The best voting rules are inclusive, well centered, and decisive.
The results can make a group more popular, stable and quick.

What happens when a policy pendulum swings?

What's Wrong? ↓
The Northwestern U.S. was ripped apart for many years as forestry policies were reversed again and again. Hasty logging in times of weak regulation wasted resources. Sudden limits on logging bankrupted some workers and small businesses. The policy pendulum swings; it cuts down forests and species, families and towns.
Businesses and agencies often lose money and power when a council changes hands and changes laws. Repeated reversals are a major cause of war-like politics.
Can we end such raging or silent tragedies? Better tools give real hope; we can stop the tragedies caused by the old voting tools.
Will their votes have any effect?
But as soon as three candidates run for one office, the situation becomes more complicated. Then a yes-no vote is no longer suitable.
Sometimes what we want is not the election of a solitary official. We want to elect a whole council that represents all the voters. Then we do not need a system of dividing voters into winners and losers. Instead, we need a way of condensing them, in the right proportions, into their chosen leaders.
Such a council (or budget) receives far more than half the votes!
Eras in Democracy
In a district where only the biggest party wins a rep, only two big parties thrive. So the voters get only two real candidates; that is a very limited choice.
A council majority sets policies (dark blue in picture) in a war of winner take all.
Typical Council Elected By Plurality Rule
It elects several reps from each voting district. It gives a group that earns, say 20% of the votes, 20% of the coulcil seats. Thus PR delivers fair shares of representation.
So the side with the most seats (blue and black) forms the ruling majority, which then enacts policies skewed to one side.
Typical Council Elected By Proportional Representation
Most voters in the winners' wide base of support don't want averaged or centrist policies. They want policies to unite the best ideas from all groups.
Ensemble Elected By Central And Proportional Rules
A “compromise policy” tries to negotiate rival plans. But contrary plans forced together often work poorly; and so does the average of rival plans.
A “balanced policy” unites compatible ideas from all sides. This process needs advocates for diverse ideas. And more than that, it needs powerful moderators.
Old tally rules tend to cause one-sided results and tragedies.
An ensemble is inclusive; yet it is centered and decisive.
So it can make an organization popular, yet stable and quick.
We'll see these qualities again in the best ways to set budgets and policies.
A Small Example
High taxes, great gov. services Low taxes, poor gov. services
Ms. K is the candidate nearest four voters.
L is nearest two and M is nearest three.
Candidates L and M split the voters on the right.
A mere plurality gives the winner a weak mandate.
That is the authority voters give to winners.
K is nearest four voters. L is nearest two. M is nearest three.
Two voters who supported L now vote for M.
Do votes that move count more than others? Yes, No.
This winner has the power of a majority mandate.
Only four “wasted votes” fail to elect anyone.
(Later, these voters will use a rule that asks,
“Where is our center?”
And a bigger group will use a rule that asks,
“Which trio best represents all the voters?”)
Candidate M wins the runoff.
This photo shows voters choosing positions across two issue dimensions: left to right plus up and down. A person's position on the first issue does not help us guess their position on an independent issue.
Which leaves more wasted votes, plurality or runoff? Which gives the winner a stronger electoral mandate?
Kay wins a plurality. Em wins a runoff.
How does it work? You rank your favorite as your first choice,
and rank backups as your second choice, third and so on.
Then your ballot goes to your first-rank candidate.
If no candidate gets a majority, the one with the fewest
ballots loses. Then there is another round of counting.
Here is an analogy: Each candidate puts out a box. A voter puts his ballot in his favorite candidate's box. The ballots are counted.
If the box gets a majority of the ballots, it wins. If not, the voter moves his ballot to another candidate's box. Or, he waits, hoping others will move their ballots to his favorite box.
To break that deadlock, we have a rule: If a round of counting ballots finds no winner, the box with the fewest votes is eliminated. Its ballots go to each voter's next (2nd) choice -- probably a candidate with similar views and more popularity.
These transfers make voters condense into large groups supporting strong candidates. Ballots are counted again to see if any candidate gets half of the current top ranks.
In practice, each voter ranks the candidates as 1st choice, 2nd choice, 3rd etc. Then election officials move ballots between boxes or a computer tallies them.
In South Korea's 1987 presidential election, two
progressives faced the aide to a military dictator.
The progressives got a majority of the votes but split
their supporters. So the conservative won under
a plurality vote-counting rule. These rules elect
whoever gets the most votes; 50% is not required.
The winner claimed a mandate to continue repressive policies. Years later he was convicted of treason in the tragic killing of pro-democracy demonstrators.
With Instant Runoff Voting, ballots for the weaker progressive could have transferred to help elect the stronger one.
The U.S. also has seen major elections in which two candidates on the left split their voters or two on the right split theirs. Sometimes this increased our national tragedies. (Can you name some split elections and their tragic results?)
From five factions to one majority.
In some places, people call this Rank Choice Voting, Preference Voting or the Alternative Vote.
IRV lets you vote for the candidate you really like. And even if that option loses, your vote isn't wasted; it goes to your next choice.
B wins 5 votes as J gets 4 in the top group.
A minority with 11 voters elects a majority, 2 reps. But if evenly spread out, they would elect none.
Now a majority gets two reps and a minority get one.
That is, 60% of the vote gets you 60% of the seats,
not all of them. And 10% of the vote gets you 10%
of the seats, not none of them. These are fair shares.
Those Chicago Republicans were usually moderates. So were Democratic reps from Republican strongholds. Even the biggest party in a district tended to elect reps who were more independent. They could work together and make state policies more moderate.
(The transferable-vote game shows one way to get PR — which is also called Fair Voting, Proportional Voting, Full Representation, or Fair Representation.
The number of women elected rose from 21% to 29%. The number of native Maoris elected rose from 7% to 16%, which is almost proportional to the Maori population. Voters also elected 3 Polynesian reps and 1 Asian rep.
New Zealand and Germany elect half of their MPs by list PR and half of them in single-winner districts. Their districts elect few women; but in the same elec¬tion, the PR lists elect three times more women.
In every one-seat district, a party's safest nominee is likely to be a member of the dominant sex, race, etc. That adds up to very poor representation of all others.
PR leads each party to nominate a balanced team of candidates to attract voters. This promotes women. A team may have class, ethnic and religious diversity. And that gives us diverse reps to approach for help.
This credible threat made some parties decide that job experience was not as important as gender balance. They dropped some experienced men to make more room for women on the party list. And they won. Now they are incumbents with experience, power and allies.
In a SMD, a landslide winner wastes surplus votes. But Fair Rep elects reps with equal numbers of votes. So any council majority really stands for most voters. That helps its policies match public opinion better.
If those urgent needs overwhelm us, we neglect the essential needs, the structural roots of our problems. We often get bad results from poor policies, due to poor representation, caused at the root by bad voting rules.
The countries with the best voting rules get the best quality of life, as measured in their international scores. So the people who want to raise the quality of their city or country all need to take action for better voting.
Public campaign funding in Maine and Arizona lets reps spend less time with rich sponsors and more with voters. One plan would gives each voter $50 of vouchers to donate. Such small, nameless donations or FS can cut corrupt paybacks.
One-seat districts let the campaign PACs pour floods of money into the few tossup districts and thus win most of the swing seats. PR has close races in many multi-seat districts, forcing the PACs to spread out their money into most districts.
Ballot access laws make it hard for minor parties to get nominees on the ballot. The two big parties make those laws largely because they fear spoiler candidates. Better voting rules such as IRV can calm that fear.
Sabbatical terms make the current rep run against a former rep returning from sabbatical. Voters get a real choice between two winners. Each has a record of what they did in office. Plurality rule would tend to make the current and former reps both lose by splitting their party. But these rank-voting rules do not split parties. A sabbatical might pay the rep to work with others from all parties on a service project, a bus tour and a rural retreat.
Initiative voters get more choices and power through ranked-choice ballots and better tallies. They should set the political rules and ratify the laws about lobbyists, PACs, campaign ads and salary for reps. But minority rights to ballots, reps and funds need constitutional protection from the majority of the day.
Proportional Representation distributes the council seats fairly.
Democratic rights fulfilled through history:
Voting for rich men, poor men, “colored” men, women.
Proportional Representation for large political minorities.
Fair-share spending by big groups of voters or reps.
Fair shares give minority voters some power.
Even in groups that lack competitive elections, some members compete over money to fund their projects. So some may connive to capture part of the budget. This injustice can push others to rebel or just leave. They have a right to fair shares of decision power.
Bad election rules are even worse at setting budgets: They're not 'cost aware,' and so increase tactical nominations and voting. A majority needs many candidates to elect several; but if votes split badly, they win less than their share.
Consensus would struggle to weigh dozens of desires, of varied cost and priority, from dozens of overlapping groups.
Many empty hands Fair Shares
The old way to set budgets blurs responsibility. Take deficit spending: Progressives may say too much is spent on big weapons and corporate subsidies; conservatives often blame the money spent on health, education and the environment. Every rep can claim, “I didn't spend too much.”
Protecting the environment is popular with both conservative and progressive voters. Reps don't dare attack it openly. So, to pay off some campaign gifts from corporate sponsors, reps slyly starve agencies that enforce environmental laws. Budget cuts have also starved OSHA, ATF and the auditors of corporate tax returns.
“Lower but constant funding is more productive than a roller-coaster budget that might average far more.” Alvin Trivelpiece, director, Oak Ridge National Laboratory
The Texas Super-Conducting Super Collider was a multi-billion dollar project in the 1980s. This effort to build the world's largest cyclotron was supported by a majority in Congress for a few years... then dropped. The only thing built was a “billion-dollar hole in the ground.”
Members might be more cautious about starting vast projects if they could not spend the opposition's share of the budget. And they should have the power to finish their projects with their own share.
The U.S. Congress let a single rep “earmark” funds for pet projects in her district. In 1994, the 4,000 earmarks cost us $23 billion. Ten years later, the 14,000 earmarks cost us $45 billion.
Earmarks let powerful reps take much more money to their districts than most reps do. Each rep voted yes or no to a huge “omnibus” bill. It held hundreds of earmarks, some good, some bad. This budget system made it hard to prove which reps are wasting money.
At their best, earmarks let a rep use federal money to fund vital local projects that only locals see the need and chance to do. But there is a better, more responsive and democratic way to select projects, Participatory Budgeting.
Participatory Budgeting is a big step up for democracy. It lets local meetings research, talk and vote on how to spend part of a city's budget. In South America, it spread from 1 city in 1990 to over 1000 today. The World Bank reports that the Participatory Budgeting or PB process tends to raise a city's health and education while reducing corruption.
For the last four years, a savvy alderman in Chicago gave his “discretionary fund” to the PB process. It was a popular success. But due to an old plurality rule, similar to bloc vote, more than half the votes were 'wasted': a majority of votes went to losers.
Even the winning votes were wildly unequal. A vote for the playground was worth $501. But a vote for the bike racks was worth only $31. That's too unfair; we can do better. We can give every voter the power to guide a fair share of money, with Proportional Voting: PV for PB.
Voting reform is hard because unfair rules have become entrenched by centuries of use. Because PB is still young, we have a rare opportunity to introduce better voting rules now — voting rules that are more expressive and more fair.
That is, 60% of the voters spend 60% of the money,
not all of it. A project needs grants from many
voters to show that it is a common good worthy of group funding.
So we let a voter fund only a fraction of a project.
How does it work? Like IRV: You rank your choices.
Then your money moves to help your top choices. And a tally of all ballots drops the least-funded project. This repeats until all projects still in the race are fully funded.
(The movable-vote game makes this process easy to grasp.)
Each proposal needs support
from a substantial group.
Every neighborhood and interest group controls its share of spending power; no one is shut out. This cuts the incentive for a group to dominate others. So it makes (hidden) empires less profitable.
If a plurality spends all the money, the last thing they buy adds little to their happiness. It is a low priority. But that money could buy the high-priority favorite of a large minority; making them happier.
In economic terms: The “social utility” of the money and goods tends to increase if we each allocate a share. Shares spread out opportunities and incentives too.
In political terms: Fair shares earn wide respect, as we each help big minorities to fund some projects. So our budget appeals to more people.
Each budget level of an item is like a project: To win, it needs to get a base number of votes.1 It gets a vote when a ballot pays a share of the cost up to that level or higher. cost / base = 1 share = 1 vote If more ballots share the cost, each of them pays less.
One at a time, the weak ones lose and the money moves. The item that gets the fewest votes for its current top level, loses that level. Any money you gave it flows to your highest rank that lacks your vote. This repeats until the remaining top level of each item is fully funded - by a strong base of support.
1) In FS, the proper name for a base of support is a “support requirement” for each budget level.
• If a level gets more than enough votes and money, a share of the surplus goes back to each donor, as in STV.
• The voting game shows how to give your favorite two votes and lower choices less than one.
My second choice lost; did it waste any of my power?
My third choice was so popular, I paid only 2% of it. Did I waste much power by voting for this sure winner? How many ballots shared this cost?
Fair shares can set the budgets of departments too.
Each “line item” starts with most of its past budget.2 A voter may write-in and rank higher budget levels for a department.
2) Each item could start with all of its past budget:
A voter ranks the ones he is most willing to cut, with his share of “negative dollars”. (A second poll could let voters try to restore and increase funding to their favorite items.)
Each agency starts with % of its current budget.*
A rep may refill only a limited share of each budget.
So it takes many reps to refill one, and more to raise it.
You repeatedly adjust your grants, causing and countering budget changes, until a timer stops the voting.
* To vote less than about % to basic services, such as
the police or public health, would be “stealing a free ride.”
BRV lets a majority reduce their grants to agency X. This undercuts a minority's grants to X. So, to maintain the total for X, the minority must give it bigger grants. Then the majority reduces theirs again, and this cycle repeats. With BRV, nobody apportions the budget as they sincerely want it. In contrast, the fair-share rule above gives all large groups positive power to fund their favorites.
Here is a second Pairwise test with the same voters.
K is nearest four voters. L is nearest five voters.
She has won majorities against each of her rivals. So her position is the “Condorcet winner”, the one policy judged to be best by every majority of voters.
Thus Pairwise picks a central chairperson or policy.
Is it likely to elect diverse reps? Yes, No.
L is nearest 6 voters; M is nearest 3.
The sports analogy is a “round-robin tournament.” A player has one contest against each rival. If she wins all of her tests, then she wins the tournament.
Option J tops option D if most voters rank J above D.
Each ballot's rank of J relative to D concerns us.
The numbers of first-rank votes do not.
If another rule picks a different winner our “round-robin tournament,” or Condorcet winner ranks higher on most ballots. So it wins a one-against-one majority over that other rule's winner.
(More merits of the Pairwise or “Condorcet” rule...)
Everyone helps choose our center.
The Pairwise winner is central and popular: Most centrist and progressive voters like it more than any conservative policy. At the same time, most centrist and conservative voters like it more than any progressive policy. All sides can join to beat narrowly-centrist policies.
This is an attractive service for consultants to offer clubs, co-ops, colleges and companies. It might become a popular reform. Even reps, who tend to oppose changing the election rules that gave them power, may favor legislative rules that reduce polarization and deadlock.
Conservative voters rank Bush [Major, Kohl] higher than Clinton. So to win a majority over Bush, Clinton must appeal to centrists and progressives.
In this Pairwise election of a moderator, a less controversial candidate might top each of these polarizing politicians. To pick a moderate, an election district needs diverse voters.
(A later page shows an interactive Pairwise tally table.)
The old plurality rule is the easiest to manipulate. (Borda and point voting are often susceptible too.) But the Pairwise winner, L, doesn't change in this case. Proportional Representation or (post-election) proxy votes avoid even the common bias due to housing patterns.
Now K has 3 votes. L has two. And M has four.
Voting rules that give fair shares of seats and spending also reduce the payoffs to those who bribe the biggest party. It can no longer seize more than its share of reps or money.
Or people may talk about all options at once but never clearly tell (vote) their second and third choices. So a few people pushing a single idea can appear to be the strongest group. And one person with a balanced solution but no eager supporters might drop it.
A yes-no process may let a committee report only two options for all members to choose between.
The best rules avoid all those problems by ranking the competing options on one ballot.
Voting rules affect our laws — and our views on life.
By making us give fair shares or winner take all,
voting shapes a way we treat each other and see our way of life.
Official rules model the goals for shared decisions. So those rules can affect the patterns used by workers, friends and neighbors.
These rules help make it safe and easy to cooperate. This favors people who tend to do it and leads others to do it more often.
The best tools help groups embrace diversity and freedom. So the group's size and resilience may increase.
|Happiness is strongly linked to good relationships. So a good way to raise happiness is to improve the tools between people.|
Why Take VotesGroups with little time and many issues or competing interests, often end a discussion by asking for votes not consensus. Their methods of discussion and of voting each affect the quality of their decisions and the group's morale.
The secret ballot can protect voters from many types of coercion.
The Condorcet policy can please most members more, because it won't favor a fringe opinion. It also does not need to favor the status quo, except bylaws.
Fair-share Spending can give fair shares of power. Inclusive yet fast, it doesn't let one member block action. It is co-operative decision making, not individual nor hierarchical, not consensual nor adversarial. Multi-winner rules are less about blocking rivals, more about attracting allies.
One set of policies sometimes cannot suit two groups with opposing values.
Moving to a better place is the surest way to get the policies you want.
This is often called “voting with your feet”.
That is practical when you have the freedom to move and diverse destinations to choose among. Such diversity is more likely when culture and technology give places economic independence through “local self-reliance”.
Even when you can't move to a better city or country, you may still avoid willful authoritarians. Build your democratic groups with fair egalitarians.
Democracy improves in eras such as The Enlightenment. Many people restrained blind faith, obedience and ideology. They expanded our knowledge of the universe and understanding of life through rational, skeptical, empirical thinking.
Benefits and Costs
Many people are excited to learn that voting does not have to mean “winner take all.”
The best voting rules strengthen the ballots for voters.

Give fair representation to all major groups. So the council enacts laws with real majorities.
The data make it clear: Advocates for education, health care, a clean environment and a clean government should all work for better voting rules. Donors should too.
If we are overwhelmed by urgent needs, we neglect the essentials, the structural roots of these problems. We continue to get bad public policies, due to bad representation, due to bad election laws.
Your work goes on giving to a school, club or town.
Election campaigns cost a lot all at once. If you win control, you can help all issues for two years.
Reform campaigns cost no more than elections. A win affects the whole council for many years. Your work keeps giving to a school, club or town.
Which is more stable and quick?
Help your college, co-op, club or congregation.
Does your car have an 1890 steering tiller or a new, power steering wheel? Does your organization have an 1890 voting rule or a new, centered and balanced rule?
Today's drivers need the skill to use power steering — but they don't need the math or logic to engineer it. Same with voters and voting rules.
Many groups adopt a standard book of parliamentary rules; then they amend it with their own “special rules of order”. So they own a modern vehicle for making their decisions more popular, stable and quick.

This website has sim games and handouts,
This text is © CC BY-SA 3.0, so edit it as you will and add your own slides for other topics. For example, U.S. voters need concise statements of the principles and benefits in non-partisan redistricting, as practiced in Iowa, and public campaign funding, as practiced in Arizona, Maine, or North Carolina.
You may want to skip some topics or change the wording to suit an audience. For legislators you might change “voter” to “rep” or “member” and you would do the opposite for a direct democracy.
Thanks to Steve Chessin for writing the original version of the “elevator pitch” for Proportional Representation. He, Terry Bouricius, and Zo Tobi each wrote quick pitches for Instant Runoff Voting which were the basis for the IRV slides above. Overall editors include Tree Bressen, Cheryl Hogue, John Richardson, and Rob Richie. Many others have contributed ideas and writing.
