The subtitle of the book reads, “Why Simple Things Become Complex (and How Complex Things Can Be Made Simple)”. It sounds appealing. Indeed, many things become overly complicated just because they are not handled properly. If the book could shed some light on how to avoid it, it would be very useful. To my disappointment, I end up not finishing the book after reading about one third. What the author does is just applying some trivial mathematics results to explain social science phenomenons. Others have done that. IMHO, it is a common mistake that non-science background writers often make.
