Effective altruism

2009

Effective altruism isn’t about caring more—it’s about calculating who gets to matter, and why.

Effective altruism is a philosophical and social movement that originated in the latter half of the 2000s in the Anglosphere, coalescing around converging communities and formally named in 2011. It is defined by impartial calculation of benefits, cause prioritization, and commitment to evidence and reason. Key institutions include the Centre for Effective Altruism, founded in 2011, and its associated conferences beginning in 2013. Its unifying principles are prioritization, impartial altruism, open truthseeking, and a collaborative spirit.

    A movement, not a mood

    It is a 21st-century movement—not a revival, not a reaction, but a new formalisation of moral action.

  2. 2:02
    Built, not born

    It began not with a manifesto but with infrastructure: two groups voting on an umbrella name in 2011.

  3. 3:31
    Three axioms, no exceptions

    Its method is its message: evidence, reason, and global impartiality are non-negotiable starting points.

  4. 5:10
    Rituals follow names

    Its first major public ritual—the EA Global conference—began in 2013, three years after its naming.

The written brief1 min read

What the thing is

Effective altruism is a philosophical and social movement. It uses evidence and reason to maximise benefit to others. It applies global equal consideration of interests. It prioritises causes by expected impact.

Where it came from

It emerged from converging communities in the latter half of the 2000s. These included altruist, rationalist, and futurological groups. The name ‘effective altruism’ was coined in 2011. The Centre for Effective Altruism formed that year.

What it gets right

It treats altruism as a skill to be trained, not a feeling to be trusted. It forces explicit trade-offs between causes. It insists on global impartiality, not charity-as-self-soothing.

What it gets wrong

It assumes evidence and reason are neutral tools, not shaped by the institutions that produce them. It displaces local knowledge with remote calculation. It offers no account of power beyond inefficiency.

Why it matters now

Because it codifies a dominant mode of contemporary ethics: quantified, scalable, institutionally legible, and detached from place, history or reciprocity. It is the operating system for a certain kind of tech-adjacent philanthropy—and its limits are now visible in practice.

Is it worth your time

Yes—if you care about how moral reasoning is formalised, tested and scaled in real time. No—if you expect historical sweep or cultural texture.

Adbusters1989Adbusters is a Canadian anti-capitalist activist foundation founded in 1989 in Vancouver by Kalle Lasn and Bill Schmalz. It uses culture jamming—especially subvertisements and campaigns like Buy Nothing Day and Occupy Wall Street—to challenge consumerism and corporate control of information flows. It publishes the reader-supported, advertising-free Adbusters magazine. Its founding premise is that citizens lack equal access to information flows compared to corporations.

Crypto-anarchyCrypto-anarchy is a movement, not a prophecy. It uses cryptography to enable anonymity, free speech and trade. It emerged from Timothy C. May’s 1988 manifesto and the 1992 cypherpunk founding. It gets right that code can constrain power—but wrong that it will collapse the state. A 2022 study confirms its political irrelevance—yet its architecture remains vital for Internet-native dissent.

Culture jammingCulture jamming is anti-consumerist protest that uses détournement to subvert corporate media forms. It began in the 1950s, was named in 1984 by Don Joyce of Negativland, and draws directly from the Letterist and Situationist Internationals. It correctly identifies media as a tool of perception-shaping and conformity-enforcement. But it wrongly assumes irony alone can resist power—and ignores how quickly its tactics are absorbed into branding. It matters now because corporate language has colonised every channel of attention, yet its methods remain stuck in the logic of the 1980s media landscape. It is worth your time if you want to understand why resistance so often looks like the thing it opposes.

Free software movementThe free software movement is a precise, principled refusal of proprietary control over software. It began in 1983 with GNU and institutionalised in 1985 with the FSF. It gets right that software freedom must be guaranteed—not merely permitted. It gets wrong that licence compliance alone secures user agency. Its relevance has grown as software becomes infrastructural—but its methods remain rooted in individual refusal and collective development.
