Master's Dissertation: Can a group be justified in believing a contradiction?

In my dissertation, I argue that groups can be justified in believing a contradiction. I present and motivate a Lockean account of justified individual belief and, on this basis, argue for a mechanism for forming justified group belief which is tailored to peer groups of scientific experts about complex systems such as the climate. Because of the special epistemic circumstances due to, both, the type of groups I consider, as well as their areas of research, justified contradictions on the group level are possible, and sometimes even epistemically beneficial. I conclude by arguing that this result is non-standard, because present accounts of justified group belief do not allow for justified contradictions.
