Our social identities intersect in ways that shape how we perceive the world, and how the world perceives us.
The concept of intersectionality was coined in 1989 by legal scholar Kimberle Crenshaw. Before then, many people viewed social identity as a single distinct quality. Intersectionality is the theory that every individual has multiple social identities that intersect. It is the intersections of these identities that shape both how we perceive the world, and how the world perceives us.
