Abstract

Moral norms are fundamental for virtually all social interactions, including cooperation. Moral norms develop and change, but the mechanisms underlying when, and how, such changes occur are not well-described by theories of moral psychology. We tested, and confirmed, the hypothesis that the commonness of an observed behavior consistently influences its moral status, which we refer to as the common is moral (CIM) heuristic. In 9 experiments, we used an experimental model of dynamic social interaction that manipulated the commonness of altruistic and selfish behaviors to examine the change of peoples’ moral judgments. We found that both altruistic and selfish behaviors were judged as more moral, and less deserving of punishment, when common than when rare, which could be explained by a classical formal model (social impact theory) of behavioral conformity. Furthermore, judgments of common versus rare behaviors were faster, indicating that they were computationally more efficient. Finally, we used agent-based computer simulations to investigate the endogenous population dynamics predicted to emerge if individuals use the CIM heuristic, and found that the CIM heuristic is sufficient for producing 2 hallmarks of real moral norms; stability and sudden changes. Our results demonstrate that commonness shapes our moral psychology through mechanisms similar to behavioral conformity with wide implications for understanding the stability and change of moral norms.

Moral Enhancement and Moral Freedom: A Critical Analysis

The debate about moral neuroenhancement has taken off in the past decade. Although the term admits of several definitions, the debate primarily focuses on the ways in which human enhancement technologies could be used to ensure greater moral conformity, i.e. the conformity of human behaviour with moral norms. Imagine you have just witnessed a road rage incident. An irate driver, stuck in a traffic jam, jumped out of his car and proceeded to abuse the driver in the car behind him. We could all agree that this contravenes a moral norm. And we may well agree that the proximate cause of his outburst was a particular pattern of activity in the rage circuit of his brain. What if we could intervene in that circuit and prevent him from abusing his fellow motorists? Should we do it?

Proponents of moral neuroenhancement think we should — though they typically focus on much higher stakes scenarios. A popular criticism of their project has emerged. This criticism holds that trying to ensure moral conformity comes at the price of moral freedom. If our brains are prodded, poked and tweaked so that we never do the wrong thing, then we lose the ‘freedom to fall’ — i.e. the freedom to do evil. That would be a great shame. The freedom to do the wrong thing is, in itself, an important human value. We would lose it in the pursuit of greater moral conformity.
