In this episode, which forms part of a series on ethics in behavioural science research, we talk with Sandro Ambuehl from the University of Zürich about his paper “An Offer You Can’t Refuse? Incentives Change How We Inform Ourselves and What We Believe”. To investigate how economic incentives may skew information gathering and beliefs about what a transaction entails, thus affecting the quality of decisions taken by subjects, he presents a model of costly information acquisition in conjunction with behavioural experiments, one of which includes the ingestion of insects in exchange for money. Tune in for a discussion centred around the project’s design, its ethical and logistical considerations, and on the ethics of incentivising subjects in economic experiments more generally.
