Accountability

Corrections policy

Last updated June 14, 2026. Status: evergreen publication policy.

Measurement Press corrects errors in fact, citation, calculation, framing, interpretation, and disclosure so readers can see what changed and how much confidence the current page deserves.

Reader standard: a correction should identify the affected claim, the better evidence or wording, the date of the change, and whether the conclusion changed.

Correction trust route

Use this route when a reader wants to move from a suspected issue to the evidence, source, funding, privacy, or paid-placement standard that decides whether a correction is needed.

Reader report Start with the affected claim Identify the page, passage, suspected issue, supporting evidence, and whether the conclusion should change. Evidence standard Match the claim to support Use the methodology when a correction depends on evidence grade, causal language, uncertainty, or case-study limits. Source trail Check the citation path Review source proximity, incentives, denominators, comparisons, and claim support behind the disputed passage. Independence Review commercial boundaries Confirm that funding, sponsorship, or advertiser interest did not alter evidence treatment or correction handling. Reader data Check privacy expectations Use the privacy page when a report concerns analytics, advertising technology, data handling, retention, or choices. Paid disclosure Clarify ad and sponsor labels Use advertising standards when a correction involves paid placement, native labeling, sponsorship fit, or disclosure clarity.

Correction intake questions

What should a correction report include?

A useful report includes the page URL, quoted passage, suspected issue, supporting evidence, and whether the page conclusion should change.

When does an edit need a visible correction note?

A visible note is appropriate when an update changes how a reader understands a claim, source, number, disclosure, or conclusion. Routine clarity or formatting updates usually do not need a full correction note.

How are source or citation problems reviewed?

Source problems are checked against citation proximity, source independence, method detail, denominator clarity, and whether the affected claim still follows from the evidence.

What happens when a number or denominator is wrong?

The page should correct the figure, restate the comparison, review nearby conclusions, and note whether the corrected number changes the allowed claim.

How are advertising or sponsorship disclosure issues handled?

Missing or unclear commercial disclosures should be corrected promptly, with the affected placement or page identified and the editorial conclusion checked separately from the paid relationship.

What qualifies for correction

A correction is warranted when a page gives readers a materially wrong fact, stale source, broken evidence trail, incorrect calculation, unclear denominator, overstated causal claim, missing disclosure, or conclusion that no longer follows from the cited evidence.

Small copy edits may be made without a public note when they do not change meaning. Any edit that changes the reader's understanding of a claim, source, number, or conclusion should be logged on the affected page or in a clearly visible revision note.

Correction levels

Level	Example	Action	Reader-facing note
Minor	Typo, grammar issue, duplicate word, or formatting problem.	Fix the page without changing the evidence or conclusion.	Usually not required unless meaning changed.
Source	Broken archive link, stale document, mismatched citation, or source label that needs clarification.	Update the citation and check related passages that rely on the same source.	Note the source change when it affects confidence, context, or traceability.
Statistical	Wrong denominator, arithmetic error, mislabeled sample, incorrect period, or missing uncertainty language.	Correct the number, restate the comparison, and review nearby conclusions.	State the corrected figure and whether the conclusion changed.
Framing	A headline, summary, or causal verb reads stronger than the evidence supports.	Revise the language to match the evidence grade and disclose the framing update.	Explain the old wording and the more precise claim.
Retraction	The core claim is unsupported after review.	Preserve the page with a clear retraction notice or replace the body with a retraction record.	State why the claim should no longer be relied on.

How reader reports are reviewed

Useful reports include the page URL, quoted passage, the suspected issue, supporting evidence, and the correction the reader believes would make the page more accurate. Reports about tone or emphasis should identify the specific wording, source treatment, denominator, comparison class, or missing context at issue.

Reports are reviewed against the publication's methodology, the relevant source trail, and any primary documents, data notes, or measurement assumptions cited by the page. When a report raises a plausible substantive issue, related pages may also be checked for the same source, number, or framing pattern.

Revision notes

A public correction note should be close to the affected article or guide, not hidden in a separate changelog. The note should include the date, the original problem, the correction made, and whether the conclusion changed. When an update improves clarity without changing the claim, the note should say that too.

Pages may also receive routine updates for source freshness, new internal links, accessibility improvements, search metadata, or formatting. Those changes do not need full correction treatment unless they alter a claim, evidence grade, disclosure, or reader decision.

Advertising and sponsorship disclosures

If an advertising, sponsorship, affiliate, native placement, or commercial relationship disclosure is missing or unclear, the page should be corrected promptly. Editorial judgments, source grades, and corrections should not depend on whether an advertiser, sponsor, vendor, or publisher partner prefers a particular conclusion. Use the advertising standards page for the reader-facing disclosure boundary.
