The phrase man bites dog is a shortened version of an aphorism in journalism that 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.
The phenomenon is also described in the journalistic saying, "You never read about a plane that did not crash." It can be expressed mathematically; a basic principle of information theory is that reports of unusual events provide more information than those for more routine outcomes.
Origins
The phrase was coined by Alfred Harmsworth, 1st Viscount Northcliffe (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).
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.
Effect
To some extent, a focus on unusual occurrences is unavoidable in journalism, as events that proceed as expected are simply not "newsworthy".
The reasoning errors caused by this phenomenon are also associated with the availability heuristic, which is the mental shortcut that relies on the immediate examples that come to mind when evaluating a specific topic. For example, because airplane crashes are frequently reported, they are easy to call to mind. This leads to people having inaccurate perceptions of how dangerous air travel is.
Some consider "man bites dog" stories about unusual events a sign of yellow journalism, and in the internet era, headlines about them may be phrased as click bait.
Mathematical analysis
A basic principle of the information theory, which studies the mathematical theory of communication, is that reports of unusual events provide more information than those for more routine outcomes. The amount of information conveyed by a message about an event can be expressed in terms of its "surprisal", with surprisal defined as for an event of probability . Measured this way, an event that is nearly certain to happen ( very close to one) carries almost no information, while an extremely rare event ( very close to zero) provides a very large amount of information.
