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. 'Decision Theory with a Human Face is a major work that unifies and expands on an already impressive body of work from Bradley. It is difficult to think of many major debates in philosophical decision theory to which it does not make significant contributions.' Timothy Luke Williamson, Metascience Explores how decision-makers can manage uncertainty that varies in both kind and severity by extending and supplementing Bayesian decision theory. Richard Bradley is Professor of Philosophy at the London School of Economics and Political Science. He is an editor of the journal Economics and Philosophy, and his work on decision theory, semantics and epistemology has been published in numerous leading journals.
