Mapping the moral maps: from alternate taxonomies to competing predictions

The Model of Moral Motives will be of great value to moral psychology, both for its conceptualization of the provide/protect distinction at different levels of analysis (intrapersonal, interpersonal, intragroup, intergroup) and for its usefulness in integrating multiple theoretical perspectives on morality. To the latter end, this commentary makes three suggestions for improvements to the model and its integration with Moral Foundations Theory: (a) clarify what the columns of the model represent, (b) modify the one-to-one mapping of moral foundations onto the cells of the model, and (c) specify testable predictions uniquely generated by the model. Possibilities for future empirical tests of competing predictions are discussed, with the long-term aim of adjudicating between different theoretical accounts of ideological differences and the moral domain.
