Josef Fruehwald has an excellent post "On vocal fry". (For some background, see "Vocal fry: 'creeping in' or 'still here'?", 12/12/2011.)
He observes that the media coverage has been an intellectual "train wreck", and he promises to explore the whys and wherefores in a future post. I'll look forward to his analysis — but I came to my own conclusion a few years ago ("Bible Science Stories", 12/2/2006):
I've concluded that "scientific studies" like these have taken over the place that bible stories used to occupy. It's only fundamentalists like me who worry about whether they're true. For most people, it's only important that they're morally instructive.
What would the producers of CNN Headline News, NPR's "Wait, wait, don't tell me" or the BBC's "Have I got news for you" say, if presented with evidence that they've been peddling falsehoods? I imagine that their reaction would be roughly like that of an Episcopalian Sunday-school teacher, confronted with evidence from DNA phylogeny that the animals of the world could not possibly have gone through the genetic bottleneck required by the story of Noah's ark. I mean, lighten up, man, it's just a story.
