LLMs can mimic individuals using socio-economic data

Researchers have developed a method to create detailed individual-level digital twins of respondents using socio-economic microdata. These twins, built from existing heterogeneous panel data, can accurately mimic individual responses across various LLMs and information depths. The study found that twin quality improves with more data, but with diminishing returns past a certain point, and suggests that constructing these twins is now more dependent on item volume and model selection than data design.
