Before Scott published his book, the dominant model for understanding participation in authoritarian societies did not extend far beyond institutional and client-patron models. Scott breaks away from this mode and demonstrates how ordinary, powerless people in repressive societies can still manage to influence policies, through such actions as sabotage, foot-dragging, and gossip. This model makes it much easier to understand, for example, how China reformed its agricultural system (although this book is about a Malaysian village, it is easily applied to most any country one wishes to study).
Essential reading for political scientists and sociologists alike. After reading this book, you will have a whole different view of how change is affected, and a more sophisticated frame of analysis.
