An Undergraduate Economics Course on Belief Formation and Influence.

The author of this article describes a game-theory-based economics class on how people should, and do, form beliefs, communicate, and make decisions under uncertainty. Topics include Bayesian and non-Bayesian belief updating, the value of information, communication games, advertising, political media, and social learning. The only prerequisite is introductory microeconomics. The course also seeks to convey both the value of thinking in probabilities and awareness of mechanisms of strategic influence in students' everyday lives.
