Those members who were told that another donor had contributed $300 gave an average contribution of $119.70 while those in the same group who were not told about the other donor’s contribution (the control group) gave $106.72. This $13 difference “would translate into a 12% increase in revenue for the station had all callers been offered the $300 social information,” the researchers note.
