5 out of 5 stars
It's simply the best of the Freakonomics blog
It's similar to the other books in their series but takes small excerpts, updates, and guest speakers from the long running Freakonomics blog to compile the next chapter in the saga
4 out of 5 stars
The Weakest of the Four.
The Weakest of the Freakonomics books, but still very entertaining and enlightening. I highly recommend.
