The other two groups were much less likely to give blood. That came as a surprise but we believed a good explanation for this is that if people don’t think anyone will notice, they are more likely to give blood when they expect to get paid. However, we also found that nearly as large a share – 2.4% – of the people in the group that simply heard that they’d get a $10 gift card if they gave blood took part as well. We found that 2.51% of the people who knew they would leave the blood drive with blood-donor branding on their arms and were given the Heart Month rationale for the $10 gift card took part. We predicted that descriptions would work best when they emphasized that a donor’s generosity would be publicly observable and also let donors feel generous rather than in it for the money.Ĭhapman: We predicted that the most effective message would be the one that makes donors feel that others can see that they’ve done a good deed in combination with implying that the gift card is not payment for donation but rather a celebration of American Heart Month.Īnd it was. Instead, we tested how the description of that $10 affected everyone’s decision to donate or not, as well as the power of the expectation that others will know you’ve donated. In addition, only half of both groups were told they would wear conspicuous heart-themed bandages and arm wraps to spread awareness of the importance of giving blood.īecause everyone was offered the same sum, we didn’t compare groups that did versus didn’t get offered money. We expected the Heart Month rationale to make people feel that they were really donating their blood to help people and just happened to be getting a gift card incidentally because of the timing. The other half heard that the gift card was meant to promote American Heart Month, which occurs every February. Half the participants were told the gift cards were intended to thank them for donating blood. The email inviting them to give blood described the gift card in one of four ways. How did you test whether paying blood donors matters?Ĭhapman: In a study I conducted with social psychologist Jeffrey DeWitt, 4,528 members of Rutgers University’s faculty, staff and students were offered a US$10 gift card for taking part in a blood drive on campus. Just like you’d be happy to help your neighbor move a sofa into a truck as a favor, and might be put off if they offered a little cash, you would probably not agree to move the entire contents of the neighbor’s house without being paid for your labor. Not only is there no plasma shortage, the U.S. As a result, it’s common for Americans to get paid for donating plasma – especially low-income people. There’s a third motive: appearing generous to others.Ĭhapman: It takes more time to donate plasma, the pale yellowish liquid that makes up more than half of blood, which means plasma donation requires more effort. That’s because behavioral scientists find that many people do generous things, whether it’s volunteering at an animal shelter or giving hundreds of dollars to their alma mater, based both on a desire to help others and their hankering for whatever they think they might get in return. I believe that the current system makes sense. Blood donors are far more likely to get tote bags or bumper stickers as tokens of appreciation. However, it’s an unusual although technically legal practice in the United States. Paying blood donors might seem like a straightforward way to encourage people to do more of it.
