SuperFreakonomics: Global Cooling, Patriotic Prostitutes, and Why Suicide Bombers Should Buy Life Insurance by Steven D. Levitt and Stephen J. Dubner

This "Freakquel" to Freakonomics covers such topics as "Why are doctors so bad at washing their hands?", "How effective are car seats?", and "Can eating kangaroo meat help save the planet?"  While some topics are relevant, intelligent discussions of common misconceptions, others seem to be included solely for arguments.  The authors like to include at least one salacious topic, but don't seem to care about whether they make sense or show any real depth.
