Positionality initially emerged from critiques of omniscient, unmarked researchers producing supposedly value‐free, impartial research. Beginning from the premise that knowledge is partial, situated, and power‐laden, positionality highlights how people, including researchers, are differently positioned in hierarchies of power and privilege and thus come to know and interpret the world from different social locations. The researcher's positionality shapes their research, inhibiting or enabling certain research insights, and mediates the research process, including relations with the people, places, and materials of the research project. Positionality is also a relational concept: the researched are knowledgeable agents and as such they and the researcher both structure the research encounter and construct “the data.” Positionality has been refined and adapted over time. The theoretical, conceptual, and empirical interventions around intersectionality and embodiment have been especially significant.
