Guest Post: High Risk, Low Reward: A Challenge to the Astronomical Value of Existential Risk Mitigation
Written by David Thorstad , Global Priorities Institute, Junior Research Fellow, Kellogg College
This post is based on my paper “High risk, low reward: A challenge to the astronomical value of existential risk mitigation,” forthcoming in Philosophy and Public Affairs. The full paper is available here and I have also written a blog series about this paper here.
