Summary: New research finds that people who punish others because they believe it is morally right do not respond predictably to material incentives. Monetary rewards can reduce willingness to inflict harm because taking payment undermines the moral signal of their actions—unless peers affirm that accepting payment does not tarnish their moral standing.

Researchers at the University of California San Diego’s Rady School of Management report that many people who harm others do so because they view violence or punishment as morally justified or even obligatory. As a result, these individuals often do not respond to material benefits in the way traditional deterrence theories predict.
The study has practical implications for criminal justice policy. If offenders act from perceived moral duty, conventional penalties such as fines or incarceration may be less effective than expected at preventing future harmful acts.
“For most offenders, inflicting harm purely for personal gain is not the driving motive,” said psychologist Tage Rai, assistant professor of management at the Rady School and lead author of the study. “When people believe they are right, monetary incentives can actually reduce their willingness to punish because accepting payment makes their motives look selfish rather than principled.
“Take the example of the January 6 attack on the Capitol. Many perpetrators believed the election had been stolen and felt morally entitled to punish those they blamed. Although many of them face material penalties, it is unclear whether those penalties alone will change the underlying moral convictions that motivated their actions.”
Rai’s results, published in the journal Psychological Science, draw on four experiments with nearly 1,500 U.S.-based participants. In an online economic game with real stakes, participants could punish a third party for unfair behavior. When researchers offered a monetary bonus to those who punished, willingness to punish dropped by almost half.
“Monetary gains can conflict with a person’s moral self-image,” Rai explained. “People punish to signal their virtue. When payment is introduced, that signal becomes corrupted: observers and the punishers themselves may interpret actions as motivated by greed rather than justice.”
The experiments also showed that social judgment matters. When peers were told that punishment accompanied by payment still signaled moral virtue, participants’ reluctance to accept payment and punish was reduced. In other words, restoring the moral signal brought back willingness to act.
Rai argues this points to a broader mechanism he calls signal corruption: payment interferes with the prosocial signal that punishment normally communicates, altering perceptions of the punisher’s character and the moral acceptability of punitive acts.
These findings suggest policymakers should consider sociomoral incentives, not just material costs and benefits, when designing interventions to reduce violence and antisocial behavior. Social pressure and efforts to reshape moral narratives may be powerful complements to traditional sanctions.
“If the goal is to reduce violence, governments and community leaders need to address the moral stories people tell themselves to justify harm,” Rai said. “Penalties alone may not change those narratives; shifting peer norms and public moral judgments could be a more effective route to prevention.”

Abstract
Material Benefits Crowd Out Moralistic Punishment
Across four experiments with U.S.-based online participants (N = 1,495 adults), the author found that paying people to engage in moralistic punishment reduces their willingness to do so. In an economic game with real stakes, providing a monetary bonus for third-party punishment of unfair offers nearly halved participants’ willingness to punish.
In judgments of hypothetical transgressions, observers rated punishers who accepted payment as having worse character and judged their punitive actions as less morally acceptable. Willingness to punish was restored when payments were large enough or when participants were assured that payment did not diminish the moral signal of punishment.
The data support a signal-corruption account: payment interferes with the prosocial signal that moralistic punishment normally conveys about a punisher’s motives. These results have implications for the cultural evolution of punishment and suggest that understanding perpetrators’ sociomoral incentives is essential for designing conflict-reduction policies.
