BIAS OF THE WEEK

Door in the Face Technique

People were asked if they would be willing to chaperone kids from the delinquent program at the zoo for 2 hours. 

Another group was first asked if they would be willing to chaperone kids for 2 hours every week for 2 years. After everyone refused, they were asked to do it one time as the first group. 

People in the second group were 3 times more likely to say yes.

We are more likely to say yes to a smaller request after having said no to a larger one.
