Are Political Divisions Becoming More Intense Because of Genuine Disagreements or Because of How Disagreements Are Communicated?

Political divisions are becoming more intense because of both genuine disagreements and the way those disagreements are communicated. However, these two forces do not contribute equally to every form of polarization.

Real disagreements over immigration, inequality, religion, national identity, climate policy, race, gender, security and the role of government provide the substance of political conflict. Communication systems then select, simplify, personalize and emotionally intensify those disagreements. They can transform a difficult policy debate into a moral struggle between supposedly virtuous citizens and dangerous enemies.

The distinction is crucial. People may genuinely disagree about how much immigration a country should permit, how wealth should be redistributed or how religious freedom should be balanced against other rights. Those disagreements cannot be solved merely by encouraging people to speak more politely. They involve competing interests and values.

Yet the intensity of contemporary hostility often exceeds the actual distance between ordinary citizens’ policy preferences. Political leaders, partisan media and digital platforms frequently present the most extreme voices as representative of entire political groups. Citizens consequently react not only to what their opponents really believe, but also to distorted images of what they believe.

The best conclusion is that genuine disagreements create political divisions, but communication increasingly determines whether those divisions remain manageable or become socially destructive.

Genuine Disagreements Are Real

It would be a mistake to explain polarization entirely as a communication problem. Democracies contain substantive conflicts that cannot be resolved through better language alone.

Economic groups have different interests. Workers may demand higher wages and stronger labour protections, while employers may emphasize flexibility and business costs. Property owners and renters may have different preferences regarding housing policy. Wealthier citizens and lower-income citizens may disagree about taxation and redistribution.

Cultural and religious disagreements can be even more difficult. Citizens may hold incompatible beliefs about abortion, marriage, education, gender, religious authority or national traditions. In immigration debates, one group may emphasize humanitarian responsibility and economic opportunity, while another emphasizes border control, public-service capacity and cultural integration.

These disagreements are not necessarily based on ignorance or manipulation. People can examine the same evidence and reach different conclusions because they prioritize different values.

Cross-national experimental evidence demonstrates that policy disputes themselves can increase distrust. A ten-country study found that exposure to both economic and cultural disagreements produced greater distrust of opposing partisans. Immigration was an especially significant cultural driver in the experiment. (Cambridge University Press & Assessment)

This means that political communication does not invent every division. Some issues genuinely separate citizens. When an election could determine access to health care, taxation, reproductive rights, religious freedom or immigration status, people have rational reasons to care intensely about the outcome.

Calls for moderation can therefore become misleading when they treat every conflict as a misunderstanding. A marginalized community demanding equal treatment may not simply need a more respectful conversation with those defending the status quo. A worker facing economic displacement may have a material grievance that cannot be solved by media literacy.

A less polarized tone cannot substitute for substantive political reform.

Policy Disagreement Is Not the Same as Social Hostility

Although genuine disagreement matters, ideological distance and emotional hostility are not identical.

Political scientists often distinguish between issue polarization and affective polarization. Issue polarization concerns how far apart citizens or parties are on policy. Affective polarization concerns how strongly political groups dislike, distrust or morally condemn one another.

Two citizens may disagree substantially about taxation while still regarding each other as reasonable and legitimate. Conversely, they may hold relatively similar policy views while expressing intense hostility because they identify with opposing parties.

This distinction helps explain why some political arguments feel more extreme than the underlying policy differences justify. Partisan identity can become socially important in its own right. People may defend their political side because it represents their community, religion, region or cultural identity—not because they agree with every item in the party programme.

Research models suggest that party-platform divergence and affective hostility can reinforce each other. As citizens become more emotionally attached to their political groups, parties have incentives to adopt more sharply differentiated positions. As parties move farther apart, citizens receive stronger signals that the opposing side is threatening. (Cambridge University Press & Assessment)

Communication is central to this cycle because citizens rarely study every policy directly. They rely on politicians, journalists, influencers, friends and algorithmically selected content to explain what each side represents.

The political conflict people experience is therefore partly about real policy and partly about the stories attached to that policy.

Communication Turns Policy Choices Into Identity Threats

The wording used to describe a disagreement can determine whether citizens interpret it as a technical problem or an existential danger.

Consider immigration. One political actor may describe the issue as a question of labour-market needs, asylum procedures and administrative capacity. Another may describe it as an “invasion” intended to erase the nation. A third may argue that any restriction is evidence of hatred toward foreigners.

The policy disagreement is real, but the language determines its emotional meaning.

Similar patterns appear across many issues:

• Taxation becomes a conflict between “productive citizens” and “parasites.”

• Welfare policy becomes a struggle between “compassion” and “dependency.”

• Climate regulation becomes either planetary survival or an elite attack on ordinary livelihoods.

• Religious freedom becomes either protection from state control or permission to discriminate.

• Policing becomes either the defence of civilization or an instrument of systemic oppression.

These frames contain moral judgments about the people involved. Once an issue is moralized, compromise becomes difficult because negotiation can appear equivalent to cooperating with injustice.

Modern measures of affective polarization increasingly examine not only dislike but also othering, aversion and moralization. These dimensions capture the tendency to view political opponents as fundamentally alien, emotionally repulsive or morally corrupt. They are also associated with greater tolerance for antidemocratic conduct and political violence. (Cambridge University Press & Assessment)

Communication therefore does more than describe disagreement. It tells citizens what the disagreement reveals about the character and legitimacy of the opposing group.

Political Leaders Establish the Tone of Conflict

Political leaders play an especially important role because supporters often take cues from trusted elites.

A leader can argue that an opposing party’s policies are harmful while acknowledging that its voters remain legitimate citizens. Alternatively, the leader can claim that opponents are traitors, criminals or enemies secretly working to destroy the nation.

The underlying policy dispute may be identical, but the democratic consequences differ sharply.

Respectful communication from politicians is not merely symbolic. A preregistered experiment involving approximately 2,000 citizens found that positive or respectful statements by politicians about their opponents could reduce affective polarization among members of the public. (Cambridge University Press & Assessment)

This suggests that elite rhetoric can move political attitudes in both directions. If respectful signals reduce hostility, repeated insults and accusations are likely to reinforce the belief that opponents deserve contempt.

Leaders also influence which disagreements dominate public attention. A society may face dozens of policy challenges, but political actors select the issues most useful for mobilization. They may elevate a relatively narrow controversy into a test of national survival because fear increases loyalty and turnout.

Political communication becomes particularly dangerous when leaders exaggerate the beliefs of the opposing side. Citizens may be told that most of their opponents support violence, reject democracy or want to eliminate their way of life.

Research has found that people can substantially misperceive the democratic commitments of opposing partisans. These inaccurate beliefs can themselves contribute to tolerance for undemocratic behaviour: people become willing to violate democratic rules because they incorrectly believe the other side has already abandoned them. (Nature)

The result is defensive escalation. Each side becomes more extreme partly because it assumes the other side is even more extreme.

Social Media Rewards Conflict-Oriented Communication

Digital platforms did not create political disagreement, but they have changed which forms of political communication are rewarded.

Social-media systems measure engagement through clicks, comments, reactions, viewing time and shares. Content that produces anger or moral outrage can perform particularly well because emotionally activated users are more likely to interact.

A major study of political social-media content found that posts attacking or referring negatively to political out-groups were substantially more likely to be shared than posts focused only on the speaker’s own group. (PNAS)

This creates a structural incentive. Politicians, activists and media organizations learn that criticizing the opposition often attracts more attention than explaining policy. Even actors who begin with moderate intentions may adopt harsher communication because the platforms make outrage more visible.

The problem is not simply that citizens are placed inside echo chambers. It is also that political communication becomes performative. Users gain recognition within their communities by demonstrating hostility toward the opposing side.

Political identity is displayed through ridicule, slogans, edited video clips and moral denunciations. The objective shifts from persuading opponents to impressing allies.

Experimental research has found that partisan echo chambers can increase both policy polarization and affective polarization compared with politically mixed discussion groups. (Cambridge University Press & Assessment) This suggests that communication environments can alter not only feelings toward opponents but also the positions people adopt.

However, the solution is not as simple as exposing everyone to opposing content. A well-known field experiment found that social-media exposure to opposing political views could sometimes increase polarization rather than reduce it. (PNAS)

People do not automatically respond to disagreement with openness. When opposing views are presented aggressively, without trust or outside a meaningful relationship, users may become defensive and more committed to their original identities.

Communication quality matters as much as communication diversity.

Algorithms Shape the Emotional Environment

Algorithms influence polarization by deciding what receives prominence. They do not need to generate political hostility directly. They can amplify content containing hostility because that content produces measurable engagement.

This is important because algorithms operate repeatedly. A single inflammatory post may have little long-term effect, but continuous exposure can shape a user’s perception of the political environment. If a person repeatedly sees examples of opponents behaving irrationally or aggressively, that behaviour may begin to seem typical.

The user is not simply learning about individual events. The user is developing a model of what the entire opposing group is like.

A 2025 field experiment showed that reranking social-media content according to partisan animosity and antidemocratic attitudes affected users’ levels of affective polarization. Greater exposure to such content was associated with colder feelings toward political opponents, while reducing its ranking produced movement in the opposite direction. (Science)

This finding demonstrates that polarization is not determined solely by what citizens already believe. The design of the information environment can influence how frequently hostile interpretations are reinforced.

Technology is therefore an amplifier, but an amplifier can significantly change political outcomes. A disagreement communicated occasionally in measured language is different from the same disagreement delivered repeatedly through personalized messages designed to provoke anger.

Traditional Media Can Also Intensify Division

The polarizing effects of communication are not limited to social media.

Television, radio, newspapers and political talk programmes may depend on conflict for audience attention. Producers often select guests who will generate confrontation. Nuanced participants may receive less airtime because complicated explanations are less dramatic than certainty and accusation.

This can produce a distorted picture of public opinion. The most provocative representatives of each side become the visible face of the entire group.

Media formats also encourage false binaries. Complex questions are reduced to two opposing positions, even when public opinion contains many intermediate or mixed views. Citizens are encouraged to choose a camp before they have examined the details.

Partisan media can deepen loyalty by presenting every event as further proof of an existing narrative. A government success is ignored or reframed as deception by opposition media. A government failure is minimized or blamed entirely on hostile institutions by supportive media.

Nevertheless, exposure to partisan media does not mean that audiences are easily persuaded on every issue. Experimental research during contentious election periods indicates that citizens can be resistant to competing media narratives, especially when their partisan identities are already strong. (PNAS)

Communication may therefore reinforce and organize existing attitudes more often than it creates entirely new beliefs.

Misrepresentation Is Often More Polarizing Than Disagreement

One of the most damaging communication patterns is the use of extreme examples to represent an entire political group.

Every large movement contains unreasonable people. Digital media makes it possible to locate an offensive statement by an obscure activist and distribute it nationally or globally. Opposing commentators then present the statement as evidence of what millions of people secretly believe.

This process creates “false typicality.” Citizens correctly observe that an extreme statement exists but incorrectly conclude that it represents the average opponent.

The opposing side usually responds by highlighting its rival’s worst representatives. Both communities then compare their own ordinary members with the other side’s most radical members.

Because people understand the diversity within their own group, they interpret their side’s extremists as exceptions. Because they encounter the opposing group primarily through selected media examples, they interpret its extremists as representative.

Political communication consequently widens perceived disagreement even when actual policy differences remain stable.

This explains why correcting misperceptions can reduce some forms of polarization. In the Strengthening Democracy Challenge, a large megastudy testing 25 interventions found that different techniques addressed different dimensions of political conflict. Humanizing opponents helped reduce partisan animosity, while correcting inaccurate beliefs about opponents’ democratic attitudes was more relevant to reducing support for undemocratic practices. (Science)

The distinction matters. Citizens may dislike opponents because they have been dehumanized, fear them because their views have been misrepresented, or disagree with them because of genuine policy conflict. Each problem requires a different response.

Better Communication Cannot Eliminate Real Conflict

Although communication is a major intensifier, it would be naive to believe that political divisions can be solved through respectful language alone.

People may communicate perfectly clearly and still disagree about the distribution of wealth, the legal status of abortion, the recognition of minority rights or the use of military force. Some political decisions create real winners and losers.

Dialogue may improve mutual understanding without producing agreement.

Research on cross-partisan conversations supports this caution. Such conversations can reduce affective polarization, but the results depend on the topic, structure and conditions of the interaction. Some subjects are easier to discuss constructively than others. (Science)

Communication reforms must therefore be paired with institutional and policy changes. A community experiencing discrimination needs enforceable protections, not merely a more civil debate. Citizens affected by unemployment need economic opportunities, not just messages encouraging national unity.

Better communication helps people manage conflict. It does not remove the underlying interests and values that create conflict.

The Most Important Distinction: Disagreement Versus Delegitimization

The central democratic problem is not the existence of genuine disagreement. It is the communication of disagreement as proof that opponents have no legitimate place in the political community.

Healthy democratic communication says:

“We believe your proposal is wrong, and we will organize to defeat it.”

Destructive polarized communication says:

“Your support for that proposal proves that you are evil, disloyal and unworthy of political rights.”

The first statement leaves open the possibility of future elections, negotiation and coexistence. The second converts political competition into a struggle for permanent exclusion.

When delegitimization becomes widespread, citizens may support censorship, selective law enforcement or electoral manipulation because ordinary democratic rules appear inadequate against an allegedly existential enemy.

Political language becomes a security mechanism: each side convinces itself that violating democratic norms is necessary for self-defence.

Political divisions are becoming more intense because genuine disagreements and communication practices reinforce one another.

Real conflicts over economics, identity, religion, immigration, rights and political authority provide the foundation of polarization. These disagreements cannot be dismissed as media inventions. Citizens often have legitimate reasons to support different policies.

However, communication determines how those disagreements are understood. Political rhetoric can frame opponents as fellow citizens with competing priorities or as enemies seeking national destruction. Media can provide context or select the most inflammatory examples. Algorithms can expose users to diverse information or repeatedly reward hostility. Social platforms can facilitate deliberation or turn political identity into a performance of out-group contempt.

The evidence suggests that communication is especially important in explaining why political disagreement becomes emotionally intense. It magnifies perceived differences, encourages misrepresentation and transforms policy choices into judgments about personal morality and national belonging.

The strongest verdict is therefore this: genuine disagreements create the fault lines, but contemporary communication systems increase the pressure along those fault lines.

A democracy cannot eliminate disagreement without eliminating political freedom. It can, however, change how disagreement is communicated. Leaders can criticize policies without dehumanizing voters. Media organizations can stop treating extremists as representatives of entire communities. Platforms can reduce the automatic amplification of out-group hostility. Citizens can be exposed to accurate information about what opponents actually believe.

The objective should not be to make politics emotionless. Many political questions involve justice, dignity and survival and will understandably generate strong feelings.

The objective is to preserve a distinction between opposition and enmity.

Political divisions become dangerous not when citizens disagree strongly, but when communication persuades them that disagreement makes coexistence impossible.
