Migration studies is the multi- and interdisciplinary field devoted to examining and explaining causes, experiences, and impacts of human mobility. Researchers studying migration face a plenitude of ethical challenges, especially in studies on or with “vulnerable populations”—people that are in dire legal, economic, or psychological circumstances, or of young age. However, there are more general normative imperatives deriving from the field’s traditionally close relationship to the nation-state system and the international refugee regime. Because migration studies is an academic field with direct societal relevance, its research findings often have the potential to influence policy decision-making, which renders migration scholars in a powerful position to exert influence on how societal resources are distributed. Although these circumstances clearly call for a strong ethical framework throughout the research process, from proposal writing to dissemination, normative considerations have only been observed in some parts of the field. Ethical considerations are most pronounced in methodological inquiries, and issues of representation and labelling as well as the researcher’s positionality have also received significant attention. Nonetheless, many ethical considerations remain generally implicit rather than explicit. However, a growing “critical” and “reflexive” migration scholarship has been increasingly calling into question the close relationship between academia and the nation-state and pointing at the pitfalls of unreflexive scholarship. The focus of these migration scholars on power inequalities in the production and dissemination of knowledge, as well as on the effects of policy-oriented research, can be read as an ethical imperative for good scholarship.
