Narrativism is a philosophy that states that the truth claims of a conceptual framework, belief system, or religion are not so much assertions about the nature of reality but stories intended to produce certain desired results, and whether those stories are true is irrelevant as long as they achieve the desired outcome.
This philosophy is central to Atavism and explains why Atavists keep setting up isolated primitive societies with elaborately crafted mythologies. The Bright Way and most branches of Neoshamanism reject Narrativism, saying that truth exists and knowing the truth is important.
