This pathbreaking book is a must-read for any scientist who is interested in formulating and
testing hypotheses about the social world. This includes political scientists sociologists
historians geographers and anthropologists. The book is clever and funny and guides you
through the tangle of problems that confront empirical research in social science. I wish I had
had it years ago.--James Robinson Harvard University Interesting and unusual this is an
econometrics book with attitude. It offers real answers and suggestions to problems faced daily
by those engaged in the analysis of economic data. I will recommend it to my students.--Guido
Imbens Harvard University A well-written and very quirky take on econometric practice.--Orley
Ashenfelter Princeton University
