Richard Bradley is Professor of Philosophy in the Department of Philosophy, Logic and Scientific Method at the London School of Economics and Political Science. His research is concentrated in decision theory, formal epistemology and the theory of social choice but he also works on conditionals and the nature of chance. His book Decision Theory with a Human Face gives an account of decision making under conditions of severe uncertainty theory suitable for rational but bounded agents. In recent years he has been doing work on policy decision making under scientific uncertainty applied to climate change, natural catastrophes and the COVID-19 pandemic.
