Super Freakonomics Steven Levitt & Steven Dubner

I loved Freakonomics and I was very excited to read Super Freakonomics. I have to say I was very disappointed in the follow up to the best seller.  
Review
But perhaps the best example of incentives colliding with unintended consequences is, well... Super Freakonomics. The original Freakonomics  --  a bestselling, entertaining work published in 2005 by the duo of famed economist Steven Levitt and journalist Stephen Dubner --  did a grand job popularizing economic analysis and convincing people that enough economists armed with enough data could not only solve most of the world's problems, but be wry and interesting along the way. Freakonomics was followed by a rush of economists-explain-it-all books, including Tim Harford's Undercover Economist, Tyler Cowen's Discover Your Inner Economist, and Robert Frank's Economic Naturalist.
