Is Doing Good Good Enough? A Motivation, Action, Sacrifice, and Temptation (MAST) View of Moral Praiseworthiness.

Abstract

We present the Motivation, Action, Sacrifice, and Temptation (MAST) view of moral praiseworthiness and evaluate four components shaping judgments of an actor's morality: (a) How did the person act? (b) Why did the person act? (c) Did the person sacrifice something when acting? and (d) Was the person tempted to avoid the sacrifice? Across multiple moral domains, we evaluate moral impressions of hypothetical actors who acted ostensibly morally under different motivational, sacrificial, and temptational conditions. Across four studies (total N > 1,200) and 150 morally relevant scenarios, all components shaped moral impressions, with motivational purity having the strongest impact. Exploring motivation more deeply via Self-Determination Theory, we found effects of internalized (vs. externalized) motivations. Broadly speaking, judges prefer actors to act automatically and in an idealized manner rather than with deliberation and effort. This work address questions that have fascinated philosophers, psychologists, and laypeople, advancing understanding of moral impression formation.
