The source index

Every claim should leave a trail.

Here is the trail: every primary source cited on AI Solved X, the databases we scout, and the rules that keep a promising headline from becoming a misleading one.

01.

Discovery is not evidence.

Press releases, news coverage, newsletters, and social posts can point us toward a story. They cannot carry the claim by themselves.

02.

Primary beats popular.

We link the paper, registry, public dataset, technical report, or official evaluation that readers can inspect directly.

03.

Limits travel with the result.

Study design, sample, setting, conflicts, missing data, and real-world distance stay attached to every conclusion.

Where we look first

Ground truth before buzz.

This is a working map, not a claim that every record inside these systems is correct. Each candidate still has to survive our evidence score and independent fact check.

Mathematics and theoretical computing

We distinguish a proof from a conjecture, a finite computation from a universal result, and a public preprint from work that has completed expert review.

arXiv Mathematics ↗Public preprints, version histories, and author-submitted proofs
AMS MathSciNet ↗Reviewed mathematical literature and bibliographic records
Clay Mathematics Institute ↗Official status and descriptions of the Millennium Prize Problems
zbMATH Open ↗Open reviews and publication records across mathematics

Health and clinical evidence

We start with the published paper, then check trial registration and outcomes when human health claims are involved.

PubMed ↗Biomedical papers and publication records
ClinicalTrials.gov ↗Trial registrations, protocols, and reported results
WHO ICTRP ↗Clinical-trial records from registries around the world
CDC Data ↗Public-health surveillance and official datasets

Research records and reproducibility

These sources help us find early work, verify citations, and locate the code or data behind a claim. A preprint is a lead, not proof.

arXiv ↗Early research signals before peer review
Crossref ↗DOIs, publication metadata, and citation verification
Zenodo ↗Citable research datasets, software, and supporting files
OSF ↗Study materials, preregistrations, data, and analysis plans

Climate, Earth, and infrastructure

For forecasts, hazards, water, weather, and environmental claims, we look for observations and operational data—not a screenshot of a model demo.

NOAA NCEI ↗Weather, climate, ocean, coastal, and geophysical archives
NASA Earthdata ↗Satellite and Earth-observation datasets
USGS Data ↗Water, geology, hazards, ecosystems, and mapping data
Data.gov ↗U.S. government datasets across public services

Energy, transport, and engineering

We favor public test data, technical reports, standards work, and field results over product announcements.

DOE OSTI ↗Energy, computing, physics, and engineering research results
NHTSA Data ↗Vehicle safety tests, recalls, investigations, and crash data
NIST Data ↗Measurement science, standards, benchmarks, and reference data
NASA Science Data ↗Open scientific data across NASA research programs
