Rise and fall of the (social) group

This article maps the rise and fall of the idea of a (social) group across medicine in the context of contemporary analyses in psychology and sociology. This history shows the early 20th century emergence and growth of group medicine, group therapy and group comparisons. In recent decades, however, the idea that groups constituted the basic units of society has been replaced with the emergence of populations and systems that offer a more virtual and abstract context for individual relationships. This has implications for explanation itself as the demise of groups has changed the epistemological ground-rules for understanding identity formation and social change.
