but 5 years before – Andrew Marr wrote
If the headline asks a question, try answering ‘no’. Is This the True Face of Britain’s Young? (Sensible reader: No.) Have We Found the Cure for AIDS? (No; or you wouldn’t have put the question mark in.) Does This Map Provide the Key for Peace? (Probably not.) A headline with a question mark at the end means, in the vast majority of cases, that the story is tendentious or over-sold. It is often a scare story, or an attempt to elevate some run-of-the-mill piece of reporting into a national controversy and, preferably, a national panic. To a busy journalist hunting for real information a question mark means ‘don’t bother reading this bit’
So … why is it called Betteridge’s Law ?
