How do I report an error in Harpd data?

Contact Harpd with the claim id or dataset URL and the figure you believe is wrong. Corrections are made against the dataset and recorded, not patched in the article that quoted it.

Quick answer

How do I report an error in Harpd data?

A data error report is a request to correct a published Harpd figure. Because every Harpd number traces to a claim, a dataset and a methodology, an error report can be resolved precisely rather than by rewriting prose.

  • Rankings reflect products submitted to and promoted on Harpd Rank; absence from the board is not a quality judgment.

How it works

The mechanics, plainly

Send the claim id (from /citations/) or the dataset URL, the figure you believe is wrong, and the source you are comparing against. Harpd checks the claim against its dataset and its evidence chain. If the dataset is wrong it is corrected and the claim re-verified; if the claim is wrong it is blocked or revised and the register reflects that.

Why it matters

Correcting the source fixes every downstream copy at once. Correcting an article fixes one. Publishing the claim registry is what makes the first option possible, and it is why a correction request is a contribution rather than a complaint.

Frequently asked questions

What if a third party quoted an old Harpd figure?

Tell Harpd anyway. Because each figure carries a data date, the registry can confirm whether the quoted number was correct when it was taken — which distinguishes a stale quote from a genuine error.

How do I find the claim id for a number?

Search /citations/ for the claim, or read /data/claims.json. Each entry carries a stable claimId that can be used in the report and in a deep link.

Does Harpd remove a corrected figure?

Corrections update the dataset and the claim; the registry records the current status rather than silently deleting history, so a reader can see that something changed.
