Social constructionism
Social constructionism or the social construction of reality (also social concept) is a theory of knowledge in sociology and communication theory that examines the development of jointly constructed understandings of the world that form the basis for shared assumptions about reality. The theory centers on the notions that human beings rationalize their experience by creating models of the social world and share and reify these models through language.
Definition
A social construct or construction concerns the meaning, notion, or connotation placed on an object or event by a society, and adopted by the inhabitants of that society with respect to how they view or deal with the object or event. In that respect, a social construct as an idea would be widely accepted as natural by the society, but may or may not represent a reality shared by those outside the society, and would be an "invention or artifice of that society."
A major focus of social constructionism is to uncover the ways in which individuals and groups participate in the construction of their perceived social reality. It involves looking at the ways social phenomena are created, institutionalized, known, and made into tradition by humans.
