Most recent work in moral psychology has focused on hypothetical interactions between strangers, as in so-called trolley problems. But most of our moral judgments in real-life concern individuals with whom we stand in particular social relationships: friends, family, neighbours, bosses, employees, and so on. In this talk I present a new model of relational norms that guide our ethical decision-making, with empirical data to support the theoretical framework. Normative implications for bioethics will also be discussed.
