The project

Our project seeks to study decisions and behaviours under radical uncertainty, i.e. when the agents cannot fully grasp the set of possible scenarios. To do that, we will rely on a methodology which has a cross-disciplinary approach at its centre: The core characteristic of radical uncertainty - the unconceivable nature of some scenarios will be reproduced in practice by confronting decision-makers with highly heterogeneous, unfamiliar cognitive perspectives, that only a cross-disciplinary approaches can bring about. A scenario that is not conceivable for a given type of agent may not be (fully) inconceivable for some other types of individuals (ex. experts in an external field, scientists, authors, etc.). To overcome the elusiveness of radical uncertainty understood as the inability to design some almost unconceivable consequences to emulate radical uncertainty, we will rely on the heterogeneity of the world representations provided by different types of expertise and knowledge. Therefore, the project will be two-fold, first it will document almost impossible and radical scenarios, based on this cross-disciplinary approach, and then it will use these scenarios, in various empirical approaches, to observe behaviours under RU.
