Copied from Wikipedia because I didn’t know: 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, 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.
