How we grade evidence
Every claim in the knowledge bank carries a grade from A to D. The grade describes the strength of the evidence — not how popular the claim is, and not how confident it sounds.
- Consistent evidence
Consistent meta-analyses, systematic reviews or position stands in humans. Several strong lines of research point the same way.
- Leaning evidence
Single randomized trials, or mixed evidence that clearly leans one way. Good enough to act on, held loosely.
- Limited evidence
Observational data, mechanistic reasoning or expert consensus. A plausible signal — not proof in humans.
- Insufficient evidence
Insufficient or contradictory research. The honest grade when the answer is: we don't know yet.
“We don't know” is an allowed answer
An instrument that always has an answer is a bad instrument. Where the research is thin or contradictory, we say so and grade it D rather than rounding a guess up to a fact. A grade can move in both directions as new research lands.
The process
- Every claim cites at least one appropriate peer-reviewed or authoritative source — position stands, meta-analyses, systematic reviews or peer-reviewed trials, with a working link. No screenshots, no hearsay.
- Every claim carries a visible “last reviewed” date and is re-checked against the research on a rolling schedule — at least yearly, sooner when significant new evidence lands.
- Changes are open: when a grade or a conclusion changes, the page changes openly — we don't quietly rewrite history.
