Schoar collected the best rules of thumb and designed a different “financial education” class based on them. Her class was shorter and much easier to grasp. It used a lot less bandwidth, and this showed up in the data. Attendance was much higher, and at the end of the rules-of-thumb class, clients were ecstatic and asking for more; many even said they would pay for another class themselves. Normally, you have to cajole people to come back to a class on financial education.
