Orri Stefánsson did his undergraduate studies in philosophy and economics at the University
of Iceland and the Technische Universität Berlin. After graduating in 2007, he worked as a
journalist for a couple of years, after which he moved to London to do an MSc in Philosophy
and Public Policy and a PhD in Philosophy, both at the London School of Economics and
Political Science. After completing his doctoral studies in 2014, he was a Postdoctoral Research
Fellow at FMSH in Paris, where he was associated with the Chair for Welfare Economics and
Social Justice and the Franco–Swedish Program for Philosophy and Economics. After that,
he took up a position as a Researcher at the Institute for Futures Studies in Stockholm, and
then an Assistant Professorship at the University of Copenhagen. Since 2019 he is an Associate
Professor of Practical Philosophy at Stockholm University, Research Fellow at the Institute for
Futures Studies and (from July 2019) Pro Futura Scientia Fellow at the Swedish Collegium for
Advanced Study. He is also a regular Visiting Fellow of the Australian National University in Can-

Stefánsson works on decision theory, the philosophy of risk, and Bayesian epistemology. He has
published both in interdisciplinary journals, such as Risk Analysis and Economics and Philosophy,
as well as in leading philosophy journals, such as Mind, Synthese, Philosophy of Science, AJP, and
British Journal for the Philosophy of Science. He is moreover in the process of writing (with
Katie Steele) a book entitled Reasoning with Unknown Possibilities, which will be published by
Cambridge University Press. Stefánsson’s current research mostly concerns how one should
choose in situations of severe uncertainty, including in situations where one suspects that the
outcomes of one’s actions (or inaction) could be catastrophic.

Stefánsson’s Pro Futura Scientia project is entitled Decision-Making at the Extremes: Environ-
mental Catastrophes and Radical Uncertainty
