Correcting for bias in supervision

The decision-making of supervisors (in Dutch: ‘toezichthouders’) is of great importance to effectively manage risks within institutions or markets that are under regulation. In my PhD project, I aim to identify blindspots in supervisory decision-making at the individual and group level. Because this topic has almost exclusively been examined from a governance and legal perspective, this project takes a novel approach by applying psychological insights to supervisory practice. By using various methods (e.g., vignette experiment, decision-making task, longitudinal questionnaire), I investigate to what extent supervisors fall prone to overconfidence bias. I also examine whether popular decision-making tools are effective in improving group decisions and what role leaders can play in creating optimal conditions for decision-making in supervisory teams.
The PhD research is completed on 12 May 2022.
