How to read the evidence

This feature combines primary research with institutional background. Primary studies provide methods and measurements; agencies and research institutions explain established context. Neither should be treated as infallible. Dates, samples, calibrations and definitions determine how far a conclusion travels.

Barnakle keeps the specialist-review requirement open because a clear explanation can still miss a technical qualification. The source list lets reviewers check the original evidence, and the evidence boundary prevents an engaging headline from becoming a promise the research did not make.
