Test any news or research source against a subject you already understand in depth. Errors in that familiar area reveal how cautiously its claims should be treated elsewhere. If a source performs poorly, seek someone with demonstrated qualifications and practical experience in the disputed field. Economics provides the example: specialist research is more reliable than general television commentary. The same method helps students evaluate secondary accounts before relying on them for unfamiliar history.
