Mapping and Increasing Americans’ Actual and Perceived Support for Initiatives Protecting Future Generations

Across eight preregistered studies ( N = 6,464), we apply an approach informed by social norm theory to investigate perceptions and realities of support for Initiatives for Future Generations (IFGs)—institutions and policies designed to ensure political representation for and protection of future generations. We find widespread bipartisan support for IFGs alongside pluralistic ignorance: Americans vastly underestimate their peers’ support. Correcting misperceptions enhances individual support, underscoring the role of social norms in shaping collective action. We also find modest—albeit mixed—evidence that interventions aimed at increasing intergenerational concern can boost support for IFGs without exacerbating pluralistic ignorance. These interventions may serve as a complement to norm-corrective approaches by engaging moral motivations alongside informational strategies. Beyond highlighting the value of correcting norm misperceptions in safeguarding future generations’ welfare, we explore motivational explanations for pluralistic ignorance and emphasize that policymakers hold the power to implement IFGs with confidence and the public is behind them.
