n. The belief that changes in one culture are caused by diffusion of ideas from another, especially the West.

Usage examples of "diffusionism".

Currently there is a revival in diffusionism, a popular scientific concept of the 1920s which asserted that many of the puzzling artifacts and ancient constructions found throughout the world were the products of a single worldwide culture.

Admitting to an open mind on diffusionism was a oneway ticket to oblivion for a mainstream archaeologist.
