I know I'm not smart enough on statistics or psychology to evaluate the article but it always struck me that D&K seemed to say something similar to what my grandpa said when I was a wee lad, "The more you know, the more you realize how much you don't know", I know he wasn't the first person to say that, but he was the first person to say it to me. I don't know if D&K is autocorrelation or not, but I know that an awful lot of people seem to think they know more than maybe they actually do, probably me included. Hmmm, maybe the author of that article as well? I wonder if that occurred to him, seems like a glaring oversight not to at least recognize that possible irony.
