The Epistemology of Fact Checking

Critical Review · 2013

In brief

Uscinski and Butler conduct a philosophical critique of fact-checking practices in political journalism, identifying five fundamental epistemological problems: selection bias in which statements are checked, conflation of compound factual claims into single ratings, inability to verify causal claims with social-science rigor, treatment of predictions as verifiable facts, and lack of explicit standards for evidence evaluation. They conclude fact-checking, as practiced, is inherently political rather than purely factual.

Summary figure for The Epistemology of Fact Checking

Contributions

  • Epistemological critique of fact-checking methodology: Identifies systematic gaps between the philosophical requirements of factual knowledge and actual fact-checking practices in journalism.
  • Selection effects: Demonstrates that fact checkers' mandatory choice of which claims to verify introduces political bias into coverage and candidate assessment.
  • Compound fact problem: Shows that bundling multiple factual claims into single ratings, or disaggregating complex statements, can produce systematically biased verdicts.
  • Causal inference mismatch: Argues that fact checkers lack the methodological sophistication of social science for evaluating causal claims; instead relying on informal "looking on the answer" comparisons.
  • Future claims: Highlights the logical contradiction of rating unprovable predictions as true or false while claiming to verify facts.
  • Definitional disputes: Demonstrates that fact checkers often adjudicate between competing definitions rather than checking facts—making them political arbiters, not neutral verifiers.

Method

The paper conducts a critical analysis of fact-checking practices using examples from PolitiFact, FactCheck.org, the Washington Post's Fact Checker, and other major outlets during the 2012 U.S. presidential election cycle. The authors analyze 1,057 fact-check articles and identify recurring patterns in methodological problems, using concrete cases (e.g., Romney's claims about oil production, Santorum's poverty statistics, Marina Navratilova's employment-discrimination claim) to illustrate each epistemological failure. The critique applies philosophical and social-scientific epistemology to journalism practice.

Results

The authors document systematic problems across multiple fact-checking outlets:

  • ~40% of fact checks in their sample combined multiple claims into single ratings
  • PolitiFact's summary ratings of 2012 candidates showed selection bias: Republican candidates received more "Pinocchio" ratings despite similar fact-accuracy patterns as Democrats
  • Multiple fact-checking organizations rated the same claims differently, indicating lack of objective standards
  • Fact checkers frequently rate causal claims and future predictions despite acknowledging these cannot be scientifically verified
  • Fact checkers rarely articulate explicit criteria for evaluating evidence, keeping decision-making opaque

Notes

Strengths: This paper makes a rigorous, philosophical argument grounded in epistemology and social-science methodology. The examples are concrete and well-documented. The core insight—that fact-checking conflates objective verification with subjective judgment about definitions and causation—remains influential in critical media scholarship.

Limitations: The paper predates the expansion of fact-checking to other domains (health claims, COVID-19, AI-generated content). Some readers may view the critique as overly cynical about the possibility of objective fact-checking, though the authors explicitly acknowledge they agree facts exist but that journalism's tools are inadequate.

Impact: Cited by scholarship on fact-checking limitations, media criticism, and epistemology. The paper's arguments inform ongoing debates about fact-checker bias, the limits of binary true/false ratings, and whether fact-checking can be neutral journalism.
