A long pondered but only lately realized blog about economics, politics, evaluation, econometrics, academia, college football and whatever else comes to mind.

Atlas Shrugged reviews
I don't think I've ever seen a bigger divergence between the ratings of the critics on Rotten Tomatoes and the ratings of the viewers than the one for Atlas Shrugged, Part I. The problem, of course, is that the critics' ratings are biased downward for political reasons while the viewers' ratings are biased up due to self-selection on political views. In formal jargon, this means that the "true" rating is only set-identified, and the set is a big one. Put somewhat less technically, the two sets of ratings bound the truth and in this case, as in so many others, the bounds are too wide to be informative.
