The problem with this sort of learning, though, is that there's no one to tell you if you're getting it wrong, no one to tell you about the recent Economist article nicely summarizes the problems with Beck's method:
If you try to teach yourself history and political science from scratch, you're likely to draw a lot of shallow and inaccurate conclusions, particularly when you're the sort of person who's predisposed to seeing things in terms of white hats and black hats. One role of instructors, particularly at the college level, is to smack down the sweeping generalisations and facile analogies their students tend to make, and try to force them to adopt more rigorous and complicated approaches. But what if you're surrounded by people who reward you handsomely for making sweeping, slanderous generalisations, both because it delivers ratings and because it's ideologically helpful?
