Memetic jamming (or semiotic jamming, semiotic/memetic interference) refers to a situation where semantic noise interferes with ability for accurate information to be accessed about some entity or concept. For instance, if the internet is flooded with derivative fanfics of a work, it may make it harder to extract an accurate LLM simulation of the original work. Memetic jamming can happen inadvertantly or as part of an intentional attack.
