The answer is more often “yes” when referring to academic studies, as your Wikipedia source calls out via a reference to https://gwern.net/doc/statistics/2016-cook.pdf https://gwern.net/doc/statistics/2016-cook.pdf > A 2016 study of a sample of academic journals (not news publications) that set out to test Betteridge's law and Hinchliffe's rule (see below) found that few titles were posed as questions and of those, few were yes/no questions and they were more often answered "yes" in the body of the article rather than "no". Thankfully the underlying study doesn’t pose a question, and the article we are discussing here is an academic hypothesis more than news.
