The book is mostly "garbage in, garbage out" analysis where an economist with the most superficial knowledge of several topics will do his own research and torture the numbers to say whatever. I give it one extra star because it does deliver on its promise of providing riddles and stories to last a thousand cocktail parties - unless those parties happen to have a specialist to debunk your freaky/rogue claims, but that rarely happens (unfortunately).

If you know someone who likes to feel smart, who takes pleasure in a contrarian position, most likely holds individualistic and libertarian values, and is a bit of a smug that loves to gotcha people around, they'll certainly eat this book like it's hot cake. Of course the cover brings a recommendation by Malcom Gladwell himself, the forefather of fake expertise.
