The study of ideas, behaviors, or styles that spread from person to person within a culture—the "genes" of culture, known as memes. Proposed by Richard Dawkins, it suggests that memes (like catchy tunes, fashion trends, religious beliefs, or slang) evolve through a process of variation, competition, and replication, using human minds as hosts. Success depends on "fitness" factors like simplicity, emotional resonance, and utility. Memetic theory is used to analyze everything from viral marketing and conspiracy theories to the evolution of religions and political ideologies.
Example: The rapid, global spread of the "Ice Bucket Challenge" is a textbook case of Memetic Theory. The meme (a specific behavior: dumping ice water, filming it, nominating others) had high fitness: it was simple, tied to a cause (ALS awareness), evoked strong emotions (fun, sympathy), and had a built-in replication mechanism (nominations). It outcompeted other charitable appeals and mutated into countless local variations.
