Corrections
What this site got wrong, when it changed, and how to tell me.
Everything here is written by one person, and some of it will be wrong. Not the opinions, which you can take or leave, but the facts: a number that moved, a rule that changed, a source that turned out to say something other than what I said it said.
When that happens I would rather you find it here than find it by acting on it.
How a correction works
When I fix something factual, the fix does not quietly replace the old text. The page keeps a dated note saying what it used to say and why it changed. Those notes live in the footnotes, next to the source they belong to, so you can check the correction against the evidence in the same place.
The reason for that is narrow and practical. A number changed silently looks identical to a number that was always right, and a later reader has no way to tell the difference. Neither do I, six months on.
This page is the index of those notes. The record itself always stays on the page it belongs to.
What counts
A correction is a factual change: a figure, a date, a requirement, a claim about what an institution does, a source that does not support what I used it for.
Rewriting a paragraph to read better is not a correction. Adding a section is not a correction. Changing my mind about advice is not a correction either, though if I reverse something substantial I will say so on the page where I said it.
The bar is whether a reader who acted on the old version would have been misled.
Before launch
This log starts the day the site went public. Before that I was drafting, and the ordinary business of drafting is that things are wrong until they are right.
That work is not hidden. The pages carry their own dated notes from well before launch, because I was already keeping them, and you can read those on the pages themselves. What this page does not do is present a draft's revision history as though it were a published record. Those are different things and only one of them is about you.
Telling me
If something here is wrong, write to [email protected].
You do not need to be sure, and you do not need to be polite about it. If you think a number is off, saying so is more useful than being right about it. I would rather check ten things that turn out to be fine than leave the one that is not.
If you turn out to be right, the fix goes on the page with the date, and it appears here.
