Effective Altruism: The Philosophy of Doing Good and Its Critics

A Simple Premise With Complex Consequences

In 1972, Australian philosopher Peter Singer published "Famine, Affluence, and Morality" in the journal Philosophy and Public Affairs. The argument was stripped to its essentials: if we can prevent something bad from happening without sacrificing anything of comparable moral importance, we ought to do it. The geographic and psychological distance between a donor in a wealthy country and a child dying from a preventable disease in a low-income country is, Singer argued, morally irrelevant. The essay became one of the most discussed and assigned papers in applied ethics and helped catalyze a philosophical and social movement that by the 2020s had directed billions of dollars in charitable giving.

The Philosophical Foundations

Effective altruism (EA) draws on utilitarian and impartialist traditions in moral philosophy. The core commitments are three: impartialism (every person's welfare counts equally regardless of proximity, nationality, or relationship), consequentialism (the moral weight of an action is determined by its outcomes), and empiricism about ethics (claims about what produces good outcomes should be held to the same evidentiary standards as empirical claims).

The last commitment drives the movement's characteristic methodology. If two charities both claim to help people, and one can be shown through randomized controlled trials to save a life for $3,500 while another cannot demonstrate measurable impact at any cost, the impartialist consequentialist should prefer the first. Organizations like GiveWell, founded in 2006, apply this framework systematically, publishing detailed cost-effectiveness analyses of global health and poverty interventions.

Major Cause Areas

The EA community has organized around three primary cause areas, selected by applying the criteria of scale (how many beings are affected), tractability (how much can be done about the problem), and neglectedness (how underserved the cause is relative to its importance).

Global health and poverty: the most concrete and empirically grounded area. GiveWell's top-rated charities — including the Against Malaria Foundation, Malaria Consortium, and Helen Keller International's Vitamin A supplementation program — have been estimated to deliver a year of healthy life for $50 to $100. As of 2023, GiveWell has directed approximately $2 billion in donations to high-impact organizations since its founding.

• Global health and poverty: direct, measurable impact through deworming, malaria prevention, and direct cash transfers to the extreme poor
• Animal welfare: approximately 80 billion land animals are raised in factory farms annually; EA funders support cage-free corporate campaigns and alternative protein research
• Longtermism and existential risk: risks that could permanently curtail humanity's future — artificial intelligence misalignment, engineered pandemics, nuclear war — are argued to be of disproportionate importance given the potential scale of future affected beings

Earning to Give: A Controversial Application

One practical implication of EA reasoning — earning to give — attracted particular public attention. If the goal is to do the most good and donating money to effective charities achieves that, then maximizing income to maximize donations can be more impactful than direct work in nonprofits. A software engineer earning $200,000 and donating $80,000 annually to effective charities may do more good than by taking a $50,000 nonprofit salary. Singer, the philosopher most associated with the argument, acknowledged this logic. EA-affiliated organizations like 80,000 Hours publish career advice calibrated to expected impact.

The Critics

Effective altruism has generated substantive criticism from multiple directions. The critique is not simply that its intentions are good but its methods are wrong — the criticisms cut deeper, questioning the philosophical assumptions that make EA's methodology seem compelling.

The legibility problem: Amia Srinivasan and others have argued that EA's insistence on quantifiable, measurable impact systematically disadvantages causes whose value resists quantification — domestic violence advocacy, arts education, community resilience. The appearance of rigor may conceal a bias toward causes that produce numbers, not causes that produce hard-to-measure goods.

Angus Deaton, Nobel laureate in economics and author of The Great Escape (2013), argued that well-intentioned direct aid can undermine local institutions, distort incentive structures, and entrench dependency. The evidence base for aid effectiveness is, he contended, significantly weaker than EA proponents claim. The RCT (randomized controlled trial) methodology GiveWell relies on measures short-term outcomes well but may miss long-term systemic effects. These debates reflect genuine empirical disagreement, not merely philosophical preference.

After FTX: Reputation and Accountability

The collapse of FTX and the criminal fraud conviction of Sam Bankman-Fried in November 2023 created significant reputational damage for effective altruism. Bankman-Fried had been one of EA's most prominent donors and public advocates, pledging billions to EA causes from crypto trading profits. The specific irony — that a philosophy predicated on honest empiricism about doing good had a prominent spokesperson convicted of fraud — generated extensive commentary both inside and outside the movement. EA organizations publicly addressed the episode; the philosophical arguments at EA's core remained unchanged. Whether the institutional and reputational consequences have long-term effects on the movement's trajectory is an ongoing question.
