“Poor brain development” in the global South? Challenging the science of early childhood interventions

Global Early Childhood Development (ECD)—an applied field with the aim to improve the “brain structure and function” of future generations in the global South—has moved to the center of international development. Global ECD rests heavily on evidence claims about widespread cognitive, social, and emotional deficits in the global South and the benefits of changing parenting practices in order to optimize early childhood development. We challenge these claims on the grounds that the leading ECD literature excludes research from anthropology, cultural psychology, and related fields that could provide crucial insights about childrearing and children's development in the targeted communities. We encourage anthropologists and other scholars with ethnographic expertise on childhood to critically engage with global ECD. To facilitate such an endeavor, this article sketches the history, scientific claims, and interventions of global ECD, points out the critical potential of ethnographic research, and suggests strategies to make ethnography more relevant.
