Hyperdiffusionism refers to the theory that suggests that cultural diffusion or the spread of ideas from one culture to another occurs at an incredibly fast rate. Some synonyms for this term include accelerationism, rapidism, and turbo-diffusionism. These terms all refer to the belief that cultural exchange happens at a higher speed than previously thought. Other synonyms for hyperdiffusionism include ultradiffusionism, extreme diffusionism, and maximalist theory. All of these terms emphasize the extreme speed and potency of cultural diffusion and exchange, suggesting that cultures rapidly adopt ideas from others and change in response to them. Overall, hyperdiffusionism and its synonyms represent a deeply interesting and complex area of cultural theory and anthropological study.
