An experiment with solicitors for contributions to the American Cancer Society. They reasoned that if they could get people to contribute anything, they might get them to contribute more. Thus, they had two teams of solicitors (each team consisting of a male and female college student) use a standard request ("I'm collecting money for the American Cancer Society. Would you be willing to help by giving a donation?"). Another two teams used the same approach, but added the phrase "Even a penny will help" at the end- What compliance technique is this?

Cialdini and Schroeder suggested that saying "Even a penny would help" was the equivalent of asking for a small favor, and once a person had made the decision to help, he or she would actually contribute a larger amount to avoid appearing cheap
