Shattered assumptions theory
In social psychology, shattered assumptions theory proposes that experiencing traumatic events can change how victims and survivors view themselves and the world. Specifically, the theory – published by Ronnie Janoff-Bulman in 1992 – concerns the effect that negative events have on three inherent assumptions: overall benevolence of the world, meaningfulness of the world, and self worth.
