🔗 Betteridge's Law of Headlines

Betteridge's law of headlines is an adage that states: "Any headline that ends in a question mark can be answered by the word no". It is named after Ian Betteridge, a British technology journalist who wrote about it in 2009, although the principle is much older. As with similar "laws" (e.g., Murphy's law), it is intended to be humorous rather than the literal truth. The adage fails to make sense with questions that are more open-ended than strict yes-no questions.

The maxim has been cited by other names since 1991, when a published compilation of Murphy's Law variants called it "Davis's law", a name that also crops up online (such as cited by linguist Mark Liberman), without any explanation of who Davis was. It has also been referred to as the "journalistic principle" and in 2007 was referred to in commentary as "an old truism among journalists".
