This book offers an expert synthesis of the scholarly literature on approaches to decolonial psychology, its historical foundations, education and training, and psychological practice. From its inception, psychological science and practice in the United States has been framed predominantly by Eurocentric epistemologies. As a result, oppressed people have internalized the belief that their culture and values are inferior to those of dominant groups. Infusing a decolonial lens into psychology is one way for the field to become more inclusive and relevant to the numerical majority worldwide.
