The Role of Gratitude in Motivating Intergenerational Environmental Stewardship

Abstract Many of the most pressing environmental challenges we face—from climate change to habitat and species loss—require present generations of decision-makers to act pro-socially in the best interests of future generations. One factor known to inhibit intergenerational altruism is the absence of direct reciprocal exchange between generations. Research has suggested, however, that present decision-makers can be induced to engage in intergenerational reciprocity ( Wade-Benzoni, 2002 ). In accordance with recent studies (e.g., Watkins & Goodwin, 2019 ), our current investigation provides additional evidence for the role of gratitude as a powerful mechanism underlying such intergenerational decision-making. Across seven studies, we consistently show that individual differences in gratitude uniquely predict increased perceptions of responsibility for future generations. A sense of responsibility toward future generations in turn predicts: increased climate change beliefs and concern (Studies 2A and 2B), increased pro-environmental beliefs (Study 3A) and environmental intentions (Study 3B), and increased support for environmental policies (Study 4). Indirect effect tests and structural equation models support these findings. Future interventions can harness the prosocial moral emotion of gratitude to combat the temporal discount and promote intergenerational environmental decision making.
