Misinformation Studies is an interdisciplinary field that maps, analyses, and explains how false or misleading information spreads in society, particularly through digital media, social networks, and traditional outlets. This field brings together media studies, journalism, data analysis, sociology, psychology, and policy research to find out why misinformation is created, how it spreads, who it affects, and what can be done to reduce its harm. In Bangladesh and across South Asia, this field also examines cross‑border misinformation, hate speech, influence operations, synthetic media, and the role of AI in amplifying or countering false narratives.
