Researchers have developed a new framework called Parametric Social Identity Injection (PSII) to address the issue of social diversity collapse in large language models used for public opinion simulation. This method injects explicit demographic and value-orientation data directly into the LLM's hidden states, allowing for more controlled and nuanced identity representation than traditional prompt-based methods. Experiments using the World Values Survey demonstrated that PSII significantly enhances the fidelity and diversity of simulated public opinion across various open-source LLMs. AI
IMPACT Enhances LLM capabilities for more realistic social simulations and potentially improves survey methodologies.
