Explaining the evolution and maintenance of cooperation among unrelated individuals is one of the fundamental problems in biology and the social sciences. Recent findings suggest that altruistic punishment is an important mechanism maintaining cooperation among humans. We experimentally explore the boundaries of altruistic punishment to maintain cooperation by varying both the cost and the impa...

Peer-punishment is effective in promoting cooperation, but the costs associated with punishing defectors often exceed the benefits for the group. It has been argued that centralized punishment institutions can overcome the detrimental effects of peer-punishment. However, this argument presupposes the existence of a legitimate authority and leaves an unresolved gap in the transition from peer-pu...

There are deep, insurmountable difficulties with the traditional interpretation of Immanuel Kantâ??s writings on the subject of punishment. Although it is undeniable that throughout his published writings on practical philosophy â?? and in particular in his Metaphysics of Morals â?? he consistently advocates for the view that punishment can only be justified as a direct response to an individua...

Experimental studies have shown that sanctions effectively deter free riding within groups. However, the over-use of costly punishment may actually harm overall welfare. A main reason for over-punishment is that free-riders generate negative emotions that likely favor excessive punishments. In this paper we ask whether the venting of one’s emotions in different ways can reduce the level of exce...

Compliance with laws and regulations depends on the expected penalty facing violators. The expected penalty depends on both the probability of punishment and the severity of the punishment if caught. A key question in the economics of crime literature is whether increasing the probability of punishment is a more effective deterrent than an equivalent increase in the severity of punishment. This...

To examine how stress affects cognitive functioning, individual differences in trait vulnerability (punishment sensitivity) and state reactivity (negative affect) to social evaluative threat were examined during concurrent reinforcement learning. Lower trait-level punishment sensitivity predicted better reward learning and poorer punishment learning; the opposite pattern was found in more punis...

a r t i c l e i n f o Humans willingly pay a cost to punish defecting partners in experimental games. However, the psychological motives underpinning punishment are unclear. Punishment could stem from the desire to reciprocally harm a cheat (i.e. revenge) which is arguably indicative of a deterrent function. Alternatively, punishment could be motivated by the desire to redress the balance betwe...

AIM To investigate the prevalence, nature, and context of physical punishment and other forms of parental discipline, as reported by study members (SMs) of the Dunedin Multidisciplinary Health and Development Study. METHODS 962 26-year-old adults (born in Dunedin, New Zealand) were interviewed about their experiences of discipline in childhood. Study members were asked about the usual forms o...

The Murder Act (1752) decreed that homicide perpetrators should be hanged and sent for post-execution punishment. This article explores the event management of criminal dissections by penal surgeons in situ. It reveals that the punishment parade of the condemned did not stop at the scaffold, contrary to the impression in many standard historical accounts. Instead, ordinary people accompanied cr...

I criticize an increasingly popular set of arguments for the justifiability of punishment. Some philosophers try to justify punishment by appealing to what Peter Strawson calls the reactive attitudes – emotions like resentment, indignation, remorse and guilt. These arguments fail. The view that these emotions commit us to punishment rests on unsophisticated views of punishment and of these emot...
