The paper highlights the need to discuss the norm of reciprocity in the context of basic income experiments. Considering how the norm of reciprocity is an important objection to basic income, both at a normative level, but also in empirical discussions, a case is made for considering it in basic income experiments. The paper proposes several hypotheses on basic income and reciprocity and concludes with two distinct points: the first is focused on what in fact experiments could be telling us (...) about behaviours that seem relevant to reciprocity, and how this could enhance our understanding of both basic income and the norm of reciprocity. The second point is a reflection on how our theoretical debate is shaped on ideal settings, whereas experiments take place in real-world conditions, hence non-ideal ones. This reflection might contribute to the need to reframe our theoretical account of the norm of reciprocity. (shrink)
