Errata
and who caught them
Every correction made to work published here, newest first, with the name of whoever found it and whether it changed a finding or only the prose.
Nothing has been corrected yet
That is a statement about this page's age, not about the work. Ten instruments are published here, nineteen of their pre-registered checks failed, and no outside reader has yet found an error in what survived. The honest reading is that not many people have looked.
This page existing empty is the point. Elsewhere the site promises that a correction means a new version with a visible supersession trail. Until this page, that was a promise with nothing to inspect — you could not tell whether it had ever been kept, or ever been tested. An empty list is at least a claim you can check, and it commits the site to filling it in.
The first entry will be worth more than any finding on the site. Work that publishes its own failed checks is auditing itself; work that also publishes what a stranger caught is being audited.
Reporting one
Every page on this site carries a line at the foot of it that opens a pre-filled issue naming that page. You do not need to know which figure is wrong, or why — “the second chart does not match the number in the sentence above it” is a complete and useful report. If you would rather not use GitHub, email works and costs you nothing in visibility.
You are not expected to be right. A report that turns out to be mistaken costs a reply and nothing else, and it is not published anywhere. That asymmetry is deliberate: the cost of a wrong report should be near zero, because the cost of an unreported error is a page that stays wrong.
What happens next
A correction is a new version with the old one still reachable, never a silent edit. If it changes a finding, the page says so where the finding is, not only here. If it changes only the prose, it appears here and nowhere else.
How much ceremony a change needs
Scaled to what actually changes for a reader, because treating every edit the same way is how the important ones get lost among the typos.
| What changed | What it needs |
|---|---|
| Typo, broken link, clearer wording | Nothing. Edited freely — no reader's understanding changes. |
| A number moves | A visible updated date and one line saying what changed. Somebody may have quoted the old figure. |
| The conclusion changes | A new version, with the old one still reachable. Never a silent edit. |
The middle row is the one that gets skipped, and it is the one that matters. A number that changes without a date is how a reader ends up citing something that is no longer on the page.
When new data changes the answer
These instruments are re-runnable, so they get re-run — and sometimes a finding does not survive newer data. That is not a maintenance problem, it is a result: this held in 2024 data and does not hold in 2026 data is worth publishing, and almost nobody tests it systematically.
The earlier version stays reachable, stamped superseded. It is something that happens to a case rather than a state anybody selects.
You are credited by name unless you ask not to be, and the credit sits beside the correction rather than in a list of acknowledgements nobody reads. Affiliation is only shown if you supply one; several of these instruments recalculate figures that somebody defends professionally, and the cost of putting your name to that is yours to weigh, not mine.
How credit works
A correction is credited to whoever found it, by name, beside the correction itself. Affiliation appears only if you supply one. If you would rather not be named, say so and the entry reads Anonymous — the correction still gets published.
What this page is not
It is not a changelog. Ordinary revisions — a redrawn chart, a clearer sentence, a new month of data — are visible in the repository's history and do not appear here. This page is only for the case where something published was wrong.
Found something wrong on this page? Report a correction — it opens a pre-filled issue — or email taufik.adi@openstudy.id. Corrections are credited by name in the errata, and one that changes a finding says so on the page.
