The phrase man bites dog is a shortened version of an aphorism in journalism which describes how an unusual, infrequent event (such as a man biting a dog) is more likely to be reported as news than an ordinary, everyday occurrence with similar consequences, such as a dog biting a man. An event is usually considered more newsworthy if there is something unusual about it; a commonplace event is less likely to be seen as newsworthy, even if the consequences of both events have objectively similar outcomes. The result is that rarer events more often appear as news stories, while more common events appear less often, thus distorting the perceptions of news consumers of what constitutes "normal" rates of occurrence.
The phenomenon is also described in the journalistic saying, "You never read about a plane that did not crash".
The phrase was coined by Alfred Harmsworth (1865–1922), a British newspaper magnate, but is also attributed to New York Sun editor John B. Bogart (1848–1921): "When a dog bites a man, that is not news, because it happens so often. But if a man bites a dog, that is news." The quote is also attributed to Charles Anderson Dana (1819–1897).
