Member of the Knowledge Construction Lab
Aileen Oeberst is head of the Department of Media Psychology at the University of Hagen and a member of the Knowledge Construction Lab of the IWM, where she supervises the project "Collaborative Biases". Her research mainly focuses on biases in collaborative knowledge construction. She examines, for instance, whether Wikipedia articles contain a hindsight bias, that is, whether they erroneously suggest events (such as the nuclear disaster of Fukushima) as inevitable and foreseeable. Beyond that she investigates the consequences of biased Wikipedia articles on readers. She has been awarded grants (e.g., from the German Research Foundation, Leibniz Society) to support her research.
Aileen Oeberst studied Psychology at the universities of Leipzig and Cagliari (Italy, Diploma 1999). For her dissertation about hypermnesia she went to the University of Osnabrück (2009). In 2012/13 and 2015 she was a visiting professor for Social Psychology at the University of Osnabrück and the Johannes Gutenberg-University of Mainz.
