R0050/2026-03-31-02/Q001/H1¶
Statement¶
At least one journalistic fact-checking framework includes all four structural features: hierarchical evidence quality scale, calibrated uncertainty language, structured bias assessment domains, and formal source reliability tiering.
Status¶
Current: Eliminated
Supporting Evidence¶
| Evidence | Summary |
|---|---|
| None | No evidence found supporting the presence of all four features in any single framework |
Contradicting Evidence¶
| Evidence | Summary |
|---|---|
| SRC01-E01 | IFCN principles are procedural commitments, not structural scoring systems |
| SRC02-E01 | PolitiFact's Truth-O-Meter rates claims, not evidence quality |
| SRC03-E01 | NewsGuard scores outlets on transparency/credibility, not individual evidence |
| SRC06-E01 | SPJ provides ethical principles without structured assessment tools |
Reasoning¶
Extensive search across all seven named frameworks and additional published methodologies found no single framework that integrates all four features. Each framework addresses verification through different mechanisms — editorial processes, ethical principles, or scoring systems — but none combine a formal evidence hierarchy, calibrated probability language, structured bias domains, and source reliability tiers into an integrated methodology.
Relationship to Other Hypotheses¶
H1 represents the strongest possible affirmative answer. Its elimination strengthens H2 (partial presence) as the most likely outcome, since individual elements do appear across frameworks.
