I found the fact that something predicts school success better than IQ very interesting considering about all IQ predicts well is school success. For me it really confirmed the idea that what IQ measures isn't as fundamental a representation of cognitive ability as I grew up believing. I realise psychologists have moved onto a notion of 'g' but they still assume its highly correlated with IQ.
I strongly disagree with your assessment of the rest of the article, it seems like you're trying hard to fit it in to a particular world view. Concentration is not obedience, its vastly more important, and I don't think the lack of concentration shown was simply as a result of the childrens new aversion to obedience (if such a thing exists).
