Downward Social Comparison Increases Life-Satisfaction in the Giving and Volunteering Context

Using samples of U.S. residents recruited from an online subject pool, this research confirms that charitable behavior is associated with higher life-satisfaction based on a retrospective survey (Study 1). Adopting experimental manipulation, we also find that participants report higher life-satisfaction after volunteering for a downward comparable target (i.e., the poor) than helping a non-comparable target (i.e., Wikipedia). But the above effect exists only among high social-comparison individuals (Study 2). Moreover, among people high in social comparison, comparing oneself with a downward comparable target without helping can lead to a similar level of life-satisfaction as helping the target. In contrast, participants who are low in social comparison achieve higher life-satisfaction when comparing themselves to rather than helping the target (Study 3). These findings suggest that charitable giving and volunteering contributes to life-satisfaction through allowing for downward social comparison.
