View Edit History
Every page on this site has a "View edit history" link at the bottom. You can see exactly what changed, when, and why. No hidden edits, no silent changes. The full edit history of every article is public at /changes.
How We Handle Submissions
- Every submission is reviewed against the cited evidence
- If the science supports a change, we update the page
- The edit shows up in version history with a link to your submission
- We don't delete conflicting evidence — if there's genuine scientific disagreement, we show both sides
- We credit contributors who improve our content
Open Source
