Post-doc Hwayong Shin has co-authored a new article published in the journal, Political Psychology.
The article, titled, "Do “warm glow” feelings affect climate mitigation behaviors? A field experiment on consumer electric energy choices," examines whether "warm glow" messaging – defined as "the pleasure and satisfaction that one experiences from acting sustainably" – motivates consumers to opt for greener, but more costly, options for their energy choices. Drawing on a field experiment in Hanover, NH, the study provides new behavioral evidence on the real-world impact of appeals to intrinsic motivation in environmental policy.
The article is co-authored with Jennifer Jerit and Jason Barabas (Dartmouth College), Molly Gahagen (Princeton), and Scott May (Community Power Coalition of New Hampshire).

Abstract:
Addressing the climate crisis is going to require behavioral change in many aspects of daily life. A growing literature suggests the promise of “warm glow” messaging that features the pleasure and satisfaction one experiences from acting sustainably. Yet previous research has relied almost exclusively on self-reported behavioral intentions, leaving open whether such appeals meaningfully affect real-world, costly choices. We partnered with a local organization to conduct a field experiment on energy choices in Hanover, New Hampshire. Using a randomized roll-out design in early 2025, we systematically varied the timing of postcard mailers that contain a warm glow message encouraging customers to increase the renewable content of their energy option. Analyses of administrative data on consumer energy choices reveal that warm glow messages delivered in a field setting have a null effect on adoption of higher-renewable power choices, with a small number of customers changing to the greener but more costly option. Our study provides novel behavioral evidence on the real-world impact of intrinsic motivation appeals in the climate domain.
