In one of the most compelling and entertaining films of the year, documentarian Albert Nerenberg asks one simple question: What is stupidity? It's much harder to answer than you might think, for, as Einstein theorized, the universe and stupidity are the only things that are infinite--and he had his doubts about the former. Amazingly, there has been no real academic study on stupidity, and there are only a handful of serious books on the topic, but that doesn't stop Nerenberg from blazing forward.
