For news/article headlines, I estimate 90% are No, if they are Yes/No questions. The reason is, the author had nothing interesting/new to tell, but needs to bait people to visit the news site to make money.

However, this Wiki page has some actual studies about it, not just my personal estimate: https://en.m.wikipedia.org/wiki/Betteridge's_law_of_headlines

Also, there’s a new trend of adding “Here’s why” to the end of headlines of really bad news articles.
