 By way of organization, the entry starts with basics and proceeds to add subsequent layers of intricacy and detail. Researchers taking cognitive-evolutionary approaches to norms come from a wide range of disciplines, and have formulated, explored, and debated positions on a large number of different issues. In order to present a comprehensible overview of these interconnected literatures, the entry starts by laying out main contours and central tenets, the key landmarks in the conceptual space common to different theories and claims. It goes on to provide a more detailed description of the kinds of theoretical resources that researchers have employed, and identifies important dimensions along which more specific accounts of the psychology of norms have varied. It then canvasses different sources of empirical evidence that have begun to illuminate other philosophically interesting features of the capacity for norms. Finally, it ends with a discussion of the relationship between norm cognition and morality, with a few illustrations drawn from recent debates in moral theory.
