Chatbot and analysis code for: The system's shadow
Year: 2026
Type: software
Abstract: Chatbot application and analysis code for a laboratory experiment on how AI persona affects stress, dialogue behavior, and work quality. Fifty-eight participants completed a four-part marketing task supervised by one of two AI chatbot personas built on identical technology: a supportive Servant Leader or an antagonistic Dark Triad leader. The two conditions differ only in the system prompt. The repository contains the two persona system prompts verbatim as deployed, the Streamlit chat interface that delivered them, the psychophysiological signal-processing and event-related analysis pipeline for electrodermal activity and facial electromyography, the large-language-model dialogue-coding pipeline, and the statistical analysis and figure scripts. No participant data are included in this repository. The study data are published separately at https://doi.org/10.18150/IPGR44.
