Drawing on preliminary research about the spread of mis- and disinformation across Asian diasporic communities, we advocate for qualitative research methodologies that can better examine historical, transnational, multilingual, and intergenerational information networks. Using examples of case studies from Vietnam, Taiwan, China, and India, we discuss research themes and challenges including legacies of multiple imperialisms, nationalisms, and geopolitical tensions as root causes of mis- and disinformation; difficulties in data collection due to private and closed information networks, language translation and interpretation; and transnational dimensions of information infrastructures and media platforms. This commentary introduces key concepts driven by methodological approaches to better study diasporic information networks beyond the dominance of Anglocentrism in existing mis- and disinformation studies.
