Query: Does any journalistic fact-checking framework include a hierarchical evidence quality scale, calibrated uncertainty language, structured bias assessment domains, or formal source reliability tiering?
BLUF: No journalistic framework includes all four elements. NewsGuard has formal source reliability tiering (9-criterion 0-100 scoring), and PolitiFact has a graduated claim accuracy scale, but no framework includes calibrated uncertainty language or structured bias assessment domains. Journalism overwhelmingly relies on principle-based editorial judgment rather than formalized evaluation frameworks.
Answer: H3 (Informal analogues predominate) · Confidence: High
