"I work broadly in decision theory and related fields such as formal epistemology and semantics. Much of my work is on individual decision making under uncertainty and the role of hypothetical reasoning in reaching judgements about what to do. But I am also interested in the nature of the intentional attitudes, belief and preference revision and social value and choice. I have recently begun working on the nature of chance and our attitudes to it (both as individuals and as a society). My other big project at the moment is decision making under severe uncertainty (see below). A lot of this work is brought together in a book entitled “Decision Theory with a Human Face”, recently published with Cambridge University Press"---personal website

When making decisions, people naturally face uncertainty about the potential consequences of their actions due in part to limits in their capacity to represent, evaluate or deliberate. Nonetheless, they aim to make the best decisions possible. In Decision Theory with a Human Face, Richard Bradley develops new theories of agency and rational decision-making, offering guidance on how 'real' agents who are aware of their bounds should represent the uncertainty they face, how they should revise their opinions as a result of experience and how they should make decisions when lacking full awareness of, or precise opinions on relevant contingencies. He engages with the strengths and flaws of Bayesian reasoning, and presents clear and comprehensive explorations of key issues in decision theory, from belief and desire to semantics and learning. His book draws on philosophy, economics, decision science and psychology, and will appeal to readers in all of these disciplines.

Presents a comprehensive treatment of rational decision-making in situations of severe factual and evaluative uncertainty, and develops a unified theory of rational bounded agency

Provides researchers in different fields - philosophy, economics, psychology - with a coherent conceptual framework within which to investigate key issues

Includes clear and detailed presentation of formal and conceptual philosophical material, enabling readers to develop an advanced understanding of the latest research
