Commitment
(reading time – 30 sec.)

The tendency to be consistent with what we have already done or said we will do in the past, particularly if this is public.
For example, researchers asked people if they would volunteer to help with the American Cancel Society. Of those who received a cold call, 4% agreed. A second group was called a few days prior and asked if they would hypothetically volunteer. When the actual request came later, 31% of them agreed.
