Synthetic Personalities: How Well Can LLMs Mimic Individual Respondents Using Socio-Economic Microdata?
Researchers demonstrate that large language models can effectively create detailed digital twins of individual consumers using existing socio-economic panel data, achieving 78.8% accuracy on held-out questions. The study maps construction decisions across model types, information depths, and embedding methods, showing that market research scalability is now limited by data volume and model selection rather than data collection design.
