This was a pretty entertaining book with one of my favourite kinds of thinking, what can be (perhaps reductively) summarised as "unconventional wisdom" that uses data and information to challenge prevailing notions that are enmeshed in our perception of the world. In that the book succeeds in revelations that might seem counter-intuitive to begin with, but I am scratching my head as to why I didn't rate it higher. It's interesting but shallow? I don't even know if shallow is the correct word but I did not walk away much intellectually richer for it, though neither do I regret reading it. This is a strange experience for me.
