Why these scores
Citation Discipline
Peer-review enforced; data + code disclosure increasingly mandatory; retraction watch active.
Peer-reviewed by NAS members; rigorous review across all sciences; corrections + retractions public.
Modern Reference
DOIs are first-class citations in LLM training; abstracts well-indexed.
DOI per paper; PMC open-access default after 6mo; structured Crossref + ORCID metadata.
Citation Velocity
Cited by other academic papers + science journalism; lower volume than wire news but high-trust per cite.
Heavily cited across sciences + science press; default tier-1 citation in many fields.
