Positioning theory is a theory in social psychology that characterizes interactions between individuals. "Position" can be defined as an alterable collection of beliefs of an individual with regards to their rights, duties, and obligations. "Positioning" is the mechanism through which roles are assigned or denied, either to oneself or others. The theory describes malleable roles and storylines that determine the boundaries of future acts and the meanings of what people say and do. The theory expands upon the work of psychologist Lev Vygotsky, especially his theory of zone of proximal development (ZPD). It emphasizes the interdependence of positions, speech and other acts, and storylines that arise from them; a change in any one aspect affects the other two. The theory provides a framework to understand a person's specific behavior by considering social, individual, and moral factors.
There are three orders of positioning based on how positions are assumed: first-, second- and third-order positioning. Positioning can also be classified into various types depending on the specifics of the situation; these include self, other, tacit, intentional, interactive, reflexive, moral, personal, indirect, and malignant positioning. Positioning theory originated in the 1990s from Positioning: the discursive production of selves, which looked to solve a problem that arose "out of a discussion about the problems inherent in the use of the concept of role in developing a social psychology of selfhood".[1] Since its inception, Positioning theory has been developed further with contributions from Bronwyn Davies, Rom Harré, Luk Van Langenhove, and Fathali Moghaddam. The theory has provided a structure for social discourse analysis, and it has been used to study various social situations. Its application has extended into fields such as education, anthropology, communication, and political science.
