The Foundational Research Institute (FRI) is a research group affiliated with the Swiss/German Effective Altruism Foundation. It investigates cooperative strategies to reduce risks of astronomical suffering in humanity's future (s-risks). This includes not only (post-)human suffering, but also the suffering of non-human animals and potential digital sentience. Their research is interdisciplinary, drawing on insights from artificial intelligence, anthropic reasoning, international relations, sociology, philosophy, and other fields.
