Morality has two key features: moral judgments are not solely determined by what your group thinks, and moral judgments are often applied to members of other groups as well as your own group. Cooperative motives do not explain how young children reject unfairness, and assert moral obligations, both inside and outside their groups. Resistance and experience with conflicts, alongside cooperation, is key to the emergence and development of moral obligation.

Team reasoning is the idea that we can think as a ‘we’ and this can solve some coordination dilemmas, such as Hi-Lo. However, team reasoning can only solve the dilemmas it is intended to solve if the conditions for team reasoning warrant the belief that others will also perform team reasoning and these conditions cannot render team reasoning otiose. In this paper, I will supplement the theory of team reasoning by explaining how agency transformation also involves a change in the (...) normative attitude. To do this, I will use the theory of affordances, which is the idea that the environment provides ways to interact with it. I will argue that when a person perceives as a group member, she associates herself and the other members with the group’s mosaic of affordances. This triggers a feeling of joint ownership of the agency. It is the feeling that it is up to us to deal with the situation, so we feel entitled to demand each other to cooperate. It warrants the belief that others are team-reasoners without rendering team reasoning otiose. This means that the agency transformation (from I to we) involves a change in the normative attitude.

Ownership is universal and ubiquitous in human societies, yet the psychology underpinning ownership intuitions is generally not described in a coherent and computationally tractable manner. Ownership intuitions are commonly assumed to derive from culturally transmitted social norms, or from a mentally represented implicit theory. While the social norms account is entirelyad hoc, the mental theory requires prior assumptions about possession and ownership that must be explained. Here I propose such an explanation, arguing that the intuitions result from the interaction of (...) two cognitive systems. One of these handles competitive interactions for the possession of resources observed in many species including humans. The other handles mutually beneficial cooperation between agents, as observed in communal sharing, collective action and trade. Together, these systems attend to specific cues in the environment, and produce definite intuitions such as “this is hers,” “that is not mine.” This computational model provides an explanation for ownership intuitions, not just in straightforward cases of property, but also in disputed ownership (squatters, indigenous rights), historical changes (abolition of slavery), as well as apparently marginal cases, such as the questions, whether people own their seats on the bus, or their places in a queue, and how people understand “cultural appropriation” and slavery. In contrast to some previous theories, the model is empirically testable and free ofad hocstipulations. (shrink)
