The science leads
We choose questions because they reveal something useful about how the body or mind works. Headlines and visuals should invite curiosity, but the evidence determines the explanation—not the other way around.
Evidence and uncertainty
We prefer primary research, systematic reviews, respected reference works and public scientific institutions. A single study is not treated as final proof. When findings are mixed, early or limited, the article should say so plainly.
Clear, human writing
Technical terms are used only when they improve understanding. We avoid inflated claims, unnecessary alarm, keyword repetition and language that turns ordinary biology into a medical diagnosis.
Updates, corrections and commercial influence
Meaningful updates receive an updated date. Factual mistakes are corrected under the Corrections Policy. If sponsored or commercially supported material is introduced in the future, it will be clearly labeled and will not be allowed to determine scientific conclusions.
