In a practical test, people's willingness to help with community projects was found to be higher when they could use their contributions for something specific, instead of dividing it into individual portions, like in a typical game. Their experiment showed that when given the choice, people were more likely to give more by opting to pay for things together as a group, rather than splitting it into separate amounts. This suggests that previous studies may have overestimated how much individuals are willing to pitch in for common causes in real life.
