What we got wrong, and when we fixed it.
A publication that rates its own evidence has to be willing to publish its mistakes. This page explains how we handle corrections and records the substantive ones.
The correction policy
What we treat as a correction
A correction is any change that alters what a page tells you: a factual error, a misread source, an evidence rating that was set too high or too low, a recommendation that no longer follows from the research, or a limitation we should have listed and did not.
Fixing a typo, tightening a sentence, or updating a link that moved is not a correction. Those happen continuously and are not logged, because logging them would bury the changes that matter.
How a correction appears
The page itself is fixed first. The corrected page then carries a note describing what changed and when, and the change is added to the log below with a link to the affected page.
We do not delete the record of a mistake. If a claim was wrong, the fact that we published it is part of what you need in order to judge how much to trust the rest.
Where a correction changes an evidence rating, the reasoning is recorded alongside it — a rating that moves without an explanation is not much better than one that was wrong.
How to report one
Tell us which page, which claim, and what you think is wrong with it. A link to a source is enormously helpful but not required — "this does not match what I have read" is a legitimate report and we will go and check.
We read everything sent to us. We will not always agree, and where we do not, we will say why rather than going quiet.
Correction log
Substantive corrections appear here, newest first, each linked to the page it affected.
No corrections recorded yet
This is not a claim to be error-free. The site is new and few pages have published, so there has been little to correct. Entries will appear here as they occur.
Found an error?
Send us the page and the claim. Corrections are the part of the editorial process readers can actually see.
