This “law” doesn’t really hold up, according to that article’s studies section. I wholeheartedly agree that it’s a dirty and gross way to head something; but it was more interesting that the answer appears to more often be “yes”. Problem is there are so few examples of it (comparatively).

That's because it's no longer a journalistic article but an editorial.
