Critical social theory is a group of approaches, most prominently including critical race theory, critical legal theory, and critical disability studies that comes from theorist at the Frankfurt School in the 1930s who theories that the convergence of capitalism, bureaucracy and science was restricting the development of a critical consciousness and ability to critique societal functioning. The heart of more modern critical social theory - along with post-Marxist, post-structuralist, postmodernists, and post-positive theorizing - is the idea of problematizing issues including the terms we are using, or the assumptions given to us, understanding society and culture as something much more dynamic than can be captured purely quantitatively, and a focus on the linking of theory and liberatory praxis.
