Social norms of right and wrong are vital to a well-functioning society. However, such moral standards are changeable and the psychological mechanisms（机制）driving this change are unknown. Now, researchers at Karolinska Institutet report that our view of selfish and unselfish behaviors changes depending on how common they are. The results are based on a combination of behavioral experiments, mathematical models and computer simulations. In the experiments, the participants first observed other people’s behavior in a so-called“public goods game,”in which players receive a sum of money and then choose either to invest it to varying degrees so that it benefits everyone in the group, or to keep it for themselves. After every round, the participants

were asked to judge the different choices as morally right or wrong, and whether the choices ought to be punished with a reduction in how much the players gained. Unselfish behavior was considered more morally right than selfish, but both behaviors were judged to be more moral and less deserving of punishment if the majority exhibited them than if they were uncommon. The commonness of the selfish behavior also affected the participants’ willingness to themselves pay to punish selfishness.
“Tolerance of selfish behavior increased when the majority of the players kept the money for themselves, which surprised me,”says principal investigator Andreas Olsson, senior lecturer at Karolinska Institutet’s Department of Clinical Neuroscience.“The fact that a behavior is common doesn’t automatically mean that it’s right – this idea is based on faulty logic that confuses facts with moral values.”
The study shows our view of what is morally right and wrong has strong similarities with social comformity, in that we tend to adapt ourselves to the people around us and how they behave. This means that changes in our social environment can quickly alter our moral compass.
“This is interesting from several angles, and could explain why moral attitudes change over time, such as those towards public goods or legality,”says Bjorn Lindstrom, postdoc at University of Zurich and Karolinska Institutet’s Department of Clinical Neuroscience.
