We correct factual errors in the open and keep a record of the change. If you find a problem or a stronger primary source, send us a correction request.
Request a correction
Email corrections@chalklens.org or contact@chalklens.org. Use the subject line Correction Request: [URL or article title] and include:
- The article URL.
- The sentence, table cell, or figure in question.
- A short description of the problem.
- A link or attachment for the supporting source.
How we label changes
- Correction: A factual, attribution, or calculation error. We update the material and add a dated note.
- Clarification: The figure is right, but the wording could mislead readers.
- Update: A newer source adds information or replaces an estimate without proving the old figure false.
- Minor typographical fix: A spelling or grammar change that leaves the meaning intact.
We don’t silently rewrite substantive errors.
