Member of the Knowledge Construction Lab
Jort de Vreeze started working for the IWM as a PhD research fellow in February 2013. As of April 2017, he started working on the project: “Collaborative Biases”. In this project he is mainly interested in audience tuning (i.e., how people tailor their communication to suit an audience’s knowledge and attitudes) in collaborative contexts (e.g., Wikipedia). Before that, he worked on the project “The dark and bright sides of disidentification: Antecedents and consequences”. In this project he focused on perceived differences between the self and the group as an antecedent of disidentification; and on the negative consequences of disidentification on information processing.de Vreeze, J., & Matschke, C.
