Intervention (Hidden)
|
Before
Participants viewed one of eight hypothetical charity fundraising messages and were asked to report how likely they would be to donate, and how much they would donate, to the Children’s Literacy Initiative. The eight different messages used in this study differed in two big ways. First, they contained either the message {warm glow: Feed your soul with a gift to Children’s Literacy Initiative. It feels good to make a difference in the life of a child} or the message {altruism: Empower children with a donation to Children’s Literacy Initiative. Help children grow into powerful readers, writers, and thinkers}. Second, messages included one of four different statements about the charity’s progress to toward their goal: no progress reported, 10% completed, 67% completed, 85% completed). We expect to find that messages vary in their effectiveness as a function of the goal progress. Specifically, we expect that people are more likely to donate and donate more when the campaign is close to its fundraising goal and that a warm glow message will be more effective than an altruism message when the goal is closer.

*AMENDMENT: To isolate the effects of the goal, motivational messaging, and the natural preference for the cause, five additional conditions are added for baseline tests: 10% goal completion without motivational messaging, 85% goal completion without motivational messaging, warm-glow messaging without mentioning goal amount or progress, altruism messaging without mentioning goal amount or progress, No goal or motivational messaging.
