This course focuses on normative approaches to decision making. In the main part of the course, students examine how rational agents and intelligent systems should make decisions according to rational decision theory, game theory, and social choice theory. Students also choose one of two additional short modules, focusing on either descriptive decision theory or information security. In the short descriptive decision theory module, students examine the psychology of human decision-making, including heuristics & biases, ecological rationality, prospect theory, and nudging. In the short information security module, students examine cryptographic security and privacy technology and policy.
