Research involving young people is a challenging process that requires managing relationships with diverse individuals and groups, including the young participants and their various gatekeepers. While it is normally assumed that the researcher is in overall control of their research, by using a Foucauldian conception of 'power as effects' that operate in the form of relations and through discourse as the articulation of norms, this paper discusses how, in practice, the researcher can lose control over their research and so be forced into making substantial compromises concerning the nature and extent of the data they can collect. I do this by reflecting on my experience of conducting research involving UK secondary school students using online data collection methods during the COVID-19 pandemic. I identify several factors that generated power effects which influenced the conduct of the research, including: an ethics review that relied on a simplistic discourse concerning young participants' (in)competence; my own self-regulation of my conduct in respect of 'ethical' research; my 'positionality' in the field; and a researcher's general dependence on participants and gatekeepers to complete their research. I conclude by reflecting on how these factors may impact upon the conditions for viable social research involving young people.
