The sociology of knowledge is the study of the relationship between human thought and the social context within which it arises, and of the effects prevailing ideas have on societies. It is not a specialized area of sociology but instead deals with broad fundamental questions about the extent and limits of social influences on individual's lives and the social-cultural basics of our knowledge about the world. Complementary to the sociology of knowledge is the sociology of ignorance, including the study of nescience, ignorance, knowledge gaps, or non-knowledge as inherent features of knowledge making.
