Editorial policy
The rules we hold ourselves to, in public. They apply to every video, every article, every caption.
1 · Corrections
If the evidence changes or we get something wrong, we update the content and say so. Corrections are never silent: each one is dated and logged on the corrections page, with what changed and why. Videos that cannot be edited are corrected with the platform's correction tools and pinned notes.
2 · Retraction watch
We run a monthly scan for retractions and expressions of concern affecting studies we have cited. A retracted source is removed or replaced, and the affected claim is re-checked against the remaining evidence.
3 · Independence
Independent & unsponsored. No brand ties, no paid content, no product names — evidence only. The full independence statement is on the About page.
4 · Medical boundary
For professionals: our clinician-facing content is educational. It summarizes published research; it is not medical advice, not a treatment protocol, and not a substitute for clinical training, judgment, or the regulations that apply where you practice.
For patients: our public-facing content is general education, not medical advice. It cannot tell you what is right for you. Any decision about a procedure belongs in a consultation with your own doctor, who knows your history and can examine you. We do not answer individual medical questions — in comments or by message. If you have symptoms or concerns, please see a clinician.
5 · Sources and licenses
Claims are cited with full references and DOIs. Original pages or figures from a paper appear only where the license permits, with attribution; data from closed-access sources is re-drawn as our own charts. We state our coverage honestly: we say how much of the identifiable high-quality evidence we reviewed — we never claim to have read “all the literature.”
6 · Comments and questions
We read comments and we correct ourselves publicly when a peer-reviewed study says we should. What we don't do is answer individual medical questions — that wouldn't be safe or fair to you. Comments containing personal health details may be hidden to protect the commenter.
7 · Claim language by evidence level
The strength of our wording is tied to the strength of the evidence. Every on-screen number carries its citation and one of these levels:
| Evidence level | How we phrase it |
|---|---|
| META-ANALYSIS | “reduces X by ~N% (95% CI …)” — quantified, confident where the pooled data allows it |
| SYSTEMATIC REVIEW | “the reviewed evidence indicates …” — direction stated, spread acknowledged |
| RCT | “a randomized trial (n=…) found …” — single-trial result, named as such |
| OBSERVATIONAL | “is associated with …” — association, never causation |
| CASE SERIES | “has been reported in …” — signal only, no effect claims |
| NOT CONFIRMED IN HUMANS | “in laboratory studies only — not confirmed in humans” — always said plainly |
8 · Copyright & rights holders
Our content cites published research and, only where the license permits, displays original pages or figures; closed-access data is re-drawn as our own charts, with attribution. If you are an author, publisher, or other rights holder and believe any material here has been used beyond its license, misattributed, or otherwise used improperly, please contact us at [email protected]. Every notice is reviewed; where a concern is substantiated we will correct the attribution, replace the material, or remove it — and log the change on our corrections page.
