If you’re raising support for a cause, try to get potential donors to feel that they’re giving something of themselves, suggests research by Minjung Koo of Sungkyunkwan University in South Korea and Chicago Booth’s Ayelet Fishbach.
“People who give something that represents their essence—for example, an item they owned for a while versus only briefly—feel more committed to the cause and believe they are more generous,” says Fishbach.
Fishbach and Koo tested this in five donation studies. In one, they gave each participant (a college student) a pen in return for filling out a survey. They then asked whether the student would donate the pen to a charity that provided pens for kids in Kenya and Sri Lanka. Students told at the beginning of the study that they could keep the pens, who therefore felt ownership longer, felt more generous and more committed to the charity to which they donated the pens than those who owned the pens for the shorter period.
A similar sentiment was displayed when people were asked to either sign a petition with their names or support it anonymously. Those who signed said they felt more generous and would be more committed to the cause in the future.
