Mapping moral pluralism in behavioural spillovers : a cross-disciplinary account of the multiple ways in which we engage in moral valuing

In this article, we reflect critically on how moral actions are categorised in some recent studies on moral spillovers. Based on classic concepts from moral philosophy, we present a framework to categorise moral actions. We argue that with such finer gradation of the moral values, associated behaviour is better understood, and this understanding helps to identify the conditions under which moral licensing takes place. We illustrate our argument with examples from the literature on proenvironmental behaviours. Moral spillovers are frequently observed in this behavioural domain and to understand what causes their occurrence is highly (policy) relevant if we wish to promote sustainable behaviour.
