Types

  • Expansion diffusion: an innovation or idea that develops in a source area and remains strong there, while also spreading outward to other areas.
  • Relocation diffusion: an idea or innovation that migrates into new areas, leaving behind its origin or source of the cultural trait.
  • Hierarchical diffusion: an idea or innovation that spreads by moving from larger to smaller places, often with little regard to the distance between places, and often influenced by social elites.
  • Contagious diffusion: an idea or innovation based on person-to-person contact within a given population.

Mechanisms

Inter-cultural diffusion can happen in many ways. Migrating populations

Human migration is physical movement by humans from one area to another, sometimes over long distances or in large groups. Historically this movement was nomadic, often causing significant conflict with the indigenous population and their displacement or cultural assimilation. Only a few nomadic...

, soldiers, diplomats, slaves, and hired artisans. Technology diffusion has often occurred by one society luring skilled scientists or workers by payments or other inducement. Trans-cultural marriages between two neighboring or interspersed cultures have also contributed. Among literate societies, diffusion can happen through letters or books (and, in modern times, through other media as well).

There are three categories of diffusion mechanisms:
  • Direct diffusion is when two cultures are very close to each other, resulting in intermarriage, trade, and even warfare. An example of direct diffusion is between the United States

  • Forced diffusion occurs when one culture subjugates (conquers or enslaves) another culture and forces its own customs on the conquered people. An example would be the forced Christianization

  • Indirect diffusion happens when traits are passed from one culture through a middleman to another culture, without the first and final cultures ever being in direct contact. An example could be the presence of Mexican food in Canada, since a large territory (the United States) lies in between.


Direct diffusion is very common in ancient times, when small groups, or bands, of humans lived in adjoining settlements. Indirect diffusion is very common in today's world, because of the mass media and the invention of the Internet

Theories

The many models that have been proposed for inter-cultural diffusion are

  • Culture circles diffusionism (Kulturkreise)—the theory that cultures originated from a small number of cultures.

  • Mallory's "Kulturkugel" (a non-existent German compound meaning "culture bullet"), a term suggested by JP Mallory

     vs. gradual migration vs. diffusion. According to this model, local continuity of material culture and social organization is stronger than linguistic continuity, so that cultural contact or limited migration regularly leads to linguistic changes without affecting material culture or social organization.


A concept that has often been mentioned in this regard, which may be framed in the evolutionary diffusionism model, is that of "an idea whose time has come" — whereby a new cultural item appears almost simultaneously and independently in several widely separated places, after certain prerequisite items have diffused across the respective communities. This concept has been invoked, for example, with regard to the development of calculus

Those disputed are fueled in part by the overuse of cultural diffusion, starting in the late 19th century, as a blanket explanation for all similarities between widely dispersed cultures. The most famous proponent of this theory was Grafton Elliot Smith

 and then diffused to other places.

Diffusion theories also suffer from being inherently speculative and hard to prove or disprove; especially for relatively simple cultural items like "pyramid-shaped buildings", "solar deity", "row of standing stones", or "animal paintings in caves". After all, the act of diffusion proper is a purely mental (or at most verbal) phenomenon, that leaves no archaeological trace. Therefore, diffusion can be deduced with some certainty only when the similarities involve a relatively complex and partly arbitrary collection of items—such as a writing system, a complex myth, or a pantheon of several gods.

Another criticism that has been leveled at many diffusion proposals is the failure to explain why certain items were not diffused. For example, attempts to "explain" the New World civilizations by diffusion from Europe or Egypt should explain why basic concepts like wheeled vehicles or the potter's wheel did not cross the ocean, while writing and stone pyramids did.
