Credibility Assessment at Scale

Scoring every source individually works when you have ten sources. When your collection pipeline processes two hundred sources daily, individual scoring becomes a bottleneck. Scaled credibility assessment uses pre-scored source registries, automated classification, and exception-based review. Sources that have been scored previously carry their established rating. New sources get an automated preliminary score based on their class, domain, and observable characteristics. Only sources that fall in ambiguous score ranges or that fail consistency checks get manual analyst review.

1. Pre-Scored Source Registry Maintain a registry of all sources your pipeline has encountered, with their current credibility scores and review dates. When a previously-scored source appears in new collection, apply its existing score without re-evaluation — unless the score has expired.
2. Automated Preliminary Scoring New sources receive an automated score based on observable characteristics: domain reputation, publication type, author credentials, historical accuracy (if available), and source class. The automated score is a starting point, not a final assessment.
3. Exception-Based Review Only sources that score in the ambiguous range (11-15) or that produce findings inconsistent with higher-tier sources get flagged for manual analyst review. This focuses human attention where it matters most — on the borderline cases that automated scoring cannot resolve.
