Theory and research regarding moral motivation has focused for decades on the roles of moral reasoning and, to some extent, moral emotion. Recently, however, several models of morality have positioned identity as an additional important source of moral motivation.

Additionally, it suggests several key unanswered questions about moral identity and provides recommendations for future research
