Political Common Ground on Preserving Nature: Environmental Motives Across the Political Spectrum

Abstract

Environmental issues are becoming increasingly politically polarized, making common ground essential. This research investigated the political common ground of environmental motives—the reasons why nature is worth preserving. Natural language processing of liberals’ and conservatives’ open text responses (Study 1: N = 1,544) identified 12 central motives. Political common ground was shared on the most cited motives: Human survival, moral obligations to future generations, and appreciation for nature’s beauty. Political differences emerged on motives related to climate change risks and religious stewardship. Study 2 (N = 796) replicated these findings using a validated self-report questionnaire based on participant responses in Study 1. Factor analysis indicated motives belonged to four categories: Responsibility to nature, instrumental benefits, childhood experiences, and religious stewardship. These motives explained substantial variance in environmental attitudes and partially accounted for political differences in attitudes. The studies used mixed methods and direct/conceptual replication to build confidence in key findings and longstanding theoretical frameworks.
