Since field experiments may serve as a bridge between laboratory and naturally-occurring data, the present paper aims to test to what extent individuals belonging to a group react differently to nudges conditional on the experimental context. Data from 597 individuals participating in a laboratory experiment in 2023, France, and 1292 households in a field experiment between 2022 and 2023 in Spain, allows us to estimate the average treatment effects of providing information on observed, peer and optimal use of two public goods: a hypothetical group pool, and collective-metered water from a real block of apartments. Nudging with optimal behavior is the strategy that performs better, fostering individual preservation of the public good in the lab, while it leads to a boomerang effect in the field for the low-use buildings. The effects of nudging are also conditional on the group sociodemographic composition: groups with a majority of elder members, and/or women are more prone to follow nudges in the right direction. Additionally, information that confirms the belief of other members misusing the group’s public good reverses the desired impact of nudging.
