How the confidence score is calculated

This score does not claim absolute truth. It estimates how well-supported an article is, based on evidence, corroboration, and editorial quality.

Core Signals

Source trust

Publisher transparency, correction habits, and baseline reputation.

Citations, primary sources, documents, and title-to-body alignment.

How much the same event is independently supported by other coverage.

Signals like sensational framing, weak sourcing, or context loss.
