Methodology
The Press Credibility Index (PCI)
Our credibility score — displayed on every article — summarizes the estimated reliability of the information on a 0–100 scale. It combines independent source coverage, source quality, claim convergence, traceability, recency and neutrality.
Weighted criteria
Independent source count
Single-source stories are penalized; multi-source coverage receives a stronger base score.
Source quality
Each source has a trust score derived from editorial reputation, source type and historic reliability.
Source diversity
The system checks whether evidence comes from distinct outlets and domains rather than repeated copies.
Primary-source bonus
High-trust outlets and primary/agency-grade sources add confidence when they are present.
Convergence across claims
Extracted claims are compared across sources. Supporting or refining claims increase the score; contradictions reduce it.
Traceability
Claims with evidence quotes and direct URLs score higher than unsourced assertions.
Freshness
Recent reporting receives a small boost; older material is discounted.
Neutrality
Sensationalist phrasing and unsupported loaded language are penalized.
Penalties
Contradictions
Up to -25 points when sources or extracted claims materially contradict each other.
Sensationalism
Up to -10 points for clickbait wording, exaggerated framing or unsupported dramatic terms.
Credibility levels
Strong source quality and corroboration.
Generally reliable but some evidence may be incomplete.
Publishable only with caution and visible sourcing.
Not eligible for publication.
Transparency
Article pages expose the main sources and the scoring evidence used by the PCI. The score is an indicator, not a verdict: reliable outlets can publish errors, and smaller sources can publish accurate information.
