MAIN RESEARCH INTERESTS

01
Cooperation
Why do people cooperate?

The greatest challenge for all societies, regardless of how advanced they are, is to ensure and 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. Despite this 'dilemma', empirical research has consistently shown that people frequently cooperate with each other, even if they do not know each other. My research is aimed at answering the question why people cooperate with others....

02
Reward & Punishment
Why are people (un)willing to reward cooperation and punish non-cooperation?

One of the most straightforward ways to protect the collective welfare is to use sanctions. Numerous experiments have consistently shown that positive sanctions (rewards) for cooperation and negative sanctions (punishments) for non-cooperation can effectively enhance cooperation. Although this is an important insight, a critical question remains: Are people actually willing to sanction? This question is of critical importance, if only for the obvious reason that someone should first be willing to administer rewards and punishments before they can show their effects. My research is aimed at answering the question why people are (un)willing to reward cooperation and punish non-cooperation....

03
Double standards
Why do people apply double standards?

Double standards seem widespread throughout society. However, how fundamental are double standards to humans? When and why do humans apply double standards? And what are the possible consequences to institutional functioning? My research is aimed at answering these questions....

04
Performance ratings
Why are people subjective when rating peformance?

Supervisory job performance ratings play a crucial role in most organizations' personnel decisions. However, supervisory job performance ratings are not necessarily an accurate representation of actual job performance because they are prone to cognitive biases. What are these cognitive biases? Why do they have an impact on job performance ratings? And how can we prevent these biases from happening? My research is aimed at answering these questions....
