It was their typical crappy fish for the answer they want survey. I don't remember the exact wording, but from a scientific survey perspective, the questions (and more importantly the answers) contained wording that was inherently biased. If you craft questions and answers a specific way, you can always get the result you want. Which is exactly what AMA did.
They'll break their arm patting themselves on back. Go with the answers they drove people to give, and the magazine will still be garbage.
