Same list, different signal

The composite SourceScore Index averages all three sub-scores. View this list re-sorted by ONE sub-score for a precision lens — different leader, different ranking, different deltas.

Why these 15 sources

Most A-tier composite sources have one dimension carrying the weight. The triple-crown set requires every dimension to clear the A bar independently — no compensation, no compromise. These are the safest citations across any context: rigorous evidence-citation, modern open-data infrastructure, AND high tier-1 citation velocity. The default first-choice tier.
