discuss procedures regarding two morally mandated issues, abortion and capital punishment. Those in attitudinally heterogeneous groups demonstrated the least amount of goodwill towards other group members, the least amount of cooperation, and the most tension/defensiveness. Furthermore, individuals discussing a morally mandated issue were less likely to reach a consensus compared to those discussing non-moral issues. Intersections with other fields Sociological applications Some research shows that people tend to self-segregate based on moral and political views, exaggerate the magnitude of moral disagreements across political divides, and avoid exposure to the opinions of those with opposing political views. Normative implications Researchers have begun to debate the implications (if any) moral psychology research has for other subfields of ethics such as normative ethics and meta-ethics. For example Peter Singer, citing Haidt's work on social intuitionism and Greene's dual process theory, presented an "evolutionary debunking argument" suggesting that the normative force of our moral intuitions is undermined by their being the "biological residue of our evolutionary history." John Doris discusses the way in which social psychological experiments—such as the Stanford prison experiments involving the idea of situationism—call into question a key component in virtue ethics: the idea that individuals have a single, environment-independent moral character. As a further example, Shaun Nichols (2004) examines how empirical data on psychopathology suggests that moral rationalism is false. Additionally, research in moral psychology is being used to inform debates in applied ethics around moral enhancement. Robotics and artificial intelligence At the intersection of moral psychology and machine ethics, researchers have begun to study people's views regarding the potentially ethically significant decisions that will be made by self-driving cars.
