Abstract: This study examines the effect of the intergroup social comparison approach in promoting water conservation. In an online survey experiment, participants first encountered normative persuasive messages, informative persuasive messages, or intergroup social comparison messages and then reported their willingness to conserve water, prior water usage, and demographic information. Results showed a significantly higher willingness to conserve water in the intergroup social comparison condition compared to other conditions. We further investigated whether this social comparison effect was moderated by prior water usage and the strength of comparison. Results suggest that prior water usage, rather than the strength of comparison, moderated the influence of intergroup social comparison. Moreover, the moderating effect of prior water usage only works when participants receive a low level of strength of comparison.
