Impartial Intergenerational Beneficence: The Psychology of Feeling (Equal) Intergenerational Concern for All Future Generations.

Across a series of eight high-powered studies ( = 6,866), we develop a method for assessing impartial intergenerational beneficence, defined as intergenerational concern for all possible future generations. Across our studies, roughly 20% of participants displayed impartial intergenerational beneficence. Participants with impartial intergenerational beneficence expressed greater perceptions that future threats can be resolved, support for policies seeking to protect future generations of people, and a profound sense of responsibility for the long-term survival and prosperity of humanity. Similarly, associations with various future-oriented attitudes, patterns of prosociality, and longtermism-related behaviors and intentions were noted. This research thus introduces a method to capture impartiality in expressed intergenerational concern and finds that people who display impartial intergenerational concern endorse prosocial principles, such as altruism and utilitarianism, while also being more concerned about their own future, the future of others, and how they will be remembered by others.
