This course looks at the Nudge theory, which was popularized in the 2008 book "Nudge: Improving Decisions About Health, Wealth, and Happiness," written by behavioral economist Richard Thaler, and Harvard Law School professor, Cass Sunstein. The Nudge theory is centered around nudging change in small ways, which can be more effective than trying to enforce it in a traditional sense. The theory is that, eventually, people will choose the needed change for themselves. So, in this program, we'll look at how this theory works and go through the four categories of nudges. We'll also discuss the theory's basic principles and learn how to avoid manipulation, and instead, gently point people in the right direction.
