An experimental study of prosocial motivation among criminals

The fact that criminal behavior typically has negative consequences for others provides a compelling reason to think that criminals lack prosocial motivation. This paper reports the results from two dictator game experiments designed to study the prosocial motivation of criminals. In a lab experiment involving prisoners, we find a striking similarity in the prosocial behavior of criminals and non-criminals, both when they interact with criminals and when they interact with non-criminals. Similarly, in an Internet experiment on a large sample from the general population, we find no difference in the prosocial behavior of individuals with and without a criminal record. We argue that our findings provide evidence of criminals being as prosocially motivated as non-criminals in an important type of distributive situations.
