If something here is wrong, I would rather fix it visibly.
A correction fixes something that was wrong when it was written: a misreported study, a wrong figure, a broken or mismatched reference, a claim the evidence doesn’t fully support.
An update is different. The statement was reasonable when it was written, but new evidence has changed the picture. The page is revised, and the change is dated and points to the study behind it.
Every correction and update is logged below with the date, the page or chapter affected, what it said and what it says now. Typos and formatting fixes aren’t logged.
