LLMs are trained to produce open-ended responses 📝, but most survey items require closed-ended responses instead 📊
This Wed 11:00–12:30 at #ESRA25, I'll discuss the large impact that Answer Production Methods have on prediction results + share recommendations for methods and parameters. 👈

Really excited to also present this work at #IC2S2 next week in Norrköping! 🎉 I'd love to discuss how to produce LLM survey responses at my poster on Wed at 13:30 (Poster Session 2, Poster ID 68) 📊

🤔 Ever wondered how the way you write a persona prompt affects how well an LLM simulates people?
In our #EMNLP2025 paper, we find that using interview-style persona prompts makes LLM social simulations less biased and more aligned with human opinions.

Abstract
Large Language Models (LLMs) have the potential to revolutionize the social sciences—for example, by accelerating content analysis or enabling realistic social simulations. In this workshop, I will discuss how LLMs can be applied and audited for social science applications, including the generation of synthetic survey responses and content analysis. I will also address how biases in LLMs can hinder these applications and explore ways to better surface and understand these biases. Finally, I will present a hands-on use case demonstrating how LLMs can be guided using demographic personas for both content analysis and simulated surveys.
Presenter(s)
Indira Sen is a Junior Faculty member at the University of Mannheim’s Business School in the Chair of Data Science for the Social and Economic Sciences. Her work lies at the intersection of NLP and Computational Social Science, specifically in developing and evaluating representative and equitable language technology, including Large Language Models.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:oizrkjzyr6vekl76tjctghcl/bafkreigj6rty2hy4hgawqzq34a24si45dxzutezuphif3hprnl5amxldoy@jpeg)

LLMs can generate synthetic survey responses, e.g. for imputation, but how reliable are they? 📋
At #IC2S2, I'll be sharing our research on the robustness of AI-generated responses to perturbations and if they mirror human survey biases. 🤖
