In general, our justice system provides two types of reactions when justice is not served: punishing the perpetrator or compensating the victim. The present study focuses on outsiders observing a situation of injustice. We directly compare punishment and compensation behavior by introducing a...

In two experiments we studied the relation between dependency and deception in the ultimatum bargaining game. Participants could deceive the other player about the value of the chips they bargained over. Dependency was manipulated by manipulating the consequences of rejecting a proposal for both...

In this paper, we introduce the concept of faultline solo splits. Faultline solo splits occur when a demographic dividing line in a group separates a single dissimilar group member from a larger subgroup of demographically similar members, as opposed to separating two dissimilar subgroups as has...

The current study tested the boundary conditions of ethical decision-making by increasing cognitive load. This manipulation is believed to hinder deliberation, and, as we argue, reduces the cognitive capacity needed for a self-serving bias to occur. As telling a lie is believed to be more...
