The Psychology of (In)Effective Altruism.

The most effective charities are hundreds of times more effective than typical charities, yet few donors prioritize effectiveness. Why is that? How might we increase the effectiveness of charitable giving? We review the motivational and epistemic causes of (in)effective giving. Many donors view charitable giving as a matter of personal preference, which favors decisions based on emotional appeal rather than effectiveness. In addition, while many donors are motivated to give effectively, they often have misconceptions and cognitive biases that reduce effective giving. Nearly all research on charitable giving interventions focuses on increasing donation amounts. However, to increase societal benefit, donation effectiveness is likely to be more important. This underscores the need for research on strategies to encourage effective giving.
