Memetics

Memetics is an interdisciplinary field that analyzes how ideas, behaviors, and cultural information propagate and evolve within populations by treating the idea as a replicable unit of transmission, or meme. A meme, in this framework, is any element of culture that can be copied and adapted, such as a phrase, image, ritual, or pattern of behavior.

The concept was popularized by biologist Richard Dawkins in The Selfish Gene (1976), where he draws an analogy between genes and cultural units. Memes spread through imitation, communication, and social learning, and they can change as they pass from person to person. In memetic theory, ideas compete for attention and retention, with success determined by factors that influence transmissibility, appeal, and compatibility with existing beliefs or practices.

Memetic study encompasses the mechanisms of replication, variation, and selection, with researchers examining how memes mutate, spread, and persist. It intersects with cultural evolution, psychology, anthropology, and media studies, and has been applied to areas such as marketing, political messaging, and the analysis of online cultures. Internet memes, in particular, have provided a visible and rapid example of memetic transmission, illustrating how cultural units can diversify and morph across platforms.

Critics argue that the meme concept can be ambiguously defined, difficult to measure, and prone to circular reasoning. Some scholars prefer broader frameworks of cultural evolution that emphasize information processing and social context without reducing culture to discrete memes. Nevertheless, memetics remains a commonly referenced toolbox for describing and modeling the spread of ideas in a connected world.
