Short Summary

The greatest challenge for all societies is to protect the collective welfare. This challenge arises from the fact that the interests of the collective do not necessarily coincide with the personal interests of the people belonging to that collective. Thus, on many occasions, people face a dilemma between furthering the collective interests or furthering their personal interests. Situations that revolve around this conflict of interests are called social dilemmas. To enhance cooperation in social dilemmas, sanctions readily come to mind as effective solutions. Whereas positive sanctions (i.e., rewards) for cooperation and negative sanctions (i.e., punishments) for non-cooperation can be effective means, a prerequisite for any effect of rewards and punishments is, first and foremost, that people are willing to administer them. To shed more light on this important – yet long neglected – topic, the central theme of this dissertation is the (un)willingness to reward cooperation and punish non-cooperation. In this work, Welmer Molenmaker reports the results of a series of experiments aimed at identifying determinants of the willingness to sanction in social dilemmas. The determinants that he identified reveal that there are not only psychological processes at play that foster sanctioning, but also psychological processes that hamper sanctioning. By taking a closer look at people’s (un)willingness to incur the costs of rewarding cooperative choice behaviour and punishing non-cooperative choice behaviour, this dissertation provides a more comprehensive view of the potential that sanctions can have to solve social dilemmas in the real world.
