What Worldwide Adoption Of Ranked-Choice Voting Would Do For Political Tribalism

Most people think political tribalism is a human nature problem. It's partly that. But it's also an engineering problem. The rules of the game shape the behavior of the players.

First-past-the-post (FPTP) voting creates specific psychological incentives:

- Binary thinking: With only one vote, you're pushed toward the most "viable" candidate in a two-way race. Third parties become spoilers. Nuance becomes liability. - Strategic voting: You don't vote for who you actually want. You vote against who you most fear. This poisons the relationship between citizens and their democracy. - Safe seats and gerrymandering: In FPTP systems, most districts are "safe" for one party. The real contest is the primary, where candidates compete to be the most extreme version of their tribe. - Negative campaigning: The most efficient way to win is to make the other candidate unacceptable. Tearing down is cheaper than building up. - Wasted votes: In any FPTP election, voters for losing candidates have zero representation. In some systems, a majority of voters are effectively unrepresented.

These aren't character flaws. They're predictable outputs of a specific system design. Change the design, change the output.

Instant Runoff Voting (IRV): The most common form. Voters rank candidates. If no one gets 50%+ of first-choice votes, the last-place candidate is eliminated and their voters' second choices are redistributed. Repeat until someone has a majority.

Single Transferable Vote (STV): Used for multi-seat districts. Voters rank candidates, and seats are filled based on a quota system with vote transfers. Ireland and Australia's Senate use this.

Condorcet methods: The winner is whoever would beat every other candidate in a head-to-head matchup. More theoretically elegant, less commonly implemented.

STAR Voting (Score Then Automatic Runoff): Voters score each candidate 0-5, the top two scorers enter an automatic runoff determined by who was preferred on more ballots. Gaining traction as an alternative to IRV.

Each system has different mathematical properties, but they share a core feature: voters express preferences beyond a single binary choice, and the winner must earn broad support rather than just plurality support.

The behavioral shifts under ranked-choice voting are documented, not theoretical:

Reduced negative campaigning: A 2014 Rutgers-Eagleton poll found that voters in ranked-choice cities reported less negative campaigning and more civil campaigns. A 2021 study of ranked-choice elections in the United States found a 30% reduction in negative campaigning compared to FPTP races.

Coalition campaigning: In ranked-choice systems, candidates frequently campaign together, asking voters to rank them first and an allied candidate second. This was visible in New York City's 2021 Democratic mayoral primary and in Australian federal elections routinely.

Broader appeal requirement: Candidates must appeal beyond their base to win second- and third-choice votes. This structurally rewards moderation, coalition-building, and attention to diverse constituencies.

Third-party viability: Voters can rank a third-party candidate first without fear of "wasting" their vote, since their vote transfers if that candidate is eliminated. This breaks the two-party stranglehold that produces polarization.

Candidate diversity: Research from RepresentWomen found that ranked-choice voting is correlated with increased representation of women and candidates of color. The mechanism: when campaigns are less adversarial, the barriers to entry for non-traditional candidates decrease.

Australia adopted preferential voting for its House of Representatives in 1918. Over a century of data provides the clearest picture of long-term effects:

- Australia has maintained a multiparty system with significant third-party representation. The Greens, Nationals, and independents hold meaningful seats. - Coalition politics is the norm. Governing requires building actual coalitions, not winner-take-all dominance. - While Australia is not free of political conflict, its public discourse is measurably less polarized than the U.S. or UK. Affective polarization (how much partisans dislike the other side) is significantly lower. - Voter turnout is high (compulsory voting helps, but the system's legitimacy also contributes to compliance). - Extremist parties struggle to gain traction because the preferential system requires broad appeal, not just passionate minority support.

Australia isn't a utopia. But it demonstrates that a different voting mechanism produces a fundamentally different political culture over time.

Ireland has used STV since 1922 for its Dail (parliament). Effects:

- Multi-party system with coalition governance as the norm. - TDs (members of parliament) must maintain personal constituency relationships because they compete with members of their own party for preference votes. This keeps politicians locally accountable. - Political violence, while present in Irish history for many reasons, has not been driven by the electoral system. The system has successfully integrated formerly militant political movements into democratic participation. - Irish political culture is notably less polarized than comparable FPTP democracies.

"It's too complicated." Voters rank candidates 1, 2, 3. Children do this when picking teams for kickball. The counting is complex; the voting is simple. In every jurisdiction that has adopted ranked-choice voting, the overwhelming majority of voters report finding it easy to use.

"It leads to confusing results." Any system that requires runoffs or coalition-building feels less clean than "most votes wins." But "most votes wins" also means a candidate with 35% support can win against two opponents who split 65%. That's not clean. That's distortive.

"It benefits centrists and moderates." It benefits candidates with broad appeal. Whether that's a centrist, a progressive with cross-party appeal, or a conservative who isn't alienating to non-conservatives depends on the electorate. The system doesn't pick ideology. It picks breadth of support.

"It won't fix polarization by itself." True. Media ecosystems, economic inequality, racial grievance, and cultural sorting all drive polarization. But voting systems are the structural foundation on which all those dynamics play out. Fix the foundation, and you change what's buildable on top of it.

Constitutional amendments or legislative reform in most countries. This is the primary barrier. Incumbent politicians in FPTP systems benefit from the current structure and resist change.

Voter education campaigns. Not because the system is complex, but because people are accustomed to the old system and need to understand the new one.

Technology upgrades for counting systems, though many jurisdictions already use electronic vote tabulation that can handle ranked ballots.

Civil society momentum. In the U.S., organizations like FairVote and the Ranked Choice Voting Resource Center are driving adoption city by city, state by state. Similar movements exist globally.

International demonstration effects. As more jurisdictions adopt ranked-choice voting and demonstrate reduced polarization, others will follow. Alaska and Maine are currently serving as demonstration projects for the rest of the U.S.

Imagine this: an election where you genuinely evaluate all candidates on their merits. Where you don't hold your nose and vote for the lesser evil. Where candidates visit your neighborhood even though it's not "their" territory. Where the winner has to acknowledge the legitimacy of the losers' concerns because those voters' second choices got them over the line.

That's not fantasy. That's Tuesday in Australia.

Now scale it globally. Every national election. Every local election. A species that designs its collective decision-making to reward cooperation rather than conflict. That rewards breadth rather than intensity. That gives every voter meaningful expression rather than a binary forced choice.

The technical change is minor. The cultural change is civilizational.

1. Rank Your Preferences: Think about the last election you voted in. If you could have ranked all candidates, how would your rankings have looked? What changes about your relationship to that election?

2. The Campaign Redesign: Pick a recent divisive election. Rewrite one candidate's campaign strategy assuming ranked-choice voting. What would they do differently?

3. The Tribal Audit: How much of your political identity is defined by who you're against rather than what you're for? What would shift if the system no longer rewarded that opposition?

4. The Conversation Test: Discuss ranked-choice voting with someone from a different political perspective. Focus on the mechanism, not the ideology. Notice where agreement is easier than expected.

5. The System Design Question: If you were designing a democratic system from scratch for a new country, what voting method would you choose? Why? What does your answer reveal about what you value in collective decision-making?
