Eun Cheol Choi Researches Misinformation and AI's Role in Social Networks
Eun Cheol Choi, a Ph.D. candidate in Communication at the University of Southern California (USC), is conducting research on misinformation and social networks. His work explores how the structure of individuals' social networks influences their belief in and sharing of misinformation. Additionally, Choi investigates the extent to which AI systems can accurately replicate human beliefs, attitudes, and social structures when used as proxies for human research participants. He has also developed tools that assist fact-checkers in identifying recurring misinformation using large language models. His research, which combines communication and computer science, has been published in the journal Social Networks and presented at various conferences, including ICML, ICWSM, and the ACM Web Conference. Initial findings from a U.S. adult survey suggest that susceptibility to misinformation is shaped by both individual attitudes and social network structures. Subsequent analysis of large language models (LLMs) simulat...
