Fear of giving too little can stop people from giving at all

This article explores why people often hesitate to make small donations, despite wanting to help. Research led by Jean Zhang, a postdoctoral researcher at the Wharton School, suggests that the issue lies not in a lack of generosity, but in the fear that a small contribution may seem inadequate. This concern is a significant barrier to giving, as recipients are often more than willing to accept less than what donors initially expect.

The study, published in the Journal of Economic Behavior and Organization, involved nearly 2,000 participants across four separate experiments. In one of the studies, participants imagined purchasing a $30 car wash but had only 25 cents or $5 in cash. Nearly 80% of those with only 25 cents decided not to tip, while almost 90% of those with $5 did. This suggests that a small amount of money can feel too insignificant to contribute.

The researchers found that the perceived insignificance of a small donation leads people to worry that their gesture would send the wrong message. To test this theory, they explored whether anonymity would increase the likelihood of tipping. Concealing the tip amount doubled the willingness to give just 25 cents, rising from 30% to 61%. Furthermore, informing participants that the amount was considered an acceptable tip boosted tipping by 22 percentage points.

While the study specifically focused on monetary donations, the researchers believe the findings could extend to other forms of giving. The authors propose that by making small acts feel legitimate, and demonstrating how contributions can accumulate to significant progress, businesses and organizations can help overcome this barrier to generosity.
