"Michael C. Moynihan reviewing the book for The Wall Street Journal stated that the writing style is similar to that of Freakonomics."
Ouch. If someone said that about a book I'd written, I would simply move to a forest and never write a single word again. Quite the damning review.

My comment wasn't about vulgarisation - it was about Freakonomics' loose approach to rigour and consequent debunking of, IIRC, most of the book.
A quick search for "Bruce Bueno de Mesquita" throws up similar debunkings[0] and yeah, I'll not be reading his books after seeing how grandiose his claims are compared with the actuality of what happened.
