Not quite a book, but you might find the materials for this MIT course on Game Theory and Social Behavior insightful: http://ocw.mit.edu/courses/economics/14-11-insights-from-gam...

"We will apply insights from game theory to explain human social behavior, focusing on novel applications which have heretofore been the realm of psychologists and philosophers—for example, why people speak indirectly, in what sense beauty is socially constructed, and where our moral intuitions come from—and eschewing traditional economic applications such as industrial organization or auctions."

I learned about signalling theory in this course, among other insights into why society acts the way it does.

Thanks. I occasionally follow news from complexity theory and there are many exciting findings. But there are so many hidden gems I could not find out till I learn some key words to make my search meaningful to the search engines.
