The book 'Freakonomics'

I am approaching the end of the book Freakonomics, A Rouge Economist Explores the Hidden Side of Everything by Stephen Dubner and Steven Levitt and immediatly it has launched towards the top of my all time favorites list. Levitt and Dubner essentially make the point that a correlation does not always equal a cause. Just because two things are consistently correlated, does not mean that one is causing the other, like a lot of 'conventional wisdom' will tell you. They take some of this basic 'convential wisdom' and turn it upside down, offering very unique angles on both important and simply interesting subjects.
