Welcome to the seventh episode of the Portugal Street Philosophy Podcast, the official podcast of the LSE Philosophy Society. In each episode, we take an important philosophical question and explore our best current attempts to answer it. For this episode, our question is “How should we make decisions under uncertainty?” and our guide to the topic is Professor Richard Bradley. 

In this episode we discuss:

• The relationship between descriptive and normative decision theory


• Expected utility theory


• Rationality constraints and representation theorems


• vNM and Savage’s representation theorems


• Foundationalism vs. reflective equilibrium


• Idealizations within expected utility theory


• Confidence, resilience, and the paradox of ideal evidence


• Unawareness, cluelessness, and ‘medium-termism’


• Evaluative uncertainty


• The relationship between ideal and bounded rationality
