Research	R0050 — Journalism and Other Truth-Seeking Disciplines
Run	2026-03-31
Query	Q001
Hypothesis	H2

Statement

No journalistic fact-checking framework includes any of the four formal structured elements (hierarchical evidence quality scale, calibrated uncertainty language, structured bias assessment domains, or formal source reliability tiering).

Status

Current: Eliminated

The evidence clearly shows that at least NewsGuard operates a formal, structured, weighted scoring system for source reliability. While none of the frameworks include all four elements, the claim that none includes any is contradicted by the evidence.

Supporting Evidence

Evidence	Summary
SRC03-E01	IFCN lacks all four elements
SRC04-E01	BBC guidelines are principle-based without formal structured scales
SRC05-E01	Verification Handbook emphasizes principles, not structured frameworks

Contradicting Evidence

Evidence	Summary
SRC02-E01	NewsGuard's 9-criterion 0-100 point system is a formal structured source reliability tiering tool
SRC01-E01	PolitiFact's Truth-O-Meter is a formal structured graduated scale

Reasoning

H2 is eliminated because it requires that no framework includes any of the four elements. NewsGuard's scoring system clearly satisfies the definition of formal source reliability tiering — it is structured, weighted, scored, and produces tiered ratings. PolitiFact's Truth-O-Meter is a structured graduated scale for claim accuracy. While neither is a perfect match for the intelligence/scientific analogue, they are undeniably formal and structured.

Relationship to Other Hypotheses

H2 is the strongest negative claim and is eliminated by the existence of NewsGuard and PolitiFact's structured systems. The evidence better supports H3 (informal/implicit analogues with some formal exceptions).
