Quick answer
Betteridge’s Law of Headlines says a headline that ends in a question mark can usually be answered with “no”. It is a rule of thumb, not a real law. It works because publishers often use a question when they cannot prove a bold claim. It is a useful warning sign for clickbait, but it is not right every time.
Headlines such as “Is this the end of the high street?” or “Has your provider been overcharging you?” are everywhere. Many follow a pattern with its own name: Betteridge’s Law of Headlines.
This guide gives you the plain answer first, then the detail. You will see what the law means, who really said it first, some examples, what the research says about whether it holds up, and a simple way to use it. We also cover Parkinson’s Law, Price’s Law, ostriching and open looping, because people often search for them alongside Betteridge’s Law.

What Is Betteridge’s Law of Headlines?
Betteridge’s Law is a journalism rule of thumb. If a headline asks a yes/no question, the honest answer is usually “no”. The reasoning is simple: if a publisher had solid proof, it would state the claim plainly. A question lets it hint at something exciting without standing behind it.
The law only covers yes/no questions. Open questions, such as “How do I renew a passport?”, are not covered. It is also not a law in the scientific or legal sense. It is a humorous saying, in the same family as Murphy’s Law.
Who Is Ian Betteridge?
Ian Betteridge is a British technology journalist. On 23 February 2009 he wrote a post called “TechCrunch: Irresponsible journalism” on his own blog, Technovia. It criticised a TechCrunch headline: “Did Last.fm Just Hand Over User Listening Data To the RIAA?” The headline suggested that the music service had passed listening data to the record industry’s trade body.
Betteridge used it as an example of his maxim about question headlines. His name stuck, and the idea became known as Betteridge’s Law. A common mistake is to say the post appeared on TechCrunch. It did not; it was on Betteridge’s blog, and it was aimed at TechCrunch.
Where Did the Law Really Come From?
Betteridge popularised the name, but he did not invent the idea. Earlier versions were in print years before his post.
| Year | Source | What it shows | How sure are we? |
|---|---|---|---|
| By 1988 | Hinchliffe’s Rule | The same idea for physics paper titles: a yes/no question title gets the answer “no” | Dated by adage researchers; original not checked |
| 1991 | “Davis’s Law”, in a collection of Murphy’s Law variants (Arthur Bloch) | The first printed version we found for news headlines. Who Davis was is unknown | Secondary sources only |
| 2004 | Andrew Marr, My Trade | Advice to readers: if the headline asks a question, try answering “no” | Secondary sources only |
| 2007 | Commentary on journalism | Described the idea as an old truism among journalists | Author not identified |
| 2009 | Ian Betteridge, Technovia | Gave the idea the name we use today | Well documented |
A note on what we could and could not check
We could not open Betteridge’s original 2009 page or the 1991 book ourselves. These details come from reliable secondary sources. Also, “no earlier use found” does not mean no earlier use exists.
Why Do Publishers Use Question Headlines?
There are three main reasons.
- They create curiosity. A question opens a gap, and readers click to close it. Marketers call this an open loop (see the section on open looping below).
- They work as clickbait. A dramatic question is cheap to write and easy to share. Video makers feel the same pull, because views turn into income, as our guide to how much YouTube pays explains.
- They avoid a firm claim. A statement can be proved wrong. A question is harder to challenge, because the publisher never said it was true.
The trick is much older than the internet. In 1883, Joseph Pulitzer’s New York World ran the headline “Was It Peppermint Mary?” over a story about a jeweller’s shop that tried to stop its female staff flirting with passers-by. “Peppermint Mary” only appeared at the end, as a possible cause, and the story never answered the question.
Betteridge’s Law Examples
The headlines in the table below are invented to show the pattern. They are not real headlines. The best-known real example is the Last.fm headline above.
| Example headline (invented) | Why | Does the law apply? |
|---|---|---|
| Is This the Best Smartphone Ever? | A big claim with nothing you can test | Probably yes |
| Is Your Energy Provider Hiding a Secret Charge? | Alarm with no named source | Probably yes |
| Is This Celebrity’s Career Over? | Hints at drama without evidence | Probably yes |
| Do You Need a Passport to Fly From London to Paris? | A real question with a clear answer: yes | No |
| How Does the Bank of England Set Interest Rates? | An open question, not yes/no | Not covered |
When a question headline is genuine
- The article answers the question with evidence, and the answer is “yes”.
- The topic is truly uncertain, so “we do not know yet” is the honest answer. This is common in science.
- It is an open “how”, “why” or “what” question, which the law does not cover.
Is Betteridge’s Law True?
Not always. It is a handy warning sign for sensational stories, not a rule that is right every time. Betteridge himself has described it as a throwaway remark.
Most studies look at academic article titles, because they are easy to collect. A 2016 study in Scientometrics by James Cook and Dawn Plourde checked every title published in 2014 in ten journals in each of six fields, 7,845 titles in all. Only 177 (2%) were questions, and 85 of those were yes/no questions. The authors reported that question titles were rare and did not back up the rule.
A 2018 study of 2,585 articles in four ecology journals looked at the answers to yes/no question titles. As reported by Wikipedia, “no” was the least common answer.
These are science papers, where a question can be a fair way to state what a study is trying to find out. News headlines work differently, and we could not find a large, well-documented study of UK news headlines. Treat the numbers as a limit on the law, not a final verdict.
| The law is more likely to work when… | The law is more likely to fail when… |
|---|---|
| The headline is a dramatic yes/no question about a person, brand or scandal | The topic is science or something with no settled answer |
| No source or evidence appears in the headline | The article gives a clear, sourced answer, often “yes” |
| The wording is a superlative or an alarm (“best ever”, “secret”, “the end of”) | The question is a genuine “how”, “why” or “what” question |
How to Use Betteridge’s Law to Spot Clickbait
- Check it is a yes/no question. If it is an open question, the law does not apply.
- Look for a claim you could test. Vague drama with nothing concrete is a warning sign.
- Read the first few paragraphs. Does the article answer the question with named sources?
- Check the date. Old stories are often shared again as if they were new, so it helps to know how to find the publication date of a website.
- Search for the claim elsewhere. If only one site is making it, be careful. When you search on Google, you can exclude words from a Google search to cut out noisy results.
- Do not judge by the headline alone. A question mark is a clue, not proof.
If you write headlines yourself, state the claim when you can prove it, and ask an open question when you cannot. A quick editing pass, for example with the tools in our Grammarly vs ChatGPT comparison, also helps tighten the wording.
Related Laws and Ideas
The ideas below often appear in the same searches. They describe different things, so they are kept short and separate here.
Parkinson’s Law
Parkinson’s Law says work expands to fill the time available. It comes from a satirical essay by the naval historian C. Northcote Parkinson, published in The Economist on 19 November 1955. Its opening sentence says work expands “so as to fill the time available for its completion”.
The essay was really about bureaucracy. Based on the British Civil Service, Parkinson argued that staff numbers grow whatever the workload. In everyday life, the idea is easy to spot: give yourself a week to write one email and it will probably take a week.
Parkinson’s Law of Triviality (bikeshedding)
This is a second idea from Parkinson’s 1957 book. Groups spend more time on small, easy topics than on big, complex ones. In his example, a committee approves a nuclear reactor quickly but argues for ages about a bicycle shed, because everyone understands a shed. The first law is about time. This one is about attention. In software it is often called bikeshedding.
Price’s Law
Price’s Law says the square root of the number of contributors produces about half of the output. Derek J. de Solla Price, a British physicist and historian of science, proposed it in Little Science, Big Science (1963). He was describing scientific papers: half of a field’s papers come from the square root of its authors.
| Group size (N) | Square root of N | Share of the group |
|---|---|---|
| 10 | about 3 | about 32% |
| 100 | 10 | 10% |
| 1,000 | about 32 | about 3.2% |
| 10,000 | 100 | 1% |
The rule is a rough guide at best. A 1988 study tested Price’s square-root claim against real and simulated author data and found that the data did not support it. Lotka’s Law fits better. Using Price’s Law for sales or software teams is an extension of the original idea. It is not proven.
Ostriching (the ostrich effect)
Ostriching is an informal word for avoiding information because it might be bad news, like not opening a bank statement after a heavy month. It is not a law and has no single inventor. In behavioural finance, it is known as the ostrich effect. A 2009 paper by Niklas Karlsson, George Loewenstein and Duane Seppi found that investors check their portfolios more in rising markets than in flat or falling ones.

The evidence is mixed. A 2014 study of 617 investors at Barclays Wealth in the UK found no sign that they tried to avoid bad news.
Open looping
Open looping has two meanings. In productivity, an open loop is an unfinished task that stays on your mind, a term popularised by David Allen’s Getting Things Done. In marketing, it means leaving a question or story unresolved so people keep reading or watching, as in a cliffhanger or a teasing email subject line.
Both ideas are linked to the Zeigarnik effect from 1927: the claim that people remember interrupted tasks better. A 2025 meta-analysis found no memory advantage for unfinished tasks, although people do tend to want to resume them. So open loops work through curiosity and the urge to finish, not better memory. A question headline is a simple open loop, which is why it connects to Betteridge’s Law. For wider figures on how brands compete for attention, see our marketing statistics guide.
Quick Comparison Table
| Concept | Main idea | Credited to | Field | How solid is the evidence? |
|---|---|---|---|---|
| Betteridge’s Law | Yes/no question headlines can usually be answered “no” | Ian Betteridge, 2009 (earlier versions exist) | Journalism | Rule of thumb; studies of academic titles do not support it |
| Parkinson’s Law | Work expands to fill the time available | C. Northcote Parkinson, 1955 | Management | Satire built on civil service observations |
| Law of Triviality | Groups focus on small, easy topics | C. Northcote Parkinson, 1957 | Committees | Observation |
| Price’s Law | The square root of contributors gives half the output | Derek J. de Solla Price, 1963 | Research and productivity | Tested in 1988; did not hold |
| Ostrich effect | People avoid information that may be bad news | Karlsson, Loewenstein and Seppi, 2009 (popular use) | Behavioural finance | Some support; a UK study found none |
| Open looping | Unfinished stories or tasks keep attention | No single originator | Marketing and psychology | Memory effect not found in a 2025 meta-analysis |
Why Betteridge’s Law Still Matters
Headlines now compete for attention on feeds that reward clicks, and the latest social media statistics show how big those audiences are. A question mark is a quick signal to slow down. It will not tell you whether a story is true, but it reminds you to look for the evidence before you share.
Frequently Asked Questions About Betteridge’s Law
What is Betteridge’s Law in simple words?
It is a rule of thumb that a yes/no headline ending in a question mark can usually be answered with “no”. Publishers tend to use a question when they cannot back up a bold claim.
Who created Betteridge’s Law?
Ian Betteridge, a British technology journalist, gave it his name in a February 2009 blog post. Earlier versions were already in print.
Did Ian Betteridge invent the law?
No. He popularised the wording, but a 1991 Murphy’s Law compilation recorded it as “Davis’s Law”, and Andrew Marr gave similar advice in 2004.
What is Betteridge’s Law of Headlines?
It is the full name of the same rule. It covers yes/no question headlines, not open questions such as “How does this work?”.
Is Betteridge’s Law always true?
No. It is a humorous rule of thumb. Studies of academic titles found that “yes” was the most common answer to yes/no question titles, and news headlines have not been tested at scale.
What are some examples of Betteridge’s Law?
The best-known real example is the 2009 TechCrunch headline about Last.fm and the RIAA. Vague, dramatic questions about brands, celebrities or scandals are the usual pattern.
Why do journalists use question marks in headlines?
To create curiosity, to attract clicks, and to hint at a story without stating it as fact.
Is Betteridge’s Law related to clickbait?
Yes. It is mainly used as a quick test for clickbait, because teasing questions are a common clickbait style.
What is the difference between Betteridge’s Law and Parkinson’s Law?
Betteridge’s Law is about headlines. Parkinson’s Law is about time: work expands to fill the time available.
What is Parkinson’s Law of Triviality?
It says groups spend more time on small, easy topics than on big, complex ones. It is also called bikeshedding.
What is Price’s Law in productivity?
It says the square root of the number of contributors produces about half of the output. It began as a claim about scientific papers and is a rough idea, not a proven rule for workplaces.
What does ostriching mean?
It is an informal word for the ostrich effect: avoiding information because it might be bad news, such as not checking a bank balance.
What is open looping in marketing?
It means leaving a question or story unresolved so people keep reading or watching to find the answer, as in a cliffhanger or a teasing email subject line.
Conclusion
Betteridge’s Law says a yes/no headline ending in a question mark can usually be answered with “no”. Ian Betteridge gave it its name in 2009, but earlier versions go back to at least 1991. It is a useful test for clickbait, not a universal rule: studies of academic titles show that “yes” is often the answer, and news headlines have not been tested at scale. Use the question mark as a prompt to check the facts, not as a verdict.
