Site notes
Why our grades will change — and why that is the feature
4 min read ·
Most health content is written once and decays quietly. This site is built the opposite way: grades are not written at all — they are recomputed from the underlying study records every time a page is built. When the evidence moves, the site moves, and this feed is where we explain each move.
How a grade gets made
Every claim on this site has study records behind it: design, sample size, what was measured, which direction it pointed, retraction status. A fixed rubric — published in full on the methodology page — turns those facts into a grade. No human types 'moderate' into a box, which means no human can quietly leave a stale 'moderate' in place after a contradicting trial reports.
The rubric has hard rules worth knowing: no human-evidence grade without human studies, biomarker-only evidence is capped below strong, and the top grade requires independent replication. Animal lifespan results never support a human lifespan claim, however striking they are.
What to expect from this feed
Three kinds of posts. Evidence briefs, when a trial worth knowing about reports. Hype checks, when a claim goes viral and deserves a look at its actual record. And site notes like this one, when we change how the site itself works. Every post links into the graded evidence pages, because the point of the feed is not commentary — it is keeping you at the same distance from the literature that we keep ourselves.
