Eli Bendersky's website Secondary title: A rogue economist explores the hidden side of everything.
Freakonomics is just the book any rational would love. What can be more fun than taking real life itself, and dissecting it to small details using financial and statistical methods, reaching interesting conclusions about the selfish motivations of people driving inter-personal relationships.
This is one of the major topics the book deals with. Another is a thorough application of statistical analysis to curious data sets - like crime in the US in the 90s, school education data to understand what makes good and bad students, statistics of parenting, and how peoples' names are (or aren't) correlated with their success in life. Everything written in a very light-weight and entertaining style.
There's a tiny feeling of "pop" about this book - almost as if it focuses on topics which sell best because of their "curiosity factor". However, the authors also display a rather solid scientific outlook on things, which I liked. There's an emphasis on correct analysis of data, with some clues to what factors only seem important, and how to separate the wheat from the chaff. All in all, the book is written with a scientific point of view - which makes it lots of fun to read.
In one word - recommended. In two words - highly recommended. A truly enjoyable book.
