More than just your name: Public donations drive inferences of egoistic and altruistic motives

Abstract

The present research shows that public (vs. anonymous) donations are viewed as a sign of egoistic motives, such as wanting to impress others. In addition, such public donations also are viewed as a sign of altruistic motives, such as wanting to encourage others to donate. These perceptions inform inferences of donors' communal traits, with egoistic motives suggesting weaker communal traits, and altruistic motives suggesting stronger ones. Inferences of communal traits impact behavior, with stronger communal traits predicting greater charitable donations. In sum, public modes of giving can decrease donations (through inferences of egoistic motives and weaker communal traits) and increase donations (through inferences of altruistic motives and stronger communal traits). These effects occur in the context of $100 and $10 donations (Study 1) and impact real contributions of money (Study 2) and volunteer work (Study 3). Platform managers can strengthen inferences of altruistic motives by communicating that public donations can motivate others to give (Study 4). Together, these findings enhance understanding of how public forms of giving influence others to donate, which has practical implications for donation platform managers.
