I study a variety of research topics. Some of them center around power. In my research, I try to give a more complete picture of the way in which having (versus lacking) power affects people's behavior and cognition. I was awarded an NWO VENI-grant (until May 2013) to study the link between power and immorality.
IMPORTANT: Regarding the scientific fraud of my former supervisor Stapel: the committee Levelt has investigated all my work with Stapel. All my work on the topic of power has been cleared from suspicion of data-fraud. This research is all based on data that I collected myself or collected together with other co-authors (i.e. not Stapel). There is one paper (on racism in legal decisions) where I was misled. This paper contains false data. It is currently being retracted.
