A new arXiv preprint develops a formal mathematical framework to analyze how widespread LLM-assisted writing may reduce population-level linguistic diversity, a phenomenon the authors term 'linguistic monoculture.' The paper models authors and LLMs as distributions over linguistic features and analyzes three interaction mechanisms—fixed shared models, recursively updated shared models, and personalized models—characterizing equilibria and convergence rates for each. A key finding is that individually rational authors may over-conform relative to the social optimum because they do not internalize the value of their own distinctiveness, creating a negative externality. The 'price of monoculture' can grow without bound when distinctiveness dominates authenticity in the utility model.
