Effective altruism (EA) is a philosophical and social movement that advocates using evidence and reasoning to determine the most effective ways to benefit others, and then acting on those conclusions. Originating in the early 2010s among philosophers and donors associated with the University of Oxford, it became one of the main early sources of funding, talent, and institutional infrastructure for AI safety and AI-existential-risk research. Its public standing was affected by the 2022 collapse of the cryptocurrency exchange FTX, whose founder Sam Bankman-Fried was a prominent EA donor, and by the November 2023 OpenAI board crisis (Source: https://en.wikipedia.org/wiki/Effective_altruism).
Background
The movement combines a normative claim — that those with resources have strong reason to do as much good as possible — with an empirical program of comparing interventions by cost-effectiveness, drawing on methods such as randomized controlled trials and expected-value reasoning. Its early causes centered on global health and development (for example, evaluations by the charity evaluator GiveWell) and animal welfare. Figures associated with its development include the philosophers William MacAskill and Toby Ord, who co-founded the Oxford-based organizations Giving What We Can and the Centre for Effective Altruism (Source: https://en.wikipedia.org/wiki/Effective_altruism).
A subset of the movement, oriented toward Longtermism, holds that positively influencing the long-term future is a key moral priority and that reducing risks of human extinction — including risks from advanced AI — is among the highest-value uses of resources. This wing connects EA to the existential-risk research tradition associated with the Future of Humanity Institute, the Machine Intelligence Research Institute, and the Future of Life Institute lineage.
Relation to AI safety
EA-affiliated funders became significant early backers of AI safety and AI-governance work. Open Philanthropy, funded primarily by Dustin Moskovitz and Cari Tuna, directed substantial grants toward AI risk reduction, technical alignment research, and AI policy organizations. EA-aligned funds such as the Long-Term Future Fund describe their grants as aiming "to address potential risks from advanced artificial intelligence and to build infrastructure and advocate for longtermist projects" (Source: https://funds.effectivealtruism.org/funds/far-future). The FTX Future Fund, before its 2022 collapse, distributed roughly $132 million in grants, including an estimated $32 million directed to AI safety (Source: https://www.longtermwiki.com/wiki/E855).
The movement also functioned as a talent pipeline, with personnel from EA organizations moving into roles at frontier AI laboratories and AI-governance institutions. Several founders and staff at AI safety-focused organizations describe EA as part of their intellectual background.
Debates and positions
The relationship between EA and AI policy is contested. Civil-rights and algorithmic-justice advocates have argued that EA-influenced prioritization of speculative long-term or existential risks can crowd out attention to documented near-term harms such as bias, discrimination, labor displacement, and mental-health effects — a tension also discussed on Longtermism and in framings such as AI as Normal Technology. Critics within and outside the movement have also debated whether expected-value reasoning over low-probability, high-stakes outcomes can justify almost any allocation of resources.
The movement's reputation was affected by two episodes. The 2022 bankruptcy of FTX, whose founder Sam Bankman-Fried had publicly identified with EA and pledged large sums to EA-aligned causes, led to scrutiny of the movement's funding and governance and to the return or freezing of some grants. In November 2023 the dismissal and reinstatement of OpenAI chief executive Sam Altman drew attention to EA-linked board members, reinforcing a public association between EA and internal AI-lab governance disputes (Source: https://en.wikipedia.org/wiki/Effective_altruism).
More recently, some figures associated with the movement have argued that the rise of a distinct AI safety movement raises questions about EA's continued role. William MacAskill has written that, in light of rapid AI progress, some observers "view EA as a legacy movement set to fade away," while arguing for its continued relevance in an era of advanced AI (Source: https://willmacaskill.substack.com/p/effective-altruism-in-the-age-of).
