1 The rule in plain terms
A headline is a promise. It tells the reader what the story contains, and the reader decides from that promise whether to spend time on the copy. The rule is simple: the headline may compress, sharpen, and select, but it may not claim more than the story supports. If the body reports a possibility, the headline cannot report a fact. If the body describes one agency's action, the headline cannot imply the whole government moved. If the body quotes a single person's estimate, the headline cannot present that estimate as a settled finding.
Think of the headline and the story as two halves of one statement. The story establishes what is known, how it is known, and how far the conclusion reaches. The headline then restates the strongest version of that same claim in fewer words. Compression is expected and welcome; amplification is not. A headline that says a policy will change the way a system works is making a prediction. Unless the copy contains that prediction from a responsible source, or the change is already in force, the headline has crossed from summary into invention.
The test is not whether the headline is technically defensible under some strained reading. The test is whether a reasonable reader, having finished the story, would feel the headline told the truth. That standard protects both the reader and the publication, and it is the standard a copy desk applies before anything else.
2 Why editors enforce it
Credibility is the only currency a news or feature operation has, and headlines are where that currency is minted or counterfeited. Readers who click a headline expecting one story and find another do not blame the writer or the editor; they blame the publication. The damage compounds because headlines travel farther than stories. They appear in feeds, alerts, aggregators, and screenshots, often stripped of the copy that would have qualified them. A headline that overpromises is therefore not a small local error; it is the version of the story most people will ever see.
Editors also enforce the rule because it disciplines the reporting. If a headline cannot be written without overstating, that is usually a signal that the story itself has not settled its central claim. The desk then asks the useful question: what do we actually know, and how strongly do we know it? Sometimes the answer is a narrower headline. Sometimes it is a rewrite of the lede. Occasionally it is a decision to hold the story until the claim is firmer. All three outcomes are better than a headline that borrows certainty the copy has not earned.
Finally, the rule protects against a subtler failure: the headline that is literally true but misleadingly framed. A story about a modest pilot program can be headlined as a sweeping change if the writer leans on the most expansive noun available. Nothing in the copy is false, yet the impression is. Editors treat impression as part of accuracy, because readers do.
3 Where writers usually slip
The most common slip is verb inflation. The copy says officials discussed, considered, weighed, or signaled; the headline says they moved, acted, or decided. Discussion is not decision, and a headline that promotes one to the other misstates the story's stage. A related slip is noun inflation: a proposal becomes a plan, a plan becomes a policy, a policy becomes a program, and a program becomes a mandate. Each step sounds more concrete than the last, and each step takes the headline further from the copy.
Certainty is the second trap. Reporters hedge for good reason, because sourcing is partial and outcomes are open. Headlines tend to strip hedges because hedges are wordy. But removing may, could, is expected to, or according to early estimates changes the claim, not just its length. A headline that drops a hedge is asserting what the copy only suggested. The fix is rarely to cram the hedge back in; it is to find a headline built on what is already certain, such as the existence of the debate, the filing of the proposal, or the fact of the delay.
Scope is the third trap. A story about one region, one agency, one company, or one group can be headlined as though it covered all of them. Readers infer breadth from unqualified nouns. If the copy says a handful of schools, the headline should not say schools. If the copy says one state's regulators, the headline should not say regulators. Scope errors are especially damaging because they are invisible to anyone who only reads the headline, which is most of the audience.
4 Applying the rule on deadline
On deadline, the practical method is to write the headline from the story's strongest verified sentence rather than from the writer's memory of the reporting. Find the sentence the copy would defend under questioning, then compress that. If the strongest sentence is qualified, the headline inherits the qualification. If the strongest sentence is narrow, the headline stays narrow. This keeps the headline anchored to text that already survived editing.
Next, test the headline against the first three paragraphs. A reader who stops there should not be surprised by the rest of the story, and a reader who reads only the headline should not be misled about those paragraphs. If the headline promises a conclusion the lede does not support, either the headline is wrong or the lede is buried. Both are fixable, and the fix is faster than a correction.
Then check the verbs and nouns for load. Replace any verb that implies a completed action with one that matches the copy's stage. Replace any broad noun with the specific one the story uses. Read the result aloud and ask what a skeptical reader would expect to find. If the expectation is larger than the story, trim the headline, not the story. Finally, confirm that numbers, dates, and attributions in the headline appear in the copy in the same form. A headline is not a place to introduce a figure or a claim that the body never states.
5 Legitimate exceptions
The rule bends in one direction: a headline may generalize when the story's central finding is unambiguous and the shorter wording preserves the same meaning and certainty. If the copy reports that a long-running dispute ended with a signed agreement, the headline can say the dispute ended without naming every party or restating every term. Compression is not overpromising when the compressed claim is the same claim.
Headlines may also use a vivid or figurative word when the figure is clearly figurative and the literal claim underneath is accurate. A story about a budget that shrinks can be headlined with a word like squeezed, provided the copy supports a reduction. The figure adds color; it does not add a new assertion. The line is crossed when the figure could be read as a literal claim the copy does not make, or when the color implies an outcome, such as victory or collapse, that the story leaves open.
Finally, a headline may pose a question when the story genuinely examines that question and does not pretend to answer it. A question headline is honest only if the copy treats the question as open. If the copy has an answer, the headline should state it rather than tease it. Teasing an answer the story already contains is a different failure, but it belongs to the same family: the headline withholding or inflating what the copy delivers.
6 A worked example from the copy desk
A reporter files a story about a regional transit agency that has released a proposal to adjust fares. The proposal has not been voted on. The board has scheduled a discussion. Riders have criticized the plan, and one official says the changes could take effect next year if approved. The first headline draft reads: Transit agency raises fares. Every word is wrong. The agency has not raised anything, the board has not voted, and the timing is conditional.
A second draft reads: Transit agency proposes fare increase. This is closer, but the copy says the agency released a proposal, not that the agency itself formally proposed it, and the story's news is the board's scheduled discussion. The desk settles on: Transit board to discuss fare proposal. That headline is narrower, but it is exactly what the copy delivers. It names the body that will act, the action that is scheduled, and the item at issue. A reader who continues finds the proposal details, the criticism, and the conditional timeline, none of which the headline overstates.
The desk also considers a question headline, such as Will transit fares rise? That form is defensible only if the story genuinely leaves the question open. Here the story does leave it open, so the question headline would not be dishonest. The desk still prefers the declarative version because it conveys more information and because question headlines can read as clickbait even when they are fair. The deciding principle is the same in both cases: the headline reports the state of play the copy actually describes, no more and no less.
7 Quick reference and related rules
Match the headline's claim to the strongest verified statement in the copy. Keep the copy's hedges or replace them with a narrower claim. Keep the copy's scope. Do not promote discussion to decision, proposal to policy, or possibility to fact. Do not introduce numbers, names, or attributions the body does not contain. Read the headline as a skeptical reader and ask what story it promises; if that story is bigger than the copy, rewrite the headline.
Related rules reinforce the same discipline. Headline capitalization follows the publication's style, and consistency matters because inconsistent capitalization signals carelessness that readers extend to the copy. Verb tense in headlines usually stays in the present for recent action and the infinitive for future action, which keeps timing honest; a past-tense headline can imply completion the story has not reached. Punctuation in headlines, including the comma used for and and the colon used to introduce a speaker or a summary, should clarify rather than dramatize. Attribution in headlines should name the source when the claim is contested, and should not imply institutional endorsement of a single person's view.
One more related habit: avoid the false balance headline that pairs two unequal claims as though they carried equal weight. If the copy reports a finding and a denial, the headline should not present the denial as an equivalent result. The headline's job is to represent the story's actual state of knowledge, and that state is rarely symmetrical. When in doubt, write the headline from the sentence the copy would defend, and let the rest of the story carry the nuance.
