The Moral Punishment Instinct
Across time and cultures, ranging from ancient hunter-gatherers, to holy scriptures, to contemporary courts of law, it has been common for people to punish offenders. Furthermore, punishment is not restricted to criminal offenders but emerges in all spheres of social life. Why is punishment so ubiquitous? Punishment also occurs among nonhuman animals for which one can question their sense of morality. Apparently, there is something specific about punishment that warrants a more focused discussion. This work proposes that people possess a moral punishment instinct, that is, a hard-wired tendency to aggress against those who violate the norms of the group.
