This cutting-edge book re-imagines what a truly decolonial psychology could look like. It explores questions of what counts as psychological knowledge and whose knowledge is valid, and who controls the production of knowledge in psychology. This book builds on the expanding knowledge base in decolonial psychology to meaningfully address the varied social and psychological trajectories of decolonization and liberation. Featuring a wide range of international contributors, this book is grounded in an ethic of inclusion and includes contributions from researchers as well as contributions from those who engage in decolonial work outside of academia. It considers how the discipline of psychology could be transformed and how it can embrace a decolonial resistance with ideas about justice, freedom, and liberation. Drawing together a variety of expertise and ways of knowing that centers psychological research from the Global South, this book explores how we can decolonize the field and curriculum of psychology, imagining new future possibilities for the discipline. Accessibly and compellingly written, this will be essential reading for students and researchers interested in decolonizing psychology. It will be especially relevant for upper-level undergraduate and postgraduate students of cultural psychology, social psychology, and community psychology, as well as researchers, psychologists, and activists working with marginalized communities looking for ways to produce socially just knowledge.
