At a time when children and young people’s involvement in research is increasingly the norm, this article reflects on the importance of a well-reasoned and transparent justification for their inclusion or exclusion. It explores the dilemma of a researcher’s ethical obligation to protect children and young people from harm and at the same time respect their autonomy as social actors and independent rights holders to participate in research of relevance to their lives.

The article takes the debate beyond a call for assessing harm and benefit to providing a strategy for conducting such an assessment at the point of research design.
