Ethics committees enjoy both a long history and a strong presence in Anglophone countries, although simultaneously their functioning provokes debate in the social research community. In this paper, I analyse selected contested issues that revolve around three questions: 1) Who do ethics committees protect, and who should they? 2) Should ethics committees protect all research participants in the same way? 3) When can ethics committees intervene in the methodology of the research project under review? Analysing these disputes is important since (...) it may help to improve the functioning of ethics committees for social research in Poland. Their number has increased significantly in the last decade, but this has not been accompanied by a broader reflection on either their functioning or the concerns associated with this kind of control.
