# LLM辅助语言使用中的语言单一文化现象研究

## AI 点评

> 这篇论文用数学语言精准刻画了一个我们隐约感受到但未曾被系统论证的问题——LLM辅助写作正在悄悄抹平语言多样性。它不仅定义清晰，还给出了不同交互机制下的收敛与多样性保留条件，尤其是对从众行为社会成本的揭示发人深省。对于AI产品经理和语言政策研究者来说，是绕过炒作直击本质的必读文献。

## 速览

本文研究大规模语言模型（LLM）辅助写作导致的语言单一化问题，即语言单一文化。作者建立数学模型，将作者和LLM表示为语言特征分布，分析三种交互机制：固定共享模型、递归反馈模型和个性化模型。研究发现，共享模型促使作者趋同，递归反馈改变共同规范但不缩小个体差异，个性化可保持语言多样性。进一步将从众行为内生化，发现个体理性选择会导致过度从众，产生负外部性，造成语言单一文化的代价。模拟实验验证了不同机制对长期多样性的影响。

## 关键点

- 提出“语言单一文化”概念，定义LLM辅助写作导致的语言形式趋同现象
- 建立包含作者-LLM共同演化的数学模型，分析三种交互机制对语言多样性的影响
- 揭示从众行为的社会成本：个体理性导致过度从众，产生负外部性
- 通过模拟实验展示不同机制下的长期语言多样性结果

## 全文

Writing and communication are increasingly mediated by large language models (LLMs) that are being used to draft, revise and polish text. Although such assistance can improve clarity and help authors meet institutional expectations, widespread reliance on shared models may reduce population-level variation in linguistic form, a phenomenon we refer to as linguistic monoculture. We develop a mathematical framework in which authors and LLMs are represented as distributions over linguistic features and coevolve through repeated interaction. We analyze three interaction mechanisms: a shared model with a fixed linguistic distribution, a shared model recursively updated from author outputs, and personalized models updated through author-specific and population-level feedback. We characterize the resulting equilibria and convergence rates, showing that, shared models can drive authors toward a common norm, recursive feedback relocates the shared norm without altering pairwise spread under common conformity, and personalization can preserve a family of distinct author-model equilibria with nonzero linguistic diversity. We then endogenize conformity as a strategic choice trading off private benefits from clarity, legibility, and perceived fluency against distinctive style. Within this utility model, individually rational authors may conform more than is socially optimal because they do not internalize the value their distinctiveness provides to others, creating a negative externality and a price of monoculture that is finite for each fixed instance but can grow without bound when distinctiveness dominates authenticity. Synthetic simulations illustrate how fixed shared assistance, recursive feedback, and personalization produce different long-run diversity outcomes.
