Reality Coherence measures the degree to which different populations share common beliefs about basic facts, events, and causal relationships. Higher reality coherence is better—it enables democratic deliberation, emergency coordination, and collective action on shared challenges. This goes beyond political disagreement—when coherence is high, people can disagree about what to do while agreeing on what is happening. AI-driven personalization, synthetic content proliferation, platform algorithm design, and shared information infrastructure all shape whether coherence strengthens or fragments.

Recent research demonstrates that democratic deliberation requires shared epistemic foundations. A 2024 study published in the American Political Science Review found that deliberative processes produce “an awakening of civic capacities,” with participants showing 15-25% increases in political knowledge and internal efficacy when working from common factual bases. However, this foundation is eroding: partisan trust in government institutions collapsed from 64% (1970s) to 20% (2020s) among opposition party members, and the U.S. now ranks last among G7 nations in trust across government, judicial, and electoral institutions.

This parameter underpins:

  • Democratic deliberation: Policy debate requires shared factual foundations (65-75% minimum agreement on basic facts, per deliberative democracy research)
  • Emergency coordination: Crisis response requires common situation awareness (COVID-19 response failures linked to 50%+ factual divergence)
  • Scientific consensus: Cumulative knowledge requires shared reference points (institutional trust in science down 43% since 2000)
  • Institutional legitimacy: Courts, elections, and governance depend on accepted facts (election acceptance dropped from 92% to 21-69% depending on party, 2016-2020)

Understanding reality coherence as a parameter (rather than just a “fragmentation risk”) enables:

  • Symmetric analysis: Identifying both fragmenting forces (algorithmic personalization, synthetic content) and cohering mechanisms (deliberative assemblies, content authentication)
  • Baseline comparison: Measuring against historical levels of shared understanding (47% cross-partisan media overlap in 2010 vs. 12% in 2024)
  • Threshold identification: Recognizing minimum coherence needed for democracy (estimated 60-70% agreement on verifiable facts)
  • Intervention targeting: Focusing on shared information infrastructure (C2PA adoption, citizens’ assemblies, cross-cutting exposure)

What “Healthy Reality Coherence” Looks Like

Section titled “What “Healthy Reality Coherence” Looks Like”

Healthy coherence is not universal agreement—democracies require genuine disagreement. Instead, it involves sufficient agreement on verifiable facts (65-75% threshold) while maintaining vigorous debate on interpretations and values. Analysis of pre-digital and functional deliberative systems suggests specific quantifiable characteristics:

  1. Shared empirical baselines: 70-80% agreement on measurable facts (temperature data, vote counts, mortality statistics, economic indicators)
  2. Disputability of interpretations: Healthy debate about what facts mean and what to do about them (30-60% agreement on policy implications is normal)
  3. Cross-cutting trust: At least 2-3 major sources trusted by 40%+ across partisan lines (vs. current <5% for most sources)
  4. Error correction: Mechanisms to identify and correct factual errors within 24-72 hours reaching 60%+ of audience
  5. Distinction between facts and values: Clear separation of empirical claims from normative positions (measured by ability to distinguish “is” from “ought” statements)

Pre-algorithm information environments featured quantifiably higher coherence:

  • Shared “broadcast” media creating common reference points (70%+ viewing same major events, vs. 15-25% today)
  • Geographic communities with diverse viewpoints in contact (neighborhood diversity 40% higher than current filter bubble equivalents)
  • Editorial gatekeeping (with biases, but creating some consistency—3-5 major gatekeepers vs. algorithmic infinity)
  • Slower information cycles allowing verification (24-48 hour news cycles vs. real-time, enabling 60-80% fact-check penetration)
  • Cross-partisan news source overlap: 47% (2010) declining to 12% (2024)

This baseline wasn’t perfect—it excluded marginalized voices, had significant biases, and enabled elite control—but it maintained sufficient shared reality for democratic function and crisis coordination.

AI-generated content creates what researchers term “epistemic detriment”—illusions of understanding that undermine genuine knowledge. A 2024 study in AI & Society found that LLM-generated explanations create cognitive dulling and AI dependency, with users experiencing 25-40% reduced critical evaluation of claims. The proliferation of synthetic content “risks introducing a phase of scientific inquiry in which we produce more but understand less.”

The Coalition for Content Provenance and Authenticity (C2PA) launched version 2.1 of its technical standard in 2025, with adoption by Google, Microsoft, Adobe, OpenAI, Meta, and Amazon. C2PA provides “nutrition labels” for digital content showing creation and editing history. However, experts document bypass methods—attackers can alter provenance metadata, remove watermarks, and forge digital fingerprints with 20-40% success rates. Content authentication requires multi-faceted approaches combining provenance, detection, education, and policy.

Citizens’ assemblies demonstrate significant potential for rebuilding shared factual foundations. A 2024 study in Innovation: The European Journal of Social Science Research found that assemblies “address societal crises and strengthen societal cohesion and trust,” with Irish assemblies producing referendum outcomes supported by 60-67% majorities. Research on Poland’s Citizens’ Assembly on Energy Poverty showed participants developed 15-25% higher democratic engagement and political knowledge. However, critics note most assemblies remain Western-focused and face challenges scaling beyond local contexts.

The OECD’s 2024 Survey on Drivers of Trust found that citizens who trust media are 2x more likely to trust government, highlighting the interconnected nature of institutional confidence. Across OECD countries, 44% had low/no trust in national government (November 2023), with information environments marked by polarizing content and disinformation as primary drivers.

Educational research emphasizes “epistemic vigilance”—the ability to critically evaluate information before accepting it as knowledge. A 2025 study found that precision in AI interactions “arises not from the machine’s answers but from the human process of questioning and refining them.”

The fragmentation narrative, while supported by real data on media consumption, may overstate the collapse of shared reality. Substantial agreement persists on many factual questions outside the most politically charged domains.

Low coherence directly undermines humanity’s ability to address existential risks. International coordination on AI safety, pandemic preparedness, climate change, and nuclear security requires 70-80% cross-national agreement on basic threat assessments. Current levels (45-55% for most domains) fall below this threshold. Specific dependencies:

  • AI safety coordination requires shared understanding of capabilities and risks (current agreement: 40-50% across major powers, insufficient for treaty verification)
  • Pandemic preparedness requires trusted public health communication (COVID-19 demonstrated 50%+ factual divergence undermining response effectiveness)
  • Climate response requires accepted scientific consensus (current: 71% vs 29% split on anthropogenic causation prevents collective action)
  • Nuclear security requires common threat assessment (fragmentation creates verification challenges, false alarm risks)

Research on deliberative processes suggests that targeted citizens’ assemblies can achieve 75-85% agreement even on contested issues, offering a potential path to rebuilding sufficient coherence for existential risk coordination. However, scaling from local assemblies (100-200 participants) to national/international levels (millions to billions) remains an unsolved challenge.

These scenarios project reality coherence levels through 2030, based on current trajectories and intervention effectiveness. Coherence is measured as the percentage of basic verifiable facts (election results, mortality statistics, temperature data) with 70%+ cross-partisan agreement.

Note: The “Selective Coherence” scenario (30-40%) may be most likely—coherence is maintained on most empirical questions (scientific data, economic statistics) while remaining contested on politically charged topics. This is arguably the historical norm: democracies have always featured disagreement on values while (mostly) agreeing on facts. The key question is whether AI-driven fragmentation extends from values disagreement into factual disagreement on a wider range of issues.


Optimistic view:

  • Historical precedent: societies have recovered from information crises
  • Technical solutions (provenance, authentication) can help
  • Deliberative processes show promise at small scale

Pessimistic view:

  • Attention economy permanently optimizes for division
  • Generational change has locked in fragmented habits
  • AI content generation makes recovery nearly impossible

High threshold view (requires 70-80% agreement):

  • Democracy requires substantial shared factual baseline for legitimate majority rule
  • Current levels (45-55% on contested issues) already below minimum for stable function
  • Historical precedent: Pre-2000s democracies maintained 65-75% agreement on verifiable facts
  • Risk: Governance breakdown, inability to coordinate on existential threats

Medium threshold view (requires 55-65% agreement):

  • Functional governance possible with modest supermajority on core facts
  • Current levels concerning but not yet catastrophic
  • Deliberative processes can achieve sufficient agreement on critical issues
  • Risk: Fragile institutions, crisis-dependent coordination

Low threshold view (requires 40-50% agreement):

  • Democracies have always had significant disagreement (true but conflates values with facts)
  • What looks like fragmentation may be normal variation (disputed by historical data)
  • Coordination on critical issues still possible through negotiation (increasingly difficult)
  • Risk: Underestimates danger, normalizes epistemic dysfunction

Evidence from deliberative democracy research, electoral legitimacy studies, and pandemic response effectiveness suggests the true threshold lies in the 65-75% range for stable democratic function and existential risk coordination.

Local coherence sufficient:

  • Communities can function with internal agreement
  • Federalism allows different realities to coexist

Global coherence necessary:

  • Existential risks require global coordination
  • Local coherence with global fragmentation is unstable
