As a part of the Umea university #FrAIday seminar series about AI, Prof. Tom Lenaerts will present his work on understanding and modeling strategic decision-making in the face of existential risks that has been performed with students and international collaborators within his group in Brussels. The workhorse of this research is the collective risk dilemma (CRD), a formalization of the problem of climate negotiations, wherein the goal is to reach a common good, but selfish considerations may result in failure with potential cataclysmic outcomes.
