By my reckoning only 7 articles out of 20 conform with Betteridge’s Law i.e.: “Any headline which ends in a question mark can be answered by the word no” (there’s one that isn’t a question). I count 7 that are answered with a yes and the remainder aren’t yes or no questions. (1)
Because I didn’t start posting in 2015 until after the holiday season ended, the list also includes articles put up in January.
