A detailed exploration and integration of behavior change research into a unifying multi-level fractal theory, Intentional Change Theory (ICT), showing the science behind sustained, desired change at the individual, dyadic, team, organizational, community, and country levels. Change is constant and ever-present in everyday life. Yet sustained, desired change is much harder to grasp. Bringing together 50 years of research into behavior change, The Science of Change explores Intentional Change Theory (ICT) and highlights how the model can be used to understand and support lasting change. In this book, Richard E. Boyatzis presents a unifying theory for lasting change with an examination of each phase and principle in this multi-level, fractal theory and provides examples of sustained, desired change at the individual, dyadic, team, organization, community, and country levels. The five phases of ICT describe a cycle of change. It starts with a vision of an ideal self, examines the real sel
