In the United States, constructivist views of knowledge are closely linked to such progressive movements as post-colonialism and multiculturalism because they supply the philosophical resources with which to protect oppressed cultures from the charge of holding false or unjustified views.
Even on purely political grounds, however, it is difficult to understand how this could have come to seem a good application of constructivist thought: for if the powerful can’t criticize the oppressed, because the central epistemological categories are inexorably tied to particular perspectives, it also follows that the oppressed can’t criticize the powerful.
