Andrew, you win Final Jeopardy. You and me both. I don't even remember when I let my subscription expire but I believe it was 15+ years ago by now. As for the myth, well, let's just say the first link I offered was also written quite a few years ago. Part of why I was so shocked to see that article is because it's precisely the kind of junk that led me to letting my subscription expire in the first place. Imagine my surprise when I saw the subject on Twitter, then realized it was linking to RW.
Charlene, right. They will be right back to promoting the 10% myth in no time. I have no doubt about it. They have never in the past let studies proving them to be wrong change what they promote. The interesting thing now is that there is hard evidence that they know they are full of it when they go back to promoting the myth.
