candidate is elected. \end{array}\). \hline 3^{\text {rd }} \text { choice } & & \mathrm{D} & \mathrm{C} & & & \mathrm{D} \\ Thus, Bob Kiss won this election using instant runoff voting. If this was a plurality election, note that B would be the winner with 9 first-choice votes, compared to 6 for D, 4 for C, and 1 for E. There are total of 3+4+4+6+2+1 = 20 votes. Still no majority, so we eliminate again. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. As shown in Figure 5, the likelihood of winner concordance approaches one hundred% when one candidate achieves close to a majority of first-choice preferences. Find the winner using IRV. Concordance rose from a 75% likelihood in bins where ballots had the highest levels of HHI to a 100% likelihood of concordance in the boundary case.
