The consensus: texts and exhibits in an exhibition have to be scientifically correct. The question: how do we come by this correctness and what does “correct” actually mean? Science Centres and museums often employ teams of experts to ensure the correctness of their exhibitions. The potential problem: experts know the science but not necessarily what makes good interaction, or how visitors behave and react in exhibitions. Still, their knowledge is crucial for the museum. This reverse session will bring together curators, writers, and experts who will be giving short presentations of their experiences to then get into a discussion with the audience on how to make the cooperation between institutions and experts worthwhile for all parties, including visitors.
