Does AI and human advice mitigate punishment for selfish behavior? An experiment on AI ethics from a psychological perspective
People increasingly rely on AI-advice when making decisions. At times, such advice can promote selfish behavior. When individuals abide by selfishness-promoting AI advice, how are they perceived and punished? To study this question, we build on theories from social psychology and combine machine-behavior and behavioral economic approaches. In a pre-registered, financially-incentivized experiment, evaluators could punish real decision-makers who (…
Too Lucky to Be True
Income inequalities within societies are often associated with evidence that the rich are more likely to behave unethically and evade more taxes. We study how fairness views and preferences for redistribution are affected when cheating may, but need not, be the cause of income inequalities. In our experiment, we let third parties redistribute income between a rich and a poor stakeholder. In one treatment, income inequality was due only to luck, w…

Guilt drives prosociality across 20 countries
Fostering trust
The peer-to-peer lending and transfer of underutilized resources - the so-called Sharing Economy - make up for a sizeable and rapidly increasing portion of the economy. The digital platforms that enable it have the primary goal of promoting trust among users and providers. In an online experiment, we study how the platform’s revenue model (No-profit vs. For-profit) interacts with its communication strategy in shaping trust. In particular, we cons…
Risks and protective measures for synthetic relationships
Ignorance by choice
People sometimes avoid information about the impact of their actions as an excuse to be selfish. Such "willful ignorance" reduces altruistic behavior and has detrimental effects in many consumer and organizational contexts. We report the first meta-analysis on willful ignorance, testing the robustness of its impact on altruistic behavior and examining its underlying motives. We analyze 33,603 decisions made by 6,531 participants in 56 different t…
Giving (in) to help an identified person
People give more to a person in need when this person's identity is known. Such altruistic behaviors may arise from a genuine concern for the person, leading people to give. Alternatively, altruistic behavior may also arise from one's attempt to reduce the guilt of not giving, leading people to give in. Is the increased altruism towards an identified (vs. unidentified) charity recipient driven by a genuine concern for the person or by guilt? The …
Collaborative dishonesty
10,923). We provide an overview of all tasks used to measure collaborative dishonesty, and inform theory by conducting moderation analyses. Results reveal that collaborative dishonesty is higher (a) when financial incentives are high, (b) in lab than field studies, (c) when third parties experience no negative consequences, (d) in the absence of experimental deception, and (e) when groups consist of more males and (f) younger individuals. Further…

High‐powered Contracts, Self‐selection and Welfare in Settings with Externalities
We extend the experimental analysis of sorting and effort effects of high‐powered contracts on welfare to situations with negative externalities. Participants solve brainteasers from Raven's matrices. The difference between right and wrong answers represents our measure of welfare per capita. We compare two contract schemes: fixed‐wage and bonus contracts that reward subjects for the number of correct answers, regardless of the number of wrong an…
Social norms of corruption in the field
Corruption in the form of bribery continues to be a major societal challenge around the world. The current lab-in-the-field study tested whether dynamic descriptive norms messages on posters can help to reduce bribery. Before, during and after placing posters throughout a medium-sized South African town, incentivized measures of social norms and bribery were assessed in a mobile lab. A total of 311 participants stemming from the general populatio…

Doing Bad to Look Good
Plusieurs études montrent que les préoccupations d’image sociale stimulent les comportements prosociaux. Nous étudions un contexte dans lequel il existe une incertitude sur l’action qui est prosociale. La quête d’une meilleure image sociale entre alors potentiellement en conflit avec le comportement prosocial. Ce conflit peut induire un « mauvais » comportement, où les individus réduisent leurs gains monétaires et ceux des autres afin de préserve…
Is the victim Max (Planck) or Moritz ? How victim type and social value orientation affect dishonest behavior
Does the potential victim of dishonest behavior—a family or a bank, a pensioner or an insurance firm—affect the propensity to engage in such behavior? We investigate the effect of victim type—an individual person or an impersonal institution—on dishonest behavior and test whether it interacts with potential perpetrators' social value orientation (prosocial or proself). In a between‐subjects design, we allowed experimental participants (N = 368) t…
