"We behave as if we were the types of people who are seeking knowledge"

Known as the "foot-in-the-door" technique, this approach works because the small initial request (to wear the T-shirt) will cause the person to act in accord with message it promotes. This encourages them to believe they are knowledgeable people and so motivates them to learn.
