Copy editing and fact-checking problems with practical fixes

What to take away

• Smooth prose can conceal an unsupported or overstated claim.
• Editing a quotation for grammar can change meaning or voice.
• Attribution does not excuse publishing a claim without scrutiny.
• Number errors often begin with missing definitions and baselines.
• Late package text needs the same accuracy review as the article.

Accuracy failures are rarely limited to typographical mistakes. They often begin when roles blur, source material arrives late, an editor assumes another person checked a line, or layout changes escape the original review. Fix the workflow at the point where the risk enters.

Problem: the editor improves certainty

Fix

Compare modifiers and verbs against the source. Changing "may contribute" to "causes" or "one of the largest" to "the largest" creates a new claim. Query uncertainty instead of deleting it for pace. The Journalist's Resource's tip sheet on helping journalists avoid errors observes that many journalists have not studied research methods and do not always know when causal language is warranted, and it advises researchers to say plainly whether a study supports a causal reading. An editor who cannot answer that question about a sentence should query it rather than tighten it.

Problem: attribution is treated as verification

Fix

Ask how the source knows, whether the information falls within that person's role, what motive or limitation exists, and what record can corroborate it. "According to" tells readers who said something; it does not establish that the statement is true.

Problem: a quote is cleaned into a different voice

Fix

Check exact words and context. Remove harmless repetition only under the publication's policy. If spoken wording would confuse readers or expose a person to needless ridicule, use faithful paraphrase outside quotation marks. Never improve the source's argument.

Problem: percentages lose their baseline

Fix

Write the old value, new value, unit, period, denominator, and whether the change is relative or in percentage points. Recalculate from the source table. Ask whether revisions, inflation, seasonality, uncertainty, or changing definitions affect the comparison.

Problem: the copy is read only on screen in normal order

Fix

Use several mechanical views. Poynter's list of ways to clean copy and reduce errors recommends reading aloud to catch dropped words, transpositions, and misplaced phrases, along with slowing down and consulting original source material rather than relying on copied versions.

Problem: tracked changes hide a factual shift

Fix

Classify changes by risk. Style changes can move through normal review. Changes to facts, claims, quotations, chronology, legal meaning, or portrayal should return to the writer, checker, or assigning editor. A clean-looking accepted version should not erase who approved the decision.

Problem: headline and caption arrive after checking

Fix

Add package fields to the claim sheet. Require a brief accuracy review after the final headline, deck, caption, pull quote, chart label, and social text are entered. Display copy often compresses language, which makes overstatement more likely.

Problem: nobody knows which file is final

Fix

Use one authoritative version with named owners and timestamps. Lock superseded proofs, record late changes, and compare the released package with the approved proof. If several platforms publish from different systems, define how corrections propagate.

Common questions

Can a copy editor challenge a reporter's fact?

Yes. The question should be specific, neutral, and tied to the wording or evidence.

Is reading aloud worth the time?

Yes. It reveals missing, repeated, and awkward language that silent reading can skip.

May a quote's grammar be corrected?

Follow publication policy and preserve meaning and voice. Paraphrase when correction would become rewriting.

What should happen after a factual late change?

Recheck the new wording and every dependent element before release.
