When I read AG's original, I found the study report and I believe it was only a poster summary. I think those are meant more to tweak interest than to be definitive. My point is that this was a clearly limited effort and that the real problems, the real misleadings are in big studies with lots of charts and data appendices that hide what's really going on, what was left out, etc. These make the story telling much harder to unravel and they are more likely, I think, to become part of the continuing narrative.


jonathan: if you click to one of my two earlier posts on this topic, I have a link to the published paper. One of Gelman's readers found the paper while Andrew found the poster presentation. I'm glad we have both because the published paper only contains relative numbers-you can't find any absolute counts and so you can't judge what's in there.
