Over the last 50 years, psychologists and economists have joined forces to study how people can think and act in way that are more optimal, healthy, and generative. In other words, there is now a science of human flourishing. These various research programs (including programs on behavioral economics, positive psychology, and judgment and decision-making) illuminate how people's decisions, feelings, motivation, and behavior deviate from optimal ways of being, the consequences of such deviations, and what can be done to improve them. This course is a good fit for anyone who is interested in improving their own thinking, motivation, and behavior in the workplace, or the thinking, motivation, and behavior of others.
