In some situations, we can make decisions analytically. But more often than not, we do not have the time, the information, or the mental bandwidth to engage in analytical decision-making. Instead, we have to rely on our intuitions and experiences to resolve important decisions. In this course, we will consider various kinds of decisions people must make. We will briefly discuss theories about how people “should” make those decisions. But more importantly, we will learn about how people actually do make those decisions and the ways in which people might come up short of what is “optimal.” The goals are to become better at understanding and predicting how people approach decisions, to identify situations where we can improve our decisions, and (where possible) to use frameworks or tools to more deliberately approach our decisions.
