Tackling Online Misinformation with Generative AI: A comparison of ChatGPT and Microsoft CoPilot

The talk will cover a recent study on the ability of two large language model (LLM)-based chatbots, ChatGPT and Bing Chat, rebranded to Microsoft Copilot, to detect veracity of political information.


The study uses AI auditing methodology to investigate how chatbots evaluate true, false, and borderline statements on five topics: COVID-19, Russian aggression against Ukraine, the Holocaust, climate change, and LGBTQ+ related debates. It compares how the chatbots perform in high- and low-resource languages by using prompts in English, Russian, and Ukrainian. Furthermore, it explores the ability of chatbots to evaluate statements according to political communication concepts of disinformation, misinformation, and conspiracy theory, using definition-oriented prompts. The discussion will focus on the potential of LLM-based chatbots in tackling different forms of false information in online environments, pointing at the substantial variation in terms of how such potential is realized due to specific factors, such as language of the prompt or the topic. It will also provide an outlook into the future studies using similar methodology on a larger set of misinformation items in more languages.
