RATIONALITY, INTELLIGENCE, AND BAYES

The philosopher Nicholas Rescher called rationality "the survival instrument of the human species." A deeply held conviction about the importance of rational inquiry lies at the core of the scientific enterprise. This talk begins with a brief overview of the evolution of Western views of rationality. The evolution of probability and utility theory as a calculus of rational belief and action is discussed. Challenges to Bayesian decision theory are reviewed, including claims of descriptive inadequacy, failure to capture important aspects of intelligent thought and behavior, and infeasibility due to bounded complexity of real agents. The talk concludes with a discussion of the relationship between rationality and intelligence, and the role of Bayesian decision theory in the study of intelligent agency.
