Constructivism's basic premise - that individuals and groups are shaped by their world but can also change it - may seem intuitively true. Yet this process-oriented approach can be more difficult to apply than structural or rational choice frameworks. Based on their own experiences and exemplars from the IR literature, well-known authors Audie Klotz and Cecelia Lynch lay out concepts and tools for anyone seeking to apply the constructivist approach in research. Written in jargon-free prose and relevant across the social sciences, this book is essential for anyone trying to sort out appropriate methods for empirical research.
