Testing how information about cost-effectiveness, cause preferences, and geographic preferences interact to affect philanthropic giving

Abstract

The broad instrumental philanthropy movement advocates for considerations of cost-effective impact in donation decisions. Within that broader movement, the effective altruism movement goes as far as to advocate for cause neutrality and geographic neutrality when prioritizing cost-effectiveness in charity. We present a survey experiment that examined how information about cost-effectiveness, cause area preferences, and geographic preferences interact to affect philanthropic giving. The experiment varied these three dimensions in a hypothetical giving situation and found that cost-effectiveness information had the strongest influence on hypothetical giving. Participants gave most when presented with charities that were shown to be highly cost-effective, local/domestic, and that matched their preferred cause area. Understanding how these three considerations interact to affect donors is important as donors continue to desire more information about the cost-effective impact of their donation.
