Hwanseok Song

Ph.D., Cornell University M.A., Johns Hopkins University B.A., Yonsei University Professor Song's research focuses examines social cognitive processes underlying risk, science, and environmental communication, with a particular focus on how people’s judgments about others such as public authorities and fellow citizens further shape their communicative practices, attitudes and behavior. Using experimental and survey methods, he has examined the nature of judgments such as trust, fairness, justice, and norm violation, as well as how these judgments shape responses to risk, authorities, and fellow citizens. He teaches courses on risk communication, persuasion, and judgment and decision making. Select Publications Song, H. & Adu Gyamfi, P. (2025).
