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.

By Discipline →By Modern Reference →By Velocity →

Why these 12 sources

Most sources score high on one dimension and middling on others. The fact-checking-grade tier requires BOTH: methodology-transparent rigor (Discipline ≥ 80) AND fast cross-citation in current writing (Velocity ≥ 80). When you're verifying a claim that's currently in dispute, these are the sources whose authority + recency BOTH compound.

How this list is ranked

Selection criterion: Filter: Discipline ≥ 80 AND Velocity ≥ 80; ranked by mean of those two scores. Every source on this page is hand-scored against the SourceScore methodology v0.1; click any name to see its full breakdown across the four dimensions. The list is regenerated automatically on every dataset update — no editorial promotion or reorder beyond the ranking signal above.
