In this introductory chapter, we make the case that there are many aspects of our lives that are in urgent need of change and yet not changing. Powerful forces involving capital, wealth, politics, technology, religion, culture, and beliefs seem to be pushing us in directions that none of us ultimately want to go. We take this as proof that we, as people who study change, need breakthroughs in not just what we research but how we conduct research. We need new theory but also new methods. These new methods must address multiple challenges concerning the validity, reliability, generalizability, measurement, and impact of the data we collect to learn more about successful change. Finally, we overview the chapters that make up this volume and our hope that this work will propel paradigm shifts in the way we study change.
